Section 1: Foundation of the Study
Plastic recycling is in its developmental stages in Nigeria (Babayemi et al., 2019).
The percentage of plastic waste recycled is low in Nigeria, at 9%, indicating a small
number of plastic recycling businesses (Akan et al., 2021). The population is growing,
bringing about an increase in plastic waste. Private businesses will need to get into plastic
recycling to address the environmental pollution created by plastic waste disposal. Since
plastic recycling businesses are few, the communities and business owners lose wealth
creation opportunities (Kehinde et al., 2020). Plastic recycling businesses that are
profitable can drive efficiencies in the waste management system and instill recycling
behavior in the populace. The improvement in profitability of plastic recycling businesses
can encourage reduced pollution of water bodies and the environment with plastic waste
by communities.
Background of the Problem
Environmental pollution and degradation from plastic waste disposal are growing
in developing countries due to increased population, industrialization, and urbanization
(Babayemi et al., 2019; Olukanni et al., 2020). The state governments of Nigeria are not
providing efficient waste disposal services, and waste disposal businesses provide
disposal services at a cost that everybody cannot afford (Olukanni et al., 2020). Evinemi
and Afon (2016) stated that the percentage of private waste collectors is up by 77.1%.
The designated sites for waste disposal have no requisite capacity to contain the disposed
waste plastics, and there is no plastic waste segregation system in place in Nigeria (see
2
Evinemi & Afon, 2016; Morgan, 2018; Okpara et al., 2021). Consequently, people
dispose of waste plastics indiscriminately in water bodies, streets, and drainages.
There is a need to increase the amount of plastic waste recycled to reduce plastic
waste disposal in landfills and the resulting environmental pollution (Babayemi et al.,
2018). Accordingly, plastic recycling should be profitable for plastic recycling businesses
to be sustainable businesses (Dhanalakshmi, 2019). The improvement in the profitability
of plastic recycling businesses can lead to cleaner streets, create job employment, and
produce high-quality recycled plastic pellets that plastic manufacturers can use.
Problem Statement
Plastic recycling in African countries is in its infancy stage, even though it is a
viable solution for plastic waste management challenges (Babayemi et al., 2019). The
total amount of plastic imported into Nigeria from 1990 to 2017 in primary and
secondary plastics is 39,000,000 tons (Babayemi et al., 2019). Also, Geyer et al. (2017)
projected that less than 12% of generated plastic waste would be recycled globally in
2022. The general business problem was low profitability negatively affects the
percentage of generated waste plastic recycled. The specific problem was that some small
business managers in the plastic recycling industry of Nigeria lack strategies for
improving the profitability of the plastic recycling business.
Purpose Statement
The purpose of this qualitative multiple case study was to explore strategies small
business owners in plastic recycling businesses use to improve profitability. The target
population consisted of nine business owners of nine small plastic recycling businesses in
3
Lagos state of Nigeria who successfully implemented strategies to improve their business
profitability. The implication for positive social change includes the potential to improve
plastic recycling business practices in Nigeria. Consequently, improving business
practices should positively impact profitability, expand existing businesses, and lead to
more job opportunities. Likewise, increased profitability creates more wealth for the
plastic recycling businesses to contribute to society through community projects,
sponsorship for social entrepreneurship programs, and the potential to support
educational scholarship programs in the businesses' communities.
Nature of the Study
The research methods are qualitative, quantitative, and mixed (Strijker et al.,
2020). I used the qualitative method to collect rich data on strategies for improving the
profitability of plastic recycling businesses. A researcher uses qualitative research to
acquire rich data on the research question (Nascimento et al., 2019). A researcher also
uses qualitative research to explore a phenomenon to understand the intrinsic reasons for
a phenomenon in a manner that a numeric empirical method may not address (Kegler et
al., 2019). Qualitative research is interpretive because the researcher needs to elucidate
the subjective and socially constructed meanings expressed about the studied
phenomenon (Saunders et al., 2019). Qualitative research can also be inductive and
naturalistic because the researcher conducts their research in a natural setting (Saunders
et al., 2019). A researcher uses the quantitative method to characterize variables or
examine the degree of relationship between independent variables and dependent
variables (Maciąg, 2019) by defining a hypothesis to prove or disprove characteristics or
4
relationships. Hence, a quantitative method was not suitable for this study because I did
not intend to examine variables' characteristics or the relationship between independent
variables and a dependent variable. Mixed methods research is a blend of qualitative and
quantitative approaches, which combines the analysis of numeric data with rich data
(Meister, 2018). Similarly, a mixed-method approach was not suitable for this research
because there was no reason for combing qualitative and quantitative methods for the
study. Thus, I did not select the quantitative or mixed-method approaches for this study.
Anderson (2017) identified some qualitative designs such as (a) case study, (b)
phenomenology, (c) ethnography, and (d) narrative. A researcher uses a multiple case
study to triangulate data across multiple case studies to compare findings and collaborate
(Cakmak, 2018). Also, a researcher uses a multiple case study to achieve data saturation
(Gaskins, 2019). Equally, the researcher chooses a multiple case study to improve the
validity and reliability of his research. Saunders et al. (2019) mentioned that a single case
design is suited to large businesses that are critical, extreme, or unique. Therefore, I did
not use a single case because the small plastic recycling business does not meet critical,
extreme, or unique criteria. Also, Saunders et al. (2019) stated that single case studies do
not allow the literal replication of findings across cases. Hence, I did not use a single case
study due to the limitation of literal replication across cases but instead chose a multiple
case study. Engward and Goldspink (2020) stated that a phenomenological design
focuses on the meanings of participants' lived experiences. Hence, I did not select a
phenomenological design because the personal meanings of participants' lived
experiences are not the focus of my study. The researcher uses the ethnography design to
5
study a group of people and their culture (Saunders et al., 2019). Researchers use an
ethnography design to explore and document a people or ethnic group's culture, beliefs,
values, and experiences through a written account of observations captured while living
among the ethnic group (Saunders et al., 2019). Therefore, I did not select ethnography
design because I did not study people's cultures or how organizational ethnic groups
interact. Furthermore, I did not select a narrative design for my study because obtaining
information on participants' real-life stories is not the purpose of this study.

Conceptual Framework
I used transformational leadership theory as the conceptual framework for my
study. The originator of transformational leadership theory was Burns (1978). Burns
developed transformational leadership along with transactional leadership.
Transformational leaders inspire followers to excel, while transactional leadership drives
followers by a reward system (Burns, 1978). The transformational leadership style is
relationship-oriented, while transactional leadership is task-oriented. Bass (1985)
extended the work of Burns (1978). The extension of transformational leadership by Bass
in 1985 identified some key elements. Bass stated that transformational leaders affect
idealized influence, have inspirational motivation, stimulate followers intellectually, and
show individualized consideration. Yulianeu et al. (2020) applied a transformational
model to improve the performance of micro, small and medium enterprises (MSME) in
Indonesia. Townsend (2019) used transformational leadership as the conceptual
framework for her study on waste management sustainability in Liberia. Consequently,
owners of small plastic recycling businesses can use transformational leadership
strategies to improve their profitability by inspiring workers to be more productive and
innovative in their work. Transformational leadership is also associated with the
profitability of businesses (Bonsu & Twum-Danso, 2018). Therefore, I applied
transformational leadership theory in this study to identify and understand the strategies
that small plastic recycling business owners use to improve their profitability.

Operational Definitions
Circular economy: Circular economy is an economic system where waste
managers practice the principles of reducing plastic waste by reusing, remaking, and
recycling, thereby curbing environmental pollution through plastic waste disposal and
incineration (Ezeudu & Ezeudu, 2019; Huang et al., 2020).
Life cycle assessment: Life-cycle assessment or life cycle assessment is a
methodology for assessing environmental impacts associated with all the life-cycle stages
of a commercial product, process, or service (Chen et al., 2019).
Municipal solid waste: Municipal solid waste is a mixed stream of waste
consisting of various types of plastic waste, kitchen waste, industrial waste, glass, some
bits of metal objects, and house waste disposed of in dedicated trash bins (Genc et al.,
2019).
Plastic recycling: Plastic recycling is reusing plastic through a recycling process
that can be mechanical or chemical (Jiang et al., 2020; Sikdar et al., 2020).
Assumptions, Limitations, and Delimitations
Researchers use the assumptions, limitations, and delimitations to establish the
research borders and uncover shortcomings, which the researcher could have better
handled (Theofanidis & Fountouki, 2018). Delimitations require challenging the
limitations of the research. Researchers need to be aware of the assumptions, limitations,
and delimitations early in the research and report them to improve the findings and
interpretations (Theofanidis & Fountouki, 2018). Sometimes, it is difficult to differentiate
between the research's assumptions, limitations, and delimitations.
8
Assumptions
A researcher makes assumptions when they cannot verify facts he deems true
(Murchison et al., 2019). An assumption for this study was that a qualitative methodology
researcher could explore the strategies to improve the profitability of plastic recycling in
Nigeria. I also assumed that the selected participants for my semistructured interviews
answered interview questions honestly. Furthermore, I assumed business owners are
interested in strategies to improve their profitability.
Limitations
Limitations refer to the areas where the study is weak, and the researcher cannot
do anything about these areas of weakness (Vargas & Mancia, 2019). A limitation of the
study was that I may have failed to include an interview question that would provide
more vital information on the strategies leaders of plastic recycling businesses used to
improve their profitability levels. A second limitation is generating data from nine plastic
recycling businesses' selected small sample size. Additionally, an extension of the second
limitation was if the selected sample is enough to validate the study's findings from nine
business owners in plastic recycling businesses. The last limitation of the study results
was the participants’ honesty and interest in sharing their knowledge.
Delimitations
Delimitations deal with the study's constraints or boundaries (Theofanidis &
Fountouki, 2018). This study's delimitation was selecting my target sample from
southwest Nigeria, with a higher concentration of plastic recycling businesses.
Participants must be business owners of plastic recycling plants with work experience of
9
no less than 5 years or younger than 25 years. The business owner must also be a
strategic decision-maker in the plastic recycling business. The plastic recycling plants
must have an established supply chain for sourcing plastic waste and clients to sell their
recycled products. I did not consider plastic manufacturing businesses or waste
management businesses.
Significance of the Study
Value to Business
Business owners can use discovered strategies that encourage businesses to adopt
cost-cutting initiatives, and revenue growth can reduce production costs, thereby
increasing profits (Šupuković et al., 2019). The strategies emerging from this study could
enable plastic recycling businesses to improve their profitability by increasing the
effectiveness and efficiencies of key processes and the percentage of generated waste
recycled towards increased profitability. The research strategies can also lead business
owners to automate their plastic recycling businesses and adopt modern technologies to
improve plastic recycling businesses' environmental quality in developing nations.
Contribution to Business Practice
The findings of this study may improve business practice by strengthening the
existing processes for plastic waste disposal and reuse. The strategy for successful plastic
recycling businesses can be documented and replicated by struggling businesses.
Entrepreneurs can have a blueprint for starting a plastic recycling business and managing
it successfully in Nigeria. For example, De Lucia and Pazienza (2019) found that tax
credits, subsidies, and proximity of disposal sites positively impacted Italian farmers'
10
plastic waste recycling process. The federal and state governments can apply this
research strategy to improve and develop the sustainability of small recycling businesses.
Contribution to Positive Social Change
Improving profitability brings better use of waste plastics and may reduce
indiscriminate plastic waste dumping. Also, improving the profitability of the plastic
recycling business may offer employment opportunities in the plastic recycling business.
A profitable plastic recycling business could volunteer services to the community, such
as entrepreneurship training. It may also perform social projects by developing
infrastructural growth in its communities, such as a health center (Lumpkin et al., 2018).
Subsequently, businesses can create jobs and give back to communities (Lumpkin et al.,
2018). By creating additional employment opportunities, living standards can improve
the communities where these plastic recycling businesses operate through corporate
social responsibility (Bello et al., 2019). When plastic recycling businesses improve their
profitability, they can have more available finances to grow their business and increase
their sphere of influence (d'Ambrières, 2019). Also, by creating additional employment
opportunities, the individuals' quality of life may improve in the communities where
these plastic recycling businesses operate.
A Review of the Professional and Academic Literature
The purpose of this qualitative case study was to explore the strategies used by
business owners of small plastic recycling businesses to improve profitability. I focused
my study on addressing the gap in the literature on the profitability strategies of small
plastic recycling businesses. According to my literature review, there are not many plastic
11
recycling studies in Nigeria, so I expanded my search to waste management because
plastic recycling is an aspect of waste management. The peer-reviewed articles by
Ezeudu and Ezeudu (2019), Babayemi et al. (2018), Evinemi and Afon (2016), Horvath
et al. (2018), Kehinde et al. (2020), Okpara et al. (2021), Olusunmade et al. (2019),
Owojori et al. (2020), Oyake-Ombis et al. (2015), and Townsend (2019) provide some
regional research on plastic waste management. I also reviewed the literature on plastic
waste management and business strategies for small businesses in developing and
developed countries.
In this section, I analyze the literature on plastic recycling, waste management,
and business strategies. The organization of this literature review is as follows: (a) the
circular economy framework, (b) generated waste plastics, (c) plastic waste segregation
system, (d) plastic waste recycling policies, (e) recycling behavior, (f) business strategies,
(g) alternatives to plastic recycling, and (h) challenges of plastic recycling. I applied the
concept of timeline maps in the literature review to locate plastic recycling themes. Tang
et al. (2019) used timeline maps to identify themes and compare them across disciplines
in their literature review. I also reviewed the theoretical and conceptual frameworks other
researchers have used in related studies and transformational leadership's conceptual
framework for this study. Research based on transformational leadership may help
researchers understand how small business owners in the plastic recycling sector improve
profitability.
To find relevant journal articles, academic books, and dissertations for the
literature review, I searched the Walden University Library databases Business Source
12
Complete, Academic Search Complete, Medline, ProQuest Central, and ProQuest
Science Journals. I also searched ProQuest Dissertations, Theses Global, Abi/Inform
Collection, Sage Premier, Thoreau Multi-Database Search, and Google Scholar. When
searching the databases, the keywords and phrases included plastic recycling, waste
management, generated waste, recycling behavior, challenges, policies, economic,
circular economy, segregation, strategies, and alternatives. I further sorted search results
to select what was suitable for my topic of plastic recycling. I carried out this second-
level sorting using filters for literature in Africa, and Nigeria, relevant work from
developing and developed nations, and business strategies for small businesses in Nigeria
and the rest of the world.
I reviewed more than 500 resources and identified 218 references for this study.
The literature review contains 224 references consisting of 205 peer-reviewed journals,
two articles, four books, and 13 dissertations. The literature review resulted in 205, or
97%, of referenced sources published within 5 years from the expected completion date
of my study and seven, or 3%, of references, published more than 5 years from my
anticipated graduation date. These 3% references include seminal publications from
Burns in 1978, Bass in 1985 on transformational leadership, and the Belmont report of
1979. I also included four peer-reviewed journals in 2015, such as the research by
Hassanpour (2015), Oyake-Ombis et al. (2015), Nnaji (2015), and Subin et al. (2015),
which provide indispensable information on plastic recycling in Iran, Kenya, Nigeria,,
and technology application to plastic waste segregation respectively.

Transformational Leadership Theory
Transformational leaders’ style consists of four primary aspects. The first aspect
is idealized influence, or charisma, a quality that leaders demonstrate that allows their
followers to trust them (Bass, 1985). The second aspect is inspirational motivation, which
encompasses leaders’ ability to communicate a vision to inspire others. The third aspect
is intellectual stimulation, which refers to leaders’ challenge to their followers to look at
different perspectives to innovate and think outside the box. The fourth aspect is
individualized consideration stimulation. This aspect refers to leaders identifying with
their followers' needs and addressing them to further followers’ development (Bass,
1985). Therefore, the transformational leadership style can bring about innovation in a
business, help workers be more productive, and increase profits for the business.
Transformational leadership can impact workers to perform with qualities that
drive business profitability. Boukamcha (2019) performed quantitative research using a
theoretical framework of transformational leadership to show that transformational
leadership positively influences corporate entrepreneurship patterns in Tunisia. Corporate
entrepreneurship is a construct with many facets and consists of new business venturing,
innovativeness, self-renewal, and proactiveness (Boukamcha, 2019). Boukamcha found
that when transformational leaders stimulate and motivate workers intellectually through
inspiration, they demonstrate innovativeness, proactiveness, and new business venturing.
Hence, intellectual stimulation and inspirational motivation positively impact workers’
new business venturing, innovativeness, and proactiveness, and these aspects of corporate
entrepreneurship can lead to increased business profitability.
14
Transformational leadership has a positive influence on service quality and team
performance. Andersen et al. (2018) found that transformational leadership has a positive
association with the degree of shared understanding of professional quality, positively
associated with a high level of professional quality. Mahdikhani and Yazdani (2020)
found that transformational leadership positively impacts service quality and improves
team performance. Mahdikhani and Yazdani also found that improved performance
positively impacts service quality. Roibu et al. (2019) explained that the efficiency of
transformational or transactional leadership styles in Romanian hotels affects the
business's profitability. Roibu et al. also found that even though transactional leadership
is more prevalent, transformational leadership is desirable for the innovation and
sustainability of Romanian hotels in the long term. Tănase (2020) found that
transformational leadership affects organizational innovation components of creativity,
employee voice, and knowledge sharing. Similarly, Ghasabeh (2021) showed that
transformational leadership positively contributes to knowledge management. These
studies reinforce that business owners can use transformational leadership to improve the
profitability of their business. Good business service quality, knowledge management,
and innovation positively impact business profitability. Therefore the use of
transformational leadership by business owners improves business profitability.
Transformational leadership may provide a lens for clarifying how leaders of
plastic recycling businesses inspire and intellectually stimulate their employees.
Townsend (2019) used transformational leadership as the conceptual framework for a
study on leadership strategies to reduce Liberian waste management businesses'
15
operational costs. Townsend found that recycling was an emerging theme for waste
management in Liberia and suggested that increasing recycling might reduce some of the
challenges and obstacles experienced in waste management. One block is that plastic
waste is a problematic waste stream to dispose of because it is not biodegradable
(Mazhandu et al., 2020). Bush (2019) used a transformational leadership construct in his
study of reducing operations and increasing profitability in the trucking industry. Bush
found that transformational leadership inspires the workers to work at their best during
downsizing exercises. Transformational leadership by business owners gives workers a
vision of where the organization is heading and a sense of ownership in the business
restructuring stages towards increased profitability (Bush, 2019). Therefore, the
transformational leadership theory construct is an appropriate construct for my study and
enabled me to discover the strategies that business leaders use to inspire and motivate
workers to improve their business profitability.
Business leaders reduce worker turnover by using a transformational leadership
style. McManus (2019) used a transformational leadership framework to identify hospital
managers' strategies to reduce employer turnover for environmental services. The author
identified the themes of communication, leadership, training, development, employee
engagement, and profitability. McManus indicated that a transformational leadership
framework may be applicable for studying strategies to improve a plastic recycling
business's profitability. Azizah et al. (2020) discovered that employee optimism partially
mediated the idealized influence of transformational leader behavior on innovative
capability in batik small and medium enterprises in Indonesia. Miftari (2018) further
16
stated that most leaders in small and medium enterprises in Kosovo do not use emotional
intelligence to build strong interpersonal communication and organizational structure
regarding employee performance. Therefore, using transformational leadership by
business leaders can improve the profitability of plastic recycling businesses.
Related and Contrasting Theories
There are many related and contrasting theories that I could have used for my
conceptual framework. In this section, I examine these frameworks and posit why they
were not suited to my research topic. The frameworks I considered in this section are (a)
the interpretive structural model (ISM), (b) product lifetime distribution, (c) the circular
economy, (d) the life cycle assessment model, (e) European Union policies on plastic
recycling, (f) educational models, (g) the biodegradation model, (h) the green supply
chain model, (i) economic models, (j) reverse logistics, and (i) multiple level perspective
theory.
Environmental Models
The environmental models from the list of possible frameworks are circular
economy, life cycle assessment, biodegradation, green supply chain, and reverse
logistics. The main focus of these models was to reduce or eliminate environmental
pollution from plastic waste. Researchers used these models in studies that had a focus on
environmental pollution (e.g., Ezeudu & Ezeudu, 2019; Huang et al., 2020; Nascimento
et al., 2019; Neto & Correia, 2019; Noorhan et al., 2016; Paço et al., 2019; Ren et al.,
2020; Ribeiro et al., 2021; Wei & Zimmermann, 2017; Zhen, 2020; Zheng et al., 2021).
17
Therefore, these models satisfy the environmental conservation criteria of reuse, reduce,
and recycle.
A circular economy is an economic system where waste managers practice the
principles of reducing plastic waste by reusing, remaking, and recycling, thereby curbing
environmental pollution through plastic waste disposal and incineration (Ezeudu &
Ezeudu, 2019; Huang et al., 2020). Nascimento et al. (2019) used the circular economy's
conceptual framework integrated with Industrial 4.0 and supported by sustainable supply
chain management for their research. Industry 4.0 is the fourth industrial revolution in
automation manufacturing. It refers to the internet of things (IIoT) or smart
manufacturing, physical production with smart digital technology, machine learning, big
data, and Cloud to manufacture eco-friendly goods (Zheng et al., 2021). Also, they
proposed integrating smart production systems (SPS) and automated manufacturing
(AM) into a circular economy. The authors interviewed a focus group in operations
management, managers, researchers, and professors. Nascimento et al. found that
adopting a circular business model encourages three-dimensional (3D) printing
technologies and Industry 4.0, such as AM and SPS, in urban waste management. The
study's weakness was that it did not have numeric data to support its recommendations,
and its strength was the focus group's diverse composition and technical competence. A
researcher applying the circular framework focuses on reducing plastic waste, and a
researcher using the Industry 4.0 framework focuses on smart manufacturing.
Furthermore, a researcher in waste management used a circular economy's
conceptual framework to study four different industrial sectors in Nigeria for solid waste
18
generation and disposal (Ezeudu & Ezeudu, 2019). The authors recommended that a
circular economy bring about industry entrepreneurship. The authors found no existing
framework for solid waste management in Nigeria. The strength of this study is that the
findings apply to any research on plastic recycling in Nigeria. Evinemi and Afon (2016)
used a quantitative methodology, questionnaire, and direct observation to study solid
waste generation in Ibadan, Nigeria. Evinemi and Afon discovered improper handling of
solid health waste, substandard waste disposal facilities, and an inadequate disposal
system. I did not use the circular economy or Industry 4.0 as the framework of my study
because my study’s focus is not on reducing plastic waste or the automation of plastic
recycling businesses. Additionally, small plastic recycling businesses may not have the
financial capabilities to use Industry 4.0 in their recycling process.
A researcher uses the life-cycle assessment model for measuring the
environmental impacts involved in all the stages of the life-cycle of a commercial product
(Noorhan et al., 2016). Noorhan et al. (2016) used a conceptual framework of life-cycle
assessment (LCA) and life-cycle software MiLCA to conduct a study. The study is
mixed-method research. The authors carried out data selection using agent-based
modeling. Noorhan et al. found that landfills are no longer sustainable for plastic waste
disposal and that plastic recycling and incineration are more suited to plastic waste
disposal in Bandung, Indonesia. The study's strength is the combination of numeric data
with rich data, and the weakness is that it is limited to Bandung. I did not use this model
because the focus of my study was not the recycled product but the strategies to improve
the profitability of the plastic recycling business.
19
The biodegradation model uses microbial enzymes to degrade plastics (Paço et
al., 2019; Wei & Zimmermann, 2017). Wei and Zimmermann (2017) researched plastic
degradation using microbial enzymes. The theoretical framework used for this research is
the biodegradation model. Wei and Zimmermann tested the degrading effects of
microbial biocatalysts on the different strains of plastics such as polyethylene (PE),
polystyrene (PS), polyurethane (PUR), and polyethylene terephthalate (PET). The impact
of this is worthy of note because if the degradation of plastics becomes economically
viable, it will affect the collection of plastic waste. I did not use the biodegradation model
because the focus of my study was not on alternative forms of plastic recycling, such as
microbial degradation of plastic waste.
The green supply chain model incorporates environmental conservation practices
into supply chain management geared toward environmental sustainability, such as green
purchasing, green distribution, warehousing, green transportation using biofuels, green
manufacturing, and product end-of-life disposal (Zhen, 2020). Ren et al. (2020)
accounted for carbon price uncertainty by combining green supply chain and geographic
information systems (GIS). Ren et al. evaluated their effects on the closed-loop supply
chain of plastic recycling. The maturity model's use assists managers of SME businesses
in the plastic sector in determining how maturity levels match reverse logistics and the
sustainable solid waste management model (Maghmoumi et al., 2020). These studies
buttress the point that a theoretical framework of the supply chain, reverse logistics,
geographic information systems, and maturity models apply to plastic recycling research.
20
The reverse logistics model is for all activities associated with reusing products
and materials and involves moving goods from their normal final destination to add value
to the good or environmentally safe disposal (Ribeiro et al., 2021). Neto and Correia
(2019) assessed the economic and environmental advantages of implementing reverse
logistics to recycle solid waste from construction companies. Neto and Correia used a
reverse logistics theoretical framework and a mixed research methodology. The target
sample was the Brazilian construction and recycling sector. Neto and Correia discovered
that reverse logistics positively impacted the return on investment (ROI), internal rate of
return (IRR), and discounted payback of the construction companies involved in the
target sample. I did not use the reverse logistics model for my conceptual framework
because my research does not focus on reusing recycled products or adding value to
recycled plastic waste and the disposal of recycled plastic at the end of life.
I did not focus on preserving the environment in my study but on the strategies
business owners use to improve the profitability of their businesses. If I used
environmental models, the focus of my study would change from leadership techniques
that business managers use to inspire their workers to improve the profitability of their
businesses to environmental conservation strategies. Consequently, the environmental
models were unsuitable for this study's conceptual framework.
Product Oriented Models
The production-oriented models I considered for this study are product lifetime
distribution, European Union policies on plastic recycling, and educational and economic
models. I classify these models as product oriented because other researchers using these
21
models focused on reusing or reducing plastic waste to reduce environmental pollution
(see Cheung et al., 2017; Faisal et al., 2018, Geyer et al., 2017; Hassanpour, 2015;
Kerscher, 2019; Nakatani et al., 2017; Milios, Christensen, et al., 2018; Milios et al.,
2018; Rowe et al., 2017; Torres & Cornejo, 2016; Warren & Szostek, 2017). The
economic model focuses on the profitability of recycled plastic waste products. The
educational model teaches students recycling behavior on how to dispose of plastic waste
for recycling. The main focus of these models was on how to dispose of plastic waste
sustainably for the environment.
Product Lifetime distribution describes statistical probability distribution
collections researchers use in product life data analysis (see Badr & Ijaz, 2021; Ross &
Cheah, 2019). These distributions could be wholesalers, retailers, and direct-to-consumer
sales (see Geyer et al., 2017; Torres & Cornejo, 2016). Geyer et al. (2017) carried out a
document review of statistics from three plastic market research groups to arrive at the
18% global plastic recycling rate. The author established that plastic recycling rates are
low globally. For their study, Geyer et al. used the theoretical framework of product
lifetime distribution and applied the log-normal distribution (LTD) to analyze their data.
The study's strength was the first global analysis of plastic generation and disposal from
1950 to 2015, with projections on global plastic recycling statistics up to 2050. Torres
and Cornejo (2016) studied plastic recycling in Peru and collected data from the
environment, statistics, customs, and government agencies. The author analyzed the data
using linear regression. The strength of the study was that it analyzed historical data from
22
Peru. I did not use the product life distribution framework because these statistical
probability distributions on plastic recycling businesses in Nigeria were not available.
The European policies established a legal framework for plastic waste treatment
in the EU (Milios, Christensen, et al., 2018; Milios et al., 2018). The main objective is to
protect the environment and human health by implementing recovery, recycling, and
reducing waste. Foschi and Bonoli (2019) used the European Commission's communique
on waste management as their theoretical framework in a study on a policy review of all
related European policies on plastic manufacturing and disposal. The policy review's
fundamental theoretical construct is a circular economy and sustainable development
education on plastics and disposal based on the EU policies on plastic recycling. Milios et
al. (2018), in their study on plastic recycling in Sweden, used the theoretical framework
of EU policy on plastic recycling. Milios et al. found that adapting to the EU targets on
plastic recycling plus a ban on plastics incineration brought about the best optimal
economic benefit combined with low carbon emission for Sweden. The EU policy
framework does not apply to my study because the regional focus of my study was on
Nigeria, where the waste management legal framework for plastic waste disposal is
underdeveloped.
Implementing the EU policy can increase plastic recycling and profitability for
plastic recycling businesses (Milios et al., 2018). Milios, Christensen, et al. (2018) used
the theoretical framework of the EU policy for plastic waste management and the circular
economy model for their sustainability impact assessment of increased plastic recycling.
The target sample was plastic recycling actors in three countries Denmark, Sweden, and
23
Norway. Nakatani et al. (2017) presented a variability-based optimal design framework
for constructing a robust recycling system that considers external changes such as
fluctuations in material prices. Therefore, a circular economy in the EU policy and
variability-based optimal design are other frameworks for plastic recycling studies.
However, the framework was not suited to my study on plastic recycling in Nigeria
because plastic waste management policies in Nigeria are less developed than in the EU.
Also, the variability-based optimal design was not a suitable framework for my study
because plastic recycling statistics were not readily available in Nigeria.
The train-the-trainer model is an educational system where a resource person
trains students who get certified to train and certify other students (Cheung et al., 2017).
The more trainers train other students, the more there is growth in the knowledge of
plastic recycling. Also, it included a curriculum on plastic recycling in schools that
teaches students recycling behavior (Faisal et al., 2018; Kerscher, 2019). Cheung et al.
(2017) suggested that primary schools include the train-the-trainer plastic recycling
curriculum in their general study course to encourage students' plastic recycling behavior.
Implementing topical plastics at the primary and secondary levels of German schools can
strengthen sustainable development education (Kerscher, 2019). Faisal et al. (2018)
taught K-12 students entrepreneurship in plastic recycling in India. Applying the results
could empower these kids with a consciousness that plastic waste can make wealth. The
study provided strategies for teaching kids how to dispose of plastic responsibly and
make money from plastic recycling. Faisal et al. used a waste management information
model as the conceptual framework for this study. The focus of my research was not on
24
increasing knowledge of plastic recycling behavior in the citizenry. Thus, I did not use
any educational models, such as the train-the-trainer model, curriculum on plastic
recycling, or waste information model, in my research on the strategies business owners
use to improve the profitability of their plastic recycling business.
Business owners can use economic models as frameworks to determine the
profitability of a plastic recycling business, such as profit analysis models, breakeven
analysis, optimization models, and analysis of unit and production costs (Hassanpour,
2015; Rowe et al., 2017). Hassanpour (2015) studied the plastic waste recycling
industry's economic indices using a value-added percent theoretical framework of 62%.
The author also used the theories of profit, annual income, breakeven point, value-added,
output value, data value, the variable cost of a good unit, and production costs. The target
sample was small plastic recycling businesses in Tehran, Iran. Rowe et al. (2017) used
combined theoretical models of the manufacturer's profit formulation, sole-sourcing
optimization, and dual-sourcing optimization to study recycling procurement strategies
with variable yield suppliers. Using the sourcing optimization models, business owners
ensure that goods from one or two suppliers are at optimal market prices. The authors'
target sample was the expanded polystyrene (EPS) packaging industry in the United
States. In their research on the sustainability of small businesses, Warren and Szostek
(2017) used the conceptual framework of the triangulation of data from cash flow
statements and profit and loss statements. The target sample was eight small businesses in
the southeastern United States. I did not use economic models such as profit analysis,
25
breakeven analysis, sole-sourcing optimization, or dual-sourcing models because my
study was not on the economics of plastic recycling.
The focus of my study was not on the recycling of plastic products or on how the
populace can exhibit recycling behavior. Also, the focus of my study was not on how
recycled products could be more profitable. These product-oriented models did not give
insight into the strategies business managers of plastic recycling businesses use to
improve profitability. Thus, the product-oriented models were not suitable for my study.
Interpretive Models
The interpretive model involves understanding a problem and arriving at
solutions. Researchers can combine the interpretive model with other models to analyze
the identified problems (Kumar et al., 2019; Satapathy, 2017). The multiple-level
transition theory is a transition framework. However, the transition framework tries to
understand the problem in a sector and how it interacts with the stakeholders technically
and socially (Bilali, 2019; Oyake-Ombis et al., 2015). Therefore, I have grouped the
interpretive structural models and multiple-level transition theories into interpretive
models.
Interpretive structural modeling (ISM) is a method for identifying relations
between items that make up the problem (Kumar et al., 2019; Satapathy, 2017). The
process starts with identifying the variables related to the problem, which is the
interpretive stage. The next stage involves contextualizing meaningful subordinate
relationships and is the structural stage (Kumar et al., 2019; Satapathy, 2017). Once the
researcher establishes the contextual relation, they develop a structural self-interaction
26
matrix (SSIM) based on comparing pairwise variables (Kumar et al., 2019; Satapathy,
2017). The SSIM is the modeling stage. The ISM, therefore, interprets a problem and
analyzes the problem with supporting models such as SSIM to determine which problem
has the highest impact.
There are 23 barriers to plastic recycling in India, which Satapathy (2017) found
using an ISM framework. Satapathy (2017) combined the interpretive structural modeling
(ISM) with the structural self-integration matrix model (SSIM) and the impact matrix
cross-reference multiplication applied to a classification model (MICMAC) to arrive at
these 23 barriers to plastic recycling. Satapathy used the MICMAC to cluster the barriers
into categories to determine their relative driving and dependence powers. Consequently,
Satapathy determined the three most significant plastic recycling factors in India: (a) the
scarcity of plastic waste, (b) the use of additives, the amount of scrap, and (c) toxic gases.
The target sample of the study was from the plastic industry in India. I did not use the
interpretive structural model because the focus of my study was not to identify the
relations among challenges encountered by plastics recycling businesses to improve their
profitability.
The multiple-level perspective (MLP) is a transition framework. The MLP
transitions occur through processes interacting in and among the niche, socio-technical
regime, and socio-technical landscape levels (Bilali, 2019). The researcher can perform
analysis at any of these levels. Oyake-Ombis et al. (2015) used a conceptual framework
of multiple level perspective, a transition theory combined with a strategic niche
management model. Oyake-Ombis et al. found no government support and policies for all
27
innovation actors to harmonize plastic production and waste handling. The target sample
was the actors in Kenya's plastic waste management industry. Therefore, I did not use the
MLP theory because my study was not on the interaction of the plastic recycling
businesses with a niche market, socio-technical interaction with the existing regime, and
the national landscape.
My study did not aim to identify the plastic recycling industry's problem and
proffer solutions. Identifying the plastic recycling industry problems did not give me the
strategies that business owners of plastic recycling businesses use to improve
profitability. The interpretive models do not reveal the leadership styles of business
owners that can contribute to increased profitability. Hence, I did not use the interpretive
models for my study since they were more suitable for identifying problems and finding
solutions.
Impact of Plastic Recycling on Recycling Businesses
The market demand for recycled products impacts the profitability of small plastic
recycling businesses (Nakatani et al., 2017). The pricing of recycled products for small
plastic recycling businesses is also affected by the demand for recycled products
(Nakatani et al., 2017). Small plastic recycling businesses must have high enough
revenues to accommodate plastic recycling's additional processing efforts to be profitable
(Ragossnig & Schneider, 2017). Applying supply chain loop principles by small plastic
recycling businesses will attract additional investment and operational costs from reverse
logistics (Ren et al., 2020). Therefore, small plastic recycling businesses must consider
the demand for recycled products and plastic waste collection before designing the
28
recycling process for their plastic recycling business (Nakatani et al., 2017). When there
is an increasing demand for recycled products, and the level of plastic recycling is low,
small plastic recycling businesses will encounter a price increase for their recycled
products (Tansel, 2020). Plastic recycling businesses should align recycling and material
recovery with supply chain operations (Tansel, 2020). Consequently, the demand for
recycled products, plastic waste availability, and high production revenues impact plastic
recycling profitability.
Plastic recycling targets established in the EU Policy and a ban on exporting
recycled plastics gave rise to plastic recycling businesses experiencing increased profits
(Milios, Christensen, et al., 2018). Also, Milios, Christensen, et al. (2018) found that EU
plastic recycling targets, coupled with limited plastic waste exports, gave rise to average
revenues amongst plastic recycling businesses. Additionally, an increase in the amount of
generated plastics recycled leads to higher profitability for plastic recycling businesses
(Genc et al., 2019). Furthermore, Genc et al. (2019) found in Turkey that plastic
recycling can only be profitable if the recovery of plastics is improved. Developing
nations with cheap recycling costs may become manufacturing hubs concurrently with
countries such as China, resulting in more economical and convenient reusing of recycled
materials (Qu et al., 2019). Hence, policies, increased recycled waste, recovery of
plastics, and cheap recycling costs positively impact small recycling businesses.
Business leaders of a construction company in Brazil that applied reverse logistics
for solid waste management experienced increased profit (Neto & Correia, 2019). Neto
and Correia found that construction companies made over $450,000 annually while
29
recycling businesses made over $250,000 annually in Brazil. The implementation of e-
commerce strategies in small and medium-scale businesses positively impacted their
profitability (Alzahrani, 2019). Small plastic recycling businesses can also improve
profitability through an e-commerce strategy. Maghmoumi et al. (2020) stated that waste
managers need to institute a robust organizational vision, improving decision-making on
reverse logistics to result in sustainable solid waste management. Thus, e-commerce and
organizational vision to utilize reverse logistics positively impact the profitability of
small plastic recycling businesses.
Recycled plastic demand impacts plastic recycling businesses' profitability and
the price of resource materials such as plastic waste (Nakatani et al., 2017). Plastic
recyclers can optimally design a plastic recycling plant to accommodate the resource
price and demand, thereby creating maximum profits for the plastic recycling business
(Nakatani et al., 2017). Kehinde et al. (2020) stated that plastic recycling provides
employment opportunities in developing countries for numerous families, including
office jobs, to informal economic activities. Kehinde et al. also mentioned that plastic
recycling helps conserve nonrenewable resources, such as the nation's oil and gas
reserves. Ren et al. (2020) showed that maintaining relatively lower carbon volatility is
essential to industrial stakeholders' investment decision-making, the main long-term
participants in carbon markets, into low-carbon supply chains. Therefore, pricing and
demand for recycled products and a stable low oil price create higher profitability for
plastic recycling businesses, providing employment opportunities.
30
Gall et al. (2020) found that a high quality of plastic mechanical recycling was
achievable with the informal sector of waste pickers and brought some socio-economic
benefits. Using informal waste pickers brought about some socio-economic benefits,
demonstrating that they could source quality plastic waste, resulting in high-quality
plastic mechanical recycling (Gall et al., 2020). This quality plastic recycling provides
economic benefits, establishes trust, and develops a dependable supply-buyer relationship
with the waste pickers (Gall et al., 2020). An environmental tax can lead to higher
material recycling than countries with low environmental taxes and material recycling
rates (Nastase et al., 2019). Hence, informal waste pickers make a living through their
informal activity of picking, separating waste, and selling plastic waste to plastic
recyclers. Also, there is more material recycling in countries with environmental taxes.
Biorefinery makes the plant more profitable by optimizing inputs from other
processes (Satchatippavarn et al., 2016). The biorefining process converts plastic waste to
oil and promotes more recycling than other stand-alone recycling techniques
(Satchatippavarn et al., 2016). Dhanalakshmi (2019) reported that Ernakulam, India
generated 26.56 tons of plastic waste per day and could earn $57,491 per day by
producing brick tiles from plastic waste. Santander et al. (2020) used a closed-loop
supply chain model for a distributed plastic recycling network of 3D printers in France's
northeast. Santander et al. found that this approach leads to positive environmental and
economic benefits. Hence, small businesses adopting the principles of reuse and
recycling can make more profits. If the particle sizes of plastic waste fractions were
standardized, the preprocessors could minimize their transport costs, and recyclers could
31
avoid fine particles and shredder steps (Maisel et al., 2020). Kim and Jeong (2017) found
that refuse plastic fuel (RPF) has high associated transportation costs, requiring dedicated
boilers. RPF's treatment paths need to be simplified to reduce environmental costs (Kim
& Jeong, 2017). Consequently, improving the plastic recycling processes can reduce
overhead costs, translating to more profits.
Circular Economy Framework
A circular economy is an economic system where waste managers practice the
principles of reducing plastic waste by reusing, remaking, and recycling, thereby curbing
environmental pollution through plastic waste disposal and incineration (Ezeudu &
Ezeudu, 2019; Huang et al., 2020). Cheung et al. (2017) discussed the circular economy
principles using train-the-trainer techniques. The authors showed that students imbibing
the circular economy principles could positively impact plastic recycling behavior early.
Ezeudu and Ezeudu (2019) used circular economy techniques in waste management in
Nigeria to improve waste management businesses' working conditions. A circular
economy's philosophy is to maximize value by using a resource, reusing, and
regenerating the material at the end of service life (Mrowiec, 2018). Ezeudu and Ezeudu
also applied the circular economy in Nigeria's waste management sector to improve
workers' safety and increase waste recovery. The increased closed-loop recycling of PET
bottles in the United States resulted in environmental benefits from a product-level
assessment basis (Lonca et al., 2020). Hence, education on circular economy develops
recycling behavior. Also, waste managers apply a circular economy to achieve workers'
safety and to gain environmental benefits in the waste management sector.
32
Students' education in primary and secondary schools in Germany helped align
the plastic recycling behavior of students to the circular economy's aspirations in the EU
policy (Kerscher, 2019). Furthermore, Kerscher (2019) showed that plastic recycling
behavior in EU countries like Germany would lead to sustainable development in the
EU's plastic recycling businesses. As a country transitioning to a circular economy, the
focus should be on reducing impurities and losses through product innovation,
technology improvement, and focused plastic waste management (Eriksen et al., 2019).
Therefore, the circular economy model aligns with plastic recycling goals of reuse and
reduction in carbon footprint.
Lower carbon price facilitates decision-making in reverse logistics (Ren et al.,
2020). A sound market condition could result in an optimal balance that encourages a
closed-loop supply chain without putting additional burdens on plastic recycling
businesses (Ren et al., 2020). Horvath et al. (2018), in their study on business solutions
for transitions to a circular economy, found that the linear application of circular
economy in developed nations does not apply in its entirety to developing countries.
Business solutions, such as the business model canvas, provide a holistic business
solution to sustainability in Kenya's circular economy (Horvath et al., 2018). Horvath et
al. (2018) considered plastic recycling a low priority in implementing a circular economy
because it does not provide complete material recovery. A circular economy can reduce
carbon footprint and is sustainable when combined with business solutions. However, the
linear application of circular economy in developed nations does not apply in developing
countries.
33
An estimated 3.6 million tons of CO
2
eq was generated from 2.7 million tons of
plastic waste by incineration in 2017 in South Korea (Jang et al., 2020). Jang et al. (2020)
found that South Korea could avoid approximately 6.6 million tons of CO
2
eq gaseous
emission to the environment through material recycling. South Korea is engaging in
discussions to better recycle plastic packaging with a circular economy aspiration (Jang et
al., 2020). The recycling process is material, energy, and emission-intensive compared to
the supply of virgin material (Lonca et al., 2020). Consequently, using a circular
economy leads to fewer carbon emissions and better energy optimization, bringing about
higher profits for plastic recycling businesses.
The circular framework involves using and disposing of legacy additives in
plastic waste. Legacy additives are heavy metals such as lead and cadmium, which the
European Chemical Agency (ECHA) discontinued in producing PVC. Hence the old
stock of recycled PVC contains legacy additives. The use of legacy additives and their
disposal in plastic recycling poses several issues that the ECHA addresses in regulating
the disposal of legacy additives in plastic waste (Wagner & Schlummer, 2020).
According to environmental regulations, legacy additives are disposed of because of their
toxic nature and stipulated regulatory levels in plastic wastes with legacy additives
(Wagner & Schlummer, 2020). The environmentally sensitive nature of plastic waste
containing legacy additives means that they are tricky to dispose of and are complex to
segregate for plastic recycling. Therefore, a circular framework for legacy additives in
plastic waste is difficult to implement and is challenging for developing nations with
weak plastic recycling policies.
34
The European Commission (EC), on December 2, 2015, adopted a circular
economy framework that involves a roadmap for new legislation on waste management
in the EC toward a circular economy (Mrowiec, 2018). The recycling rates approved by
the European Commission (EC) are a minimum of 50% up to 2025 and 55% till 2030
(Mrowiec, 2018). Baran (2020) stated that EU countries apply their circular economy
strategy for environmental and economic benefits. Hence, the EU circular economy
policy on plastic recycling engenders more profitability for plastic recycling businesses.
In the EU, plastic waste management's efficiency improved between 2006 and
2016 (Baran, 2020). Additionally, the amount of plastic waste collected for recycling
increased by 79.0%, energy recovery by 61.0%, and landfill waste decreased by 43.0%
(Baran, 2020). Market conditions' stability is necessary for recycled plastics and enables
recyclers to invest in capacities and new technology (Baran, 2020). Baran (2020) stated
that a comprehensive regulatory framework would drive accountability and transparency
in the data collection of recycling rates and their calculation. Furthermore, Kerdlap et al.
(2020) found that for a small distributed recycling system compared to large centralized
recycling systems, the life cycle and greenhouse gas emissions are sensitive to the
distance traveled by waste trucks and the trucks' size. Thus, stable market conditions, a
comprehensive regulatory framework, and distributed recycling systems can improve
plastic waste management efficiency.
The circular economy principles consist of three main ambitions: (a) achieve a
robust after-use plastic economy where recycling, reuse, and focused biodegradation
thrive; (b) significantly arrest leaks of plastic waste into the natural systems such as the
35
ocean, landfills, and the environment in general, and (c) separate plastics from fossil
feedstocks by addressing cycle losses, through material transformation, option
consideration for renewable sourced feedstocks (Mrowiec, 2018). Rhodes (2018) stated
that due to the high population around urban centers, there is a need to utilize an
integrated system such as the circular economy and permaculture in current urban
infrastructure design. In South Korea, the plastic recycling industry must implement
strategies and prioritize plastic packaging to transform the linear economy into a circular
economy (Jang et al., 2020). Consequently, the circular economy principles encourage
recycling, reusing, strategies for disposal of plastic packaging, and reducing
environmental plastic waste pollution.
Generated Plastic Waste
There is a supply chain shortage of plastic waste in some regions for plastic
recycling businesses (Satapathy, 2017). Due to the supply shortage for plastic waste,
waste managers should pay attention to the supply chain for plastic waste, such as
suppliers of plastic waste and people that generate plastic waste. The percentage of
generated waste that is recycled is low (Geyer et al., 2017). In 2015, the plastic waste
generated was approximately 6300 million tons (Mt), and globally recyclers recycled 9%
of the amount (Geyer et al., 2017). Rhodes (2018) stated that China, Indonesia, the
Philippines, Vietnam, and Sri Lanka as the heaviest plastic polluters contributing 56% of
the global plastic waste. Plastic recyclers need to increase the volume of recycled plastic
waste, and there is a shortage of quality plastic waste for plastic recycling businesses.
36
Furthermore, the public awareness campaign can positively impact plastic
recycling in developing countries (Oyake-Ombis et al., 2015). Statistics show the need to
improve generated waste recycled in developing countries (Babayemi et al., 2018; Geyer
et al., 2017). Babayemi et al. (2018) presented that the total volume of imported plastic,
newly produced plastic, and plastic components going into the Nigerian technosphere
from 1996 to 2014 was 23,400,000 tons. The authors also stated that only 12% of this
amount of plastics entered the recycling stream in the Nigerian technosphere. Zhang et al.
(2020) found that the annual growth of GDP per capita in the past 5 years is an important
influencing factor of food waste on the university campus, whether a low-income or a
higher-income country. Governments in developing countries should create more public
awareness on recycling generated waste through media and regulations.
The ban by the Chinese government in January 2018 on the importation of plastic
waste has a global impact on globally generated waste plastic (Huang et al., 2020). Due
to this new Chinese policy, globally exported plastic waste to China will displace an
estimated 111 million metric tons of plastic waste by 2030 (Brooks et al., 2018). The
Chinese government's import ban has necessitated other economies' need to increase their
waste treatment capacity and increase local plastic waste recycling (Huang et al., 2020).
Olusunmade et al. (2019) calculated plastic waste's energy potential in Nigeria and
recommended that waste recyclers treat plastic waste as a resource. Olusunmade et al.
also concluded that plastic recycling businesses should use thermo-chemical approaches
to recover plastic waste. Developing nations need to increase the quantity of plastic waste
recycled and approach plastic waste recycling as a profitable business venture.
37
Gabriel et al. (2018) concluded that the popular use of material value conservation
design in plastic packaging saves manufacturers from consuming virgin plastic.
Ultimately, this reduces the plastic waste generated in the plastic packaging industry and
leads to higher quality plastic waste for the recycling industry (Gabriel et al., 2018).
Therefore, material value conservation design can positively impact the waste generated
from plastic packaging by reducing the volume generated and improving plastic waste
quality.
Plastic Waste Segregation
Cheung et al. (2018) found that plastic recycling bins (PRB) and posters helped
improve recycling behavior. People will segregate their waste in recycling bins because
recycling behavior has helped shape their plastic disposal actions. Cioca et al. (2018)
found out that a mechanical separation facility (MRF) is more advantageous because they
bring about more economic benefits by reducing operating costs and improving return on
investment (ROI). Lebreton and Andrady (2019) showed that plastic waste growth could
reduce when developing countries build waste management infrastructures. In 84
recovery scenarios, Eriksen et al. (2019) found that a higher recovery rate could be
achieved with increased source segregation and MRF efficiencies to about 17% out of
100% plastic waste. The authors also show that reducing plastic waste growth can happen
if developing countries reduce plastic waste in their municipal solid waste. Hence, plastic
waste segregation helps the plastic recycling process and creates a plastic recycling
culture.
38
Using automated plastic waste segregation systems can improve the efficiency of
the sorting system for plastic recycling businesses, which can translate to improved
business profitability. Tarun et al. (2019) presented their research on convolutional neural
networks (CNN), which sorts waste materials into plastic and nonplastic. CNN is an
efficient machine learning technique that maximizes learning efficiency (Tarun et al.,
2019). Such a sorting system can reduce the associated costs of sorting plastic and non-
plastic material and the human effort required at this stage of the plastic recycling
process. The implication is that automatic sorting systems are essential in improving the
profitability of plastic recycling businesses. Subin et al. (2015) presented another
technique applicable to plastic waste segregation: the gray level co-occurrence matrix
(GLCM). The GLGM technique is applied to a robotic arm to improve efficiency by
bringing about an automated sorting system (Subin et al., 2015). Therefore, plastic
recycling businesses' automated waste segregation systems contribute to their
profitability. However, the cost of utilizing such a computerized sorting system may not
be affordable for small and medium enterprises.
The segregation of plastic waste with toxic substances represents another
challenge for waste disposal. The United Nations Industrial Development Organization
(UNIDO) discussed the segregation of plastic components and e-wastes contaminated
with polybrominated diphenyl ethers ("Austria, Philippines," 2018). The integrated
recycling industry (IRI) was the company nominated by UNIDO to dispose of this waste
was the integrated recycling industry (IRI). IRI carries out a further sorting of e-wastes to
segregate poisonous polybrominated diphenyl ethers (PBDEs), which they dispose of in
39
cement kilns to prevent re-entry into the recycling stream ("Austria, Philippines," 2018).
Hence, toxic substances such as PBDEs in plastic e-waste impact the procedures for
segregation and cost implications.
A well-established and efficient waste-sorting system is instrumental in achieving
success with CO
2
reduction and preventing marine debris's harmful effects on ocean life
(Lin & Nakamura, 2019). Owojori et al. (2020) recommended using three or more color-
coded bins for recyclable, compostable, and trash at the academic and administrative
buildings to facilitate recycling and partnering with waste recyclers to collect recycled
waste. Zhang et al. (2020) found waste characterization to be an influencing factor of
recycling potential. Particle size between 10-20 mm increases the sorting efficiency and
recyclability of the plastic fractions and minimizes the losses to fine fractions (Maisel et
al., 2020). The sorting technologies such as the air table, the wet shaking table,
triboelectric sorting, magnetic, eddy current sorting, flotation, and centrifugal sorting are
applicable for small sizes. Thus, the waste manager can use an automatic waste
segregator system to improve plastic recycling rates.
Additionally, the automated waste segregator separates dry, wet, and metallic
plastic waste without needing personal attention, and it is a cost-effective management
system. (Mapari et al., 2020). The automated waste segregation system can be intelligent
by adopting artificial intelligence (AI), machine learning (MI), and the internet of things
(IoT) (Mapari et al., 2020). The segregation system consists of an inductive proximity
sensor, capacitive proximity sensor, and moisture sensor to sense the type of waste
40
(Mapari et al., 2020). Accordingly, systems and automation can significantly improve
plastic waste segregation capabilities and efficiencies.
Smart tools such as blockchain smart contracts, powered by multi-sensor data-
fusion algorithms using artificial intelligence, help efficiently segregate commingled
plastics (Chidepatil et al., 2020). Waste managers also use near-infrared laser sensors to
differentiate six types of waste plastics in plastic waste segregation (Chidepatil et al.,
2020). Using artificial intelligence and multi-sensors, the waste manager can reduce
uncertainties and allow efficient and intelligent waste segregation (Chidepatil et al.,
2020). Waste managers can reduce waste by separating and recycling waste (Xin et al.,
2020). The manufacturer can use recycled products to replace raw materials leading to an
overall reduction in energy consumption, equivalent to energy savings (Xin et al., 2020).
Therefore, technology application to plastic segregation improves plastic waste
management efficiency, increasing business profitability.
Plastic Recycling Policies
Policies enabling plastic recycling are lacking in some nations. Noorhan et al.
(2016) recommended for plastic recycling policy that will allow the industry to develop.
These two mentioned studies are coming more from developing nations with weak and
underdeveloped plastic recycling industries. The EU policies on plastic recycling enable
plastic recycling and a circular economy framework (Milios, Christensen, et al., 2018;
Milios et al., 2018). Khoo (2019) recommended that waste planning policies include
incentives to encourage environmentally responsible investments in innovative
technologies that offier the dual benefit of minimizing waste and, simultaneously,
41
satisfying the need for renewable fuels. Thus, the studies of the mentioned authors show
that developed nations focus more on plastic recycling technological innovations.
On the contrary, developing countries need enabling plastic recycling policies,
infrastructures, and strategic partnerships to encourage plastic recycling business leaders.
De Lucia and Pazienza (2019) found that plastic waste is dependent on the type of
generated waste plastic. For example, plastic packaging and plastic films suggest using
subsidies (De Lucia & Pazienza, 2019). Alternatively, De Lucia and Pazienza posited that
the types of plastic waste generated by cereal crop activities favor adopting a tax-credit
mechanism. Kodzhebash and Krivence (2018) identified reforms involving solutions to
an organization's economic structure, resource-saving managerial structure, and
environmental protection policy in Ukraine. Hence, developing nations need to develop
policies that target the different types of plastic waste streams, direct businesses to
recycle their plastic waste by restructuring, and reduce plastic waste production.
Some states in the United States have laws enabling single plastic use, such as
banning plastic bags (King, 2019). Similarly, these states in the United States also have
laws stipulating that plastic recycling centers' locations must be close to business centers
(King, 2019). The Chinese government's policy initiatives to close down the informal
sector plastic recycling sector in Wenan County, China, in 2011 due to environmental
pollution led to many plastic recycling industries going underground to operate in other
parts of China (Goldstein, 2017). An appropriate developed global policy framework will
enable the global community to reap the benefits of China's new policies for
environmental sustainability and social justice by mitigating unintended consequences
42
(Qu et al., 2019). Accordingly, plastic recycling policies will help standardize plastic
recycling globally and make plastic recycling more profitable.
Additionally, a superior approach would have been to formalize the informal
sector of plastic recycling businesses, which would have created an opportunity to
standardize business practices and processes (Goldstein, 2017). Actors in waste
management should view transportation as an integral part of logistics operations for an
excellent attitude to effective waste management policy in Ukraine (Kodzhebash &
Krivence, 2018). Therefore, plastic recycling policies impact plastic recycling by
dictating the type of plastics to use and the location of plastic recycling plants.
Waste management policymakers should put laws in place that allow the use of
plastic waste for electricity generation, using biorefinery recycling methods by
policymakers in Nigeria (Ayodele et al., 2020). Ayodele et al. (2020) stated that Nigeria
has the potential for electricity generation from plastic waste to about 87.5 megawatts.
Asari et al. (2019) recommended integrating policies to improve plastic waste collection
and recycling plastics in Samoa, a Pacific island country. Wang et al. (2020) discussed
that the ban on plastic waste imports would cause other developed countries to ban plastic
waste exports. Consequently, import bans from developed nations will drive developing
nations' plastics recycling industry's growth. Alternatively, the developing nations which
do not have strict waste management policies will become dumping grounds for solid
waste from developed countries (Qu et al., 2019). Thus, the policy ban on nations that
import plastic waste, such as China, impacts plastic recycling growth in developing
countries.
43
Policymakers have a critical role in formulating and implementing environmental
regulations and establishing a clean environment through national legislation (Khoo,
2019). Waste planning policies should have inbuilt incentives to encourage investments
targeted at environmental sustainability, yielding innovative technologies that achieve the
dual purpose of minimizing waste and meeting renewable fuels' needs (Khoo, 2019).
Consequently, waste management actors can view plastic recycling policies as catalysts
for developing plastic recycling, minimizing plastic waste generation, meeting renewable
fuel objectives, and establishing a clean environment.
Recycling Behavior
Plastic recycling education of the populace is another identified theme in the
literature review. Cheung et al. (2018) presented the positive impact on recycling
behavior, including a train-the-trainer plastic recycling curriculum in primary school.
Faisal et al. (2018) concluded that students could learn recycling behavior using training
strategies for K-12 students for plastic recycling entrepreneurship. Evinemi and Afon
(2016) recommended that there should be public enlightenment and environmental
awareness training for the populace. Additionally, Evinemi and Afon (2016)
recommended continuous enlightenment programs for all health institutions' managers
and waste management officers. Also, Owojori et al. (2020) recommended environmental
awareness to change staff and students' perceptions and attitudes towards environmental
sustainability in the university. Kerscher (2019) discussed the successful education of
primary and secondary schools in Germany on topical plastics waste. Accordingly,
44
educating the populace on plastic recycling results in the citizenry imbibing recycling
behavior as a necessary way of life.
There is no support for waste management in Romania's waste management
system (Nastase et al., 2019). Nastase et al. (2019) also discovered that waste operators
did not want to take the additional financial burden of separating waste because they did
not have any incentives. Nastase et al. found that the bins provided for waste separation
were insufficient. Mattoo et al. (2020) showed that for the disposal of biomedical waste
in Pakistan, continuous training or awareness programs were necessary for hospital
workers to safely handle and segregate biomedical waste. Therefore, developed and
developing countries should target waste managers with ongoing awareness programs,
especially in handling sensitive waste such as biomedical and hazardous waste.
Educational strategies are another way to foster plastic recycling behavior in
students. Schools can use strategies such as teaching students aged 9-12 about plastic
recycling during the school timetable during non-academic hours (So & Chow, 2019).
Some of these strategies involved showing plastic recycling videos during lunch hours
and training students to be trainers of other students (So & Chow, 2019). So & Chow
went further to include the parents of the students in plastic recycling projects and, by so
doing, created an awareness of plastic recycling among the parents. Cheung et al. (2018)
found that using plastic recycling bins and poster intervention changed university
students' recycling behavior on the participating campus. The positive impact of a
community's recycling behavior through these identified education strategies can improve
segregation and the level of generated plastic waste that is recycled (Tiew et al., 2019).
45
Hence, plastic recycling education should be part of the curriculum at all levels of the
education system in countries.
Plastic waste segregation at the source of plastic waste disposal is central to the
success of the plastic recycling process (Banks et al., 2020; Chow et al., 2016). Plastic
recycling quality is affected when all plastics are discarded into a single recycling bin,
increasing the plastic recycling business's cross contamination and operation cost (Chow
et al., 2016). Chow et al., 2016 engineered a new eight-compartment plastic waste bin to
facilitate plastic recycling and sorting at the source. Consequently, this provides
educators insight into problem-solving on the environmental issue concerning plastic
waste (Chow et al., 2016). Banks et al. (2020) found that universities can achieve a
66.7% diversion of plastic waste through better sorting at the waste bin, higher than the
current diversion rate of 48%. The National Institutes of Health (NIH) established the
green labs' program, promoting NIH laboratory personnel's awareness and participation
in sustainable laboratory practices (Banks et al., 2020). The program has an excellent
database of green-lab supplies and equipment and offers tips and tricks on greening your
lab (Banks et al., 2020). Thus, recycling education in countries must include knowledge
of the segregation of the different plastic waste streams and standardized plastic waste
sorting systems.
Monetary incentives and economic and environmental benefits can drive
recycling behavior. Households in Pakistan have good recycling attitudes; however,
monetary benefits drive their recycling behavior, environmental benefits, and recycling
opportunities (Abbasi & Sheikh, 2016). Furthermore, the authors discovered that social
46
norms and government initiatives do not drive households' recycling behavior (Abbasi &
Sheikh, 2016). Meng et al. (2019) discovered that the five most significant factors
affecting recycling behavior are publicity and education, accessibility to recycling
facilities, accessibility to classification facilities, willingness to participate in
classification, and residents' environmental awareness. Consequently, there may be some
relationship between an incentive system and recycling behavior. Also, public awareness
and education may be crucial to recycling behavior.
Challenges of Plastic Recycling
There are many barriers to the effective plastic recycling process. Satapathy
(2017) found most influential divers in these barriers to plastic recycling in India are the
amount of scrap, the use of additives, and toxic gas. The amount of scrap available is a
challenge because many plastic recycling businesses compete for the available plastic
waste that is properly segregated, washed, and ready for utilization by the plastic
recycling processes. Ahmed et al. (2018) presented an illustrative diagram of the
machines used for the different stages of plastic recycling, including cutters, crushers,
shredders, plastic segregating machines, and low-cost plastic recycling machines. As
well, the plastic recycling process can be mechanical or thermo-chemical. Additives
impact plastic recycling by changing the used plastic properties back to the original state.
Therefore, the amount of scrap, additives, and toxic gas can be a solid challenge to
effective plastic recycling.
The by-product of using additives is a toxic gas that represents health challenges
for workers and environmental safety disposal concerns. The health and safety of workers
47
who handle waste and recyclables are paramount, and waste management must develop
waste collection and recycling operations that guarantee workers' safety and health
(Ragossnig & Schneider, 2017). Hence, identified barriers in plastic recycling
significantly impact the profitability of a plastic recycling business (Satapathy, 2017).
The waste managers in plastic recycling need to consider product design, technical
equipment for processing plastic waste, social issues, organizational structure for plastic
recycling, and recycled products' marketability (Ragossnig & Schneider, 2017).
Accordingly, mitigating toxic gases arising from the plastic recycling process and using
additives and technical and managerial organization of plastic recycling businesses leads
to profitability.
Barriers to plastic recycling in the hospitality business need concerted focus from
waste managers because of the high volume of plastic waste generated (Ramirez &
George, 2019). Ramirez and George (2019) identified the barriers to plastic recycling in
the hospitality business as “perceived high capital costs, doubts of return on investments,
lack of time, require too much management, and limited interest/knowledge” (p. 11).
Conversely, Ramirez and George listed the motivators for plastic recycling in the United
States hospitality industry: “potential cost savings, increased market share and image,
improvement, acquiring competitive advantage, intrinsic motivation, and enhanced
employee morale” (p. 11). Actors in the plastic recycling sector must mitigate the barriers
to achieving EU plastic recycling targets (Baran, 2020). Therefore, barriers to plastic
recycling negatively impact profitability. Also, encouraging the motivators to plastic
recycling may positively impact the profitability of plastic recycling businesses.
48
There is also a need to increase the European capacity to sort and recycle facilities
to accommodate increased quantities of plastic waste (Baran, 2020). Schut (2017), in the
article on the challenges of recycling problem packages, found that recycling tiny, rigid
plastic bottles and containers is tricky. The reason is that these items are less than the 2-
inch square area for trommels found in the material recovery facility (MRF) sorting
machines (Schut, 2017). To address this problem, the sorting lines of established material
recovery facilities have deployed robots and artificial intelligence to identify these tiny
pods that pass through the sorting machines in the material recovery facility (Schut,
2017). Thus, increasing the plastic sorting and recycling facilities will increase the
amount of plastic waste recycled. The use of robotic arms and artificial intelligence
addresses the issues of small sizes of plastic waste bottles.
Recycling plastic labels made from polyvinyl chloride (PVC) is challenging
because recyclers cannot recycle plastic labels (Kristina et al., 2018). In 2018 in
Indonesia, only plastic bottle wastes made from high-density polyethylene (HDPE) and
polyethylene terephthalate (PET) were recycled (Kristina et al., 2018). The innovative
solution deployed in this case study was plastic labels as a fuel mixture for its incinerator
and oil heater in the recycling plant PT LJF in Indonesia (Kristina et al., 2018).
Colombijn (2020) discussed the informal sector of waste pickers' conditions, how they
produce wastewater from washing their plastic waste, and its environmental effects.
Hence, plastic waste streams such as PVC that are difficult to recycle can fuel recycling
plants, and waste managers must improve informal waste pickers' work conditions.
49
Additionally, plastic recyclers distance themselves from these informal waste
pickers and the negative social norm they represent. Still, they benefit from the low prices
these waste pickers offer for plastic waste bottles in Indonesia (Colombijn, 2020).
Finally, the author mentioned a complicated network of different recycling business
actors, and no person has complete control (Colombijn, 2020). Thus, actors in waste
management should formalize cooperation between plastic recyclers and informal waste
pickers.
The barriers to recycling in Nova Scotia, Canada, had to do with a lack of
enabling infrastructure to support recycling agricultural plastic waste (Muise et al., 2016).
The farmers were not ready to leave their core farming task to provide agricultural plastic
waste (APW) transportation from their farms to recycling facilities. The farmers were,
however, positively disposed of the recycling of APW. Muise et al. recommended that
the solution was for the farmers and stakeholders to jointly sponsor a means for
transportation and segregation of APW. Consequently, transporting plastic waste to
recycling businesses can increase farmers' plastic recycling.
The supply chain of plastic recycling will be of interest in this study to understand
how plastic recycling businesses get their waste plastics. In the study, I sought to
understand the suppliers of plastic waste to plastic recycling businesses and what
strategies to use to improve plastic waste collection for the plastic recycling business.
Satapathy (2017) identified the challenge with the supply chain of waste plastics in India
and various other challenges to plastic recycling, which indicate that strategies are needed
to overcome these barriers. Additionally of interest are the sales of recycled products and
50
strategies used by competing businesses in the plastic recycling sector. Also, new plastic
recycling businesses will impact profitability because plastic recycling businesses may be
competing for the same suppliers and buyers.
The waste management sector actors, such as waste pickers, scrap dealers, and
preprocessors, lack financial resources, and plastic molders do not have managerial
expertise (Abbasi & Sheikh, 2016). Subsequently, the informal sector of waste
management experiences high patronage by waste pickers and scrap dealers because it
does not require high investment or managerial expertise (Abbasi & Sheikh, 2016). Thus,
the informal sector in waste management exists because it does not need any expertise,
and actors do not need any investment to make money from supplying plastic waste to
plastic recycling businesses.
Business Strategies
On the strategies of small businesses for applying Industry 4.0, Müller (2019)
used the conceptual framework of Industry 4.0 and the business model canvas for his
research. The author used a target sample of 22 CEOs in the German industrial sector.
The author found that the use of Industry 4.0 in small and medium-scale businesses
impacts plastic recycling businesses more than the clients patronizing the services of the
plastic recycling business. However, the plastic recycling business finds integrating
Industry 4.0 in its plastic recycling process challenging (Müller, 2019). Turner and
Endres (2017) used the conceptual framework of systems theory, chaos theory, and
complexity theory to study small businesses' business success rates focusing on three
coffee shops in Duval County, Florida. Turner and Endres found that networking,
51
effective business plans, and market differentiation strategies contribute to business
success. Hence, business leaders can utilize such business strategies to achieve business
success.
For business sustainability, a business leader must build customer relationships,
find, and follow his passions (Warren & Szostek, 2017). Also, employing sound financial
management and enhancing business knowledge impacts businesses' sustainability
(Warren & Szostek, 2017). Zwane et al. (2019) showed that planning, leading, and
organizing activities shaped new small restaurants' organizational architecture that
survived the first five years of operating in Durban, South Africa. The authors discussed
that staff's multiskilling helped the business be resilient to operational and customer
changes. Zwane et al. (2019) also mentioned that business managers used ambidextrous
leadership with their employees, hiring them for desired values and using them for
specific goals. Therefore, small businesses can remain sustainable and profitable by
business owners using relationship management with customers, practicing sound
financial management, structuring the business, and applying ambidextrous leadership
with multiskilled staff.
Gerig (2018) concluded that implementing business strategies in plastic recycling
contributes to business success, sustainability, and profitability. The author found that
small business organizations (SBOs) in the participating mortgage organizations
succeeded by effectively using continuing education and training, communication and
networking, and setting goals and planning. Kerdlap et al. (2020) recommended that
preprocessors and recyclers should improve communication between the end-of-life
52
actors. The plastic recycling business can benefit from strategic partnerships (Ahmed et
al., 2018). The percentage of generated waste recycled is low at 9% (Evinemi & Afon,
2016; Geyer et al., 2017). Subsequently, business leaders should undertake public
awareness campaigns on plastic recycling in developing nations. Accordingly, there is a
need to improve the recycling business's profitability by increasing the percentage of
generated waste recycled in developing nations through business strategies.
Automation in plastic recycling is desirable, and it can improve efficiency
substantially. Automation also allows for innovation since waste managers can program
plastic recycling processes to produce various recycled plastic. Automation enables
mechanical separators, cutters, washers, and shredders (see Ahmed et al., 2018; Cioca et
al., 2018; Nascimento et al., 2019). The safety levels in automated industries are higher,
and the production rates are more efficient. However, automation as a business strategy is
not prevalent in developing nations like Nigeria because of the constant energy challenge
(Nnaji, 2015). Thus, automation as a strategy is desirable. Still, depending on the world's
region, automation could be challenging to implement because of the burden of machine
maintenance, spare parts, and constant energy challenges.
Waste managers must consider some crucial factors regarding recovering and
recycling plastic waste. Mwanza et al. (2018) discovered the strategy for recovering and
recycling plastic solid waste, the essential considerations for the plastic manufacturer and
recyclers of plastic solid waste in Zambia. The most important factors are listed as
follows: (a) ensuring material applicability in manufacturing processes, (b) the cost of
acceptable alternative forms of disposal compared to recycling, (c) creating closer
53
engagements of recyclers with one another along the supply chain, (d) efficiency of the
municipality, private waste contractors or informal waste collectors in waste collection,
and (e) enforcement of producer responsibility regulations to encourage the collection of
plastic wastes (Mwanza et al., 2018). Consequently, waste managers can extend these
same principles to other developing nations for a successful plastic waste recycling
process that positively impacts business profitability.
Three critical success factors exist for the reusable plastic packaging (RPP)
system: top management commitment, lean support, and optimized inventory
management (Gardas et al., 2019). As such, the organizational structures in the waste
management sector and the interrelationships between the waste management and the
production sectors also affect the level of plastic recycling achieved (Ragossnig &
Schneider, 2017). Hence, organizational structure, leadership, and effective relationships
between waste managers and the production sector are essential for successful plastic
recycling businesses.
Alternatives to Plastic Recycling
There are other alternatives to plastic recycling, which I explore in the subsequent
review. Rujnić-Sokele and Pilipović (2017) examined the use of biodegradable plastics as
an alternative to plastic recycling. Biodegradable plastics are alternatives for use in areas
with high plastic waste, such as catering (Rujnić-Sokele & Pilipović, 2017).
Biodegradable plastics consist of compostable materials made from starch material.
However, they are cost-intensive, and the global production of biodegradable plastics is
low. Wei and Zimmermann (2017) proposed an alternative to plastic recycling by using
54
different identified enzymes to degrade plastic or change its molecular structure. Thus,
the other options for plastic recycling are biodegradable plastics and enzymes that can
degrade plastic waste.
Bioplastics can be categorized into three groups: "(a) bio-based or partially bio-
based materials, such as polyethylene (PE), polypropylene (PP), or polyethylene
terephthalate (PET) and bio-based technical performance polymers, such as poly
trimethylene terephthalate (PTT) or thermoplastic polyester elastomers (TPC-ET), which
are non-biodegradable plastics; (b) plastics that are simultaneously bio-based and
biodegradable, such as polylactic acid (PLA), polyhydroxyalkanoates (PHA) or
polybutylene succinate (PBS), starch and starch blends; and (c) fossil-based plastics that
are biodegradable, such as polybutylene adipate terephthalate (PBAT)” (Paço et al., 2019,
p. 415). Another category of plastics is oxo-biodegradable plastics, which is controversial
(Rhodes, 2018). The controversy surrounding oxo-biodegradable plastics is that it does
not biodegrade completely (Rhodes, 2018). It disintegrates into microplastic fragments
harmful to the environment, especially marine life, like petroleum-based plastics
(Rhodes, 2018). Therefore, there are different types of bioplastics; some are
biodegradable, others are partially biodegradable, and oxo-biodegradable plastic
disintegrates into microplastics harmful to marine life.
The incineration of plastic waste is another alternative to plastic recycling.
However, incineration contributes to carbon emissions and attracts an increasing
incineration cost in Antwerp, Belgium (De Weerdt et al., 2020). Dumping plastic waste
in landfills is a cheaper option for plastic recycling, but it adds to environmental pollution
55
(Avolio et al., 2019). Chen et al. (2019) found that automotive shredder residue
incineration causes the highest environmental burden versus benefit in terms of the
impact on human toxicity potential. The chemical recycling substituting purified
terephthalic acid (PTA) and ethylene glycol leads to a lower environmental impact per 1
tonne of PET waste (Rickert et al., 2020). However, this option has the challenge of
managing the toxic discharge from the chemicals. Waste managers in Belgium encourage
plastic recycling by taxing incineration, reducing incineration, and growth of plastic
waste (De Weerdt et al., 2020). Therefore, mechanical plastic recycling is a better option
when compared to all other alternatives of incineration and chemical recycling of plastic
waste.
Waste managers use microbial enzymes to degrade plastic waste, but managing
by-product disposal is challenging. Austin et al. (2018) showed that the bacteria ideonella
sakaiensis 201-F6 exhibited the rare ability to grow on PET as a significant carbon and
energy source. Paço et al. (2019) identified mucor rouxii as having viable biological
agents for plastics' biodegradation. However, the biodegradation of PET by these bacteria
produces a by-product called PETase. Austin et al. (2018) showed PETase degrades
another semi-aromatic polyester, polyethylene-2,5-furandicarboxylate (PEF). PEF is an
emerging bioderived PET replacement with improved barrier properties. The findings
show that the areas for further research are protein engineering to increase the
performance of PETase and develop its biodegrading properties of synthetic polymers.
Samrak et al. (2020) posited that bioengineering strategies could reduce the crystallinity
issues associated with PET waste and cause PET hydrolyzing enzymes' operating
56
temperatures to increase in the EU. Samrak et al. discussed the progress of enzyme
bioengineering research for new PET biocatalysts. Samrak et al. also explained the
current mechanisms for degrading plastics using enzymes. Hence, researchers are
currently perfecting the biodegradation of plastics using enzymes and bioengineering
enzymes to address crystallinity issues.
Waste managers use plastic waste for manufacturing products such as flood
barriers, roof tiles, block tiles, and road construction. Ondruska et al. (2017) used
recycled plastic waste to construct flood barriers. The authors then pressure-tested the
constructed flood barriers to certify their use as replacements for existing flood barriers.
The plastic flood barriers are from recycled waste polypropylene (PP) and polyethylene
(PE) plastics (Ondruska et al., 2017). The challenge with these newly constructed flood
barriers, which are ready for mass production in the Slovak Republic, is the price to
stamp the recycled waste plastics on the flood barriers, a mixture of recycled plastic and
metal (Ondruska et al., 2017). Ondruska et al. are confident that the unit price will be
competitive. The use of propylene diene monomer (EPDM) as a compatibilizer in the
blend of polypropylene (PP) and polyethylene (PE) leads to the improvement of the
chemical and mechanical properties of the mixed blend used in extruder injection
molding for recycled products (Hanna, 2019). Kaliyavaradhan et al. (2019) discovered
that the proper mix design adjustment to accommodate waste materials could produce
sustainable controlled low-strength material (CLSM) with acceptable plastic properties.
Therefore, researchers identified many alternative uses of plastic waste in different
industries, but what is not clear is if these options are commercially viable.
57
However, plastic waste used in the manufacture of Greentile, a slanted green roof
type, and plastic waste used to power recycling plants is commercially viable.
Furthermore, Ragaert et al. (2020) discovered they could use a sink fraction plastic waste
stream to manufacture Greentile for slanted green roofs. To achieve this, the authors
treated the plastic waste stream to remove the PVC and non-ferrous metal. Usually,
plastic recyclers incinerate the PVC from plastic waste streams because plastic recycling
plants cannot recycle PVC. Kristina et al. (2018) dealt with this similar challenge of what
to do with the PVC plastic waste stream by including the PVC plastic label as fuel for the
plastic recycling plant PT LJF in Indonesia. Ragaert et al. used a recycling approach to
bring a complex plastic waste stream from incineration to recycling. Nagy and Kuti
(2016) discussed the harm of incineration or energy recovery of plastic waste and its
harm to the environment. Thus, the identified alternative for plastic waste streams, such
as the Greentile roofs, is commercially viable. Still, the plastic waste stream treatment of
PVC and non-ferrous metals could create another waste disposal challenge. Also, PVC
waste as a fuel in the recycling plants creates environmental emission concerns.
Incinerated plastic waste creates environmental concerns, and waste managers
must be innovative in addressing these concerns (Nagy & Kuti, 2016). One way to
address emissions from incineration is through monitoring and control (Nagy & Kuti,
2016). Nagy and Kuti (2016) further explained incineration's human and environmental
risks. Chen et al. (2019) found that incineration of automotive shredder residues was the
main contributing factor, accounting for 79% of the total contribution of recovered
energy's environmental impact. Also, aluminum and plastic recycling contribute the most
58
to abiotic depletion and photochemical ozone creation potentials (Chen et al., 2019).
Incinerated ashes of solid fuels and municipal household waste contain heavy metals
(Horák et al., 2019). Khatib et al. (2019) researched using a certain amount of plastic
waste in reinforced concrete without compromising its strength. The combination of
gases emitting from waste incineration to generate electricity and recycling recyclables
results in greater GHG emission benefits than the volume of emissions from not combing
the two processes (Xin et al., 2020). Therefore, waste managers can apply innovations to
counter the harmful emissions from incinerating plastic waste. Waste managers must also
find safe ways to dispose of the heavy metals in incinerated plastic waste ash.
The different techniques for transforming waste plastics into oils are
thermochemical treatment/thermal cracking/pyrolysis, hydrocracking/hydrogenation, and
catalytic degradation/catalytic pyrolysis (Sikdar et al., 2020). Waste managers can use the
pyrolysis process on plastic waste containing polyethylene (PET) to produce 1-olefins
and n-paraffins (Sikdar et al., 2020). The products of this process contain heavy metals
and need further treatment. Sikdar et al. (2020) then subjected the heavy fraction
hydrocarbon to hydrotreating conditions using a hydrotreating catalyst. Sikdar et al.
converted heavy fraction hydrocarbon into a high viscosity indexed lubricating oil
composition using a dewaxing isomerization catalyst. Sikdar et al. found that waste
plastic-based pyrolyzed oils mitigate plastic pollution and use petroleum products. Hence,
waste managers can use many chemical processes to transform waste plastics into oils.
Thermal conversion is another technology that the system user can implement in
the existing system to convert waste into chemicals, fertilizers, oils, and other useful
59
products (Mapari et al., 2020). Consequently, researchers identified chemical options for
plastic recycling, such as converting plastic waste by thermal, hydro, and catalytic
processes to oils, are viable options with inherent chemical complexities. Waste
managers can use the products of these chemical processes for lubricating oils and in
agriculture.
Bioplastics are a suitable replacement for conventional plastics because they do
not negatively impact the environment due to their biodegradability (Gardas et al., 2019).
Bioplastic sources are renewable biomass sources such as vegetable oil, pea, and corn
starch (Gardas et al., 2019). Bioplastics are reusable and adaptable, have no carbon
footprint, GHG emission is 30% less than conventional plastics, and manufacturers use
them to construct shipping containers, reducing damages (Gardas et al., 2019). However,
bioplastics are not cheap to produce, so they cannot replace conventional plastics until a
technological breakthrough can reduce production costs.
Faraca et al. (2019) discovered that advanced mechanical recycling provided the
most considerable savings in the highest number of impact categories, including global
warming potential, compared to simple mechanical recycling and resulted in the lowest
total costs (negative costs). Furthermore, the authors demonstrated that a high quality of
recycled plastic leads to environmental savings and profit (Faraca et al., 2019). Lotfian et
al. (2019) found that waste managers can reduce the injection rate of coal, a reducing
agent, to use plastic materials as a substitution in metallurgical processes. Therefore,
advancements in science have improved mechanical recycling to lower recycling costs
60
and discovered alternative uses of waste from electrical and electronic equipment in
metallurgical processes.
Analysis of Plastic Recycling Themes
One area for research is the business strategy aspect of plastic recycling, for
which peer-reviewed journals are not readily available. My literature review's limitations
in the research studies are the sample sizes and possibly funding limitations restricting
their research's reach and extent. The different regions' needs vary depending on income
bracket, GDP per capita, disposal income, and government initiatives in plastic recycling.
Business leaders generally have a supply chain challenge of sourcing used plastic for
their plastic recycling business (see Milios, Christensen, et al., 2018; Satapathy, 2017).
Moreover, there is an added cost of waste collection cost that is part of plastic recycling
businesses' operating costs. Hence, I explored the business strategy aspect of plastic
recycling businesses in Nigeria because of an existing research study gap.
Additionally, businesses must have optimal plastic recycling levels to be
profitable. Local, regional, and global challenges to plastic recycling deter plastic
recycling businesses from optimal levels. The regions covered in my literature review for
plastic recycling include India, Peru, Iran, Pakistan, Indonesia, Europe, the United States
of America, Kenya, the United Kingdom, Croatia, Brazil, Nigeria, the Asia Pacific, and
the Pacific island country. So there is a focus on developing nations and overcoming
these countries' challenges to increase plastic recycling levels through recycling
businesses. A critical look at these regions shows us that developed nations have
overcome most of the challenges facing developing nations. For example, the focus in
61
developed countries is on automating the plastic recycling business to maximize
efficiency (Nascimento et al., 2019; Milios, Christensen, et al., 2018; Satapathy, 2017;
Torres & Cornejo, 2016). Thus, optimal plastic recycling levels increase profitability for
plastic recycling businesses.
Accordingly, my research question is, what strategies do small business managers
use to improve profitability in the plastic recycling industry? Thus, my business problem
will require rich data from small and medium-scale plastic recycling businesses. Yee et
al. (2017) used qualitative research in their study on patient safety using ICTs. Similarly,
I used the qualitative research methodology. Saunders et al. (2019) recommended
qualitative research when the researcher is interested in rich data from study participants.
Subsequently, I chose a multicase study because it suits my business problem, allowing
me to explore business strategies, reach data saturation, and use data triangulation.
Hence, my chosen research and interview questions helped me discover business
strategies in Nigeria's plastic recycling industry.
The alternatives to plastic recycling are useful to examine. In the literature review,
we have presented alternatives to plastic recycling such as the use of biodegradable
plastic, biorefinery of plastic wasted in oil fuel, conversion of plastic waste to electrical
energy, conversion of plastic waste into flood barriers by stamping the plastic waste on a
metal form, conversion of plastic waste into plastic brick tiles of green roof tiles, use of
plastic waste in pillars to increase their textile strength, use of plastic waste in road
construction and the use of PVC to fuel a plastic recycling plant (see Austin et al., 2018;
Khatib et al., 2019; Kristina et al., 2018; Ondruska et al., 2017; Rujnić-Sokele &
62
Pilipović, 2017; Satchatippavarn et al., 2016; Wei & Zimmermann, 2017). A further look
at these alternatives reveals that they are expensive and not sustainable for the use of
small and medium businesses. However, the listed alternatives to plastic recycling
provide a more environmentally friendly solution than incinerating plastic waste without
controlled emission and dumping plastic waste in landfills (Avolio et al., 2019; Nagy &
Kuti, 2016). Therefore, considering an alternative to plastic recycling is the cost factor
versus the environmental benefits.
Furthermore, there are some differences between mechanical and chemical plastic
recycling. Mechanical plastic recycling undergoes the typical processes of separating,
washing, drying, shredding, re-granulating, and compounding (Ahmed et al., 2018). The
chemical plastic recycling processes are not alike, but the types of chemical plastic
recycling are purification, decomposition, and conversion. The mechanical recycling
process uses additives for certain types of plastic, and the toxic gaseous emission has
safety concerns for workers. Chemical plastic recycling relies more on chemicals, so
chemical by-product disposal represents environmental concerns (Jiang et al., 2020).
Chemical plastic recycling is more hazardous, and recycling businesses using chemicals
must have a high safety standard. In contrast, chemical plastic recycling is more suitable
for a certain type of plastic but may not be commercially viable for some chemical
recycling types (Jiang et al., 2020). Hence, mechanical and chemical plastic recycling is
feasible for plastic recycling, but the waste manager must consider the ideal recycling
method for different plastic waste streams.
63
Consequently, the conceptual framework of the study is transformational
leadership, which researchers use to determine how a leader's idealized influence,
intellectual stimulation of followers, inspirational motivation, and individual
consideration of employees will lead to an increased level of profitability of plastic
recycling businesses (Boukamcha, 2019; Mahdikhani & Yazdani, 2020; Roibu et al.,
2019; Tănase, 2020). The premise is that business leaders who use transformational
leadership can bring about their business's profitability by inspiring employees to
innovate and cultivate a sense of business ownership (McManus, 2019). Accordingly,
transformational leadership as the lens of the study can help me discover the strategies
that business owners of plastic recycling businesses use to improve profitability.
Lastly, the plastic recycling research topic has a social change significance. The
improved plastic recycling level of the plastic recycling industry addresses the growing
problem of plastic environmental pollution. This industry also employs the community
through the value-added chain created by plastic recycling businesses (Milios,
Christensen, et al., 2018). The community enjoys the benefits of employment
opportunities through waste segregation and collection. Likewise, job opportunities for
hired hands and technicians increase as businesses increase plastic recycling levels
(Satapathy, 2017). Therefore, improving the profitability of plastic recycling businesses
is a win-win for social change impact.
The main driver for any research topic should be its contribution to social change
(Schirmer et al., 2016). Subsequently, improving the profitability of plastic recycling
businesses increases their financial well-being, which raises their sphere of influence.
64
The organization can give back to society because they have additional finance from its
annual profit (Yuan et al., 2020). The plastic recycling businesses must ensure that they
do not pollute the environment and carry out corporate social responsibility to
communities located in their operational areas. Ensuring that our environment is not
polluted and remains sustainable is also a social change driver because waste managers
must conserve environmental resources in such a manner as to transfer wealth to the next
generation. Therefore, it will be challenging for a plastic recycling business to render
social responsibility if it is not doing well financially, so increasing the profitability of
plastic recycling businesses is vital to social change and social responsibility.
Transition
The objective of this study was to understand the strategies small business
managers in the plastic recycling industry use to improve profitability. In Section 1, I
explored the following issues: background of the problem, problem statement, purpose
statement, nature of the study, the research question and interview questions, the
conceptual framework, and literature review.
Section 2 contains the discussion on the role of the researcher, the research
method, the research design, the population and sampling, data collection instruments,
the data analysis, and the reliability and validity of the study. In Section 3, I discussed the
presentation of the study’s findings, professional applications, implications for social
change, and recommendations for future studies.
65
Section 2: The Project
I used a qualitative multiple case study to explore the strategies that small plastic
recycling business managers used to improve the profitability of their business in
Southwest Nigeria. In this section, I discuss the purpose of the study, my role as a
researcher, the participants, and the research method and design. Additionally, my
discussion includes ethical concerns, the data collection process, and the study’s
reliability and validity.
Purpose Statement
The purpose of this qualitative multiple case study was to explore strategies small
business managers in plastic recycling businesses use to improve profitability. The target
population comprises nine business owners from nine small plastic recycling businesses
in the Lagos state of Nigeria who implemented strategies to improve their business
profitability. The implication for positive social change includes the potential to improve
the business practices of plastic recycling businesses in Nigeria. Consequently, improving
business practices should positively impact profitability, expand existing businesses, and
lead to more job opportunities. Likewise, increased profitability creates more wealth for
the plastic recycling businesses to contribute to society through community projects,
sponsorship for social entrepreneurship programs, and the potential to support
educational scholarship programs in the businesses' communities.
Role of the Researcher
The role of the researcher includes collecting data, analyzing the data, selecting
the appropriate research method, and designing and managing the research process to
66
inculcate ethical considerations and eliminate personal bias to the barest minimum
(Hargis, 2020). As a researcher, my role was to develop an interview guide, find and
establish contact with interviewees, get their informed consent, conduct an interview with
the participant and record the interviews with reliable recording devices. Furthermore,
my role as a researcher was transcribing recorded interviews, identifying the different
themes from my data collection, analyzing the results with Nvivo software, and
presenting my findings.
My interest in the research came from environmental concerns about dumping
plastic waste in landfills, waterways, and major cities and towns. Geyer et al. (2017)
stated that there would be about 12,000 Mt of plastic waste by 2050 with the status quo of
plastic production and waste management. Plastic waste is not biodegradable, and
indiscriminate dumping harms marine life. Consequently, the environmental concerns led
to a further desire to venture into the plastic waste recycling business to address the
environmental problem. I do not have a relationship with the research topic, participants,
or the research area.
I adhered to the ethical standards stipulated in the Belmont report, which abides
with the principles of respect for the person, beneficence, and justice (National
Commission for the Protection of Human Subjects in Biomedical and Behavioral
Research, 1979). I treated my participants with respect, beneficence, and justice. Anabo
et al. (2019) presented an article on applying the Belmont report to online research
showing that the concept and application of justice were implicit and varied from the
original report. To address researcher bias in the interpretation of data and mitigate a
67
personal lens's effect, I used multiple data sources, interview protocol, member checking
of data, and data triangulation. These various instruments ensure research validity (Yin,
2018). Interview protocols (see Appendix A) ensured that I adhered to the interview
questions and did not introduce bias or derail the interview's objective. The interview
protocol provides a guide for using interview questions (see Appendix B) during the
semistructured interviews. The researcher can send the interview questions in advance to
the participants to increase the quality of their responses. Wadams and Park (2018) stated
that the researcher could mitigate against bias by using bracketing, unstructured
interviews, diverse peer review, thinking inductively, investigator responsiveness, and
critical reflexivity. Before I commenced data collection, I ensured that I received
institutional review board (IRB) approval to begin the fieldwork, which involved data
collection through semistructured interviews. I ensured data saturation in my data
collection process. I also confirmed that my research participants' selection was through
reliable trade organizations such as the plastic manufacturers' association and chambers
of commerce, including plastic recycling businesses.
Participants
Research participants must meet an eligibility requirement based on established
selection criteria (Fernández et al., 2018; Malesela, 2020). The research participants for
the study worked at small or medium-scale plastic recycling businesses that have been in
business for at least 5 years. The business owners were managing directors in plastic
recycling plants with work experience of no less than 5 years and at least 25 years of age.
The managing directors are strategic decision makers in the plastic recycling business.
68
The plastic recycling plants should also have an established supply chain for sourcing
plastic waste and clients to sell their recycled products.
A researcher uses many strategies to gain access to participants and ensure
successful data collection during the project's fieldwork phase (Peltoniemi & Suomi,
2019; Sharafizad, 2018). I selected my research participants from the chambers of
commerce and industry for plastic recycling companies in Nigeria, then narrowed down
the regions to southwest Nigeria. Akinso (2018) and Townsend (2019) also used similar
research approaches to access their participants. I also searched for a plastic
manufacturing association for plastic recycling businesses that meet small and medium-
scale recycling businesses. Furthermore, my strategy to reach research participants was
through emails and phone calls. I used the emails to send consent forms to the research
participants, who gave their consent for interviews through emails. I scheduled interviews
with my research participants according to my interview protocol. I similarly selected
plastic recycling businesses based on publications, Facebook, and internet search
providing information about plastic recycling businesses applying innovative strategies in
plastic recycling.
Research Method and Design
Research Method
Research methods are the strategies, processes, or techniques used to collect data
or evidence for analysis to uncover new information or create a better understanding of a
topic (Strijker et al., 2020). The research methods available to a researcher are
qualitative, quantitative, and mixed methods (Huyler & McGill, 2019). One main reason
69
for choosing a qualitative method is that there is no rich data on the practices of plastic
recycling businesses and the strategies used by their business owners to improve
profitability in Nigeria. Therefore, through this research, I sought the strategies used by
business managers to improve the plastic recycling business's profitability to provide rich
contextual data that otherwise would not be provided by a quantitative method. Busetto et
al. (2020) used the qualitative approach to research how to use and assess qualitative
methods. Ingram et al. (2019) also used qualitative methods to assess the integration of a
health promotion intervention into primary care to reduce cardiovascular disease risk
among underserved populations with diabetes in Sonora, Mexico.
A qualitative method was more aligned with the research question: What
strategies do small business managers in plastic recycling businesses use to improve their
profitability? A strategy is an approach used to achieve the desired result. Thus, a
qualitative method was the best way to understand business managers' real-life
phenomena in making strategic decisions to improve the recycling business's
profitability.
Researchers use the qualitative method to apply inductive inference and known
premises to develop untested conclusions (Azungah, 2018). Qualitative researchers use
data collection to explore a phenomenon, identify themes, and create a conceptual
framework. The research philosophy can be pragmatism (Clarke & Visser, 2019). The
researcher starts with the problem and aims to contribute practical solutions that inform
future researchers (Saunders et al., 2019). Additionally, qualitative research is realistic
since qualitative researchers explore the phenomena in natural settings. Therefore, the
70
qualitative method was the most suited for my research because it aligned with the
research question and the phenomenon intended for the study: the strategies used by
small plastic recycling business owners to improve profitability.
A quantitative researcher uses empirical data to support or disprove a theory (Al
Busaidi, 2020). The quantitative method consists of independent variables and dependent
variables. The researcher distributes questionnaires by the determined sample size in
some quantitative research. The researcher must develop the questionnaires on the
independent and dependent variables. The researcher then extracts the data from collected
questionnaires and analyzes the data using tools like SPSS to establish a relationship
between the independent and dependent variables. I did not choose the quantitative
research method because empirical data does not address my research question, which
requires rich data on what strategies business owners use to improve plastic recycling
businesses' profitability. The mixed method consists of qualitative and quantitative
research methods (Ramlo, 2020). Using the mixed method, the researcher combines
empirical and rich textual data. However, my research objective did not require
combining rich data with numeric data to explain the phenomenon to be studied.
Research Design
There are many different qualitative research designs that a researcher can use.
Common qualitative research designs include case studies, narrative, ethnography, and
phenomenology (Tomaszewski et al., 2020). A case study is an in-depth inquiry into a
topic or phenomenon in a real-life setting (Chowdhury et al., 2020). I used the case study
design to research strategies that small business managers use to increase profitability.
71
The researcher can use a case study inductively or deductively. A case study can be
exploratory, explanatory, or descriptive (Saunders et al., 2019). I selected the exploratory
case study design for this study.
A case study can have a single case or multiple case studies. Researchers select
multiple case studies to ascertain if the researcher can replicate findings across cases
(Yin, 2018). A researcher using a case study captures the case's complexity and changes
over time. It addresses the contextual and the conditions that interact with the case. A
case study can explain how a planned intervention or ongoing initiative functions.
Additionally, in a case study, the researcher must triangulate evidence from multiple data
types (e.g., interviews and documentation) to confirm and collaborate findings (Yin,
2018). Consequently, I used the multiple case study approach because I wanted to collect
rich data, and a multiple case study enabled me to achieve data saturation.
There are other qualitative research designs, including (a) ethnography, (b)
narrative, and (c) phenomenology. Ethnography entails studying cultures or the group's
social world (Saunders et al., 2019). Ethnography is the written account of people or an
ethnic group. Researchers using an ethnographic design implement a more interpretive
and naturalist focus by studying the people's language to write up cultural accounts (Kian
& Beach, 2019; Saunders et al., 2019). The ethnographic design is time consuming, and
the researcher’s involvement is intense because he has to do some grounding with this
approach (Saunders et al., 2019). Therefore, I did not use ethnography because I am not
studying people's cultures or their social work but exploring strategies to improve the
profitability of plastic recycling businesses.
72
The narrative design involves storytelling and a personal account that interprets
an event or sequence. Researchers using narrative inquiry seek to preserve chronological
connections and sequence events as the narrator tells (Saunders et al., 2019). A narrative
case study allows a researcher to analyze the linkages and relationships naturally and
socially constructive explanations to understand people's complex processes and make
sense of their organizational realities (Nowak-Dziemianowicz, 2020; Saunders et al.,
2019). The narrative design is generally associated with small purposive samples because
of its intensive and time-consuming nature (Saunders et al., 2019). It is likely to generate
large amounts of data from interview scripts and observational notes (Saunders et al.,
2019). Thus, I did not use the narrative case study because I researched a personal
account of the events' sequence and the chronological linkages to these events.
The phenomenological research design focuses on the participants' lived
experiences and is a strand of interpretivism philosophy (Sweet & Parker, 2019). The
research design also focuses on participants' lived experiences and recollections and
interpretations of those experiences (Saunders et al., 2019). Phenomenological
researchers are also concerned with generating meaning and gaining insight into those
phenomena. Ceylan and Çetinkaya (2020) used phenomenology for their medical
research on maternity nurses' views on barriers to early breastfeeding initiation. The
focus of the study is on lived experiences of mothers breastfeeding their babies. Tugce
and Demirkaya (2020) used phenomenology for their academic research on the role and
importance of social studies in gifted students' education. The focus of the study was on
the lived experiences of talented students in their education. Hence, I did not use
73
phenomenology because I am not researching the participants’ lived experiences, which
is common in the social and health sciences.
Data saturation occurs when a researcher’s analysis of additional data collected
from a new participant does not change the researcher's understanding of the
phenomenon (Tran et al., 2017). I ensured data saturation by collecting data until the
information was repeated (see Yazdani et al., 2020). Consequently, I used multiple case
studies to triangulate themes across different case studies and determine when there is a
repetition of data (see Saunders et al., 2019; Smith, 2018). I coded my data, member-
checked with the participants on the research interpretations, and shared my feedback.
Additionally, I adhered to an interview protocol to guarantee the collection of relevant
information to the research question. These techniques can help the data collection
process reach saturation (Lowe et al., 2018; Saunders et al., 2019). I knew I had reached
data saturation when the analysis of data collected from a new participant added no new
information to the strategies used by business owners to improve the profitability of their
recycling business.
Population and Sampling
There are more than 100 plastic recycling businesses in Nigeria. However,
statistics on the number of plastic recycling businesses are not readily available.
Townsend (2019) used a multicase study of six waste management businesses to study
leadership strategies to reduce operational costs in Liberia's waste management
businesses. Similarly, Akinso (2018) used a multiple case study of three soy processing
entrepreneurs to research the successful strategies for the survival of business owners in
74
Nigeria. Therefore, the sample size for this exploratory, multiple case study consisted of
nine small plastic recycling businesses in southwest Nigeria. I selected the southwest of
Nigeria because it has a larger concentration of plastic recycling businesses. In addition,
the southwest of Nigeria is one of the manufacturing hubs of Nigeria. The criteria for
selection of the participants were (a) business owners of plastic recycling plants, (b) have
a work experience of no less than 5 years, (c) at least 25 years of age, and (d) strategic
decision makers in the plastic recycling business. The plastic recycling plants had an
established supply chain for sourcing plastic waste and clients to sell their recycled
products.
Saunders et al. (2019) used many nonprobability sampling techniques: quota
sampling, purposive sampling, volunteer sampling, and haphazard sampling. Quota
sampling is a nonrandom sampling technique mainly using structured interviews as a
survey strategy (Saunders et al., 2019). Researchers use this sampling technique for
typically large sample sizes that necessitate the population's division and calculated quota
for each group. Purposive sampling is a technique where the researcher uses his judgment
to select cases that best answer the research question (Basri et al., 2020; Saunders et al.,
2019).
There are different types of purposive sampling. The type of purposive sampling
can be the extreme case, heterogeneous case, homogenous case, critical case, typical
case, and theoretical case (Saunders et al., 2019). Researchers use purposive sampling
normally for small sample sizes, where they can select informative cases. Volunteer
sampling techniques have to do with the participants' volunteering, called a snowball
75
sampling technique, or where the participants volunteer themselves, called a self-
selection volunteer sampling technique (Mattalia et al., 2020). The haphazard sampling
technique involves selecting the participant haphazardly because they are available, not
based on any organizational principles regarding the research question. The haphazard
sampling technique is known as the convenience sampling technique. Olorunshola (2019)
used purposive sampling for two similar small maritime businesses to study small
business sustainability strategies in the maritime industry in Lagos, Nigeria. The
relevance of this study is that I conducted my study in a similar location in Nigeria. Thus,
purposive sampling could also apply to my study. Likewise, Seid (2020) used
nonprobability purposive sampling to research strategies for sustaining minority-owned
small businesses. Hence, I used the nonprobability purposive homogenous sampling
technique for my research. The purposive homogenous sampling technique is useful for
an in-depth focus research type, has reasonable costs associated with its use, and the
researcher specifies the selection criteria.
Data saturation is when the researcher experiences no new data in the collected
data, and there is a repetition of information in the collected data (Guest et al., 2020;
Lowe et al., 2018). No new theme emerges from the data collection process (Lowe et al.,
2018). By using a multicase study, a researcher ensures that he can achieve data
saturation by comparing data for homogenous case studies of plastic recycling
businesses. Using techniques such as member checking improved the data's quality and
enabled the researcher to achieve data saturation. Additionally, I used field notes from
my semistructured interviews. Also, strict adherence to the interview protocol ensured
76
that I asked the interviewees the same questions. The information provided by
participants at the interview sessions allowed me to conduct methodological
triangulation. Data saturation can be thematic or theoretical (see Carmichael &
Cunningham, 2017; Guest et al., 2020; Lowe et al., 2018). Townsend (2019) used a
thematic data saturation technique to research leadership strategies for reducing
operational costs in waste management businesses in Liberia. Shirley et al. (2018) used
thematic saturation to study cessation-related information, motivation, and behavioral
skills in smokers living with HIV. Consequently, I used thematic saturation for my
research, member checking, field notes, and the use of semistructured interviews to
address my research question.
Ethical Research
The informed consent process involves the participant accepting the informed
consent form in Appendix D and listed in the study's table of content. I requested
informed consent through email or a signed consent form for a face-to-face interview. I
explained to the participant that his participation was voluntary and that he could
withdraw at any stage. I explained to the participant that his involvement contributes to
the existing body of knowledge on plastic recycling in Nigeria. I also let him know that
the interview sessions take about 30 minutes of his time to answer interview questions.
Also, I sent the interview question to him before the interview date. Van Nuil et al.
(2020) found five themes associated with the consent process in clinical studies, and they
are (a) words and regulation, (b) reimbursement, suspicions, and joining, and (c)
77
responsibilities. Finally, I delivered the participants' consent form after receiving IRB
approval and an IRB number.
Before I commenced the fieldwork, which consisted of getting signed consent
forms and interviewing participants, I received my IRB approval number 10-18-21-
10024367 from Walden University. The IRB approval meant that I had the approval to
interview participants. The IRB approval also implies that I am committed to following
ethical interview guidelines found in the Belmont Report (Office of Human Research
Protections, 1979).
I let the participants know they are at liberty to withdraw from an interview.
Whenever they felt they could not continue the interview, the participant indicated they
were no longer willing to participate, and I terminated the interview. I also let them know
there is no penalty for deciding not to continue. Likewise, I informed them they had
privacy and would make their own decisions.
I did not provide any incentive or compensation for participating in the study. I
did not offer any incentive to the participant because this is a qualitative study where the
participant is known. An incentive, such as a cash gift, to participate may violate the
Belmont Report's principles (Office of Human Research Protections, 1979). However, I
informed the participants that I would share the findings of my study with them.
The guiding ethical document for researchers is the Belmont Report (Office of
Human Research Protections, 1979). This document bounds the researcher to treat
participants in research with justice, respect, and beneficence. I treated my participant
with respect and ensured the transparency and integrity of all participants. I did not
78
coerce them into participating in the study or give a false impression of any direct or
indirect benefits from participating in the research.
I stored my participants’ interview data in a home safe for 5 years to protect my
participants' rights. My final document included the final Walden IRB number 10-18-21-
1004367. Also, the study document did not include the participants' names or other
information to identify the individual or his organization. I used codes to identify the
participants, such as P1, P2, P3, P4, and P5. I used codes to identify their businesses,
such as B1, B2, B3, B4, and B5.
Data Collection Instruments
I am the primary collection instrument for my research. Qualitative data collection
instruments are the mediums through which the researcher answers the research question
(Saunders et al., 2019). The participant answers the research question through structured,
semistructured, or nonstructured interviews. Researchers for rich, in-depth data favor
semistructured interviews. Structured interviews are used mainly for survey research,
where the same questions are in a standardized format (Saunders et al., 2019). For
example, Cheung et al. (2018) used a semistructured interview to study the train-the-
trainer design for green ambassadors in an environmental education program on plastic
waste recycling. Nascimento et al. (2019) used semistructured interviews for their study
on exploring industry 4.0 technologies to enable circular economy practices in a
manufacturing context. Similarly, I used semistructured interviews (see Appendix A and
Appendix B) to collect data on the research strategies business owners of plastic
recycling businesses use to improve profitability.
79
To improve this study's reliability and validity, I sent the final report of my
findings to the participants to review and verify that the results were correct. I also
triangulated data across different cases, cross-checking my field notes and audio
recordings. Hamilton (2020) used member checking, triangulation, and peer review in his
research on rigor in qualitative research, evaluating strategies among underrepresented
rural communities. I reduced bias in the interview process by adhering to the interview
protocol. I also utilized peer reviews of my study to improve the study's reliability and
validity.
Data Collection Technique
My research question is, what strategies do small business managers in the plastic
recycling industry use to improve profitability? Ssemugabo et al. (2020) used
semistructured interviews in their study on household solid waste management status in
Kuala Lumpa, Kenya. Similarly, to address my research question, I used semistructured
interviews. I was the primary data collection instrument for my research. Participants
provided answers to the research question through interview questions. I did not collect
secondary data from the participants on the company's sales and revenue, business plans,
and annual reports because they are unreliable for small businesses in Nigeria. Johnson et
al. (2018) used an interview protocol for their study on estimating on-farm food loss at
the field level. Similarly, I followed the interview protocol in Appendix A.
I ensured that interviews occurred in a quiet place with a door and were free of
distraction, where my participant could be at ease. Saunders et al. (2019) recommended
that a researcher conduct interviews with participants in an office free of distraction. I
80
scheduled the interviews conveniently for the participant. The interviews took no longer
than 30 min. Before the interview occurred, the participant provided a signed consent
form indicating a willingness to participate in the interview. I briefed the participant on
his right to leave the interview at any time with no penalty. I maintained eye contact with
the participant throughout the interview and used open-ended and follow-up questions. I
employed interview skills such as shifting focus to come back to the question.
The advantages of using semistructured interviews are getting rich data that the
researcher can analyze for themes and carry out coding. With the additional information
gathered on the business, the researcher can ascertain the business's financial state and the
length of time the company has been in operation. The disadvantage of this data
collection technique is that the participants may not be factual in their responses to the
interview questions. The company can also exaggerate documents such as annual reports
to show higher profits than realized.
I protected my participants' confidentiality by ensuring that I did not include their
names in my study. I used codes for the participants. I followed a checklist in my
interview protocol, such as ensuring that my recording device was working and having a
backup recorder in case of failure. I confirmed that I had a journal for the interview to
capture the participants' body language. Nation et al. (2020) used the member checking
technique to validate data in their research on improving water resilience through
environmental education. Similarly, I member checked the summary of the transcribed
interviews with the participants for correctness.
81
Data Organization Technique
Audio recordings are part of the collected data to study intensive triangulation of
qualitative research and quantitative data to improve recruitment to randomized trials
(Rooshenas et al., 2019). Lusambili et al. (2020) identified audio recordings as part of
their research on disrespectful maternity care in Kenya. Consequently, the electronic data
collected from my interview included transcribed audio recordings of my semistructured
interviews. I used reflective journals and labeling to keep track of records. The labeling
system involves using the codes for the participants and dates to save electronic copies of
Microsoft word and excel files of transcribed scripts. The electronic copy of interview
data was password-protected, such as field notes, summarized transcribed interviews in
Excel, and transcribed interview notes in Microsoft Word. I stored the electronic data in
an external hard disk, which I kept in a dedicated home safe. After 5 years, I will destroy
the external hard disk.
Data Analysis
The researcher can view data analysis as the process of giving meaning to the
collected data (Yin, 2018). A qualitative researcher carries out data analysis using the
triangulation approach. Data triangulation consists of four different types: Data
triangulation, investigator triangulation, theory triangulation, and methodological
triangulation (Abdalla et al., 2018; Yin, 2018). Data triangulation is used by the research
when there are multiple data sources (Saunders et al., 2019). The researcher uses theory
triangulation when the data analysis is for different views of the same data set (Yin,
2018). The investigator triangulation involves analyzing data sets from different
82
evaluators (Yin, 2018). The researcher uses methodological triangulation to explore the
various case study methods, such as transcribed participants' responses, open-ended
questions, field notes, observations, and secondary data (Yin, 2018).
A researcher can use methodological triangulation to confirm findings, increase
validity and enhance understanding of studied phenomena (Saunders et al., 2019; Yin,
2018)). In the methodological triangulation used by Nwanna-Nzewunwa et al. (2019),
they compare and contrast information obtained using the surgeon overseas' personnel
infrastructure procedure equipment and supplies (PIPES) tool with information obtained
simultaneously via three other methods: time and motion study (T&M); provider focus
group discussions (FGDs); and a retrospective review of hospital records. Through
qualitative data analysis, Walton et al. (2020) used methodological triangulation to
develop a unidimensional abbreviated version of the pain catastrophizing scale (PCS).
Similarly, I used methodological triangulation for my qualitative research on the
strategies business owners of small plastic recycling use to improve profitability.
There are five different steps for the analysis of data: (a) collecting data, (b)
grouping data, (c) regrouping data based on themes, (d) evaluating the information, and
(e) recognizing emergent themes (Yin, 2018). Birt et al. (2016) recommended using
synthesized member checking where participants can cross-check interview data after the
interview. The authors posited that this method leads to high-quality research. Similarly, I
commenced my data analysis by transcribing my recorded interviews and member
checking the summarized transcribed interview responses with the participant to ensure I
correctly captured their responses.
83
The thematic analysis identifies themes from transcribed interviews, field notes,
secondary data, and information websites (Saunders et al., 2019; Vaismoradi &
Snelgrove, 2019). It involves the researcher coding collected data for themes and patterns
based on the research topic (Saunders et al., 2019). P. Navarrete-Hernandez and
Navarrete-Hernandez (2018) used thematic analysis to analyze 40 in-depth interviews of
waste pickers forming recycling cooperatives in their study of waste pickers. Similarly, I
used thematic analysis to analyze company information on the website and audio
recordings from semistructured interviews with small plastic recycling business owners.
The next stage is removing redundant data and verbiage that may not provide
meaningful information (Saunders et al., 2019). Following this stage is coding the data
into themes and subthemes and then grouping the information into respective themes and
subthemes (Saunders et al., 2019). The researcher then compares these themes with the
conceptual framework to determine the research's findings or conclusions (Saunders et
al., 2019; Yin, 2018). Consequently, the final themes and subthemes become the study’s
findings on completing these processes.
I used the NVivo software version 12 Pro to code, group my data, identify
emerging themes, and determine when there are no new themes. Other researchers used
the NVivo software successfully in other qualitative research (Hawryluck et al., 2019;
Olubiyi et al., 2019). Bergeron and Gaboury (2020) recommended using NVivo for
realist evaluations. Additionally, computer-aided software ensured that the data analysis
was efficient and there was no error in the data analysis stage. The transcribed interview
responses were in Microsoft word and an input file into NVivo software. Likewise, I
84
extracted secondary information from the company website and put it in a Microsoft
Word file used as an input file on NVivo.
Researchers can use thematic grouping systems to identify and categorize themes.
Applying a thematic grouping system, Costantino et al. (2108) identified important
interagency collaboration features in their study of enablers and barriers to interagency
collaboration from senior managers, executive staff perspectives, and social network
analysis. Similarly, I created an excel file that identifies and categorizes the different
themes. I created a column for all participants summarizing each participant's response to
the interview questions in themes. According to my literature review's various themes, I
did the references in a theme column named T1, T2, T3, T4, T5, T6, and T7. I linked the
themes from participants P1 to P9, such as P1 to T3, P4 to T5, P3 to T1, and P5 to T2.
Consequently, I had a thematic grouping system to categorize themes emerging from the
data analysis. Furthermore, the thematic grouping system helped create a new theme cell,
if needed, from new studies published since writing the proposal.
Reliability and Validity
Reliability is the ability to replicate a study and maintain consistency in the study
(Saunders et al., 2019). Validity depends on how accurate the analysis of the results is
and if the research findings are generalizable (Saunders et al., 2019). Saunders et al.
(2019) stated that reliability and validity are essential in qualitative research for making
judgments about the research. Reliability is when a researcher can demonstrate that other
researchers achieved similar results by repeating the data collection process (Yin, 2018).
85
Therefore reliability means that another researcher can replicate my study and that I
maintained consistency in my study.
Reliability
Dependability. An alternative quality criterion for reliability is dependability
(Saunders et al., 2019). Dependability involves capturing all changes to produce reliable
research that other researchers can understand and evaluate (Saunders et al., 2019).
Raskind et al. (2019) used a triangulation, member checking, and interview guide to
verify their study's reliability in analyzing qualitative data analysis practices in health
behavior research and education. Similarly, I ensured the dependability of my study by
member checking of data interpretation, transcript review, pilot test, interview questions
validated by experts, interview protocol, participant observation protocol, data evidence,
and developing a study database (Saunders et al., 2019; Trochim, 2020; Yin, 2018). I also
achieved data saturation to ensure the dependability of the findings.
Validity
Qualitative study validity denotes my findings' credibility, transferability, and
confirmability (Saunders et al., 2019; Yin, 2018). Additionally, I achieved data saturation
in my study to ensure the findings' credibility, transferability, and confirmability.
Credibility. The credibility criteria involve establishing that qualitative research
results are credible or believable from the participant's perspective in the research
(Saunders et al., 2019). Credibility is an alternative quality criterion for internal validity
(Saunders et al., 2019). The main emphasis is to ensure that the participant agrees that the
collected data represents the information he provided through the semistructured
86
interview (Saunders et al., 2019). Raskind et al. (2019) used a triangulation, member
checking, and interview guide to verify their study's credibility in reviewing qualitative
data analysis practices in health education and health behavior research. Similarly, I
ensured credibility in this study by using member checking, triangulation, peer
debriefing, data, analysis, rigor, and participants' interpretations.
Transferability. Transferability refers to how qualitative research results can be
generalized or transferred to other contexts or settings (Trochim, 2020). Transformability
is an alternative quality criterion for external validity (Saunders et al., 2019). I ensured
transferability in this study by providing a detailed description of my research questions,
design, context, findings, and interpretations. I also ensured transferability by adhering to
the research design's data collection and analysis techniques, interview protocol,
participant observation protocol, and data saturation.
Confirmability. Confirmability involves corroborating or confirming results with
peers and researchers (Trochim, 2020). To ensure conformability in this study, I searched
for and described negative instances that contradict prior observations (Trochim, 2020).
Ellis (2019) recommended an audit trail to strengthen the confirmability of qualitative
research. Consequently, I performed a data audit to examine, analyze, eliminate bias, and
lead sound judgments. I also asked probing questions during interviews, questioning from
different perspectives and triangulating to enhance confirmability.
Data Saturation. I ensured I reached data saturation using member checking of
participants' interview scripts and data triangulation. Member checking on my
participants entails my calling them back to clarify these responses to summarized
87
transcribed interview scripts. I interviewed as many participants as needed to reach data
saturation. I defined a target sample for five. However, I reached data saturation after
nine participants. Yin (2018) stated that data triangulation reinforces the case study's
construct validity by creating evidence that converges. Also, Yin (2018) posited that
many sources provide a comparative analysis of the same phenomenon. I used multiple
data sources and approaches to analyze data, ensuring that I achieved data saturation.

analysis, and reliability and validity assessment. In Section 3, I discussed the presented

88
Section 3: Application to Professional Practice and Implications for Change
The purpose of this qualitative multiple case study was to explore strategies small
business owners in plastic recycling businesses use to improve profitability. I conducted
semistructured interviews with nine participants who had at least 5 years of work
experience in implementing strategies to improve the profitability of their plastic
recycling business. The data collection process included semistructured interviews and
transcribing and coding the recorded interviews. I used the interview protocol and
member checking in the field study phase. I then analyzed the data using the NVivo 12
software. I did methodological triangulation with company websites, information of
businesses on the internet, such as company Facebook and Instagram sites, and business
information in the chambers of commerce and corporate affairs commission. The data
triangulation showed that the information provided by the participants was correct. Most
participants did not offer company annual reports, business plans, or sales reports. From
the data analysis, three themes emerged: (a) strategies for sourcing plastic waste, (b)
strategies for managing workers, and (c) business strategies.
Presentation of Findings
One research question guided this doctoral qualitative study: What strategies do
small business owners in the plastic recycling industry use to improve profitability? The
participants of this study shared experiences of what they are doing successfully to
improve the profitability of their plastic recycling business. Some participants are
involved in the full value chain of plastic recycling, consisting of plastic waste collection,
separating plastic waste, washing, crushing, baling into units, treating the plastic waste,
89
pelletizing, and producing recycled plastic products. Fifty-six percent of the nine
participants produce and sell plastic recycled products. Forty-four percent of the nine
participants collect plastic waste, separate the plastic, wash, crush, bale it into units, and
sell or export it to plastic manufacturers or plastic recycling businesses.
The nine participants were business owners of plastic recycling businesses. The
participants were eligible to participate because they had been in business for more than 5
years and had successfully implemented strategies to improve the profitability of their
plastic recycling business. However, an exception to this was participant P1, who had 4
years experience but was included in my target sample because he had achieved
considerable success in his plastic recycling business in less than 5 years. Participant P1
also possessed a master’s degree in international business and management from the
United Kingdom and was a suitable participant for the study. P1 also exports plastic
waste out of Nigeria. The interview duration was from 12-20 min. Data saturation
occurred after interviewing the ninth participant when there were no new themes or
information to be gained.
The threshold for a major theme was 65%, and the threshold for a minor theme
was 30%. From the data analysis, three major themes emerged: (a) strategies for sourcing
plastic waste, (b) strategies for managing workers, and (c) business strategies. Seventy-
eight percent of the respondents brought up the major theme of strategies for sourcing
plastic waste, 56% brought up the point on the subtheme of plastic waste collection, and
33% mentioned the subtheme of processing and transporting plastic waste. Sixty-seven
percent of the respondents brought up the major theme of strategies for managing
90
workers, 33% brought up the point on the subtheme of training, and 44% mentioned the
subtheme of motivation. One hundred percent of the respondents discussed the major
theme of business strategies, 56% mentioned machines and technology, 44% talked about
periodic business reviews, and 33% discussed marketing subthemes.
Theme 1: Sourcing Quality Plastic Waste is a Challenge
Seventy-eight percent of the participants talked about the major theme of
strategies for sourcing plastic waste to improve the profitability of their plastic recycling
business. Plastic waste is the main raw material for plastic recycling. The disposal of
plastic waste in the environment is harmful because plastic does not degrade. The life
span for plastic degradation is at least 500 years (Priya et al., 2022). Even though plastic
waste is available, collecting it as a raw material has inherent challenges. Collection and
disposal centers are well established in developed western nations. These facilities are not
available in developing countries such as Nigeria. Aikowe and Mazancová (2021) found
that policymakers in Nigeria need to introduce waste segregation management practices
such as recycling bins in a Nigerian university and campaigns for waste sorting and
recycling activities. The university researchers' findings reflect a microcosm of the
underdeveloped collection centers in Nigeria. The plastic recycler has to set up a
collection system for the plastic waste that the plastic recycling business will use, which
mainly involves transporting plastic waste to the location of the plastic recycling
business. The research findings show that how plastic recyclers source, handles,
transport, and process plastic waste has a lot to do with the improved profitability of their
plastic recycling business. Table 1 provides all interviews' key terms relating to strategies
91
for sourcing plastic waste. Combined, the frequency of terms referring to strategies for
sourcing plastic waste equaled 28.48% of all the participants’ responses.

Plastic Waste Collection
Fifty-six percent of the nine participants discussed their strategies to source their
plastic waste to acquire cheap plastic waste. Satapathy (2017) identified sourcing quality
plastic waste as one of the key challenges for plastic recycling businesses. Table 2
provides all interviews' key terms relating to plastic waste collection. Combined, the
frequency of terms referring to plastic waste collection equaled 17.68% of all the
participants’ responses.

P1 established collection centers at different locations, ensuring his plastic recycling
business has cheap plastic waste. P1 captured the importance of collecting plastic waste
so that it is readily available at a cheap cost:
Basically, where the problem is in the collection, the collection is not done much.
So, to improve your profitability, you have to focus on the collection aspect of
your business. So, you have to really focus on the collection, so you have to invest
in the collection, because if you have your own collection, then you have the raw
material. And that means profitability too is quite stable. So, the area of focus
where we pay so much attention is the collection. So, if you really want to
improve the profitability, I will say the strategy is to focus on your collection.
P2 used a synergy with his waste management company to acquire free plastic waste:
So then, if you spend your money on getting raw materials, then your profitability
will not be high. So, we do not buy them. What we do is we are also into waste
management, so in all our clients, once we pick their waste, we do waste
93
segregation. We sort out their plastics and aluminum cans from the source, then
bind them separately and keep them.
P6 buttressed this same approach of sourcing free or cheap plastic waste:
So that is what we use now, so if we buy some from the factories, we can do two
runs, and he packs up to a tonne, or someone says come to my house and come
and pick up the plastics, and he goes and picks it up. But like I said, finding more
people that are not looking for incentives, or maybe cash, then cheaper incentives,
ultimately getting the products for free and now investing in logistics and
manpower, is more like the major reason for getting some profit.
The interview responses from participants P1, P2, and P6 show that business
owners must be innovative about collecting plastic waste for the recycling business. The
cheaper a business owner can source plastic waste, the lower their business expenses and
the more profits they can generate. Plastic recyclers collect waste by purchasing good
quality plastic waste. They process the waste through separation, washing, and shredding
and then sell it to plastic manufacturers or full-scale plastic recycling businesses.
Therefore, the strategies used by the participants improved the profitability of their
plastic recycling business by lowering the business expenses for purchasing plastic waste.
Additionally, only participant P6 discussed social entrepreneurship as a strategy
where the business owner identifies a social need and finds a way to solve this need.
Palacios-Marqués et al. (2019) found that distinctive marketing competencies mediate the
relationship between the degree of implementation of social entrepreneurship and
organizational performance. P6 commented that they educate people about waste disposal
94
and the harm to the environment and teach them about separating plastic waste.
Participant P6 said that when she renders this kind of service to the environment, they can
collect plastic waste-free from the community.
But I think the first thing is to be a social entrepreneur. If you seek more as a
social entrepreneur and focus more on what you give to the community, that
works out better. Also, if I had to start all over, I would do it differently. I will go
to the different neighborhoods. Though we were doing that and educating them, I
think self-regulation of encouraging people to separate their waste in their homes
and finding as many people that are not looking for incentives that buy into your
business model. So, you will literally be spending money on logistics and buying
fuel for the truck.
P9 used a verification process for the quality of supplied plastic waste and
assigned a percentage purity to what they received from the supplier, then paid the
suppliers based on the purity and weight of the plastic.
First of all, you have to know the materials you take. Because some of them that
you are bringing from the dump, the strategy they use there is they pick a lot of
impurities. So, they put a lot of PVCs that add weight to the product. So, when
you take it, let's assume they give you 3 tonnes, and the impurities inside the raw
material might be almost one-third. So, if you do not calculate well and remove
the right percentage you are supposed to remove, you automatically have a loss.
You will lose. So, you have to check the product they gave to you, analyze it very
95
well, and put your percentage very well. With those strategies, you are able to
increase and make your profits.
P7 stated that the main strategy of plastic recycling is sourcing the plastic waste cheap:
You know the key raw material is recycled waste, right. So the main strategy to
get profitable is to get that raw material, recycled waste, which is either plastic,
nylon, or whatever it is very cheap. Because that determines how much you will
make from it. If you get the material expensive, with the market value, the
recycling and end product and end-users might not be able to buy the product
because it will be very expensive. So, the key strategy is the raw materials,
recycled plastics, and waste, which is a bit cheaper.
Once more, participants P6, P7, and P9 demonstrate that the business owner must
be innovative in the strategies they deploy to acquire cheap and quality plastic waste. No
business wants to lose money paying for waste that has impurities, and no business owner
wants to incur high business expenses collecting plastic waste because impure plastic
waste or expensive plastic waste will erode business profits. Consequently, a plastic
recycling business owner must have an effective strategy that ensures that they purchase
quality and cheap quality waste, as shared by participants P6, P7, and P9.
Processing and Transporting Plastic Waste
Thirty-three percent of the nine participants discussed their strategies to process
and transport their plastic waste to reduce treatment and transportation costs. Whatever
treatment or processing the plastic recycler applies to the plastic waste improves the
quality or characteristics of the plastic waste. Suppose the plastic recycler can separate
96
the impurities from the plastic waste at the source. In that case, the plastic recycler
reduces the work workers do in the factory to filter the impurities from the plastic waste.
If the particle sizes of plastic waste fractions were standardized, the preprocessors could
minimize their transport costs, and recyclers could avoid fine particles and shredder steps
(Maisel et al., 2020). Also, suppose the plastic recycler can separate the plastic into the
different types of waste streams at the source. It follows that he reduces workers'
separation in the plastic recycling factory. Dijkgraaf and Gradus (2020) found that in the
Netherlands, the combination of post
separation of plastic and unit-based pricing has an
insignificantly small price effect on plastic waste. However, this may be because the
separation of plastic waste in the Netherlands is high compared with developing countries
(see Dijkgraaf and Gradus, 2020). Hence, processing plastic waste at the source improves
profitability by reducing the expenses the plastic recycling business will incur in
processing and treating the plastic waste in the factory.
Similarly, if the plastic waste is washed and shredded into small cuttings, it adds
to the value of the plastic waste (see Cioca et al., 2018; Maisel et al., 2020). Therefore,
the purified plastic waste, separated into the different waste streams, and compacted into
unit bales, attracts more cost than plastic waste, which has not undergone any plastic
waste treatment process. Table 3 provides key terms relating to the processing and
transportation of all interviews. Combined, the frequency of terms referring to processing
and transporting plastic waste equaled 33.81% of all the participants’ responses.

P3 stated that plastic waste recyclers transporting their plastic waste must
aggregate and compact the waste in baling units to reduce the transportation volume
space. By compressing the plastic waste, the recycler maximizes the amount of plastic
waste that can be transported per trip, thereby reducing the cost spent on transportation:
We deal on PPT. And then the transportation, how you transport your raw
material, which is the waste bottle makes a lot of sense in your profitability. If
you, because it is bulky stuff, so if you do not compact it into baling units, to
aggregate the weight, into a very good weight, you might load one tonne of PET
bottles in the entire truck, truckload, because it's very massive in terms of space,
which amounts to nothing. So, aggregation where baling is a way to achieve big
quantities with lower transportation. You need to have your raw materials
compacted into baling units into bales, so you will be able to load enough
quantities inside the truck before delivering it to your site. That is one way you
98
can maximize profitability, having control over cheaper transportation by
aggregating and baling your plastics into bales.
Furthermore, P4 captured the subtheme of processing the waste plastic, saying it is going
to be a lot more expensive to transport nonprocessed plastic waste:
So, the people that are collecting these plastics are collecting them together. And
what we need is just one of the components, which is polypropylene, PP. And the
first thing we try to do is to ensure that the suppliers know what we need and that
they do proper segregation to ensure that what they bring to us is what we need.
Unfortunately, they have to crush the plastic before they bring it to us because it is
going to be a lot more expensive for them to bring it as it is, because of the
transportation and all that. So, we try as much as possible to encourage them to
bring exactly, what we need, one way or another, so we don't need to do too much
work.
P4 also provided clarification on the need to separate waste and transport your plastic
waste:
Then we also have our vehicles that go to get these materials from wherever they
are and anytime when they are available. Once you depend on people supplying
your vehicles, maybe the time you need to get a vehicle, the vehicle may not be
available, or the driver may not be willing to go to wherever you need, could be
inside the bush and all that. And then the waste minimization, like I said, the
suppliers are supposed to do proper segregation, and sometimes they do not do
that. Sometimes even some of the suppliers deliberately add some unusable waste
99
because there is some waste that you hardly find any use for. Some of the plastic
they don't have a need for it. Some of them stuff the supplies because you buy
based on tonnage. You weigh whatever is being supplied to you. So, if you are not
careful, you have taken may be up to 45%, 60% of waste these things are not
useable to you, and then you end up with waste that you have to find a way of
managing. We also try to recover because, in the process of our own, we have to
do our own processes, we have to separate, to ensure that we have the right kind
of material, so we need to do our separation by washing or whatever method we
chose to use, but in the process of doing this separation, we also need some of
your waste, some of your real material into the waste, so we need to do recovery
of some of the material you can get from the waste, what it is supposed to be, our
supposed waste before we get to the final one that we are going to dispose of.
These are some of the ways we try to improve our profitability.
Participant P9 mentioned that bulk buying is another way to improve your profitability.
Instead of buying the plastic waste in small quantities, which will cost more
transportation, it is better to buy in bulk:
To add to what he is saying, the secret of this business is bulk buying. Because do
you know why I say it is bulk buying? For example, you want to load a certain
amount. You pay the same amount for a truck for the distance to go, and supply is
to come and bring. It is the same amount you pay when you know the number of
materials. Highest when it comes to offloading, maybe the expenses of offloading
and everything, highest additional maybe because of the quantity, the additional,
100
maybe extra 5k or 10k little you add, to the money you add to who will offload.
So, when you deal with bulk, you make lesser expenses in bulk. You spend more
money than when you buy bit by bit.
Participant P9 further emphasized that the profitability of the business depends on
the separation of impurities at the source:
How I overcame all these things like I told you before, is immediately I
discovered the secret of the business, which is these impurities and all the rest. So,
now, if I am crushing, I am crushing the rightful material. Then if they bring 10
tons and I crush 10 tons, I know that I will produce 9 tons or 9.5 tonnes or 9.2
tonnes. So, the loss, you will not have any loss at all. This is the key challenge, so
the key challenge is to ensure you watch over the product they are bringing you.
Once you are able to tighten up that particular area automatically, you will not
have any challenges again. You will start making your profit; even though you are
there or you are not there, the business will be moving.
In their responses, participants P3, P4, and P9 mentioned that impurities in plastic
waste contribute to increased transportation costs by making the plastic waste heavier.
Also, when the plastic waste is not properly segregated and shredded into small bits, it
increases transportation costs by the volume space it occupies in the trucks. Also, it is
better to bulk buy your plastic waste to decrease your transportation cost. Bulk buying
will reduce the number of trips you load a truck to your factory by optimizing the loading
capacity of the truck. Owning your transportation truck implies that the plastic recycler
can access quality and cheap plastic waste from different locations faster, improving
101
business turnover time. The treatment of plastic waste lowers transportation costs.
Reducing transportation costs reduces your business expenses. Sourcing plastic waste
locations close to your factory will reduce your transportation costs. Consequently,
processing plastic waste and reducing transportation costs improve the profitability of
plastic recycling businesses.
Links to the Literature. Satapathy (2017) discovered a shortage of quality
plastic waste in the plastic recycling business. Satapathy recommended that waste
managers pay attention to the supply chain for plastic waste and clients that generate
plastic waste. Most participants mentioned how they sourced plastic waste, as follows: (a)
P1 established plastic waste collection centers, (b) P4 and P6 mentioned having their
vehicles transport the plastic waste, and (c) P4, P6, and P7 discussed bailing the plastic
waste into units to maximize transportation space, and (e) P9 presented bulk buying of
plastic waste as a strategy to reduce transportation costs. Also, P9 emphasized the
importance of source separation of impurities from plastic waste. Olusunmade et al.
(2019) calculated plastic waste's energy potential in Nigeria and recommended that waste
recyclers treat plastic waste as a resource. Plastic waste segregation at the source of
plastic waste disposal is central to the success of the plastic recycling process (Banks et
al., 2020; Chow et al., 2016). Plastic managers must have their recycling plants close to
collection centers for plastic waste and handle plastic waste as a resource.
Furthermore, Cioca et al. (2018) found that a mechanical separation facility
(MRF) is more advantageous because they bring about more economic benefits by
reducing operating costs and improving return on investment (ROI). Standardized
102
particle sizes of plastic waste fractions can minimize transport costs (Maisel et al., 2020).
Some participants mentioned that waste segregation is also key to improving profitability
by reducing the plastic recycler's cost to separate the plastic waste into different plastic
waste streams and remove impurities. Therefore, separating plastic waste impacts the
profitability of a recycling business.
Eriksen et al. (2019) discovered a higher recovery rate with increased source
segregation and MRF efficiencies to about 17% of 100% plastic waste. Owojori et al.
(2020) recommended using three or more color-coded bins for recyclable, compostable,
and trash at the academic and administrative buildings to facilitate recycling and
partnering with waste recyclers to collect plastic waste. Zhang et al. (2020) found waste
characterization to be an influencing factor of recycling potential. Consequently, existing
literature supports the findings that separating plastic waste and processing it, such as
washing, compacting, shredding, and transportation, contributes to improved profitability
of the plastic recycling business.
Links to the conceptual framework. Corporate entrepreneurship is a construct
with many facets and consists of new business venturing, innovativeness, self-renewal,
and proactiveness (Boukamcha, 2019). The strategies used by plastic business recyclers
based on the theme of sourcing plastic waste show that most business owners exhibited
innovation, self-renewal, and proactiveness in collecting and securing a sustainable
supply of cheap quality plastic waste. Tănase (2020) found that transformational
leadership affects organizational innovation components of creativity, employee voice,
and knowledge sharing. Tănase also emphasizes that transformational leadership
103
positively impacts innovation in any organization by making workers creative. Seventy-
eight percent of participants used a different innovative transformational leadership
approach to secure their supply of plastic waste. Plastic waste is the major raw material
for any plastic recycling business.
For example, P1 established collection centers with collection teams, P6 designed
a cage for a self-styled medium-sized truck, and P9 bought plastic waste in bulk to reduce
transportation costs. Also, P4 compacts his plastic waste into baling units and segregates
and washes the plastic waste at the source. When participant P4 processes at source, the
business reduces transportation and separation costs. Hence, most participants exhibited
transformational leadership styles of innovation in the subtheme strategies for sourcing
plastic waste: plastic waste collection and processing and transportation of plastic waste.
Theme 2: Managing Workers Improves Profitability
Sixty-seven percent of the nine participants addressed the major theme of
strategies for managing workers towards improving the profitability of their plastic
recycling business. P2 discussed what they do with their staff and how they ensure that
their performance leads to the profitability of the plastic recycling business:
Human resources are one of the most challenging aspects of any business. You
know, but what we do is we look at those who studied related courses and then
bring them in, and then do a kind of training and induction for them. And then
what also motivates employees is if you have their interest at heart. So, once in a
while, we give bonuses and end-of-year awards to the best staff. We also issue
104
them job descriptions to ensure they know what they are employed to do and then
train them.
Table 4 provides key terms relating to strategies for managing workers for all
interviews. Combined, the frequency of terms referring to strategies for managing
workers equaled 27.51% of all the participants’ responses.

Training. Thirty-three percent of the nine participants discussed training workers
as a strategy to improve the profitability of their business. Training of the staff is a crucial
subtheme. The trained staff knows as much as the business owner, so they can make an
informed decision to move the company forward. Panagiotakopoulos (2020) found that
small business management training positively impacted organizational performance,
which translated to increased profitability, improved staff productivity, and low staff
turnover. Trained staff also implies that the utilized machinery for the plastic recycling
process does not break down due to operator error, costing the company huge amounts of
money to repair or replace. Trained staff can also identify the different plastic waste
streams, such as PET, PP, and PVC, and ensure proper identification, separation, and
105
aggregation. Table 5 provides key terms relating to training for all interviews. Combined,
the frequency of terms referring to training equaled 35.41% of all the participants’
responses.

P4 mitigates the challenges of workers spoiling sophisticated plastic recycling machinery
by training them:
On efficient machines, we try to train our staff very well. In the beginning, for
every machine we import, especially these sophisticated ones, we try to get
somebody from the manufacturers to man the machine at the onset, then to train
our staff very well to ensure that they get the best out of the machines.
Sometimes, we keep the expatriate staff for a long time to make sure that we don't
have a situation where the people are deliberately trying to sabotage you.
Participant P7 used training as the main strategy for getting informal plastic waste pickers
to supply plastic waste to his business.
106
Because one thing is that you have to train them and make sure that they are
basically trained all the time because plastics have different things. When I first
started right, most people were based on PP injection, which is plastic, bucket,
basins, and pans. That is what we were buying then. Then nobody knows about
the cover, right. Nobody knew that chair was very good then. Chairs were like so
anybody you tell to buy chairs was saying no, I do not want cover, and I do not
want chairs, they are not PP. So, because of my training and my understanding of
plastic recycling, I found out that covers are very good. So, I had to train my staff
that they crushed covers differently and buckets, basins, and pans differently.
Then as time goes on, I found out that the chairs are very good, and the batteries
are very good. So, all these things, I think the most important one is people you
train, and you keep on learning, by learning new things, learning different things.
Now we find that bottled water can be used for clothes with fiber. So there is so
much about plastics that we do not know about, so no matter what you do, you
cannot face on one or stay on one because if you stay on one, a lot of people come
to you invariably, so you learn different things, you learn different ways and
different materials on how to make different materials, how to use it to maximize
your profit, so there are a lot of different things. So, another thing is to train your
staff, because if your staff does not know what you know, right, then it will be
difficult to maximize your profits because they keep on making mistakes all the
time. But when they know what you know, you will find out that, basically, it is
like a stretch word test.
107
Participant P7 responded from the point of view of training as continuous
learning. Staff training is a continuous process if the business owner expects to get high
performance from them. Another facet of training is mentoring. The business owner may
not know all the aspects of the business and may need to be mentored by a resource
person or expert in plastic recycling. Participant P8 discussed meeting a resource Chinese
lady on social media who guided him on the needed machines for plastic recycling:
And basically, I met a Chinese lady who actually helped me a lot. And with the
guidance of the machinery part of the business. To be honest, I had no knowledge
of any machine before starting out with recycled plastics. So, I met with this
Chinese lady, I have never met her up till now in person, but she has helped me a
lot with guidance and so many things over WhatsApp. We were just
communicating. So she advised me on all the machines to buy, and we took her
advice. And then, going to the companies supplying the previous material also
opened my eyes, and I now saw many things from there.
It is also good to note that most manufacturers of plastic recycling machines offer
training to staff on how to operate their machines. In the case of participant P8, the
manufacturer was a Chinese company. The same point of training operators of plastic
recycling machines was mentioned earlier by participant P4. Trained staff will make
fewer mistakes and cause fewer losses for the company. Trained staff can operate
automated machinery that requires high staff literacy. Therefore a trained staff will
increase the profitability of a plastic recycling business.
108
Motivation. Forty-four percent of the nine participants discussed their strategies
to motivate workers to improve their business's profitability. Motivation is an essential
subtheme to strategies for managing workers because staff needs the motivation to
perform at a high level. Noviarita et al. (2021) discovered that leadership discipline,
motivation, and wages significantly affect employee performance. The high performance
of staff leads to higher profitability for the business. Staff needs to be motivated through
end-of-year bonuses, additional pay for meeting certain targets, and the business owners
showing individual interests in their personal affairs. Table 6 provides key terms relating
to motivation for all interviews. Combined, the frequency of terms referring to motivation
equaled 33.81% of all the participants’ responses.

Participant P1 stated that the main motivation for his staff is finance, putting extra money
in their pocket:
To be honest, it is just by setting goals, basically by setting goals and having a
team, a recruitment team. So, we set goals for them, and then we just physically
109
add pressure on them and make sure that we achieve these goals. To motivate
them to achieve this, we put incentives. We can tell you your target is 100 tonnes
this month, and if you do above 100 tonnes, we will give you NGN 2 for every kg
supplied or NGN 5 for every kg supplied. So as Nigerians, the main motivator is
finance, so once you can put money into the next man's pocket, he will try to do
the best that he can do. So, these are the little ways in which we use to set goals
for my teams by using incentives to achieve them.
Participant P2 captured this motivation of staff as the end-of-year bonuses:
And then what also motivates employees is if you have their interest at heart. So,
once in a while, we give bonuses and end-of-year awards to the best staff.
P4 says that the most effective strategy a plastic recycling business owner can use is a
motivated staff:
I think the most effective is staff because you can't do without the staff. If you
have problems with physical equipment, that is what you need to work on. If you
don't have good staff, you cannot go anywhere. Staff motivation is the most
important thing if you have motivated staff prepared to go out of their way to
ensure that the operations are working well. Then part of what we do is to pay
based on output and not just pay them because they are coming to work. So, if
you motivate them, you pay them higher when their output is higher, then they do
everything they can do to ensure that they give you the best. So, staff motivation,
I think, is the most effective and is at the center of everything that we have
discussed.
110
P5 stated that they implement a recovery plan when they are falling behind in their
quarterly targets by motivating staff for higher productivity through incentives:
Sometimes we will be able to recover in the next quarter, you know, by giving
some incentive to staff by doing overtime or what have you.
From the responses of P1, P2, P4, and P5, I conclude that motivated staff will
increase the profitability of a plastic recycling business by giving a higher output or
performance on their jobs. A motivated worker will innovate and commit to the
profitability of the business. Motivated workers are less likely to steal from the company,
be involved in fraudulent activities, or be unproductive. Motivated staff will deliver more
output and are more likely to innovate the business process. Business owners can
incentivize workers to deliver more results and find new clients for the business.
Therefore, motivated workers bring about increased profits for plastic recycling
businesses.
Links to the literature. Faisal et al. (2018) concluded that students could learn
recycling behavior using training strategies for K-12 students for plastic recycling
entrepreneurship. Nastase et al. (2019) also discovered that waste operators did not want
to take the additional financial burden of separating waste because they did not have any
incentives. Mattoo et al. (2020) showed that for the disposal of biomedical waste in
Pakistan, continuous training or awareness programs were necessary for hospital workers
to safely handle and segregate biomedical waste. The literature shows that training and
financial motivation are important in recycling plastic waste. Workers in plastic recycling
perform better in identifying and separating plastic waste.
111
Similarly, workers operating plastic recycling machines perform better if trained
and motivated. There is less operator error and breakdown of plastic recycling machines,
and they are motivated to increase their production of recycled plastic waste. Gerig
(2018) found that small business organizations (SBOs) in the participating mortgage
organizations succeeded by using continuing education and training, communication and
networking, and setting goals and planning effectively. Trained recycling plant operators
are empowered to run cutting-edge machines that consume less energy and increase
productivity. Advanced machines are automated, and only trained, and literate workers
can operate them. Consequently, training and motivation of plastic recycling workers
lead to improved business profitability.
Links to the conceptual framework. The fourth aspect of transformational
leadership is individualized consideration stimulation (Bass, 1985). A summary of the
transformational leadership used by plastic recycling business owners is as follows:
participant P4 pays workers based on output and trains his machine operators, participant
P1 gives financial incentives to his workers to meet targets and trains them to run the
collection centers, participant P2 trains his workers, gives end-of-year bonuses and shows
individualized interest, participant P5 gave incentives of overtime to workers for a
recovery plan, participant P7 trains his workers to identify the right plastic waste and to
separate the different plastic waste streams. A resource person mentored participant P8
on acquiring the right plastic recycling equipment. Boukamcha (2019) found that when
transformational leaders stimulate workers intellectually and motivate them
inspirationally, the workers demonstrate innovativeness, proactiveness, and new business
112
venturing. Accordingly, 67% of the participants identified the training and motivation of
workers as essential to improving the profitability of the plastic recycling business.
Mahdikhani and Yazdani (2020) found that transformational leadership positively
impacts service quality and improves team performance. Mahdikhani and Yazdani also
found that improved performance positively impacts service quality. Roibu et al. (2019)
also found that even though transactional leadership is more prevalent, transformational
leadership is desirable for the innovation and sustainability of Romanian hotels in the
long term. Therefore, 67% of participants used individualized consideration stimulation
of transformational leadership, training, and motivating their workers to improve the
profitability of their plastic recycling business.
Theme 3: Develop Effective Business Strategies
One hundred percent of the nine participants discussed strategies the plastic
recycling business used to improve its profitability. These business strategies are
adaptable to other sectors because the strategies have to do with sound business decisions
that the businesses must make in any business context and environment. Braun et al.
(2019) found that businesses need a delicate balance of strategy and business models for
long-term competitive advantage and profitability. The authors also found that a business
cannot use strategy at the expense of the business model and vice versa. One hundred
percent of the nine participants implemented different business strategies to achieve the
goal of improved profitability: (a) participant P1 used business partnership, participant P2
synergized by pooling funds from other waste management businesses, (b) P3 used a
strategy of marketing their recycled product and outsourcing plastic waste supply, and
113
participant P4 used investment in equipment, such as a truck and plastic waste processing
machines, (c) participant P5 used quarterly business reviews and new technology
conference center, and participant P6 used investment in a truck, (d) participant P7 used a
business strategy of equipment, energy-reducing machinery, and market relocation in the
face of stiff competition for plastic waste collection, and (e) P8 used a business strategy
of investment in equipment with backward integration and P9 used bulk buying and
selling plastic waste in higher-end markets. Consequently, the emerging subthemes under
the business strategy theme were machines and technology, periodic business reviews,
and marketing. Table 7 provides key terms relating to business strategies for all
interviews. Combined, the frequency of terms referring to business strategies equaled
21.35% of all the participants’ responses.

Machines and technology. Fifty-eight percent of the nine participants talked
about using machines and technology to improve their business's profitability. The use of
114
the right equipment and technology positively impacts the profitability of a plastic
recycling business. The equipment used in plastic recycling is cost-driven, such as plastic
waste separating machines, compactors, steam washers, crushers or shredders, pelletizers,
and plastic manufacturing machines. However, if the business owner acquires suitable
plastic recycling machines, it improves the profitability of their businesses. In the
agricultural sector in Sweden, Parvin et al. (2022) showed that intermediate machinery
size maximized farmers' net revenue. Table 8 provides key terms relating to machinery
and technology for all interviews. Combined, the frequency of terms referring to
machinery and technology equaled 18.02% of all the participants’ responses.

P3 mentioned the impact of these types of equipment on his recycling business
profitability:
We need to bale into 50 kg bales. Ordinarily, 50 kg may take a very wide space if
it is not baled. When you compact them into something that has to have a good
weight and smaller space, it will add up to your profitability. Now, another way
115
you can improve profitability is by cleaning, by having a clean end product,
because it is a waste, it is exposed. So, you have to have a washing system that
cleans the waste before you move it to crush. You need to clean your product
because you are priced according to the cleanliness of your product. If your
product is dirty, the person you are selling it to has to do the cleaning, which
means spending extra money. You need to keep people buying your goods
cheaper.
All of this involves money. The compacting technology has to make you get a
coil baling machine or compactor, something to compress, mostly, into a unit. The
baling machine has a kind of steel rope that binds the whole unit into something
that you will be able to lift. So, you need to spend money to acquire that, the
challenge there is the money to buy the equipment, and it is a specialized kind of
business altogether because you can even contract it out and give the people to do
the baling for you. Then, you pay them based on what they can be able to bale. It
is a value chain on its own.
P4 discussed using the right kind of machines with low energy utilization, high output,
and less labor as key strategies for improved profitability:
Also, our operations have to be efficient. You are working in a very competitive
environment, so if your operations are not sound, you will likely have a lot of
wastage along the way, and then the output will not be as much as you want. Then
in sourcing our machinery, we need to ensure that the right type of machine is
purchased, which helps to give you higher output and savings on power. These
116
machines consume a lot of power. If you don't get the right sort, then you gain a
lot in electricity, and the output may not be as much as the one that is more
efficient and effective. This also helps to lower the labor cost. Some equipment
may require more people to man them, but if you get the right type of machine,
you are going to have better profitability. Then we also have our own vehicles
that go to get these materials from wherever they are and anytime when they are
available. Once you depend on people supplying your vehicles, maybe the time
you need to get a vehicle, the vehicle may not be available, or the driver may not
be willing to go to wherever you need, could be inside the bush and all that.
P5 acquired dedicated state-of-the-art teleconference equipment to communicate with
clients online during the Covid-19 period when businesses lost customers. The internet
services they had were epileptic, and communicating with the customers in the pandemic
period was essential to avoid losing them:
For the Covid, we use telecoms. For the telecoms epileptic service, I now have a
more powerful network which we call the line of sight, which we put in our
company, a dedicated gathering point for conference calls.
P6 attributed the improvement in profitability due to the mini double-truck she purchased
and modified to have a cage behind to transport plastic waste:
I have bought four trucks since I started, so now I use mine. I bought this new
mini come to school, so whatever they come with it, the bus part of it and the
truck part of it. So, the back of it, I built like a cage, that you can see what is
inside. So that is what we use now, so if we buy some from the factories, we can
117
do two runs, and he packs up a tonne, or someone says come to my house and to
come and pick up the plastics, and he goes and picks it up.
So, like I said, we are not reinventing the wheel. And in the industry, at some
point, some people were considering setting up logistics companies to take care of
it. But with the quality of drivers they had then, it was impossible to make it
work. So, this model of buying a small truck so I can go to homes and go to
offices to pick up. And I think it is working, and I see the performance in the car
and do not treat it as a dump.
P8 stated that machines tripled their revenue and enabled them to get into the
recycling of new plastic waste streams such as PET bottles:
Yes, it helped us a lot because it wasn't easy with the machines. You know, the
situation of the country, it was not easy bringing the machines down here to
Nigeria from China. But when we bought the machines, it helped us a lot because
we could do so many things that we were not doing before. We bought shredders
and crushers and pelletizing machine. And then the Chinese people also advised
me, why don't you buy a film blowing machine that you can convert this waste
that you are recycling into other things? So, it is amazing how we did that because
we can buy, for example, a waste now from, let's say, from pure water or sachet
water waste, and we can convert it into bin nylon, you know, these trash bags.
This is just a small example that I have given you, but we can do 50 more with the
waste.
118
Yes, buying those machines has tripled our revenue, to be honest with you. It has
tripled our revenue, yes. It was a good choice. One thing I like about also is where
I am operating; in some of our plants, you see plastic waste, and people are
picking it up and delivering it to us.
Yes, there's a new technology in the world that I'm compacting this, you know,
PET bottles, like water bottles. It is called PET, now, the world is accepting it,
and we have invested a lot that people are not aware of that. I think it is something
that people should think about because right now, as we are talking, we have
imported the washing lines for those kinds of PET bottles and some other kinds of
machines that we can shred and make into flex. And you won't believe it. We plan
to export it to the United States of America and Turkey in Europe, so imagine it. I
think exporting Nigerian work to the USA is a great achievement.
Accordingly, participants P3, P4, and P5 stated that machines and technology
contributed to increased profits in their recycling businesses. The appropriate machines
and technology increase profits by reducing manpower and increasing the efficiency and
accuracy of the recycling processes. Machines can separate waste and reduce labor for
manual separation. Machines will shred and wash the plastic waste, detect impurities, and
reduce plastic waste supplier cheating. Machines will enable higher production and a
larger recycling scale, leading to improved profitability. Using technology, business
owners can move online to a wider market and overcome the challenges of pandemics
such as Covid-19. Thus, using machines and technologies by plastic recycling businesses
improves business profitability. However, machines and technology are expensive, so
119
businesses will have to start small or have access to some financing to acquire machinery
and technology.
Periodic business reviews. Forty-four percent of the participants identified
business reviews as a strategy for improving profitability. Participant P5 has quarterly
business reviews, where they review performance against certain key performance
indicators. At the beginning of a business year, participant P5 develops a short-term plan
of 1 to 2 years and a long-term plan of 1 to 5 years. Key performance indicators are
important because it helps a company know how successful it is in achieving its goals
(Sederavičiūtė, 2020). Participant P4 has an accounts department that determines the
overall production costs, which they subtract from sales revenue to determine their
profits. So, if the recycling business can achieve a certain production target in the period
under review, it has improved its profitability. Participants P9 and P1 used monthly
targets and goal setting, respectively. Participant P9 uses monthly targets to drive
profitability, so he establishes the target the business must achieve to realize certain
profitability. P1, on the other hand, establishes a target within a given period for his
collection team, and if they achieve these targets, they earn bonuses. Table 9 provides
key terms relating to the periodic business reviews for all interviews. Combined, the
frequency of terms referring to periodic business reviews equaled 21.60% of all the
participants’ responses.

P5 captured the business strategy of business reviews as follows:
Ok, we have monthly and quarterly review processes. We have the quarterly
business review that we do in our company. Like I told you, we set targets on a
quarterly, monthly, and yearly basis. To a 5, 3, 1 year plan, that is 5-year long-
term plan, 70% term up, but you know they are run at 100 terms per month. So,
we have KPIs and key performance indicators. With the KPI, for instance, we will
say that we shall make this bottom line, we will get 15% profit margin, just for
example, and during the process, let's say 10%, then we say what is happening. It
is not only in percentage, but we also have what percentage of our capacity we are
utilizing. We have a capacity that we are meeting, let's say we are to produce 50
tonnes in a month, and we are producing less than that, of course, it affects our
bottom-line and our turnaround time, I mean the turnover, it affects it. Therefore,
we may still be looking to see them, but our KPIs will show it if it is at a reduced
capacity. Another KPI that we set for ourselves is the turnaround time. So, we say
121
that we must produce 50 tonnes in a month, if we are now producing the 50
tonnes in 2 months, definitely affect our bottom-line. We have monthly will give
us 30 days review, but then KPI, which is the quarterly own will now say target
over actual versus actual, how have we done it. And then what will be our
recovery process for the next quarter?
The major thing is the quarterly review process. Yes, because you are there for the
money, so this one when we do a review, sometimes we find out that one product
is doing better than the other. So, although we have said that we should produce X
percentage of this product and Y percentage of the other product, Z percentage of
the other, if we know that one of those products is doing better, we will review
our percentage production. So, the thing is flexibility while still keeping our eyes
on the ball. So, we cannot afford to be rigid, so we have a long-term view, but we
have to manage the short-term output. Currently, for us to be in the business, we
have to be flexible, you know, still keeping our eyes on the ball.
P9 captured this subtheme of periodic business reviews in his following
explanation. In his case, the periodic business reviews are monthly:
So, like I wanted to tell you before, the profitability of any business is that you
must have a target. I used to give myself that I must achieve 40 to 50 tonnes
before the month runs to an end. And you know this business is a business of 5
naira, 3 naira business. Do you understand me? Let us assume that you have 10
tonnes in a month, and out of the 10 tonnes, you do your expenses; you do your
maintenance, you pay your workers, and you will see that the product that you
122
have at hand cannot give you anything, but with your targets for the month, ok
say, if you times 10 naira times 50 tonnes.
P1 also establishes goals which he reviews with his collections team monthly,
which he presented in the following:
To be honest, it is just by setting goals, basically by setting goals and having a
team, a recruitment team. So, we set goals for them, and then we just physically
add pressure on them and make sure that we achieve these goals. To motivate
them to achieve this, we put incentives. We can tell you your target is 100 tonnes
this month, and if you do above 100 tonnes, we will give you NGN 2 for every kg
supplied or NGN 5 for every kg supplied.
For participant P4 the accounts department performs the periodic business
reviews:
At the end of the day, we have an accounts department that checks the cost of our
operations viz-a-viz the production. I have told you that each process, like the
material we are buying, assesses what we are recovering from, but of course, the
actual, by the time you finish washing, you need to put these things into various
processes, and you get the final product. So, at the end of the day, what have you
recovered from what you have paid for, and then how much you are getting from
the whole thing? For the vehicles, for instance, you want to check the
maintenance cost, how much are we spending on maintenance, how much are we
spending on sundry costs, and are we getting value for our money? And then, of
course, the machines, are we getting a lot of damages on our machines, how long
123
do you use your machines without having damages. These are some of the ways
we try to check so how much profit are we getting out of this at the end of the
day.
Participants P1, P4, P5, and P9 mentioned that periodic business reviews
contribute to improved business profitability. A business needs to know if they are
profitable or running at a loss. The periodic business reviews allow them to assess their
performance for the period under review. From these reviews, they will know if they are
running behind on established KPIs and may need to recover in the next business review
period. Some participants review monthly by setting a monthly target and evaluating if
they met those targets. Every business must know if they are improving its profitability or
losing money. They need to evaluate if their implemented business strategy is improving
their profit. The more businesses review their performance, the more opportunity it has to
revise, reinvent or innovate what it is doing to be more profitable.
Marketing. Thirty-three percent of the nine participants mentioned the various
market strategies to improve their business's profitability. The participants P3, P4, P5, P7,
and P8, who participate in the full value chain of plastic recycling, manufacture recycled
plastic products that they sell to clients. The implication is that they have to sell their
recycled product and realize sales revenue from selling these products. However, only
participants P3 and P7 of the nine participants discussed marketing their recycled plastic
products. A study on US commercial banks by Chen (2020) showed that marketing
contributes to a bank's profitability. Table 10 provides key terms relating to marketing for
124
all interviews. Combined, the frequency of terms referring to marketing equaled 22.13%
of all the participants’ responses.

P3 specifically discussed the marketing of plastic recycling products in
outsourcing some recycling processes such as baling and supplies of plastic waste. So
that they could focus on the core business of manufacturing recycled products and
marketing their recycled product to clients:
You can outsource most of the time-consuming activities that divide your core
business and your profitability. You can have a target cost of raw materials, and
you contract it out and have an effective supply chain. Then concentrate on your
product and the marketing, your product, and the sales, then it will give very
strong profitability.
We can conclude from the comments from participant P3 that plastic recyclers
must have a market to sell their recycled plastic waste, and they must compete to have a
share of this market.
125
P7 discussed relocating to a virgin market when the competition is stiff regarding
plastic waste collection. Participant P7 considered relocating the market to collect his
plastic waste based on the stiff competition with other plastic recycling businesses. The
plastic recycling business should have an established market of plastic waste suppliers.
P7 narrates what he did to ensure that he has an established market for plastic waste
supply:
When I was in Lagos, it was so bad that everybody was into it, then in 2010 and
2009, there wasn't anybody doing it. Around 2012 it was so competitive that
everybody was doing it; even the Chinese came to Nigeria and started recycling
plastic. They took over all the dumps in Lagos state and were taxing them. So,
what I had to do was to travel to the north, Nasarawa, Keffi. So, I started to get
my recycling materials from there. So, like how do you say, I became a new thing
as well, over there, right. So, that is what you do is to keep on moving.
Do not stay in one place. When you stay in one place, you find that many people
will compete with you. And if you try to compete with some people, you will lose
a lot of money. That is the business, you can make a lot of money, and you can
lose a lot of money. You keep persisting, and you have to manage your strategies
and watch the effectiveness of how your strategies work, you make sure either
you make money or you lose money. So, when you find out that the competition
is becoming too much, instead of going and fighting, like if you have money, you
can stay and fight, like I have done some time in the past. But sometimes, you
126
cannot fight a Chinese man with dollars to buy raw materials when you have
naira. So, what you have to do is to go to a different location.
Participant P5 adjusted the prices of their recycled product downwards to ensure
that they kept their customers, or market share, during the Covid-19 period:
But the major strategy is to keep our long-term customers and reduce the price for
them so that our delta is small during our pandemic period. We have to keep our
customers; that is our approach.
The market where a participant buys plastic waste or sells recycled plastic
products is important to business profitability, as demonstrated by participants P3, P7,
and P5 in their interview responses. If a market is saturated, a business owner is faced
with rising demand for plastic waste and may have to look elsewhere for plastic waste.
Participant P7 relocated from one market to another in the face of stiff competition to
ensure they could still source plastic waste at a low price. In the face of the pandemic,
participant P5 adjusted his pricing to avoid losing his market share of recycled plastic
products. Participant P3 stated that it would be more profitable to outsource plastic waste
collection to a market of plastic waste suppliers. At the same time, they focus on the
selling of their recycled plastic products. All these market considerations are also driven
by whether the recycler is a full-scale plastic recycler, the market location, or if they are
only involved in the collection and resale to another market. Consequently, the marketing
strategies to buy and sell plastic waste and recycled plastic products are the key to
improved profits for plastic recycling businesses.

Links to literature. Turner and Endres (2017) found that networking, effective
business plans, and market differentiation strategies contribute to business success. Gerig
(2018) concluded that implementing business strategies in plastic recycling contributes to
business success, sustainability, and profitability. Automation enables mechanical
separators, cutters, washers, and shredders to be more productive and profitable (see
Ahmed et al., 2018; Cioca et al., 2018; Nascimento et al., 2019). The existing literature
review corroborates the findings of the subthemes under business strategies: machines
and technology, periodic business reviews, and marketing.
Links to the conceptual framework. The third aspect of transformational
leadership is intellectual stimulation, which refers to leaders’ challenge to their followers
to look at different perspectives to innovate and think outside the box (Bass, 1985).
Andersen et al. (2018) found that transformational leadership has a positive association
with the degree of shared understanding of professional quality, positively associated
with a high level of professional quality. Ghasabeh (2021) showed that transformational
leadership positively contributes to knowledge management. Bednall et al. (2018) found
that knowledge sharing mediates the relationship between transformational leadership
and innovative behavior. Therefore, using a transformational leadership style, the
participants positively impacted professional quality, knowledge management, and
innovative behavior in their plastic recycling businesses.
Furthermore, Yang and Yang (2019), in their study on the relationship between
transformational leadership and product and process innovation, made specific findings
on the interrelation between transformational leadership and competitive environment
128
process innovation. The authors found that there should be more process innovation in a
moderately competitive environment. Still, there should be less process innovation and
stronger adoption of transformational leadership in a fiercely competitive environment.
Participants P1 and P7 stated that the plastic recycling market is quite competitive.
Accordingly, all participants have adopted transformation leadership in the different
business strategies, such as investment in machines, transport vehicles, vehicle
modification, market relocation to a virgin market, establishing collection centers in
different locations, use of IT technology, marketing of the recycled product, and
outsourcing of plastic waste collection and use of machinery to process plastic waste.
Hence, all the participants adopted transformational leadership styles in implementing the
business strategies they used to improve the profitability of their plastic recycling
business.
Application to Professional Practice
There is a hiatus of information on what business owners of small and medium
enterprises in the plastic recycling business do in developing nations to improve their
profitability. For instance, there is no available data on strategies used by recycling
business owners to overcome low power supply and the lack of funding. The findings of
this study encourage many more entrepreneurs to venture into plastic recycling with a
shared knowledge from the research of what they can do to improve their profitability
and what they must avoid for sustainability. Plastic recycling businesses that are
struggling can benefit from the research by acquiring new strategies to deploy towards
improving the profitability of their business.
129
Successful plastic waste collection has a lot of impact on the plastic recycling
business. So how the plastic recycling business collects plastic waste is instrumental to
the business's success. The findings of my study focus on plastic waste collection, how to
establish teams, how to motivate the suppliers, and how to generate social goodwill that
could lead to your collecting plastic waste for free from the community. The study also
provides strategies to mitigate the sharp practices of plastic waste suppliers and use
suitable equipment. The study's findings can help a plastic recycling business owner
become more successful in collecting plastic waste.
Furthermore, the environmental concern is a weightier issue in developing nations
because of underdeveloped plastic waste collection centers and separation units. Not
many plastic recycling businesses or existing ones are thriving as they should, which is
one reason plastic recycling is low in African countries (Babayemi et al., 2019). Consider
that the profitability of a plastic recycling business directly impacts the environment's
well-being by reducing the amount of dumped plastic in the environment. The rich text
provided by this study may persuade a business entrepreneur to go beyond the business
plan, financial investment, and projected earnings to understand the intricate dynamics of
plastic recycling and what he needs to do to be profitable. Consequently, the study
contributes to practical knowledge to make plastic recycling businesses profitable to
achieve a chain effect for conserving the environment from dumped plastic waste.
Another important aspect is the management of plastic recycling workers as a
resource for the plastic recycling businesses. The findings show that business owners
should improve the use of transformational leadership to manage their workers. The
130
research provides information that staff training and motivation inspire the workers to
higher performance. Also, the findings show that plastic recycling business owners
intellectually inspire their workers towards innovation by using cutting-edge technology
in the plastic recycling business. The results also show that a plastic recycling business
owner can participate in some aspects of the plastic recycling value chain if the owner
does not have the necessary capital for machinery to produce recycled plastics. He can
start small and develop to a level where he can acquire machinery for full-scale plastic
recycling, i.e., begin as a plastic collection and processing center and then graduate to a
recycled plastic manufacturer. Therefore, the study provides information on managing
plastic recycling workers to improve profitability.
Implications for Social Change
The improved profitability of plastic recycling businesses from the findings of
researched strategies is beneficial to many areas. The first direct benefit is that recycling
businesses improve their profitability, enabling them to expand their business. Expanding
their businesses means the recycling business can employ more plastic workers. Their
wages can be improved, giving the workers a better standard of living and allowing them
to contribute more financially to society. Informal waste pickers can participate more in
the value chain. Rather than be a nuisance to society because of their lack of education,
they can pick up plastic waste, supply it to plastic waste recyclers, and make a living for
themselves. Therefore, plastic recycling businesses with increased profitability can
reduce unemployment rates in developing nations by increasing the employment of
workers in plastic recycling businesses.
131
The plastic recycling business consists of many value chains. Plastic waste
collection is one value chain, and plastic waste treatment is another value chain. Also, the
manufacturing of recycled plastic products is a third value chain, and the selling of
recycled plastic products is the fourth value chain. When plastic recycling businesses are
doing well, they engage more plastic waste suppliers in collecting plastic waste. Some
people may decide only to treat the plastic waste, separate, wash, compact, and shred.
The plastic recyclers that manufacture engage more hands to run the plastic recycling
plants and more distributors to distribute their recycled waste products. Accordingly,
there is a ripple effect from the contribution of the different value chains in plastic
recycling that translates to empowering more people, providing a means of livelihood for
many, and generating communal wealth.
Furthermore, when the plastic recycling businesses are more profitable, they have
more revenue to commit to corporate social responsibility, such as scholarships for the
less privileged and contributing industrial silos for waste disposal in strategic locations
for plastic waste disposal. For example, in many local governments in Nigeria, the state
government has failed to provide adequate waste disposal silos. If plastic recycling
businesses can do this, they will address the eyesore caused by the disposal of plastic
waste on the roads. The provision of plastic waste disposal silos can encourage the plastic
recycling behavior of the populace. Thus, the plastic recycling businesses can contribute
to the education of orphans through scholarship facilities. They can also assist the state
government in providing industrial waste silos and encouraging plastic waste recycling
behavior.
132
The ripple effect of plastic recycling businesses improving their profitability is
reduced plastic waste dumping in the environment. The citizens immediately begin to see
plastic waste as a resource. They become conscious of dumping plastic waste
indiscriminately if they can collect it and sell the plastic waste to suppliers for small
amounts of money. The citizenry can become involved in mitigating the environmental
problem of plastic dumping because they see that they can gain something from
collecting plastic waste and selling it at a small token to plastic recyclers. Consequently,
another direct impact of improved profitability of profitable plastic recycling businesses
is the reduction of plastic waste dumping through plastic recycling.
Recommendations to Action
The study’s findings show the strategies of plastic recycling business owners in
Nigeria. The study’s results showed that the plastic recycling business owners had to be
innovative and adaptive to improve their profitability. No business owner used the same
strategy showing the complex environment for businesses in developing nations such as
Nigeria. A large percentage of participants, 67%, used a transformational leadership style
to motivate and inspire their plastic recycling workers. However, all the participants
displayed the innovation aspect of transformational leadership in their business strategies.
From the nine-participant plastic recycling business owners, I derive my
recommendations from the three themes discovered in the study: (a) strategies for
sourcing plastic waste, (b) strategies for managing workers, and (c) business strategies.
The recommendations from my study are as follows: (a) plastic recycling business
owners should find the best location to collect their plastic waste and develop a quality
133
check process, (b) plastic recycling business owners should treat their plastic waste and
transport it at the cheapest cost, (c) plastic recycling business owners should utilize or
improve the use of transformational leadership with their workers, (d) plastic recycling
business owners should invest and utilize plastic recycling machines, and new
technologies in their plastic recycling process, (e) plastic recycling business owner should
have periodic business reviews to ensure improved profitability of their business, and (f)
plastic recyclers should develop a market for their recycled products with an adaptable
pricing model.
The results of this study apply to plastic recycling business owners, waste
managers, environmental policymakers, plastic manufacturers, managers of collection
plastic waste centers, and local state governments. The results of this study are also
applicable to business entrepreneurs seeking to invest in start-ups for plastic recycling
and for recycling businesses that need better strategies to improve their profitability.
Additionally, the study results apply to educational institutions teaching students about
plastic waste behavior and entrepreneurship in plastic waste recycling.
I will disseminate the results of this study to local, regional, and global businesses
in plastic recycling to provide a shared knowledge of strategies that plastic recyclers
utilize in complex environments to improve the profitability of their business. Also, I
plan to share the study’s findings with others through seminars, conferences, workshops,
and online podcasts. I plan to share with owners of plastic recycling businesses through
mentor programs and consultancy with business entrepreneurs seeking to invest in plastic
recycling. In addition, I will share my results with environmentalists interested in curbing
134
plastic waste dumping in developing countries and associations of environmental waste
managers, who can adopt some of the findings to promote plastic recycling businesses.
Recommendations for Further Research
The main purpose of this qualitative multiple case study was to identify the
strategies used by small business owners of plastic recycling businesses to improve their
profitability. The study’s findings showed that some business owners used
transformational leadership to motivate and train their workers to improve profitability.
Also, the study’s findings show that all the business owners exhibited the innovative
aspects of transformational leadership: (a) deploying business strategies for the collection
of plastic waste, (b) investing in and use of plastic recycling machines, and (c) pricing
and marketing of plastic recycled products to improve their business profitability.
Two main challenges that resonated with most participants are funding and
epileptic power supply. Therefore, one area for further research is the impact of funding
and power in improving the profitability of plastic recycling businesses in Nigeria.
Another area to consider for future research, even though only one participant used it, is
the impact of business partnerships in plastic recycling in improving the profitability of
the plastic recycling business. In this case, the target sample would be those plastic
recycling businesses that achieve profitability through business partnerships. A third area
to consider for research is whether it is more profitable for plastic recycling businesses
that manufacture recycled plastic to outsource the collection and treatment of the waste
plastic to concentrate on the production and sales of recycled plastics.
135
Furthermore, future qualitative researchers can target different states in Nigeria,
not only southwest Nigeria. Also, researchers can carry out further research in other
African countries such as Ghana, South Africa, and Egypt to get more regional strategies
that plastic recycling business owners use to improve their profitability. A qualitative
researcher could expand the interview questions to cover worker performance and
productivity. To mitigate against participants not being truthful in the interview
responses, the researcher could educate the participant on the importance of research
findings to business practice and how it could help other businesses improve profitability.
Future researchers could conduct quantitative research to establish the relationship
between independent variables, such as transformational leadership and profitability, with
a mediating role of dependent variables, such as motivation and training. A researcher
could consider conducting mixed methodology research to combine rich text with
statistics and numbers.
Reflections
The doctoral journey has shaped me into a scholar, understanding how to present
my facts with available research and contribute to the existing body of knowledge
through research. The doctoral journey is the most difficult undertaking to date for me. I
found the data collection quite challenging. The business owners I targeted for my
interviews were too busy, and it took weeks of persistence to secure an appointment with
any of them for an interview. The data collection phase took quite a while to complete.
The learning point was that through persistence and determination, any goal is
achievable.
136
My writing style has evolved due to this doctoral program. My writing has
become fluid and scholarly. I am more confident writing on any topic and can organize
my thoughts much better than before I started the program. I benefitted tremendously
from the constructive criticism and feedback from my chair, 2
nd
member, and URR. I
would also say that I was weak in using citations before starting the doctorate program,
but today I feel confident finding and using citations.
I started a new function twice during this program within the same company, so it
was a difficult challenge to balance the work with the academic requirements of the
doctorate program. In the initial period of the program, the demands placed quite a strain
on my family life. I had to take off one semester to achieve a better balance.
Consequently, completing the program for me represents a personal victory and
achievement. Additionally, completing the doctoral process has been fulfilling because I
sometimes wondered if I would ever get to the finish line.
Before starting the doctorate program, I considered starting a plastic recycling
business. I am so glad I took this research topic because, with my research results, I can
avoid the pitfalls of plastic recycling and apply my researched strategies toward running a
successful small-scale plastic recycling business. Suppose I had started a plastic recycling
business without the study findings; I may not have succeeded because plastic recycling
profits can be marginal if you do not apply suitable strategies. Therefore, I consider this
study a win-win in every aspect.
137
Conclusion
The purpose of this qualitative multiple study is to explore the strategies business
owners of small plastic recycling businesses have successfully used to improve the
profitability of their business. I conducted my study in the southwest and southeast of
Nigeria, with seven plastic recycling business owners in the southwest and two from the
southeast. The business owners shared the strategies they have successfully used
throughout the lives of their businesses to improve profitability. I used NVivo to organize
and analyze the data that I collected from the nine participants and discovered the
following themes: (a) strategies for sourcing plastic waste, (b) strategies for managing
workers, and (c) business strategies.
The findings of the research are consistent with most of the current literature. The
recycling business owners need to increase the use of a transformational leadership style
to manage the plastic recycling workers. The plastic recycling business owner uses
transformational leadership to remain innovative in the business strategies deployed and
remain profitable by constant innovation in the collection and processing of plastic waste.
As has been shown by most participants using transformational leadership, they are most
likely to use machinery and technology to increase the profitability of the recycling
business. As a transformational leader, a business owner is constantly learning and
training his workers to improve the profitability of his plastic recycling business.
Potential professional applications for this study include: (a) providing strategies
that recycling businesses can use to improve their profitability, (b) providing practical
information on how plastic recyclers can collect plastic waste profitably, (c) providing
138
information that encourages more plastic waste recyclers to invest in plastic recycling, (d)
reduce plastic waste dumping by improving plastic waste recycling, (e) encourage more
plastic recycling by increasing the participation in the different value chains of plastic
recycling, (f) offer available data to teach students at tertiary and secondary level how to
become entrepreneurs from plastic waste, and (g) improve plastic recycling behavior
among the citizenry. Plastic recycling is one way to combat the menace of plastic waste
dumping in our environment and the oceans. Plastic recycling businesses improve and
sustain their profitability if the business owners use the researched strategies from my
study.
