wastes. Algal biofuel chemistry modifies algal strains for optimizing lipid
yields. Lithium-ion battery electrolytes preclude thermal runaway enhancing
EV safety. Flow battery chemistries like vanadium, zinc-bromine unlock low-
cost energy storage for renewable energy grids. Hydrogen, another
promising carbon-free carrier, relies on chemistry to develop safer, smaller
storage mediums. Overall, renewable energy commercial viability
increasingly banks on sustainable materials and process chemistries at lower
costs and larger scales.
Green Chemistry in Industry
Green chemistry principles are revolutionizing manufacturing through the
design of benign products and processes while preventing pollution.
Innovation targets benign solvents replacing toxic organics, developing
atom-economic syntheses with little waste. Benign-by-design approaches
minimize hazardous inputs from the start based on structure-activity trends.
Catalytic reactions achieving selective transformations in water at mild
temperatures eliminate byproducts and unit processes.
Biomimetic green syntheses draw inspiration from nature’s metabolic
precision. Intensified processes harness microreaction equipment for
continuous processing which slashes waste generation. Green engineering
strategies redesign unit operations and equipment for cleaner manufacturing
through efficient separation and purification techniques with low energy use.
Chemistry plays an active role in developing bioplastics, biocoatings, bio-
based solvents and green building materials from renewable feedstocks as
more eco-friendly drop-ins for petroleum-derived chemicals. Metrics for
quantifying sustainability at molecular to industrial levels guide the transition
towards circular economies.
Pollution Remediation and Waste Management
Effective remediation demands harnessing chemistry for restoration of
contaminated lands, waters and air. Phytoremediation utilizes plant-microbe
synergies engineered through metabolic engineering and genetic
manipulation of hyperaccumulator species for removing metals, explosives
and hydrocarbons from soils. Chemistries design advanced oxidation
processes harnessing photocatalysis, Fenton’s reactions and ultrasonication
for treatability evaluations and complete mineralization of recalcitrant
organic pollutants in wastewater.
Nanotechnology creates photocatalytic, conductive and adsorbent
nanomaterials for selectively remediating multi-contaminant, difficult sites
efficiently. Chemistries design molecularly imprinted polymers and
dendrimers which selectively extract priority contaminants even at ultralow
levels from aqueous environments. Microbial fuel cell research harnesses
waste-fed microbial electrolysis for desalinating brackish waters or powering
bioreactors for on-site waste treatment. Advancing waste treatment methods
through chemistry unlocks opportunities in resource recovery from post-
consumer plastics and municipal/industrial wastes.
Sustainable Chemistry and Materials
Sustainable materials development employs green chemistry principles in
tandem with life cycle assessment tools to design non-toxic and eco-efficient
materials. Biopolymers manufactured from agricultural waste-derived sugars
offer renewable substitutes for petroleum plastics. Nanocellulose chemistries
transform agricultural residues into high-performance, biodegradable
nanocomposites harnessing properties of nanoscale cellulose. Phase change
materials incorporating salts or paraffins can regulate building temperatures
passively for efficient heating/cooling.
Semiconducting polymers enable low-cost, flexible photovoltaics and organic
light-emitting diode displays. Microencapsulation techniques packaging
phase change oils within polymers enable thermal energy storage in building
materials. Developing moisture-curable coatings without volatile organic
compounds reduces emissions. Conductive concretes laced with carbon
nanostructures enable deicing, energy harvesting and corrosion monitoring
applications of concrete infrastructure more sustainably. Chemistry of new
materials holds promise transitioning energy, construction and
manufacturing sectors onto greener trajectories.
Green Analytical Chemistry
Environmental monitoring and analytical testing require green chemistry
approaches to minimize waste, utilize safer solvents and integrate
automation for high-throughput analyses. Microfluidic biochips afford
multiplexed, portable assays for on-site detection with picoliter sample
volumes. Surface plasmon resonance and quartz crystal microbalance
sensors enable real-time, label-free, reusable pathogen/biotoxin detection.
Green solvent formulations replace toxic organics with ionic liquids,
switchable hydrophilicity solvents and compressed carbon dioxide for
extractions and chromatography.
Miniaturization of analytical procedures into microchips and reactors
conserves sample/reagents through integrated heating, mixing and
separation capabilities leveraging microscale fluid flows. Paper-based sensors
provide inexpensive, disposable diagnostic platforms printed with colored
reagents for low-resource settings. On-line, in-situ instrumentation measures
