There are some benefits to the environment. 1. It can reduce the harm of harmful garbage to the environment. The resulting garbage, there are a lot of garbage can not be recycled, but also contains highly toxic. For example, the parts and components of many electronic products are highly toxic. If they are not classified and treated like ordinary garbage, these toxins will be released into the environment, causing great pollution to water and air. These pollutants will eventually enter the human body through a variety of ways, making a lot of people sick, which is a very terrible thing.

2. Garbage classification can reprocess recyclable waste and realize the reuse of waste. For example, the kitchen waste and peel eaten in our kitchen can be used to fertilize the fields to produce organic melons and fruits, reduce the use of chemical fertilizers and make the land healthier. Waste paper not used in the office can also be recycled and made into paper, which can effectively reduce deforestation. The environmental benefits of garbage classification are not shown directly, but through these indirect ways.

3. garbage classification can also reduce the occupation of land. Every city needs a large piece of land to deal with garbage, whether it is traditional incineration or other treatment methods, the occupation of land is very large. After sorting, a lot of garbage can be disposed of without occupying land, such as domestic waste can be sent directly to the farm, rather than the need for a special place to pick up and then sent to the farm. The saved land can be used for other purposes, and it is a very good choice to build houses or parks, so as to create a more comfortable living environment for people.

Promoting garbage sorting has become one of China's top priorities. The Chinese government has invested 21.3 billion yuan (3 billion U.S. dollar) to speed up the promotion of domestic waste classification to meet the needs of domestic waste classification and disposal.
