What is garbage sorting?
Garbage classification is to classify garbage according to recyclable and non-recyclable methods.
Human beings will produce a lot of garbage every day, and a lot of garbage will be recycled without classification and discarded at will, which will cause environmental pollution. Garbage classification is to put garbage into the source by classification, and make it become a resource again through sorting, clearing and recycling.

What are the benefits of garbage sorting?
1. Reduce land erosion
Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage sorting, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
Step 2 reduce pollution
Garbage disposal in China mostly adopts sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; Insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment.
Waste plastics in soil will lead to crop yield reduction, and abandoned waste plastics are eaten by animals by mistake, resulting in accidents of animal death from time to time. Because it can also reduce the harm than recycling.

What does harmful waste include?
Harmful waste includes: waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs and other wastes that need special safety treatment.
Other wastes include: tiles, ceramics, slag, and wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Advantages of garbage sorting
Most of the garbage disposal methods are in the traditional way of stacking and landfill, occupying tens of thousands of acres of land; And mosquitoes and flies fly around, sewage overflows and stinks, which seriously pollutes the environment. Therefore, classified collection of garbage can reduce the amount and equipment of garbage treatment, reduce the treatment cost and reduce the consumption of land resources, which has social, economic and ecological benefits.
The advantages of garbage sorting treatment are as follows:
1. Reduce land occupation: Some substances in domestic garbage are not easy to degrade, so that the land is seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
2, reduce environmental pollution: waste batteries contain toxic substances such as metal mercury and nylon, which will cause serious harm to human beings; Waste plastics in soil will lead to crop yield reduction, and abandoned waste plastics are eaten by animals by mistake, resulting in accidents of animal death from time to time. Therefore, recycling can reduce harm.
3. Turning waste into treasure: China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, which account for 8-15% of domestic garbage. One ton of waste plastic can recycle 600 kilograms of diesel oil. Recycling 1,500 tons of waste paper can avoid cutting down trees used to produce 1,200 tons of paper. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource.

Significance of garbage classification
1. Separate kitchen garbage with perishable organic components to provide high-quality raw materials for garbage composting and produce high-quality organic fertilizer, which is conducive to improving soil fertility and reducing fertilizer application.
2. The kitchen garbage with high moisture content is separated, which improves the incineration calorific value of other garbage and reduces the difficulty of secondary pollution control in garbage incineration. The content of pathogenic bacteria is beneficial to the harmless treatment of garbage, which reduces the risk of water, soil and air pollution in garbage treatment, classifies harmful waste, and reduces heavy metals and organic pollutants in garbage.
3. Classifying harmful waste reduces the contents of heavy metals, organic pollutants and pathogenic bacteria in garbage, which is beneficial to the harmless treatment of garbage and reduces the risk of water, soil and air pollution in garbage treatment.
4. Different kinds of garbage are diverted, which greatly reduces the amount that eventually enters the sanitary landfill and prolongs the service life of the landfill.
5. Improve the recycling ratio of waste products, reduce the demand for raw materials and reduce the emission of carbon dioxide.
