The significance of garbage classification:

1, reducing land occupation

Step 2 reduce pollution

At present, sanitary landfill or even simple landfill is mostly used in garbage disposal in China, covering tens of thousands of acres; Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment.

Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can also reduce the harm.

Step 3 turn waste into treasure

30%~40% of domestic garbage can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.

Moreover, other substances in garbage can also be transformed into resources, such as food, vegetation, fabrics, etc., which can be composted to produce organic fertilizer; Garbage incineration can generate electricity, heat or cool; Bricks and lime soil can be processed into building materials and so on.

Recycling is the best way to solve the garbage problem if the garbage generated in the consumption link is classified in time.
