Garbage classification (English name: garbage classification) generally refers to a series of activities that classify and store garbage according to certain regulations or standards, and then turn it into public resources.

The purpose of classification is to improve the resource value and economic value of garbage, make the best use of it, 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.

Garbage belongs to the public's private articles in the stage of classified storage. After being classified by the public, it becomes a regional quasi-public resource in the community where the public is located.
