Garbage classification (English name: Garbage classification) generally refers to a series of activities that classify, store, classify and classify garbage into public resources according to certain regulations or standards. The purpose of classification is to increase the resource value and economic value of garbage, and strive to make the best use of it.

Garbage belongs to the public's private goods during the classification and storage stage. After being classified and released by the public, the garbage becomes a regional quasi-public resource of the community or community where the public is located. Judging from the methods of domestic garbage classification in domestic and foreign cities, they are generally classified according to the composition and amount of garbage, combined with the resource utilization and disposal methods of local garbage.

Carrying out garbage classification and collection can reduce the amount of garbage disposal and treatment equipment, reduce the treatment cost, and reduce the consumption of land resources, and have several social, economic, and ecological benefits.

From May 1, 2020, the "Beijing Municipal Waste Management Regulations" will be implemented.
