Wet garbage refers to perishable garbage, such as kitchen garbage, expired food, Chinese medicine residue and other domestic garbage. In the transportation of wet garbage, if it is pure liquid garbage, it should be directly poured into the sewer. If there is packaging, the packaging bag should be removed and delivered according to the classification.

In the stage of classified storage, garbage belongs to the public's personal belongings. After the garbage is classified by people, it is put into the quasi-public resources in the nearby area, and finally it is classified and transported to the garbage concentration point, becoming a non-exclusive public resource.
