[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, life and other activities. Organic solid waste is divided into 7 basic types: animal manure; crop residues; domestic sludge; food production waste; industrial organic waste; wood processing production waste; and domestic garbage.

[0003] The existing patent application number is CN 202120659860.1, which discloses a sorting device for recycling organic solid waste.
