The traditional single garbage treatment method is no longer suitable, and the comprehensive treatment of garbage is a reasonable and economic method. The development trend of garbage treatment gradually forms garbage recycling, treatment rationalization, operation cost reduction, economic benefit improvement and the like, and the key for realizing the garbage recycling is garbage classification and sorting.

Due to the growing population and the proliferation of resource consumption, limited resources are being overdrawn and global resources are facing unprecedented pressure. The recycling of the renewable resources is beneficial to repairing the damage of human beings to the nature and improving the living environment, and the comprehensive cost of utilizing the renewable resources is relatively low.
