Glass mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal objects mainly include cans and cans. The fabric mainly includes discarded clothes, tablecloths, face towels, school bags, shoes, etc.

Hazardous waste includes waste batteries, waste fluorescent tubes, waste water silver thermometers, expired medicines, etc. These wastes need special treatment.
