Recyclable: It mainly includes five categories: waste paper, plastic, glass, metal and cloth.
Waste paper: mainly including newspapers, periodicals, books, various wrapping papers, etc. However, it should be noted that paper towels and toilet paper are too water-soluble to be recycled.

Metal objects: mainly including cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.
These wastes can be recycled through comprehensive treatment, reducing pollution and saving resources. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.
Non-recyclable: kitchen waste includes food waste such as leftovers, bones, roots, leaves and peels. After in-situ treatment of compost by biotechnology, 0.6~0.7 tons of organic fertilizer can be produced per ton.
Other garbage: including bricks and tiles, muck, toilet waste paper, paper towels and other hard-to-recycle wastes, shells, dust, etc. other than the above-mentioned kinds of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
In fact, great bones are classified as "other rubbish" because they are "hard to corrode". Corn kernels, nut shells, fruit kernels and chicken bones are all kitchen waste.
Toilet paper: Toilet paper and toilet paper are soluble in water, not recyclable "paper". Similarly, there are pottery and cigarette cases. Bagging of kitchen waste: Ordinary plastic bags, even though degradable, are far more difficult to corrode than kitchen waste.
In addition, plastic bags themselves are recyclable garbage. The correct way is to dump the kitchen waste into the trash can and throw the plastic bag into the "recyclable garbage" bucket.
Shell: In garbage classification, the logo of "shell melon skin" is peanut shell, which really belongs to kitchen garbage. Waste cooking oil left at home is also classified as "kitchen garbage".
Dust: In the classification of garbage, dust belongs to "other garbage" and litter belongs to "kitchen garbage", including flowers that have failed at home. Toxic and hazardous waste: waste containing heavy metals, toxic substances harmful to human health or causing actual or potential harm to the environment.
