How to identify the colors (four colors) of garbage classification?

It mainly includes 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.

Plastics: all kinds of plastic bags, plastic foams, plastic packaging, disposable plastic lunch boxes and tableware, hard plastics, plastic toothbrushes, plastic cups, mineral water bottles, etc.

Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, thermos bottles and so on.

Metal objects: mainly including cans, cans, etc.

Cloth: mainly includes discarded clothes, tablecloths, washcloths, 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 compared with the same output, the pollution is reduced by 74%; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every 65,438+0 tons of scrap steel can be recycled into 0.9 tons of steel, which saves 47% of the cost and reduces 75% of air pollution and 97% of water pollution and solid waste compared with ore smelting.

Non-recyclable:

Kitchen waste

Include 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 brick and tile ceramics, muck, toilet waste paper, paper towels and other wastes, shells and dust that are difficult to recycle except the above-mentioned 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, nuts and chicken bones are all kitchen waste.

Toilet paper: Toilet paper and toilet paper are both soluble in water and are 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 kitchen waste into the trash can and throw plastic bags into the "recyclable garbage" bucket.

Shells: In garbage classification, the symbol of "shell and melon skin" is peanut shell, which really belongs to kitchen waste. Waste cooking oil left at home is also classified as "kitchen waste".

Dust: In garbage classification, dust belongs to "other garbage", but litter belongs to "kitchen waste", including failed flowers at home.

Toxic and hazardous wastes:

Waste containing heavy metals, toxic substances harmful to human health or actual or potential harm to the environment. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some household appliances, expired drugs, expired cosmetics and so on. These wastes are usually recycled or landfilled separately.
