The main categories of recyclable waste mainly include waste paper, plastic, glass, metal and cloth.

Waste paper: mainly includes newspapers, periodicals, books, various wrapping papers, office paper, advertising paper, cartons and so on. However, it should be noted that paper towels and toilet paper are too water soluble to be recycled. Plastics: mainly include all kinds of plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins, etc.

Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects: mainly including cans, cans, etc.

Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Comprehensive treatment and recycling can reduce pollution and save 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%. Kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels, can produce 0.3 tons of organic fertilizer per ton by in-situ composting with biotechnology.

Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment. Other wastes include brick and tile ceramics, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

2. What are the tips for garbage sorting?

Benefits of garbage sorting

The benefits of garbage sorting are obvious. After sorting, the garbage is sent to the factory instead of landfill, which not only saves land, but also avoids the pollution caused by landfill or incineration, and can also turn waste into treasure. For example, waste batteries called "mini killers" all contain heavy metals such as mercury or cadmium. If these heavy metals are left underground, they can easily leach into groundwater through rainwater, causing serious persecution to water resources and land. The waste battery contains a variety of useful metal minerals, and its recycling value is very high. It is precisely because of the serious harm and special recycling value of waste batteries that many countries prohibit them from being mixed with garbage. Japanese communities have this kind of yellow bucket, which separates button cell from others. Another example is biological waste such as leftover lettuce and eggshell skin, and kitchen waste such as picked Chinese cabbage leaves, but they can all be used as good organic fertilizers. Like this big nano-dream biological waste processor in Huaibai community, biological waste can be dried and crushed to make efficient organic fertilizer. Residents can use it to grow flowers and grass. Compared with fertilizer food, vegetables grown with them are safe and healthy, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste. If all of them can be turned into organic fertilizers, it can not only save land for landfill, but also save vehicles and energy for transporting them and prevent them from breeding mosquitoes, flies and bacteria.

So garbage sorting has many advantages.

Introduce the environmental protection classified trash can.

Generally speaking, the common environmentally-friendly classified trash cans are divided into green, yellow and red.

Green is used to put recyclable garbage, recyclable garbage: paper, plastic, rubber, metal, glass and so on.

Yellow is non-recyclable garbage, non-recyclable garbage: mainly kitchen garbage, including peels and vegetables.

Skin, leftovers, etc.

Red toxic and hazardous wastes: batteries, fluorescent tubes, mercury thermometers,

Paint bucket, medicine, cosmetics, etc.

3. Garbage classification in Hangzhou

Garbage includes industrial waste residue and domestic garbage. Industrial waste residue refers to the waste produced in the process of industrial production and processing, mainly including coal grindstone, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste residue. Domestic waste is mainly kitchen waste, waste plastics, waste paper, broken glass, metal products, etc. In cities, due to the increasing population, domestic garbage is increasing at the rate of 10% every year, which constitutes a major public hazard.

Classification of domestic garbage in cities at home and abroad: according to the composition and output of garbage, combined with the resource utilization and treatment methods of local garbage. Germany is generally divided into paper, glass, metal, plastic and so on. Australia is generally divided into compostable garbage, recyclable garbage and non-recyclable garbage; Japan is generally divided into combustible garbage, nonflammable garbage, and so on.

Domestic waste in China can be generally divided into four categories: recyclable waste, kitchen waste, harmful waste and other wastes. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting.

1. Recyclable garbage includes paper, metal, plastic, glass, etc. Through comprehensive treatment and recycling, pollution is reduced and resources are saved. 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%.

2. Kitchen waste includes food waste such as leftovers, bones, roots and leaves. After in-situ composting by biotechnology, 0.3 tons of organic fertilizer can be produced per ton.

3. Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.

4. Other wastes include bricks and tiles, waste residue, toilet waste paper and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
