How to classify domestic waste?

Question 1: How to classify domestic waste? The classification of urban domestic waste formulated by the country:

First-level classification: recyclables, hazardous waste, bulky waste, compostable waste, other waste , combustible waste

Secondary classification: fabrics, bottles, kitchen waste, batteries, paper, plastics, metals, glass

Domestic waste can generally be divided into four major categories: Recyclables, food waste, hazardous waste and other waste.

Recyclable garbage: five categories: waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. It is worth noting that paper towels and toilet paper cannot be recycled because they are too water-soluble.

Plastics mainly include various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc.

Glass mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc.

Metal objects mainly include cans, cans, toothpaste wrappers, etc.

Fabrics mainly include discarded clothes, tablecloths, face towels, school bags, shoes, etc.

Kitchen waste: food waste such as leftovers, bones, roots and leaves.

Hazardous waste: waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safe handling.

Other garbage: bricks, ceramics, slag, toilet paper and other waste that are difficult to recycle

Question 2: How to classify garbage? Recyclable waste

Mainly includes five categories: waste paper, plastic, glass, metal and cloth. Waste paper: mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. However, it should be noted that paper towels and toilet paper cannot be recycled because they are too water-soluble. Plastic: mainly includes various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste wrappers, etc. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal objects: mainly include cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, face towels, school bags, shoes, etc. Through comprehensive processing and recycling, pollution can be reduced and resources saved. For example, every ton of waste paper recycled can make 850 kilograms of good paper, save 300 kilograms of wood, and reduce pollution by 74% compared with the same amount of production; every ton of plastic beverage bottles recycled can obtain 0.7 tons of secondary raw materials; every ton of scrap steel recycled can be smelted 0.9 tons of good steel saves 47% of the 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 and leaves, peels, etc., which are composted on-site through biotechnology and can produce 0.3 tons of organic waste per ton. fertilizer.

Hazardous waste

Including waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safe treatment.

Other garbage

Including bricks, ceramics, slag, toilet waste paper, paper towels and other waste that are difficult to recycle in addition to the above categories of garbage. They are usually incinerated according to the characteristics of the garbage. Or disposed of in landfill.

Question 3: What are the types of domestic waste? Domestic waste can generally be divided into four major categories: recyclable waste, kitchen waste, hazardous waste and other waste. Currently commonly used garbage disposal methods include comprehensive utilization, sanitary landfill, incineration and composting.

Recyclable waste includes paper, metal, plastic, glass, etc. Through comprehensive treatment and recycling, pollution can be reduced and resources saved.

For example, every ton of waste paper recycled can make 850 kilograms of good paper, save 300 kilograms of wood, and reduce pollution by 74% compared with the same amount of production; every ton of plastic beverage bottles recycled can obtain 0.7 tons of secondary raw materials; every ton of waste paper recycled Steel can make 0.9 tons of steel, which saves 47% of the cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

Kitchen waste includes food waste such as leftovers, bones, roots and leaves. It can be composted on-site through biotechnology and can produce 0.3 tons of organic fertilizer per ton.

Hazardous waste includes waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safe handling.

Other waste includes bricks, ceramics, slag, toilet paper and other waste that are difficult to recycle in addition to the above categories of waste. Sanitary landfill can effectively reduce the impact on groundwater, surface water, soil and Air pollution.

Question 4: How should domestic waste be classified according to "CJJ/T102-2004 Municipal Domestic Waste Classification" and its evaluation criteria".

Question 5: What types of domestic waste can be classified? Primary classification: recyclables, hazardous waste, bulky waste, compostable waste, other waste, combustible waste Secondary classification: fabrics, bottles, cans, kitchen waste, batteries, paper, plastic, metal, glass Domestic waste General It can be divided into four major categories: recyclable waste, kitchen waste, hazardous waste and other waste. Recyclable garbage: five categories: waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. It is worth noting that paper towels and toilet paper cannot be recycled because they are too water-soluble. Plastics mainly include various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc. Glass mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal objects mainly include cans, cans, toothpaste wrappers, etc. Fabrics mainly include discarded clothes, tablecloths, face towels, school bags, shoes, etc. Kitchen waste: food waste such as leftovers, bones, roots and leaves. Hazardous waste: waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safe handling. Other garbage: Bricks, ceramics, slag, toilet paper and other waste that are difficult to recycle. I am studying environmental protection. This should be considered very detailed. You can find it in the book Solid Waste Control Engineering. I hope the answer will be useful to you

Question 6: How to classify domestic waste into recyclable and non-recyclable materials

Question 7: How to classify garbage into recyclable waste

Mainly includes waste paper and plastic , glass, metal and fabric five categories. Waste paper: mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. However, it should be noted that paper towels and toilet paper cannot be recycled because they are too water-soluble. Plastic: mainly includes various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste wrappers, etc. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal objects: mainly include cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, face towels, school bags, shoes, etc. Through comprehensive processing and recycling, pollution can be reduced and resources saved.

Question 8: How to classify rural domestic waste. With the development of society and the continuous improvement of economic level, people generate more and more domestic waste, among which rural domestic waste is particularly prominent. Mainly including batteries, light bulbs, pesticide bottles, paint buckets, waste mercury thermometers, expired medicines, ink cartridges, toner cartridges, non-degradable plastic products (ultra-thin plastic bags, agricultural film), etc. The amount of this type of garbage is increasing year by year with the development of rural and urban-rural integration. This type of garbage has the greatest potential harm to the rural ecological environment and requires special safe treatment. For example, button batteries contain toxic heavy metal mercury; rechargeable batteries contain harmful heavy metal cadmium; dry batteries contain mercury, lead, acid and alkali substances and other environmentally harmful substances. Waste plastic products are difficult to decompose, destroy soil quality, and reduce plant growth by 30%; they may contaminate groundwater after landfill; and burning can produce harmful gases. How to deal with rural domestic waste so that it can be truly harmless? What about the home we rely on for survival? We can't help but worry. Therefore, carrying out science popularization and enhancing farmers’ environmental awareness are the first issues to be solved. Because it is crucial to shape social participation and environmental awareness of social individuals and even social organizations through effective environmental education. Proper disposal of rural domestic waste requires the active participation and cooperation of rural residents. It requires environmental protection departments, news media and teaching units to go to the countryside to promote and popularize environmental protection knowledge. We should be good at combining and utilizing World Environment Day, World Earth Day, National Patriotic Health Month, etc., hang environmental protection slogans in public places, organize cadres, the masses, and students to carry out environmental sanitation cleaning, and use radio, television and other media to promote , organize environmental protection knowledge competitions and other activities with strong mass participation to attract the active participation of residents and gradually improve residents’ environmental awareness. The publicity and education of environmental protection awareness should start from the details closest to farmers' lives, so that environmental protection knowledge can be "zero-distance" contact with them in the form of small tips and tricks, so as to shorten the distance between knowledge and life, eliminate farmers' resistance, and improve the quality of life. Publicity effect. The "rapid, harmless, residual-free, resource recycling and industrialization of urban domestic waste" treatment technology is referred to as the "LJ Five" treatment technology. This technology set: 1. A system for uniform feeding of municipal solid waste and an automatic sorting system for bulky waste; 2. A system for automatically breaking bags of bagged waste and automatic crushing of organic matter; 3. A fully enclosed, mechanized sorting system for municipal solid waste; 4. Organic hydrolysis hydrothermal oxidation fertilizer system; 5. Inorganic building materials system; 5. Plastic refining or granulation system; 6. Non-recyclable combustibles pyrolysis gasification and waste heat utilization system; 7. Waste gas treatment system; 8. Eight major treatment systems including the sewage treatment system are integrated into one, which can process the municipal waste generated in various places on the same day and produce products on the same day. After this technology was successfully applied to waste treatment plants in Guangdong, Zhejiang, Yunnan, Guizhou, Hebei, Liaoning, Shanxi and other places, obvious economic and social benefits have been achieved in various places, and the resource utilization of waste treatment has been maximized. Regarding industrialization, experts unanimously believe that this technology uses garbage to process garbage, meets the requirements of circular economy development, and represents the development direction of China's garbage disposal industry.
