Primary classification: recyclable, harmful waste, mass garbage, compostable garbage, other garbage and combustible garbage.
Secondary classification: fabric, bottles and cans, kitchen garbage, batteries, paper, plastic, metal and glass.
Domestic garbage can generally be divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage.
Recyclable garbage: waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cartons and so on. It is worth noting that paper towels and toilet paper are not recyclable because of their strong water solubility.
Plastics mainly include all kinds of plastic bags, plastic packaging materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles and so on.
Glass mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on.
Metal objects mainly include cans, cans, toothpaste skins and so on.
Cloth mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.
Kitchen waste: food waste such as leftovers, bones, roots and leaves.
Hazardous wastes: waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.
Other garbage: bricks and tiles, muck, toilet waste paper and other wastes that are difficult to recycle.
Question 2: How to classify garbage? Recyclable waste
It mainly includes waste paper, plastic, glass, metal, cloth and so on. 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 leftovers, bones, roots, leaves, peels and other food wastes, can produce 0.3 tons of organic fertilizer per ton by in-situ composting with biotechnology.
hazardous waste
Including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.
other waste
Brick and tile ceramics, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle. According to the characteristics of garbage, it is usually treated by incineration or landfill.
Question 3: What kinds of domestic garbage are there? Generally speaking, domestic garbage can be divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting.
Recyclable garbage includes paper, metal, plastic, glass, etc. Through comprehensive treatment and recycling, pollution can be reduced and resources can be 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%.
Kitchen waste, including food waste such as leftovers, bones, roots and leaves, can be composted in situ by biotechnology, and 0.3 tons of organic fertilizer can be produced per ton.
Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.
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.

Question 4: According to CJJ/T 102-2004 Classification and Evaluation Standard of Municipal Domestic Waste, how should domestic waste be classified?
Question 5: Excuse me: What kinds of domestic garbage can be divided into? Primary classification: recyclable, harmful waste, mass garbage, compostable garbage, other garbage and combustible garbage. Secondary classification: Domestic wastes such as fabrics, bottles and cans, kitchen waste, batteries, paper, plastics, metals and glass can be generally divided into four categories: recyclable waste, kitchen waste, harmful waste and other wastes. Recyclable garbage: waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cartons and so on. It is worth noting that paper towels and toilet paper are not recyclable because of their strong water solubility. Plastics mainly include all kinds of plastic bags, plastic packaging materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles and so on. Glass mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects mainly include cans, cans, toothpaste skins and so on. Cloth mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Kitchen waste: food waste such as leftovers, bones, roots and leaves. Hazardous wastes: waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment. Other garbage: refractory wastes such as brick and tile ceramics, muck and toilet waste paper. I study environmental protection. This calculation should be very detailed. No, I hope the answer will be useful to you in the book Solid Waste Control Engineering.
Question 6: How to divide domestic waste into recyclable and non-recyclable?
Question 7: How can garbage be classified as recyclable garbage?
It mainly includes waste paper, plastic, glass, metal, cloth and so on.

Question 8: How to classify rural domestic garbage With the development of society and the continuous improvement of economic level, people produce more and more domestic garbage, especially rural domestic garbage. It mainly includes batteries, light bulbs, pesticide bottles, paint buckets, waste water silver thermometers, expired drugs, ink cartridges, selenium drums, non-degradable plastic products (ultra-thin plastic bags, agricultural films) and so on. With the development of rural and urban-rural integration, the amount of this kind of garbage is increasing year by year. This kind of garbage has the greatest potential harm to the rural ecological environment and needs special safety treatment. For example, button cell contains toxic heavy metal mercury; Rechargeable batteries contain harmful heavy metal cadmium; Dry batteries contain mercury, lead, acid and alkali substances and other substances harmful to the environment. However, waste plastic products are difficult to decompose, destroying soil and reducing plant growth by 30%; Groundwater may be polluted after landfill; Incineration will produce harmful gases. How to treat rural domestic garbage to be truly harmless? What about the home where we live? We can't help worrying. Therefore, the first problem to be solved is to carry out popular science propaganda and enhance farmers' awareness of environmental protection. Because it is very important to shape the social participation consciousness of social individuals and even social organizations through effective environmental education. Doing a good job in rural domestic garbage disposal requires the active participation and cooperation of rural residents, and environmental protection departments, news media and teaching units need to go to the countryside to publicize and popularize environmental protection knowledge. We should be good at combining and using World Environment Day, Earth Day and National Patriotic Health Month. Hanging environmental protection propaganda slogans in public places, organizing cadres, the masses and students to carry out environmental sanitation cleaning, using radio, television and other media for publicity, holding mass environmental protection knowledge contests and other activities to attract the active participation of the general public and gradually improve residents' environmental awareness. The publicity and education of environmental awareness should start with the details that are closest to farmers' lives, so that environmental knowledge can be in "zero distance" contact with them in the form of small moves and tricks, so as to narrow the distance between knowledge and life, eliminate the plot of farmers' conflict and improve the publicity effect. The treatment technology of "fast, harmless, non-surplus, resource-based and industrialized" is referred to as "LJ five-oriented" treatment technology. Technical settings: 1, uniform feeding of municipal solid waste, automatic sorting system for large-size garbage; 2. Bagged garbage automatic bag breaking and organic matter automatic crushing system; 3. Fully enclosed mechanized sorting system for urban solid waste; 4. Organic hydrolysis water thermal oxidation fertilizer production system; 5. Inorganic building material system; 5. Plastic refining or granulating system; 6. Non-recoverable combustible pyrolysis gasification and waste heat utilization system; 7. Waste gas treatment system; 8. Eight treatment systems, such as sewage treatment system, are integrated into one, which can treat municipal solid waste generated in various places on the same day and produce products on the same day. This technology has been successfully applied to waste treatment plants in Guangdong, Zhejiang, Yunnan, Guizhou, Hebei, Liaoning, Shanxi and other places, and has achieved obvious economic and social benefits in various places, realizing the recycling and industrialization of waste treatment to the maximum extent. Experts agree that this technology treats waste with waste, which meets the requirements of circular economy development and represents the development direction of garbage disposal in China.
