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% 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, leaves and peels, 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 2: How to classify garbage? Recyclable waste

Question 3: What is domestic garbage and how to classify it? Domestic garbage can generally 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.
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% of the 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.
Question 4: How to classify garbage? Five-point garbage classification is to classify garbage according to "recyclable" and "non-recyclable", and make it a resource again through classified transportation and recycling.
2. Reasons for garbage classification:
1) Economic aspect: Garbage classification can turn recyclable garbage into treasure and become a new resource that can be reused. For example, the cans we drink are recyclable garbage, and one ton of cans can be melted to form a ton of good aluminum blocks, which can save 20 tons of aluminum ore.
2) Land occupation: Garbage classification is conducive to reducing the consumption of land resources. Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage sorting, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
3) Environmental pollution: littering will cause insects and flies to fly around, and sewage will overflow with stench. Some garbage contains toxic substances such as heavy metals, which seriously pollutes the environment. Reasonable garbage sorting and collection can reduce the amount of garbage treatment. For example:
Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human beings, so recycling can reduce the harm.
3. How to classify garbage:
1) First of all, we should know what is recyclable and what is not.
Recyclable garbage 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. 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. Kitchen waste includes food waste, such as leftovers, bones, roots, leaves and peels, which are composted in situ by biotechnology. Comprehensive treatment and recycling can reduce pollution and save resources.
2) Matters needing attention when throwing garbage:
(1) Before the garbage is classified and put in, the paper should be stacked neatly as far as possible to avoid rubbing;
(2) After the products in the containers are cleaned and put into use, they should be used up as much as possible;
(3) The kitchen waste should be bagged and sealed.
(4) Glass articles should be handled with care to avoid damage.
⑤ Pay attention to cover the trash can after it is put into use, so as to avoid garbage polluting the surrounding environment and breeding mosquitoes and flies.
Question 5: How to classify domestic waste;
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 6: How to do a good job in garbage classification must first understand garbage classification. If you don't know, you can't do it.
Know the correct name of garbage classification. Many people call recyclables recyclable garbage. Since it can be recycled, it's not garbage, is it?
With the above conditions, we can start from different kinds. (Recyclable, harmful waste, other garbage, kitchen garbage)
You can put some classified trash cans at home, start at home, fill them and then pour them into the unified trash can in the community (or other places). If you need money, this can be scrapped.
In fact, if you want to do a good job in garbage sorting, you must be conscious. If not, you can't do it well even if you work hard all your life.
I have some information about garbage classification. Please have a look:
1. Recyclable garbage mainly includes 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. Recyclable materials 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% of the cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%. 2. Kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels, can be composted in situ by biotechnology, and 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, 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. Or: 4. Other wastes include bricks and tiles, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle except the above-mentioned types of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
Most of the garbage disposal methods still stay in the traditional stacking and landfill mode, covering tens of thousands of acres; Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment. Therefore, classified collection of garbage can reduce the quantity and equipment of garbage disposal, reduce the disposal cost and reduce the consumption of land resources, which has social, economic and ecological benefits. The advantages of garbage sorting treatment are as follows: 1, reducing land occupation: some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%. (12) Reduce environmental pollution: Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body; Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm. 3. Turning waste into treasure: China uses 4 billion plastic snack boxes and 500-700 million instant noodle bowls every year, and waste plastic accounts for 4-7% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
Japanese garbage classification Foreigners who first came to Japan will be deeply impressed by its amazing garbage classification. At first glance, Japan's garbage classification has the following characteristics. First, fine classification and timely recovery. The largest category is combustible, nonflammable, resource, rough and harmful, and it is subdivided into several subprojects, each of which can be subdivided into grandson projects, and so on. Combustible: In short, it is combustible-but ... >>
Question 7: Classification method of garbage According to the industry standard of Classification and Evaluation Standard of Municipal Domestic Waste,
Recyclable:
Refers to the waste suitable for recycling and resource utilization. It mainly includes five categories:
1. paper: writing paper, wrapping paper and other paper products that are not seriously polluted. Such as newspapers, all kinds of wrapping paper, office paper, advertising paper, cartons and so on. ; But paper towels and toilet paper are too water-soluble to be recycled. )
2. Plastics: plastic products such as container plastics and packaging plastics. Such as various plastic bags, plastic bottles, foamed plastics, disposable plastic lunch boxes and tableware, hard plastics, etc.
3. Metals: all kinds of scrap metal products. Such as cans, tin cans, lead toothpaste, waste batteries, etc.
4. Glass: colored and colorless waste glass products; (mainly including all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, etc. )
5. Fabric: old textile clothing and textile products. (Mainly includes discarded clothes, towels, schoolbags, shoes, etc. )
Non-recyclable materials:
Refers to garbage except recyclable garbage, which is generally decomposed under natural conditions, such as skins, leaves, leftovers, flowers, branches and leaves, etc. It also includes cigarette butts (note that cigarette butts must be thrown into special boxes, not directly into non-recyclable boxes), coal cinders, construction waste, paints and pigments. After being abandoned, it has little use value.
Simply put, recyclable is recyclable garbage. Non-recyclable means harmful to the environment and must be treated harmlessly.
Question 8: How to classify garbage into different categories according to the requirements of different disposal methods?
Domestic garbage can generally 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% 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, vegetable roots and leaves. After in-situ composting by biotechnology, 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.
Classification of medical wastes.
Disposable medical devices after use, whether the needles are cut or not, and whether they are contaminated by body fluids, blood and excreta of patients, are all medical wastes and should be managed as medical wastes.
All kinds of glass (disposable plastic) infusion bottles (bags) that are not contaminated by patients' blood, body fluids and excreta after use are not medical wastes and need not be managed according to medical wastes. However, this kind of waste cannot be used for its original purpose when it is recycled, and should be used for other purposes according to the principle of not endangering human health.
Question 9: How is German garbage classified? Each household has four big trash cans.
1. The green bucket is used to hold all food scraps, branches cut from garden trees, grass cut from lawns, and all biological wastes.
2. Blue bucket, used to hold all kinds of old newspaper advertisements and so on.
3. Yellow valve, which contains all food plastic packaging, drinking water bottles, metal cans, daily waste plastics, etc.
4. Black bucket, which contains non-recyclable garbage that does not belong to the above garbage.
In addition, every few blocks, there are special trash cans to recycle all kinds of glass bottles, and discarded furniture and electrical appliances should be collected at the designated time in the city.
