Question 1: What garbage can be recycled? Why? Present situation and prospect of garbage sorting and recycling in China.

At present, China implements the policy of "sustainable development", and recycling garbage by classification is the best treatment method, which not only saves resources but also protects the environment.

I. Garbage classification

At present, domestic garbage in China can be roughly 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 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 materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc.

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, 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%.

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.

Second, the benefits of garbage sorting

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%.

2. 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 3 billion plastic snack boxes and 500-600 million instant noodle bowls every year, and waste plastic accounts for 3-7% of domestic garbage. 1 ton of waste plastics can recover 600kg of unleaded gasoline and 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.

Third, the status quo of garbage sorting and recycling in China

1, there is not a perfect and effective classification and recycling system.

At present, the disposal method of garbage sorting and recycling has not been widely implemented in China. In many cities, all kinds of garbage are transported to landfills for landfill or incineration. High cost and air pollution. Many provinces and cities do not have perfect recycling plans and routes for classified recycling, and the classification of garbage handled by equipment vehicles is not clear enough. At present, the country only pays attention to the classification of recyclable and non-recyclable garbage, and there are few types and quantities of trash cans on the street. People don't know how to deal with other garbage, which leads to mixed garbage and can't achieve the purpose of classification. No city in China implements garbage sorting, and people have not formed the habit of garbage sorting. Moreover, after garbage sorting, the state has no facilities specifically responsible for this part ... >; & gt

Question 2: What is recyclable garbage and what is non-recyclable garbage? Recyclable refers to the waste suitable for recycling and resource utilization. Mainly includes: 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. ; 2. Plastics: plastic products, such as waste container plastics and packaging plastics. Such as various plastic bags, plastic bottles, foamed plastics, disposable plastic lunch boxes and tableware, hard plastics, etc. 3. Metal: all kinds of fixed metal objects. Such as cans, tin cans, lead toothpaste, waste batteries, etc. 4. Glass: colored and colorless waste glass products; 5. Fabric: old textile clothing and textile products.

Non-recyclable means garbage other than recyclable garbage. Common garbage is easily decomposed under natural conditions, such as skins, leaves, leftovers, flowers, branches and leaves.

Question 3: What are the non-recyclable wastes and how to deal with them? Garbage other than recyclables is basically waste. Such as cigarette butts, chicken feathers, waste electricity, coal cinders, construction waste, paints and pigments, food residues and so on. Toxic garbage, including waste batteries, fluorescent tubes, mercury thermometers, paint cans, medicines, cosmetics, etc.

At present, the disposal methods of non-recyclable garbage in China:

(1) Sanitary landfill treatment:

Fill the garbage into the prepared pit and cover it for compaction, so that it will undergo biological, physical and chemical changes and decompose organic matter, thus achieving the purpose of reduction and harmlessness. However, for a long time, most cities in China have used open-air stacking and natural ditch filling for treatment. Without any protective measures, a large amount of garbage and sewage have infiltrated into the ground from the surface, causing serious pollution to the urban environment and underground water sources. Therefore, this garbage disposal method has been gradually eliminated.

(2) Incineration:

Incineration is a method of putting garbage into a high-temperature furnace to fully oxidize the combustible components in it, and the generated heat is used for power generation and heating. The biggest disadvantage of this method is that dioxin gas will be produced when burning garbage, so only by a series of treatment of toxic and harmful gases produced by incineration can this method achieve the purpose of environmental protection. At the same time, the initial investment of incineration treatment is large, and it will cost about 700-800 million yuan to build an incinerator with a daily garbage treatment capacity of 1 10,000 tons and attached heat energy recovery equipment.

(3) Composting method:

Domestic garbage is piled up, kept at 70℃, stored and fermented, and organic matter is decomposed into inorganic nutrients by using the decomposition ability of microorganisms in garbage. After composting, domestic garbage becomes sanitary and odorless humus. It can not only solve the way out of garbage, but also achieve the purpose of recycling. However, domestic waste compost has a large amount and low nutrient content, so long-term use is easy to cause soil hardening and groundwater deterioration. Therefore, the scale of compost is not easy to be too large.

(4) Resource treatment:

The municipal solid waste is carefully classified, and then appropriate methods are taken according to the different properties of the classified garbage, so that different kinds of garbage can be utilized, so as to truly reduce, harmlessly and recycle the garbage.

Question 4: How many kinds of garbage are there? What are these kinds? What rubbish do they mainly recycle? Recyclable waste

Recyclable garbage is recyclable garbage. Pappe, cardboard, glass, plastic, metal and Kunststoffen can be reused themselves, or the materials can be recycled. Newspapers, magazines, advertisements and other clean paper related to these materials can be recycled. In addition, the green label (GrünenPunkt) on the package belongs to the DualeSystem to be paid, and also belongs to recyclable garbage.

Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth.

Waste paper: mainly including newspapers, periodicals, books, various wrapping papers, etc. However, pay attention to paper towels and

Waste sorting toilet paper is not recyclable because of its strong water solubility.

Plastics: mainly including plastic barrels, pots, bottles and plastic clothes hangers.

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 waste clothes, tablecloths, towels, 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 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%.

Folding kitchen garbage

Including food waste, such as leftovers, bones, roots, leaves, peels, etc. Through in-situ composting by biotechnology, 0.6-0.7 tons of organic fertilizer can be produced per ton.

Fold other rubbish

Mainly divided into medical waste and dry waste.

Dry garbage: garbage bags, discarded napkins, diapers, clean lime soil, heavily polluted paper, plastic bags, etc.

Medical waste: waste containing virus, such as cotton swabs with blood and scalpels. This kind of garbage needs special treatment and can only be buried after disinfection.

Folding toxic and hazardous waste

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, household appliances, expired drugs, expired cosmetics, etc. If the battery burns, it will hurt innocent people after explosion; Fluorescent tubes and bulbs, like the above batteries, radiate more; Mercury is more dangerous, it is a toxic substance ... so these wastes are generally recycled separately or specially landfilled.

Question 5: What garbage can be recycled? I. Recyclable garbage

Mainly includes waste paper, plastic, glass, metal and fabric:

Waste paper: writing paper, wrapping paper and other paper products with no serious pollution, including newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cartons, etc. Tissue paper and toilet paper cannot be recycled because of their strong water solubility.

Plastics: plastic products such as waste container plastics and packaging plastics, including various plastic bags, plastic packaging materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste tubes, etc.

Glass: Colored and colorless waste glass products, including all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc.

Metal: all kinds of scrap metal items, including cans and tin cans.

Fabric: old textile clothing and textile products, including discarded clothes, sheets, curtains, tablecloths, towels, schoolbags, cloth shoes, etc.

Second, kitchen garbage.

Including peels, leaves, leftovers, after-dinner garbage, flowers and leaves, etc.

Third, toxic and hazardous waste.

Including paint pigments, waste lamps, waste water silver thermometers, expired drugs, etc.

Fourth, other rubbish.

Including brick and tile ceramics, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle except the above-mentioned types of garbage.

Question 6: What are recyclable garbage and non-recyclable garbage? It should be said that if it is recycled and reprocessed, it can become some production raw materials or articles that can be reused after finishing, such as paper, glass, metal, plastic, textiles, rubber products and so on. Specifically, non-recyclable garbage such as waste newspapers, wine bottles, cans and old clothes should be non-recyclable garbage such as leftovers and peels. Food residues and other things that need attention are: waste batteries, fluorescent tubes, mercury thermometers, paint buckets, cosmetics and so on. These are toxic wastes and need special treatment.

Question 7: What kind of garbage is not recyclable? What garbage is recyclable? Unrecoverable garbage includes cigarette butts, peels, vegetable leaves, chicken feathers, cinders, construction waste, paints and pigments, food residues, etc.

Attention should be paid to, such as waste batteries, fluorescent tubes, mercury thermometers, paint cans, medicines, cosmetics and so on. These are all toxic wastes and need special treatment.

Recyclable:

1。 Waste paper: newspapers, book paper, wrapping paper, office paper, advertising paper, cartons, etc. However, it should be noted that paper towels and toilet paper are too water-soluble to be recycled. We all know that waste paper can be bought, and people often come to our community to collect waste paper. )2。 Plastics: all kinds of plastic bags, plastic foams, plastic packaging, disposable plastic lunch boxes and tableware, hard plastics, etc. Many plastic products used in our life are actually reprocessed from waste plastics. )3。 Glass: glass bottles and broken glass pieces, mirrors, light bulbs, thermos bottles, etc. ; Most bottles like alcohol in life are recycled. Metals: cans, tin cans, etc. The boy still remembers that there was a spoon at home that was recast with these scrap aluminum. Fabric: old textile clothing and textile products, waste clothes, tablecloths, towels, schoolbags, etc.

Question 8: What garbage is not recyclable? Non-recyclable garbage includes cigarette butts, peels, vegetable leaves, chicken feathers, cinders, construction waste, paints and pigments, food residues, etc.

Attention should be paid to, such as waste batteries, fluorescent tubes, mercury thermometers, paint cans, medicines, cosmetics and so on. These are all toxic wastes and need special treatment.

Question 9: What are the recyclable wastes? What are the non-recyclable wastes? Recyclable resources in life mainly include:

(1) Waste paper: newspapers, book paper, wrapping paper, office paper, advertising paper, cartons, etc. Note that paper towels and toilet paper are too water-soluble to be recycled.

(2) 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.

(3) Glass: glass bottles and broken glass pieces, mirrors, light bulbs, thermos bottles, etc.

(4) Metals: cans, tin cans, toothpaste skins, etc.

(5) Cloth: mainly includes discarded clothes, tablecloths, towels, cloth bags, etc.

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%.

Except for the garbage recovered by Chu, it is basically waste. Such as cigarette butts, chicken feathers, waste electricity, coal cinders, construction waste, paints and pigments, food residues and so on.

Toxic garbage, including waste batteries, fluorescent tubes, mercury thermometers, paint cans, medicines, cosmetics, etc.

Garbage is a misplaced treasure. Recycling garbage not only beautifies the environment, but also saves the exploitation of new resources, thus fundamentally reducing garbage. It's easy to participate in environmental protection. Let's start with the little things around us and start with the correct dumping of garbage.

Question 10: What are the three kinds of classified garbage, recyclable and non-recyclable? Hazardous wastes (red barrels) such as waste batteries, waste fluorescent tubes, mercury thermometers, waste paints, expired drugs, etc. Non-recyclable garbage (yellow bucket) garbage that is easily decomposed under natural conditions, such as skins, vegetable skins, leftovers, etc. Recyclable garbage such as waste paper, plastic, metal, glass and cloth (blue bucket). Among them, waste paper includes: newspapers, various wrapping papers, office paper, advertising paper, large and small cartons, etc. Waste plastics include: all kinds of plastic bags, plastic bottles, plastic packaging, foamed plastics, disposable plastic lunch boxes and tableware, hard plastics, etc. Scrap metal includes: cans, tin cans, lead toothpaste skin, etc.
