"Three modernizations and four modernizations" refers to the reduction, recycling and harmlessness of domestic garbage, classified delivery, classified collection and transportation, classified utilization and classified disposal.

By constantly improving the collection, transportation and disposal system of recyclables, hazardous wastes and other garbage, the reduction, recycling and harmless treatment of urban domestic garbage will be realized.

The sanitation department should increase the investment and update of facilities and equipment, ensure that other garbage collection vehicles are in place, and put an end to mixed transportation and mixed treatment of classified garbage; Environmental protection departments should take the lead in collecting, transporting and disposing toxic and hazardous wastes regularly.

Streets should guide communities to do a good job in recycling recyclable garbage, actively explore low-value recyclable material systems such as glass and Tetra Pak packaging, and improve the promotion of panda old clothes recycling barrels.

The financial department should do a good job in funding to ensure the long-term promotion of garbage sorting. All relevant units should take effective measures to create a social atmosphere in which the whole people know and participate, and mobilize the whole city to participate in the garbage sorting work.

Extended data:

Domestic garbage can generally be divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. 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 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 time 1 ton plastic beverage bottle is recycled, 0.7 tons of secondary raw materials can be obtained.

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 wastes, including food wastes such as leftovers, bones, roots and leaves, are composted 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, 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.

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. Pupils with common sense of garbage classification

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 for power generation, composting and resource reuse. (1) Recyclable garbage: It mainly includes five categories: waste paper, plastic, glass, metal and cloth.

1. Waste paper: it mainly includes newspapers, periodicals, books, all kinds of 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. 2. Plastics: mainly including various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste tubes, etc.

3. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. 4. Metal objects: mainly include cans and cans.

5. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Through the comprehensive treatment and recovery of recyclable garbage, 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%.

Recyclable refers to articles that can be used as raw materials for production after recycling or finishing, mainly including: paper, plastic, glass, metal, fabric, electronic waste and so on. According to the actual situation of our city, kitchen waste can be divided into perishable food waste (leftovers, animal manure, discarded food, etc.). ) produced in households and garbage (food residue, residual liquid, waste oil, etc. ) catering service units (restaurants, restaurants, hotels and other catering enterprises and canteens) are produced in food processing, catering services, catering and other activities.

Toxic and hazardous wastes include waste batteries, electric plates, light bulbs, lamps, paints, household products, mercury thermometers and expired drugs. Other garbage refers to garbage other than the above recyclables, kitchen garbage and toxic and harmful wastes, mainly including paper towels, cabbage leaves, plastic wrap (bags), food bags, packaging bags, melon skins and shells, cigarette butts, etc.

5. Common sense of garbage classification

Judging from the classification methods of municipal solid waste at home and abroad, it is generally classified according to the composition and output of garbage, combined with the resource utilization and treatment methods of local garbage.

For example, Germany is generally divided into paper, glass, metal, plastic, etc. 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. 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 for power generation, composting and resource reuse. Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth.

Kitchen waste includes food waste such as leftovers, bones, vegetable roots, leaves and peels. 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.

6. Poor knowledge of garbage classification

Garbage classification knowledge

In Germany, littering is very particular. If you accidentally throw it in the wrong place, the whole community may suffer. Since 2002, I have been studying in Germany for a master's degree in environmental engineering. After school, I also worked in a garbage recycling company. Personally, I feel that Germans attach importance to environmental protection.

It took me a month to figure out how to throw garbage.

Germany's garbage recovery rate ranks first in Europe, and its garbage classification system is also very complicated.

Domestic waste can be divided into five categories: organic waste, recyclable packaging, paper, glass products and batteries. Different garbage is collected by different trash cans. For the convenience of collection, trash cans are often placed in different places. After I found a house in Germany, the first thing I did was to ask my neighbors how to throw garbage correctly. It took me a whole month to fully understand.

There are few open garbage bins, and they are basically slide-type designs. When throwing garbage, push the lid away, and the lid will automatically return to its original position after it is released. This has two advantages: first, prevent rainwater from falling into the box and turn the trash can into a water tank. Secondly, odor escape can be reduced.

Trash cans and plastic bags on the street are generally divided into yellow and blue. The former collects recyclable garbage such as paper packaging, while the latter accommodates domestic garbage such as peels.

The trash can in the kitchen is generally required to be covered with blue plastic bags, leftovers, melon peels, fruit scraps and so on. Usually left here. When the bag is full, tie a knot and carry it to the designated place outside the house. As soon as the cleaner saw the color of plastic bags, he knew how to sort them.

For organic waste (food, etc. ), Germany usually incinerates or buries it, but since 2005, the EU has banned landfill of organic waste. Incineration pollution is small, and heat can be used to generate electricity or heat. There is usually a green box next to the organic trash can, which is where the paper is thrown. Unwanted waste paper, newspapers, magazines, books and so on are thrown there.

However, it should be noted that cartons and cartons cannot be thrown in. Because it belongs to recyclable packaging, it should be thrown into a special yellow plastic bag. China people who have just arrived in Germany often don't know this. This kind of plastic bag with eye-catching recyclable logo can be obtained free of charge at the nearest post office and supermarket. Other recyclable packaging, such as cans, plastic boxes, etc. You can put it in this bag as long as the material is printed with a recyclable sign.

Every supermarket in Germany has boxes for collecting used batteries. Glass bottles and glass bottles are thrown into different bins according to their colors. Usually, the cabinets of glass products are in groups of three, and there are eye-catching color signs on the boxes: brown, green, transparent and colorless, reminding you not to throw them wrong.

If we do it again, we won't come again.

The vast majority of Germans support Germany's complicated garbage classification. A friend of mine is studying in Dresden University. He said that when he first arrived in Germany, he lived in a student apartment. Because he didn't have this habit at home, he mixed up the garbage and threw it out. One day, he saw the dormitory administrator wearing gloves to open his discarded garbage bags for reclassification, which shocked him and made him ashamed.

If you don't follow these rules, trouble will come to you. Once, I worked in a garbage recycling company and went to a community with my colleagues. A German colleague opened a yellow plastic bag marked recyclable and found a large group of moldy flour inside. Because the flour was too heavy, it broke the plastic bag and spilled it all over the floor. According to the regulations, flour should be packed in a blue bag. Soon, the staff posted a warning sign at the gate of the community to the effect that someone in your community littered and made a mistake. Now let's issue the first warning. If we do it again, we won't come again.

According to the Germans, once it happens for the second time, the garbage recycling company will punish the whole community, and the community managers will spend a lot of energy to coordinate, so everyone is extra careful.

The salary of cleaners in Germany is generally 12 euros per hour, about 3,000 euros a month, which is not lower than that of office white-collar workers. (Source/Urban Express)

7. Knowledge of garbage classification

Japan usually divides garbage into four categories:

1 General garbage includes kitchen waste, paper scraps, plants, packaging bags, leather products, containers, glass, tableware, non-resource bottles, rubber, plastics, clothes except cotton and white shirts, and wool.

Combustible resource garbage, including newspapers (including leaflets and advertising paper), cartons, cartons, magazines (including books and brochures), old cloth (including blankets, cotton shirts and cotton sheets) and cartons for milk and drinks.

Noncombustible resource waste, including beverage bottles (aluminum cans, tin cans), brown bottles, colorless transparent bottles and bottles that can be directly reused.

Large pieces of garbage that can be crushed include small household appliances (televisions, air conditioners, refrigerators/cabinets, washing machines), metals, furniture, bicycles, ceramics, irregular cans, bedding, straw mats, long-chain objects (hoses, ropes, iron wires, wires, etc.). ).
