1. What are the tips of garbage classification

Benefits of garbage classification

The benefits of garbage classification are obvious. After sorting, the garbage is sent to the factory instead of the 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, the waste batteries called "mini-killers" are all known to contain heavy metals such as mercury or cadmium. If these heavy metals are left underground, they will easily leach into the groundwater through rainwater, which will cause serious persecution to water resources and land. However, waste batteries contain a variety of useful metal minerals, and the value of recycling 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 to put button cell and others in separately. Another example is biological waste such as leftover lettuce, eggshell peel, kitchen garbage such as picking cabbage leaves, but they can be used to make good organic fertilizers. Like this big nano-dream biological waste processor in Huaibaishu 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, the vegetables grown with them are safe and healthy, and they are quite popular in supermarkets. Biological waste usually accounts for 41% of the total waste. If all of them can be turned into organic fertilizer, it will not only save land used as landfill, but also save vehicles and energy for transporting them, and prevent them from breeding mosquitoes, flies and bacteria.

therefore, garbage sorting has many benefits.

Introduce environmentally-friendly classified trash cans

Generally speaking, common environmentally-friendly classified trash cans are divided into green, yellow and red.

the green ones are for putting recyclable garbage, such as paper, plastic, rubber, metal, glass, etc.

yellow is non-recyclable garbage, non-recyclable garbage: mainly kitchen garbage, including peels, vegetable peels, leftovers, etc.

Red is toxic to harmful waste and toxic to harmful waste: batteries, fluorescent tubes, mercury thermometers,

paint buckets, medicines, cosmetics, etc.

2. Common sense of garbage classification

From the methods of classifying domestic garbage in cities 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 and so on; 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 waste in China can be generally divided into four categories: recyclable waste, kitchen waste, harmful waste and other wastes. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration for power generation, composting and resource return.

recyclable garbage

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

Kitchen waste

includes food wastes such as leftovers, bones, roots, leaves and peels

harmful waste

includes waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.

other wastes

include bricks and tiles, dregs, toilet waste paper, paper towels and other wastes that are difficult to recycle, and sanitary landfill can effectively reduce the pollution to groundwater, surface water, soil and air.

3. Little knowledge of garbage classification

Knowledge of garbage classification

In Germany, littering is very particular. If you accidentally throw it in the wrong place, the whole community may suffer. Since 2112, I have been studying in Germany, studying for a master's degree in environmental engineering. After school, I also worked in a garbage recycling company, and I personally felt that Germans attach importance to environmental protection.

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

The recycling rate of garbage in Germany ranks first in Europe, and the garbage sorting 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 bins, and for the convenience of collection, bins 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 it.

There are few open-type garbage bins, and they are basically slide-type designs. When you throw garbage, you should push the lid away, and the lid will automatically return to its original position after you let go. This has two advantages: first, it prevents rainwater from falling into the box and turns the garbage bin into a water tank. Secondly, odor escape can be reduced.

Trash cans on the street are usually covered with plastic bags in yellow and blue. The former collects recyclable garbage such as paper packaging, while the latter accommodates domestic garbage such as peels.

trash cans in the kitchen are generally required to be covered with blue plastic bags, and the leftovers, peels, fruit scraps and so on are usually left here. When the bag is full, tie a knot and carry it to a designated place outside the house. The cleaner will know how to sort the plastic bag as soon as he sees its color.

For organic waste (food, etc.), Germany usually incinerates or buries it, but since 2115, the EU has banned the 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 garbage bin, which is the place where paper is thrown, and unwanted waste paper, newspapers, magazines, books and so on are thrown there.

however, it should be noted that cartons and cartons should not be thrown in. Because they belong to recyclable packaging, they should be thrown into special yellow plastic bags. 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 from the nearest post office and supermarket. Other recyclable packaging, such as cans, plastic boxes, etc., can be put in this bag as long as the recyclable logo is printed on the material.

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

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

Most Germans support Germany's complicated garbage sorting. A friend of mine studied 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 in China, he mixed up the garbage and threw it out. One day, he saw the dormitory administrator wearing gloves to open his discarded garbage bags and reclassify them, which shocked him and made him very ashamed.

if you don't follow these rules, trouble will come to you. Once, I worked in a garbage recycling company and followed my colleagues to a residential area. A German colleague opened a yellow plastic bag indicating recyclability and found a large group of moldy flour in it. Because the flour was too heavy, it broke the plastic bag and spilled it all over the floor. According to regulations, the flour should be packed in a blue bag. Soon, the staff posted a warning sheet at the door of the community, with the following effect: someone in your community littered and made a mistake. Now we issue the first warning. If we do it again, we won't come again.

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

The wages of cleaning workers in Germany are generally 12 Euros per hour, which is about 3,111 Euros per month, which is not lower than that of white-collar workers in offices. (Source/Urban Express)

4. Information on classification of green and environmentally friendly garbage

Nowadays, domestic garbage in China can be generally divided into four categories: recyclable garbage, kitchen waste, 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: it mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, paper boxes, etc., but 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 various glass bottles, broken glass pieces, mirrors, light bulbs, thermos flask, etc. Metal objects: mainly include cans, cans, toothpaste skins, etc.

cloth: mainly includes discarded clothes, tablecloths, washcloths, schoolbags, shoes, etc. Comprehensive treatment and recycling can reduce pollution and save resources.

If every 1 tons of waste paper is recycled, 851 kilograms of paper can be made, saving 311 kilograms of wood and reducing pollution by 74% compared with the same amount of production; 1.7 tons of secondary raw materials can be obtained for every 1 tons of recycled plastic beverage bottles; 1.9 tons of steel can be refined for every 1 tons of waste steel recovered, which saves 47% cost, reduces 75% air pollution and 97% water pollution and solid waste compared with ore smelting. 2. Kitchen garbage includes food wastes such as leftovers, bones, roots and leaves, etc. After being composted in situ by biotechnology, 1.3 tons of organic fertilizer can be produced per ton.

3. harmful waste includes waste batteries, waste fluorescent tubes, waste water silver thermometers and expired drugs, which need special safety treatment. 4. Other wastes include bricks and tiles, waste residue, toilet waste paper and other wastes that are difficult to recycle except the above-mentioned kinds of wastes. Sanitary landfill can effectively reduce the pollution to groundwater, surface water, soil and air.

5. Little knowledge of garbage sorting: Where did the garbage go after sorting?

After putting Mr. Cat's intelligent garbage recycling equipment into use, we will initially sort the recyclables and transport them to the sorting center for sorting and packaging, and after accumulating a certain amount, they will be uniformly docked to renewable resource recycling enterprises for recycling; Kitchen waste realizes full green in-situ transformation; Other garbage still enters the existing sanitation transfer treatment system and is treated by incineration or landfill; Harmful waste will transport it to the temporary storage point in harmful waste to ensure that it meets the relevant requirements of the environmental protection department. Harmful waste in each community is collected 1 times a week and transported to the temporary storage point in harmful waste for subsequent transportation to qualified terminal processing units.

6. Knowledge of garbage classification

Japan usually divides garbage into four categories:

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

2 combustible resource waste, including newspapers (including leaflets and advertising paper), cartons, cartons, magazines (including books and brochures), old fabrics (including blankets, cotton white shirts and cotton sheets) and cartons for milk and drinks.

3 incombustible resource garbage includes beverage bottles (aluminum cans and tin cans), brown bottles, colorless transparent bottles and bottles that can be directly reused.

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

Domestic garbage can generally be divided into four categories: recyclable garbage, kitchen waste, harmful waste and other garbage. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting.

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, paper boxes, etc., but 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 flask, etc. Metal objects: mainly include cans, cans, toothpaste skins, etc. Cloth: mainly includes discarded clothes, tablecloths, washcloths, schoolbags, shoes, etc. For example, every 1 tons of waste paper can be recycled to make 851 kilograms of paper, saving 311 kilograms of wood and reducing pollution by 74% compared with the same amount of production; 1.7 tons of secondary raw materials can be obtained for every 1 tons of recycled plastic beverage bottles; 1.9 tons of steel can be refined for every 1 tons of waste steel recovered, which saves 47% of the cost compared with ore smelting, and reduces harmful waste, including 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.

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

air pollution is 75%, reducing water pollution and solid waste by 97%.

The kitchen waste includes food wastes such as leftovers, bones, vegetable roots and leaves, etc. After being composted in situ by biotechnology, 1.3 tons of organic fertilizer can be produced per ton.
