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 still work in a garbage recycling company. Personally, I think 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 kinds of garbage are collected by different bins. In order to facilitate the collection, bins are often placed in different places. After finding 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 dustbins, and they are basically of sliding design. When you throw garbage, you should push the lid away, and the lid will automatically return to its original position after it is released. This has two advantages: first, it can prevent rainwater from falling into the box and turn the garbage bin 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 and fruit scraps. Usually stay here. When the bag is full, tie a knot and take it to the designated place outside the house. As soon as the cleaners see the color of plastic bags, they know 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 for power generation or heating. There is usually a green box next to the organic trash can, which is the place to throw paper. Unwanted waste paper, newspapers, magazines and books are all thrown there.

But it should be noted that cartons and cartons cannot 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 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 a box for collecting used batteries. Glass bottles and glass bottles are thrown into different dustbins according to their colors. Usually, the bins of glass products are in groups of three, and there are striking color signs on the boxes: brown, green, transparent and colorless to remind 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 he lived in a student apartment when he first arrived in Germany. Because he didn't have this habit in China, he mixed up the rubbish and threw it out. One day, he was shocked and ashamed to see the dormitory administrator wearing gloves to open his discarded garbage bags and classify them again.

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 blue bags. Soon, the staff posted a warning sign at the gate of the community, which read: 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 will be extra careful.

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

2. What are the tips for garbage sorting?

Benefits of garbage sorting

The benefits of garbage sorting are obvious. Garbage is sorted and 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, waste batteries called "mini killers" all contain heavy metals such as mercury or cadmium. If these heavy metals are left underground, they can easily penetrate into groundwater through rainwater, causing 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 yellow bucket, which can be used to put button cell and other batteries separately. Another example is biological waste, such as leftover lettuce, eggshell skin, picking cabbage leaves and other kitchen wastes, but they can be used to make good organic fertilizers. This big nano-dream biological waste processor in the community of Huaibai Tree can dry and crush biological waste and make it into 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 they can all be turned into organic fertilizers, it can not only save landfill land, but also save transportation vehicles and energy, and prevent the breeding of mosquitoes, flies and bacteria.

Therefore, garbage sorting has many advantages.

Introduce environmentally-friendly classified trash cans.

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

Green is used to put recyclable garbage, such as paper, plastic, rubber, metal and glass.

Yellow is non-recyclable garbage, non-recyclable garbage: mainly kitchen waste, including peels and vegetables.

Skin, leftovers, etc.

Red toxic harmful waste toxic harmful waste: batteries, fluorescent tubes, mercury thermometers,

Paint bucket, medicine, cosmetics, etc.

3. The speech on garbage classification is about 150 words.

One day, I was walking by the roadside and saw a little boy standing beside two trash cans with a broken plastic cup in his hand. I used to look, and it turned out that the two trash cans contained "recyclable garbage" and "non-recyclable garbage" respectively. I guess he's thinking: are plastic cups recyclable or non-recyclable? Later, regardless of the willy-nilly, he threw the plastic cup into the bucket of non-recyclable garbage. I witnessed everything quietly, and then walked away quietly.

After I got home, I checked the computer immediately. It was found that plastic cups originally belonged to recyclable garbage. But the boy mistook the plastic cup for non-recyclable garbage, found the wrong home for the plastic bottle, and mistaken his mother. In fact, in life, is this phenomenon still rare? Because people know too little about recyclable and non-recyclable garbage, they often confuse the types of garbage when throwing garbage. In the past, people always advocated "Don't litter". Nowadays, this bad phenomenon has been obviously improved, but another big problem has come: littering should also be classified. But people always don't pay enough attention to this bad phenomenon, which leads to more and more such phenomena like viruses. What should I do? I searched online for the benefits of garbage sorting. Garbage classification can not only make good use of favorable resources, but also play an important role in the environment. But in life, there are always some people who are afraid of trouble and often classify garbage, which will have a bad influence. Therefore, I hope everyone can attach importance to garbage classification, implement garbage classification and correctly classify garbage. Here, I would like to put forward several initiatives:

1。 Recommend families and regions that have not yet implemented waste sorting to practice waste sorting; Households and regions that have implemented garbage classification should try their best to classify garbage correctly.

2。 I hope everyone can learn more about the benefits of garbage sorting online.

3。 I hope you can strengthen your understanding of "recyclable garbage" and "non-recyclable garbage" and learn more about these two different types of garbage.

4。 When you meet some "people who don't know what kind of garbage belongs to", it can help them distinguish garbage correctly.

5。 I hope more people will join us and call on everyone to "implement garbage sorting and create a beautiful home together".

In order to create a beautiful home, we advocate more people to join the "garbage sorting" team, add a touch of beauty to the home and add some environmental protection to the earth. I believe that with our joint efforts, the future will be full of sunshine and hope and become a blue sky.

4. Common sense of garbage classification

Judging from the classification methods of 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, 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 waste, 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 recycling.

Recyclable waste

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

kitchen waste

Include food waste such as leftovers, bones, roots, leaves and peels.

hazardous waste

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

other waste

Including bricks and tiles, waste residue, 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.

5. Garbage classification summary is 200 to 300 words.

Sorting garbage My family life is getting better every day, and there are more and more domestic garbage. There are several bags of miscellaneous domestic garbage every day.

I think this must have added a lot of burden to sanitation workers. In order to reduce the burden of sanitation workers, I classify domestic garbage before taking out the garbage. Once, I cleaned out cans, bottles and waste paper and put them in three cartons respectively. My mother saw it and asked strangely, "What are you doing?" I told my mother: "I'm sorting garbage, and some of it can be recycled, which can not only support national construction, but also reduce pollution and increase income!" " Mother said happily, "it is everyone's responsibility to protect the environment!" " "It's very thoughtful of you, son. That's a good idea.

! "After listening to my mother's praise, I was overjoyed.

6. Ask for some knowledge of garbage classification

Recyclable waste

It 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, water 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, washcloths, 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 compared with the same output, the pollution is reduced by 74%; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every 65,438+0 tons of scrap steel can be recycled into 0.9 tons of steel, which saves 47% of the cost, reduces 75% of air pollution and 97% of water pollution and solid waste compared with ore smelting.

kitchen waste

Including leftovers, bones, roots, leaves, peels and other food wastes, can produce 0.3 tons of organic fertilizer per ton through in-situ composting by 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.

7. Ask to write an article about the benefits of garbage sorting. 150 is enough ~ urgent.

Reduce the occupation of land. 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 60%. Reduce environmental pollution. Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human beings. Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death.

Therefore, recycling can reduce the harm. Turning waste into treasure China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, which account for 8- 15% of domestic waste.

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 production waste can be recycled, so we should cherish this small-scale and large-scale resource.

Can also be used as a pencil case, which is environmentally friendly and saves resources.
