Garbage sorting knowledge classic words

1. What are some tips on garbage classification?

The benefits of garbage classification

The benefits of garbage classification are obvious. After the garbage is sorted, it 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, waste batteries are called "micro-killers". It is well known that batteries in daily life contain heavy metals such as mercury or cadmium. If these heavy metals are left underground, they will easily enter the groundwater through rainwater leaching and have a negative impact on water resources. and land causing severe persecution. However, waste batteries contain a variety of useful metal minerals, and their recycling value is very high. Because of the serious hazards and special recycling value of waste batteries, many countries strictly prohibit them from being mixed with garbage. Japanese communities have special yellow buckets to put button batteries and other materials separately. Another example is biological waste such as leftover lettuce, eggshell peels, vegetable leaves and other kitchen waste, which can be used to make good organic fertilizers. For example, the Da Nameng biological waste treatment machine in Huaibaishu Community can dry and crush biological waste to make efficient organic fertilizer. Residents can use it to grow flowers and grass. The vegetables grown using them are safer and healthier than food grown with chemical fertilizers, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste. If they can be turned into organic fertilizer, it will not only save land used for landfills, but also save vehicles and energy to transport them, and prevent them from breeding mosquitoes, flies and bacteria.

Therefore, there are many benefits to garbage classification.

2. Some common sense about garbage classification

Judging from the methods of classifying domestic garbage in various cities at home and abroad, they are generally based on the composition of the garbage. The composition and production volume are classified based on the resource utilization and treatment methods of local waste.

For example, Germany is generally divided into paper, glass, metal, plastic, etc.; Australia is generally divided into compostable garbage, recyclable garbage, non-recyclable garbage; Japan is generally divided into combustible garbage, non-burnable garbage, etc. . Today, domestic waste in China can generally be divided into four major categories: recyclable waste, kitchen waste, hazardous waste and other waste.

Currently, the commonly used garbage disposal methods include: comprehensive utilization, sanitary landfill, incineration for power generation, composting, and resource return. Recyclable waste mainly includes five categories: waste paper, plastic, glass, metal and cloth.

Kitchen waste includes food waste such as leftovers, bones, roots and leaves, peels, etc. Hazardous waste includes waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safety deal with. Other garbage includes bricks, ceramics, slag, toilet paper, paper towels and other waste that are difficult to recycle in addition to the above categories of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

3. Garbage classification jingle

According to Shanghai’s official garbage classification regulations, Shanghai’s domestic waste is divided into four types: hazardous waste, recyclables, dry waste, and wet waste. .

Beijing’s waste classification is also divided into four types: hazardous waste, recyclables, kitchen waste, and other waste.

Garbage classification - Figure 1

In fact, the four categories in Beijing and Shanghai are the same. The kitchen waste in Beijing is Shanghai’s wet waste, and the other garbage in Beijing is Shanghai’s. Dry garbage has different names, but the actual types of garbage are the same.

1. Recyclable garbage: put glass and metal in blue buckets and recycle them into treasures.

Recyclable garbage refers to waste paper, waste plastics, waste glass products, waste metal, waste fabrics and other domestic wastes that are suitable for recovery and recyclability.

2. Hazardous waste: Battery waste chemicals are harmful, and lamp paint is put into red buckets.

Hazardous waste refers to waste batteries, waste light tubes, waste medicines, waste paint and their containers, etc. that pose direct or potential danger to human health or the natural environment.

3. Wet garbage: Kitchen leftovers, melon peels, etc. should all be transferred to wet garbage.

Wet garbage is perishable garbage, which refers to biomass domestic waste such as food waste, leftovers, expired food, melon peels and cores, flowers and green plants, traditional Chinese medicine residues, etc.

4. Dry garbage: hairy diapers, cigarette butts, harmless and useless in the ash bucket.

Dry garbage refers to other garbage, which refers to other domestic waste other than recyclables, hazardous garbage, and wet garbage.

4. Little knowledge about garbage classification

Knowledge about garbage classification

In Germany, throwing away garbage is very particular. If you accidentally throw it in the wrong place, the entire community may suffer. I have been studying in Germany since 2002, pursuing a master's degree in environmental engineering. After school, I also worked in a garbage recycling company, and I personally felt the importance that Germans attach to environmental protection.

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

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

Domestic waste can be divided into 5 major categories: organic waste, recyclable packaging, paper, glass products and batteries. Different garbage is collected by different garbage bins, and in order to facilitate collection, the garbage bins are often placed in different places. The first thing I did after finding a house in Germany was to ask my neighbors for advice on how to properly throw away garbage. It took me a whole month to fully understand it.

Trash cans are rarely open-top, and most are of sliding-lid design. When throwing away garbage, push the lid open with force. After letting go, the lid will automatically return to its original position. This has two benefits: First, it prevents rainwater from falling into the box and turns the trash can into a water tank. Secondly, it can reduce the odor escape.

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

The trash can in the kitchen is generally required to be covered with a blue plastic bag. The usual leftover meals, melon peels and fruit scraps, etc. are thrown here. When the bag is full, tie it into a knot and carry it to a designated place outside the house. The cleaning staff will know how to sort and dispose of the plastic bag just by looking at its color.

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

However, it should be noted that cartons and cartons cannot be thrown in.

Because they are recyclable packaging, they should be thrown into special yellow plastic bags. Chinese people who have just arrived in Germany often don’t know this. This kind of plastic bag with an eye-catching recyclable logo can be obtained for free from the nearest post office and supermarket. Other recyclable packaging such as can shells, plastic boxes, etc. can be placed in this bag regardless of their material as long as they are printed with a recyclable logo.

There is a box at the door of every supermarket in Germany to collect used batteries. Glass bottles and jars are thrown into different trash bins according to color. Glass trash bins usually come in groups of three, and the bins are marked with eye-catching color signs: brown, green, transparent and colorless to remind you not to throw away the wrong ones.

We won’t do it again if it happens a second time

The vast majority of German people support Germany’s complicated garbage classification. A friend of mine is studying at the University of Dresden. He said that when he first arrived in Germany, he lived in a student apartment. Since he didn’t have this habit in China, he mixed the garbage together and threw it out. One day, he saw the dormitory administrator wearing gloves opening his discarded garbage bags and resorting them. He was shocked and ashamed.

If you don’t follow these rules, trouble will come. Once, I was working in a garbage recycling company and followed my colleagues to a community. A German colleague opened a yellow plastic bag that said it was recyclable and found a large ball of moldy flour inside. Because the flour was too heavy, it burst the plastic bag. It was sprinkled all over the ground. According to regulations, flour should be packed in blue bags. Soon, the staff posted a warning sheet at the door of the community with the following meaning: Someone in your community littered and made a mistake. Now the first warning is issued. If it happens a second time, we will not come back.

I heard from the Germans that once the garbage recycling company occurs for the second time, the garbage collection company will "***" punish the entire community, and the community management staff will have to spend a lot of energy to coordinate, so everyone is extra careful.

The salary of German cleaning workers is generally 12 euros per hour, which is about 3,000 euros a month, which is no lower than that of office white-collar workers. (Source/"Metropolitan Express")
