Why do we have to divide garbage into so many types

Most of the garbage disposal methods are still in the traditional way of stacking and landfilling, occupying tens of thousands of acres of land; And insects and flies fly around, sewage overflows, and the smell is stinking, seriously polluting the environment. Therefore, garbage sorting and collection can reduce the amount of garbage disposal and treatment equipment, reduce the cost of treatment, reduce the consumption of land resources, and have social, economic and ecological benefits. The advantages of garbage sorting are as follows:

1. Reduce land occupation: Some substances in domestic garbage are not easy to degrade, so that the land is seriously eroded. Garbage classification, remove the most advanced and non-degradable substances, and reduce the amount of garbage by more than 50%.

2. Reduce environmental pollution: Waste batteries contain toxic substances such as metal mercury and cadmium, which will cause serious harm to human beings; Waste plastics in the soil can lead to reduced crop yields; Waste plastic discarded is accidentally eaten by animals, resulting in accidents that lead to the death of animals from time to time. Therefore, the use of ** can reduce the harm.

3 Turning waste into treasure: China uses 4 billion plastic fast food boxes and 5-700 million instant noodle bowls every year, and waste plastic accounts for 4-7% of household waste. 1 ton of waste plastic can be used to recycle 600 kg of diesel.

**1,500 tonnes of waste paper, exempt from the felling of trees used to produce 1,200 tonnes of paper. After one ton of cans are melted, they can form one ton of very good aluminum blocks, and 20 tons of aluminum ore can be mined. 30%-40% of the production waste can be used, and this small and large profit resource should be cherished.

You can also use cans to make pencil cases, which is both environmentally friendly and resource-saving.

The significance of garbage sorting.

1. Separate the kitchen waste with perishable organic components, provide high-quality raw materials for compost, and produce high-quality organic fertilizer, which is conducive to improving soil fertility and reducing the amount of chemical fertilizer;

2. Separation of kitchen garbage with high moisture content improves the calorific value of other garbage incineration, and reduces the difficulty of secondary pollution control of domestic waste incineration;

3. Sorting out hazardous waste reduces the content of heavy metals, organic pollution sources and pathogenic bacteria in domestic waste, which is conducive to the harmless treatment of domestic waste and reduces the risk of secondary pollution of water, soil and atmosphere in domestic waste treatment;

4. Divert different types of domestic waste, so that the amount of final sanitary landfill is greatly reduced, and the service life of the landfill is prolonged;

5. Increase the proportion of waste utilization, make resources recycled, reduce the demand for raw materials, and reduce carbon dioxide emissions;

6. Popularize the knowledge of environmental protection and garbage, enhance the awareness of the whole society on the sanitation industry, reduce the difficulty of sanitation workers, and form an atmosphere of respect and care for sanitation workers.

This facilitates reuse and reduces the cost of sorting these wastes.

Because the molecules of garbage and garbage are not the same, the harm is not the same.

Some are polluted, some are not polluted, and need to be used. And it's for the sake of the environment.

The significance of garbage classification is mainly as follows:

1. Reduce environmental pollution. At present, China's garbage disposal is generally in the form of sanitary landfill or even simple landfill, which occupies a lot of land and causes serious pollution to the environment. Therefore, garbage classification can reuse useful garbage and reduce the landfill of garbage, which reduces the harm to the environment.

2. Improve the public's awareness of conservation. Garbage classification allows people to learn to save resources, use resources, and develop a good living habit to improve personal quality. If people can develop good garbage sorting habits, they will pay more attention to environmental protection issues, so that they can truly know the preciousness of resources and develop the habit of saving resources.

3. Save land resources. Some substances in domestic garbage are not easily degraded, which has seriously eroded the land. After the garbage is sorted, it can be reused partially, which will reduce the amount of garbage, which will save more land resources.

People carry out garbage classification in order to protect the environment and resources, reduce the pollution of garbage to the environment, and convert garbage into first-class resources and usable energy to achieve the purpose of sustainable development. Garbage classification can be classified into categories, such as garbage, hazardous garbage, wet garbage and dry garbage, and different types of garbage can be treated in different ways. For example, garbage can be reused, hazardous garbage needs special treatment to avoid polluting the environment, wet garbage can be disposed of by composting, etc., and dry garbage can be incinerated or coarsely landfilled.

Through garbage classification, environmental pollution and resource waste can be minimized, and the ecological environment can be protected. At the same time, garbage classification also improves the efficiency of garbage disposal and resource utilization, which helps to promote the sustainable development of cities.

1.Remove the substances that can be degraded and are not easy to degrade, and reduce the amount of garbage by more than 60%, thereby reducing the occupation of soil; 2.Separate hazardous waste to reduce pollution, such as discarded batteries containing toxic substances such as metal mercury and cadmium; 3.

Turn waste into treasure, such as plastic fast food boxes, instant noodle bowls, and disposable chopsticks, most of which can be used; 4.Waste plastics are eaten by animals, resulting in accidents that kill animals from time to time, and garbage sorting can reduce the risk of animal ingestion.

Garbage classification is a general term for a series of activities that classify and store, classify and transport garbage according to regulations, so as to transform it into public resources.

How to sort garbage?

Can be ** things. It mainly includes five categories: waste paper, plastics, glass, metals and textiles. Waste paper mainly includes newspapers, periodicals, books, various packaging paper, office paper, advertising paper, cartons, etc.

Hazardous waste. It mainly includes waste batteries, waste fluorescent tubes, waste water silver thermometers, expired medicines, etc., which require special treatment.

Other garbage. Mainly including bricks, ceramics, muck, toilet waste paper, paper towels and other difficult wastes in addition to the above-mentioned types of garbage, with appropriate treatment can effectively reduce the pollution of groundwater, surface water, soil and air.

Misunderstandings of garbage classification

Myth 1: Big stick bones are kitchen waste. In fact, the big stick bone is listed as "other garbage" because it is "difficult to corrode". Similarly, corn pits, nut shells, fruit pits, chicken bones, etc. are kitchen waste.

Myth 2: Toilet paper and toilet paper are acceptable items. Toilet paper and toilet paper dissolve in water, which is not considered a "paper", similar to pottery, cigarette boxes, etc., can not be **.

Myth 3: Peanut shells are counted as other garbage. The logo of "fruit shell melon skin" is peanut shell, which is indeed kitchen waste. The waste cooking oil used at home is currently also classified as "kitchen waste".
