the increase in garbage is due to the improvement of people's living standards and the increase in consumption. According to statistics, in 1979, the amount of urban garbage cleared in the country was more than 25 million tons. In 1996, the freight rate for municipal garbage was 1.16 yuan/ton, four times that of 1979. Although the garbage that has been incinerated after high temperature does not occupy a large amount of land, its investment is amazing. Can we be helpless when we treat garbage? The solution is yes, this is the garbage classification. Garbage sorting is to categorize waste at the source and re-convert it into resources through classified clean-up and recycling.

The advantages of waste sorting treatment are as follows: Some substances in the occupied domestic garbage are not easily degraded, and the land is seriously eroded. Garbage sorting, removing substances that can be recycled and not easily degraded, reducing the amount of garbage by more than 60%. Reducing pollution At present, China's garbage disposal mostly adopts sanitary landfill or even simple landfill, which occupies tens of thousands of mu of land; and the insects flies, the sewage overflows, the smell is smoky, and the environment is seriously polluted. Abandoned batteries contain toxic substances such as metallic mercury and cadmium, which can cause serious harm to humans; waste plastics in the soil can cause crops to be reduced; discarded plastics are eaten by animals, causing animal deaths to occur. Recycling can therefore reduce the hazard. China uses 4 billion plastic snack boxes every year, 750-700 million instant noodle bowls, and billions of disposable chopsticks, which account for 8-15% of domestic garbage. One ton of waste plastic can be reprocessed with 600 kg of diesel. Recycling 1,500 tons of waste paper is free from cutting down the trees used to produce 1,200 tons of paper. One ton of cans can be melted to form a good ton of aluminum, and 20 tons of aluminum can be mined. 30%~40% of domestic garbage can be recycled, and the resources of this small profit should be cherished. You can also use the cans to make pencil cases, which are both environmentally friendly and resource-saving. Moreover, other substances in the garbage can also be converted into resources, such as food, grass and fabrics can be composted to produce organic fertilizer; waste incineration can generate electricity, heat or refrigeration; bricks and ash can be processed into building materials and so on. The mixture of various solid wastes is garbage, and sorting is a resource. If we can fully exploit the potential of resources contained in recycling domestic waste, only Beijing will receive an economic benefit of 1.1 billion yuan per year. It can be seen that if the garbage generated in the consumption chain is classified in time, recycling and recycling is the best way to solve the garbage problem. The benefits of garbage sorting are obvious.

After being sorted, the garbage is sent to the factory instead of the landfill, which saves the land and avoids the pollution caused by landfill or incineration. It can also turn waste into treasure. In this battle between people and garbage, people turned garbage from enemies into friends. Therefore, garbage collection and collection can reduce the amount of garbage disposal and processing equipment, reduce processing costs, reduce the consumption of land resources, and have social, economic and ecological benefits. Recyclable mainly includes waste paper, plastic, glass, metal and cloth. Waste paper: mainly includes newspapers, periodicals, books, various wrapping papers, etc. However, it should be noted that paper towels and toilet paper are too strong to be recycled due to their water solubility. Plastic: various plastic bags, plastic foam, plastic packaging, disposable plastic lunch box cutlery, hard plastic, plastic toothbrush, plastic cup, mineral water bottle, etc. Glass: mainly includes various glass bottles, broken glass sheets, mirrors, thermoses, etc. Metals: mainly including cans, cans, etc. Fabric: mainly includes discarded clothes, tablecloths, face towels, school bags, shoes, etc. These wastes are recycled through comprehensive treatment, which can reduce pollution and save resources.
