Garbage classification

 Garbage classification (English name: Garbage classification) generally refers to a series of activities that classify and store garbage, classify and classify garbage into a series of public resources according to certain regulations or standards. The purpose of classification is to increase the resource value and economic value of garbage, and strive to make the best use of it.

Garbage belongs to the public's private goods during the classification and storage stage. After the garbage is classified and released by the public, it becomes a regional quasi-public resource of the community or community where the public is located.

Judging from the methods of domestic garbage classification in cities at home and abroad, they are generally classified according to the composition and amount of garbage, combined with the resource utilization and treatment methods of local garbage.

Carrying out garbage classification and collection can reduce the amount of garbage disposal and treatment equipment, reduce the treatment cost, and reduce the consumption of land resources. It has several social, economic, and ecological benefits.

cause

Everyone throws a lot of garbage every day. In some areas with better garbage management, most of the garbage will be harmlessly treated by sanitary landfill, incineration, compost, etc., and the garbage in more places is often simply piled up or landfilled. , Leading to the spread of odor and polluting the soil and groundwater.

The cost of harmless treatment of garbage is very high. Depending on the treatment method, the cost of processing a ton of garbage ranges from about one hundred yuan to several hundred yuan. People consume a lot of resources, mass produce, consume a lot, and produce garbage in large quantities. The consequences will be unbearable.

Judging from the methods of domestic waste classification in cities abroad, they are generally classified according to the composition and amount of waste composition, combined with the resource utilization and disposal methods of local waste. For example, Germany is generally divided into paper, glass, metal and plastic; Australia is generally divided into compostable garbage, recyclable garbage, and non-recyclable garbage; Japan is generally divided into plastic bottles, recyclable plastic, other plastics, resource garbage, and large-scale garbage , Combustible garbage, non-combustible garbage and hazardous garbage, etc.

Classification meaning

Current situation

Garbage classification is a reform of the traditional way of garbage collection and disposal, and a scientific management method for the effective disposal of garbage. Faced with the increasing situation of increasing garbage production and the deterioration of environmental conditions, how to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the living environment through garbage classification management is an urgent issue of common concern to all countries in the world.

The reason for the increase in garbage is the improvement of people's living standards and increased consumption. According to statistics, in 1979, the amount of urban garbage collected nationwide was more than 25 million tons. In 1996, the amount of urban garbage collected was 1.16 yuan/ton, which was four times that of 1979. Although the garbage after high temperature incineration will not occupy a large amount of land, but its investment is amazing. Do we have no way to deal with garbage? There are ways, this is garbage classification. Garbage classification is to put garbage into the source at the source, and to make it a resource again through the removal and recycling of the classification.

The advantages of garbage classification are as follows:

Reduce land erosion

Some substances in domestic garbage are not easily degraded, which seriously erodes the land. Garbage classification, remove recyclable and non-degradable substances, reduce the amount of garbage by more than 60%.

Reduce pollution

Most of the waste disposal in China adopts sanitary landfill or even simple landfill, which occupies tens of thousands of acres of land; and the flies fly, the sewage overflows, and the smelly air smokes, seriously polluting the environment.
