Garbage classification: What is the significance for social and economic development?

1. Saving land

The importance of a country's land resources is self-evident, and it is well known that the per capita land in China, especially the per capita arable land, is very weak. Turning precious land into a garbage dump is really an act like chronic suicide.

At present, at least 4% of the domestic garbage in Beijing can be recycled, which can reduce 4% of the landfill. With the increasing proportion of recyclable garbage, more and more land will be saved from the threat of garbage.

2. Reduce pollution

Garbage classification can avoid environmental pollution caused by landfill or incineration. There are a lot of chemical wastes in the garbage components of modern life, such as: plastics (containing chlorine and not easily degraded), batteries (containing mercury, cadmium or sulfuric acid), paint nutrients (containing organic solvents and heavy metals), cleaning chemicals and cosmetics (containing organic solvents, corrosive chemicals and carcinogens) and so on.

it is also difficult to eliminate the possibility of toxic and harmful substances leaking in modern landfills. Many toxic chemical wastes buried in the ground, methane and biogas are hidden dangers. Rainwater falling into landfills returns to the ground with underground harmful substances, causing serious pollution incidents in developed countries.

3, renewable resources

There is no garbage on the earth, and garbage is a resource that human beings have not handled correctly. The ecological value of this permanently destroyed resource is incalculable. Through the classified recycling of garbage, people can completely turn them into resources: good paper is made of wood, and at present, China loses 6 million tons of waste paper every year, which is equivalent to wasting 1-5 million mu of forest resources.

recycling one ton of waste paper can regenerate 8 kilograms of good paper and save 17 big trees; 24 kilograms of soda ash is used less, which reduces the pollution discharge of papermaking by 75% and saves the energy consumption of papermaking by 4-5%.

Extended information:

On March 18th, p>17, the General Office of the State Council issued the Implementation Plan of Domestic Waste Classification System formulated by the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development, and it is planned to basically establish the relevant laws, regulations and standards system of waste classification by the end of 22, and implement compulsory domestic waste classification in municipalities directly under the central government, provincial capitals, cities with separate plans and other first batch of domestic waste classification demonstration cities.

other first demonstration cities of domestic waste classification include Handan city in Hebei province, Suzhou city in Jiangsu province, Tongling city in Anhui province, Yichun city in Jiangxi province, Taian city in Shandong province, Yichang city in Hubei province, Guangyuan city in Sichuan province, Deyang city, Shigatse city in Xizang Autonomous Region and Xianyang city in Shaanxi province.

The scheme requires that harmful waste must be regarded as one of the compulsory classification categories, and other compulsory classification categories such as perishable garbage and recyclables can be selected.
