Significance of garbage classification to social and economic development

The importance of a country's land resources is self-evident, and as we all know, the per capita land in China, especially the per capita arable land, is very weak. Turning precious land into a garbage dump is really a slow suicide.

At present, at least 40% of domestic garbage in Beijing can be recycled, which can reduce the landfill volume by 40%. With the increase of the proportion of recyclable garbage, more and more land will be saved from the threat of garbage.

Step 2 reduce pollution

Garbage sorting 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 easy to degrade), 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.

Modern landfill is also difficult to eliminate the possibility of toxic and harmful substances leakage. Many toxic chemical wastes buried underground, methane and biogas are hidden dangers. Rainwater falling into landfills returns to the ground with underground harmful substances, which has caused serious pollution in developed countries.

3. Renewable resources

There is no garbage on the earth, and garbage is a resource that human beings have not treated correctly. The ecological value of this permanently destroyed resource is incalculable. Through the classified recycling of garbage, people can completely turn garbage into resources: good paper is made of wood. At present, China loses 6 million tons of waste paper every year, which is equivalent to wasting forest resources1-50,000 mu.

Recycling a ton of waste paper can regenerate 800 kilograms of good paper and save 17 trees; 240 kilograms of soda ash is used less, which reduces the pollution discharge of papermaking by 75% and saves the energy consumption of papermaking by 40-50%.

Extended data:

017 On March 18, the General Office of the State Council released 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. It is planned that by the end of 2020, a system of laws, regulations and standards related to waste classification will be basically established, and compulsory classification of domestic waste will be implemented in the first batch of domestic waste classification demonstration cities such as municipalities directly under the central government, provincial capital cities and cities with separate plans.

Other first demonstration cities for domestic waste classification include Handan City in Hebei Province, Suzhou City in Jiangsu Province, Tongling City in Anhui Province, Yichun City in Jiangxi Province, Tai 'an City in Shandong Province, Yichang City in Hubei Province, Guangyuan City, 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.
