What are the slogans advocating garbage classification?

Garbage classification refers to the general term for a series of activities that classify, store, place and transport garbage according to certain regulations or standards, thereby transforming it into public resources. The purpose of classification is to improve the resource value and economic value of garbage, strive to make the best use of materials, reduce the amount of garbage disposal and processing equipment, reduce processing costs, reduce the consumption of land resources, and have social, economic, ecological and other benefits.

Garbage is the private property of the public during the classification and storage stage. After the garbage is classified and released by the public, it becomes a regional quasi-public resource in the community or community where the public is located. The garbage is classified and transported to garbage collection points or transfer stations. It later became a non-exclusive public resource. Judging from the methods of classifying domestic waste in various cities at home and abroad, most of them are classified according to the composition and production volume of the waste, combined with the resource utilization and treatment methods of local waste.

The advantages of waste classification are as follows:

Reducing land erosion

Some substances in domestic waste are not easy to degrade, causing serious erosion of the land. Garbage classification, removing recyclable and non-degradable materials, reducing the amount of garbage by more than 60%.

Reduce pollution

China's garbage disposal mostly uses sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; insects and flies fly around, sewage overflows, and odor The sky is full of smoke, seriously polluting the environment.

Waste plastics in the soil can lead to reduced crop yields; discarded waste plastics are accidentally eaten by animals, resulting in accidents in which animals die. So recycling can also reduce harm.

Turn waste into treasure

China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls, and billions of disposable chopsticks every year. These account for 10% of domestic waste. 8~15. One ton of waste plastic can recycle 600 kilograms of diesel. Recycling 1,500 tons of waste paper can avoid cutting down the trees used to produce 1,200 tons of paper. One ton of cans can be melted to form one ton of fine aluminum blocks, which can save 20 tons of aluminum ore. 30 to 40% of household waste can be recycled, so we should cherish this small but profitable resource. You can also use cans to make pencil boxes, which is environmentally friendly and saves resources.

Furthermore, other substances in garbage can also be converted into resources. For example, food, grass, and fabrics can be composted to produce organic fertilizers; garbage incineration can generate electricity, heating or cooling; bricks, tiles, and dust can be processed into Building materials, etc. If the resource potential contained in recycling domestic waste can be fully tapped. It can be seen that if the garbage generated in the consumption process is classified in time, recycling and reuse is the best way to solve the garbage problem.

Summary

The benefits of waste classification are obvious. After the garbage is sorted, it is sent to the factory instead of the landfill, which not only saves land, but also avoids the pollution caused by landfill or incineration, and can also turn waste into treasure. In this battle between man and garbage, people turn garbage from enemies into friends.

Therefore, garbage classification 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.
