The significance of garbage sorting.

1. Reduce the floor area and improve the land utilization rate.

Some of the domestic garbage contains harmful substances, which are not easy to degrade, and the land is seriously damaged. If it is classified, it can be removed, reducing the amount of landfill by more than 60%.

2. Reduce waste pollution and protect the ecological environment.

China's garbage disposal mostly adopts the method of landfill, which occupies a large amount of land area, and will cause an increase in mosquitoes, sewage turbulence, unpleasant odors and other uncomfortable phenomena. In addition, waste plastics in the soil will reduce crop yields, and if eaten by animals, they will endanger their health and even lead to death, and will pollute water resources, which is also closely related to human health. **Utilization can reduce these hazards.

3. Turn waste into treasure and make effective use of resources.

According to relevant data, the number of plastic fast food boxes used in China every year is as high as 4 billion, 1 billion pairs of disposable chopsticks, and 5-700 million instant noodle bowls, which account for about 15% of domestic waste. Then, 1 ton of waste plastic can be refined into 600 kg of diesel.

**1,500 tonnes of waste paper, which can save 1,200 tonnes of paper from being cut down in the forest. 1 ton of cans can be melted into one ton of aluminum blocks, which can reduce the mining of 20 tons of mineral resources. 30%-40% of our domestic garbage can be used and used rationally, which is a resource of small capital and big profit.
