1, reducing pollution
At present, sanitary landfill or even simple landfill is mostly used in garbage disposal in China, covering tens of thousands of acres;
Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment.
Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can also reduce the harm.
2. Reduce land occupation
Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded.
The garbage sorting room removes recyclable and non-degradable substances, and the amount of garbage is reduced by more than 60%.
Step 3 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, accounting for 8- 15% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper.
Step 4 transfer
Different kinds of garbage are diverted, which greatly reduces the amount that eventually enters the sanitary landfill and prolongs the service life of the landfill.
5, help to increase employment.
Domestic waste classification is a labor-intensive industry. It is estimated that every 100 ton of domestic waste will increase employment opportunities 100-200 people, including propaganda, mobilization, cleaning, sanitation, sorting and other part-time and full-time personnel.
