why is it important to classify wastes?
Answers
Answer:
Careful and robust classification of waste materials is important given the strict controls required for storage, treatment and disposal of hazardous waste, in addition to the higher costs involved compared with other waste types. It is also important to ensure that wastes are disposed of in the correct landfill sites.
1. Reduce environmental pollution garbage sorting
Because garbage is not classified, modern garbage contains chemical substances, and some will cause the incidence of people to increase. If you dispose of garbage by landfilling or stacking, even if you are away from the living place and landfill the garbage, and adopt the corresponding isolation technology, it is difficult to prevent the penetration of harmful substances, which will enter the entire ecosystem with the circulation of the earth , Pollution of water sources and land, through plants or animals, will ultimately affect people's health.
2. Save land resources
At present, there are two ways to dispose of garbage in our country, one is landfilling, and the other is garbage stacking. No matter what kind of garbage, the essence is to transport garbage from one place to another and still occupy land resources. For now, landfills are the simplest and most convenient way of disposal, but they are extremely unfavorable for future development. The land resources of a country are fixed, and the per capita land in China, especially the cultivated land per capita, is below the world average. Landfills are irrecoverable sites, that is, they cannot be used as living quarters again. If the land resources are turned into garbage disposal sites, it is equivalent to chronic suicide, and the cost of land restoration in the future will be very expensive.
3. Utilization of renewable resources
The generation of garbage is because people do not make good use of resources, and discard the resources they do not use as garbage. This waste of resources is inestimable for the loss of the entire ecosystem. Once the garbage is disposed of by landfill or incineration It is extremely difficult to reuse it. Before the garbage treatment, the garbage can be turned into treasure through waste sorting and recycling, such as recycling paper can protect the forest and reduce the waste of forest resources; recycling biological waste such as peel vegetables can be used as a green fertilizer to make the land more fertile.
