The impact of waste plastics on the ecological environment

With the rapid development of society and economy, the output of human urban domestic waste is increasing year by year, and the proportion of waste plastics is also increasing year by year. At present, the proportion of recyclables in urban domestic waste in China has exceeded 30%, mainly plastic, paper, rubber, metal and glass, among which waste plastics account for a considerable proportion.

　　The impact of waste plastics on the ecological environment cannot be ignored. For example, because of its non-degradability, it can cause "white pollution" problems. Domestic garbage and waste plastics from landfills are mostly sorted through a complete set of sorting equipment. The sorted waste plastics find a way out according to local market demand or government requirements.

The sorting method mainly uses the physical and chemical properties of waste plastics, and separates waste plastics from domestic waste or waste through corresponding sorting equipment. In terms of resource utilization, waste plastics can be directly regenerated, modified, regenerated, incinerated, catalytic cracking, hydrocracking, etc.
