摘　　要：随着我国经济的快速发展,塑料在日常生活和各个工业领域的应用涉及到了各个方面,但是废塑料的数量仍在急剧增加中。每年废旧塑料的回收利用率大约只有25%,有1400万t塑料制品没有得到合理处置,经济浪费高达280亿元。同时由于塑料密度小、难降解的特性使得白色污染从20世纪90年代开始困扰人类至今,微塑料也从2004年进入了人类的视线,被纳入了研究范围。因此如何控制废塑料的回收再利用已成为当下刻不容缓的研究议题。With the rapid development of our country’s economy,the application of plastics in daily life and various industrial fields involves all aspects,but the amount of waste plastics is also increasing sharply. The annual recycling rate of waste plastics is only about 25%,14 million tons of plastic products are not properly disposed of,and the economic waste is as high as 28 billion yuan. At the same time,due to the low density and difficult-to-degrade characteristics of plastics,white pollution has plagued humans since the 1990 s. Microplastics have also entered the sight of humans in 2004 and have been included in the scope of research. Therefore,how to control the recycling of waste plastics has become an urgent research topic.
