Approach on Recycle of Waste Polyethylene

聚乙烯(Polyethylene)是塑料中产量极大、用途极广的热塑性塑料之一,它是由乙烯聚合而成,可用一般热塑性塑料的成型方法加工.聚乙烯可分为低密度聚乙烯(LDPE)、高密度聚乙烯(HDPE)和线型低密度聚乙烯(LLDPE)三大类.……

The article discusses the method to reclaim and reuse waste polyethylene at home and abroad nowadays respectively from three aspects,such as the utilization of direct recycle,the utilization of modified recycle and the utilization of pyrolysis recycle,and it is compared with their recycle and application .When waste polyethylene is recycled, we should emphasize on the development of degradable plastic and eco-materials in China;At the same time,the legislation of management and recycling of Solid Waste should be strengthened, which can accomplish the harmony of economy and environment .
