废弃塑料的化学回收资源化利用研究进展

塑料对人类社会进步和经济发展发挥着重要作用的同时,塑料的大规模生产和使用不可避免地产生大量的废旧塑料,无疑对地表水、土壤和海洋等带来严重的污染.塑料污染已成为全球可持续发展的挑战.传统物理回收法难以满足环保和资源化的要求,发展高效化学回收资源利用势在必行.文章针对8种典型量大面广的塑料如对苯二甲酸乙二醇酯(PET)、聚...

Progress in Chemical Recovery and Resource Utilization of Waste Plastics

Plastics play an important role in human social progress and economic development. However， the large-scale production and use of plastics will inevitably produce a large amount of waste plastics， which have undoubtedly brought serious pollution to surface water， soil and ocean. Plastic pollution has become a global sustainable development challenge. The traditional physical recovery methods are difficult to meet the requirements of environmental protection and recycling. It is of great importance and urgency to develop efficient chemical recovery and resource utilization. Aiming at 8 types of typical plastics with a large quantity and a wide range of applications including polyethylene terephthalate， polyolefin （including polyethylene and polypropylene）， polyvinyl chloride and polyurethane， this paper summarized the research progress in the chemical recovery and resource utilization of waste plastics at home and abroad， especially the new technologies developed in recent 10 years. This paper can provide a good reference for the development of chemical recycling technologies of waste plastics.
