摘　　要：随着社会与经济的快速发展,通用塑料被人们广泛使用,同时也带来了塑料污染的隐患。不加外力的情况下,废弃塑料在自然环境中难以降解且耗费时间长。废弃塑料主要通过土壤、空气以及水资源途径污染环境,目前处理这些废弃塑料的传统方法通常为回收废弃塑料加工成型成材料性能相近的产品,近年来采取特殊手段将其循环使用逐步成为一种重要的处理途径。本综述主要介绍了三大塑料PET、PP以及PU通过加工处理使其能够更加高效快捷地循环使用,通过对现有的物理法、化学法以及生物法处理这些废弃塑料将其转化为具有更高经济价值的产品,并对今后在这一领域的发展进行了展望。With the rapid development of economy and society,Recently,general-purpose plastics are widely used by people,and the passage is also a hidden danger of plastic pollution.Without external force,waste plastics are difficult to degrade in the natural environment and take a long time.Waste plastics mainly pollute the environment through soil,air and water resources.At present,the traditional method of dealing with these waste plastics is usually to recycle waste plastics and process them into products with similar material properties.Therefore,it is an important way to recycle it by special means.The three major plastics PET,PP and PU through processing to make them efficiently recycled were introduced,by treating these waste plastics by existing physical,chemical and biological methods,they can be transformed into higher-value products.It also looked forward to the future development in this field.
