中文摘要：

综述了废旧热塑性塑料作为再生材料（如涂料、建筑材料、絮凝剂和高吸水性树脂等）、化学品（如单体、低分子聚合物、化学改性聚合物和化学燃料油等）的循环利用和能源的回收利用之3种方法。最后对废旧塑料回收利用的前景进行了展望。

英文摘要：

The waste thermoplastic was reviewed by three methods,which were used for cyclic utilization ofregrown materials（such as coating,building material,flocculant and high absorbent resin）and chemicals（such asmonomers,low molecular polymer,chemical modified polymer and chemical fuel oil）,and recycling of energy.Finally,the recycling prospect of waste plastic was expected.
