废旧塑料回收利用技术研究进展

目前,废旧塑料回收率低,且产量大,给环境带来巨大压力,同时也造成了资源严重浪费,因此,开发高效可行的废旧塑料回收工艺具有重大的研究意义。主要介绍了复合法,改性再利用法,建筑材料改良剂法,机械物理法,热裂解法等技术在废物回收方面的现状,并对今后的研究方向提出了几点建议。

Research Progress of Waste Plastics Recycling Technology

Nowadays, large amount of waste plastics are produced, and the rate of recovery is low, which has brought great pressure on the environment and led to serious waste of resources. Thus, it’s of great significant to develop feasible and effective waste plastics recycling technology. In this paper, research progress of waste plastics recycling technology were reviewed, including compounding method, modification method, modifying agent for building material, mechanical method, and thermal cracking method. Finally, some suggestions were put forward.
