降解塑料目前存在的主要问题及今后发展方向

The Main Problem and the Future Development Direction of Degradation Plastics

综述了光降解塑料、生物降解塑料、光—生物降解塑料的生产方法;提出降解塑料目前存在的降解速度可控性差、降而不解、生产成本高等问题;并对市场状况及今后发展方向进行了分析。

The producing method of bio-degradation plastic, light-degradation plastic and light-bio-degradation plastic is generalized in the article. The problems of degradation plastic existing now are controllability indegradation speed, degradation but not decomposing and more production cost. The market situation and the developing direction in the future are also analyzed.
