治理塑料废弃物新技术途径探讨——专论可降解塑料的研究开发

Discussion on New Technology of Plastics Garbage Disposal ——Research and Development on Degradable Plastics

综述了可降解塑料的研究开发现状及其进展。可降解塑料的降解时控性研究，合成、加工工艺改进以及降低成本的研究，可控光－生物降解的全面降解性研究和一次性使用塑料（包括地膜、包装材料和餐具等）实用性研究，仍是今后需深入探讨的重要研究课题。文中强调，该项技术开发的首要前提是制订降解塑料及其降解性的术语定义并建立其降解性的评价试验方法。

The state of the arts in degradable plastics is reviewed.The research and development on degradable plastics should be focused on degradation time control,biodegradable plastics synthesis,improving processing technology, lowering production costs,controllable photo biodegradable plastics,application in disposal plastics (e.g. mulches,packing materials and dinner sets). It is of first importance to define the terminology of degradable plastics and establish evaluation method on degradation.
