可降解塑料指在生产过程中加入一定量的添加剂(如淀粉、改性淀粉或其它纤维素、光敏剂、生物降解剂等),稳定性降低,在自然环境中较易降解的塑料。可降解塑料的市场售价是普通塑料产品的2~3倍,若成功出售,利润水平在10%,而普通的塑料利润水平在1%~3%。尽管利润水平较高,但可降解塑料目前销售阻力较大,第一是成本较高,资金占用较大,下游企业的接受能力较差;第二是 Biodegradable plastics refers to a certain amount of additives in the production process (such as starch, modified starch or other cellulose, photosensitizers, biodegradable agents, etc.), lower stability, easier to degrade in the natural environment of plastic.
