由塑料废弃物引起了[白色污染]问题，故提倡使用降解塑料。目前，国内降解塑料生产线，存在投资大、生产成本高、工艺不稳定等因素，成了降解塑料推广的主要障患。成都市柯力化工研究所，第一条年产生物、光双降解淀粉塑料一千吨，工业化生产线在一九九四年十月建成投产后，又 Due to the problem of [white pollution] caused by plastic waste, it is advocated to use degradable plastics. At present, domestic degradative plastics production lines have major investment, high production costs, and unstable processes, which have become major barriers to the promotion of degradable plastics. Chengdu Keli Chemical Research Institute, the first year of production, light double-degradable starch plastic 1,000 tons, industrial production line was completed and put into operation in October 1994,
