In 1997, the world degradable plastic market was predicted to be around 20 million pounds, with a sales revenue of 23 million US dollars; It is expected to increase by 35% by 2004. The degradable plastics present in the US and Japanese markets include biodegradable polyester, such as polylactic acid, biodegradable PET, polybutylene succinate/hexanoate, polyhydroxybutyrate/valerate, polyethylene succinate, polyesteramide, and polycaprolactone/mixture; Starch and its mixture; And other plastics added with additives to enhance degradation ability. The reason for the growth is the increase in the use of environmentally friendly plastics, and another reason is the reduction of production costs. By expanding production and economic scale, manufacturers have lowered their prices. However, the high cost of biodegradable resins and the strong dominance of various existing plastics in their market make it difficult for biodegradable plastics to enter the market.
