生物可降解聚合物被设计为在处置时通过活生物体的作用降解。从淀粉、纤维素和乳酸等聚合物开发实用工艺和产品方面取得了非凡的进展。为诸如洗涤剂和化妆品的下水道产品创造可替代的可生物降解的水溶性聚合物的需求已经变得越来越重要。然而，迄今为止，消费者对生物降解性能的附加值很少或没有附加值，迫使工业界在成本效益的基础上与现有的熟悉产品进行直接竞争。此外，目前还没有处理生物可降解材料的适当基础设施。
Biodegradable polymers are designed to degrade upon disposal by the action of living organisms. Extraordinary progress has been made in the development of practical processes and products from polymers such as starch, cellulose, and lactic acid. The need to create alternative biodegradable water-soluble polymers for down-the-drain products such as detergents and cosmetics has taken on increasing importance. Consumers have, however, thus far attached little or no added value to the property of biodegradability, forcing industry to compete head-to-head on a cost-performance basis with existing familiar products. In addition, no suitable infrastructure for the disposal of biodegradable materials exists as yet.
