在实验室堆肥条件下，研究了8种生物降解塑料的降解性能。计算了最终降解性，其定义为以CO2形式损失的碳与已添加到堆肥材料中的塑料颗粒或粒料中所含碳的摩尔比。生物降解塑料的最终降解性被发现强烈依赖于塑料的种类。在50°C堆肥的8天时间内，本文测试的八种塑料的降解率范围从很小的百分比到大约65%。
Eight kinds of biodegradable plastics were examined in controlled laboratory composting conditions for their degradability. Ultimate degradability, defined as a molar ratio of carbon loss as CO2 to the carbon contained in the plastic particles or pellets that have been added to the composting material, was calculated. The ultimate degradability of the biodegradable plastic was found to be dependent strongly on the kind of the plastic. The degradability of the eight kinds of plastics tested herein ranged from a small percentage to approximately 65% over the 8-day period of the 50°C composting.
