可生物降解的聚合物，如聚羟基链烷酸酯（PHA），可以减少全球聚合物需求增加造成的污染。尽管PHA的工业生产在过去几年中迅速增长，但其总市场份额仍然微不足道。虽然这通常归因于价格较高，主要是生产成本高造成的，但优先考虑的产品在工业上的成功也取决于政策框架。诸如生命周期分析和产品环境足迹等环境评估工具表明，优先考虑措施有助于实现温室气体减排目标、减少废物以及生物技术部门的绿色就业和创新。由于许多国家希望在生物经济概念的保护下实现这些目标，因此将其纳入各自的政策可以刺激工业PHA生产。由于PHA的工业生产在原料、能源、聚合物性质等方面的高度可变性，优化标准的选择影响新生产工艺的设计。因此，考虑生物经济产品的政治目标有助于指导可持续PHA生产的技术设计，例如在综合木质纤维素生物精炼厂中。(C)2016化学工程师学会。Elsevier B.V.出版，保留所有权利。
Biodegradable polymers such as polyhydroxyalkanoates (PHAs) can reduce pollution caused by the increasing global polymer demand. Although industrial production of PHAs grew rapidly in the past years, their total market share is still marginal. While this is often attributed to their higher price, which is mainly caused by high production costs, the industrial success of PHAs can also depend on policy framework. Environmental assessment tools such as life cycle analysis and the product environmental footprint showed that PHAs can contribute to greenhouse gas emission reduction targets, waste reduction as well as green jobs and innovation in the biotechnology sector. As many countries aspire to these targets under the umbrella of bioeconomy concepts, inclusion into the respective policies can stimulate industrial PHA production. With a high variability in the industrial production of PHAs in terms of feedstock, energy source, polymer properties etc., the choice of optimization criteria influences the design of new production processes. Considering the political targets for bioeconomy products is therefore useful to direct the technical design of sustainable PHA production, for example in integrated lignocellulose biorefineries.
