The United Nations defined 17 Sustainable Development Goals (SDGs) in 2016 and agreed on fighting to confront the climate change and protecting the oceans and forests. Subsequently, the sustainable production of bioplastics is gradually gaining reputation and significance. With the usage of bioplastics such as biodegradable polyhydroxyalkanoates (PHAs) various SDGs would be tackled, but costs remain a crucial factor for competing against fossil-based plastics. Appropriate local feedstock selection can help to reduce the production costs and minimize transportation routes. In this work, four feedstock generations are introduced and respective conversion strategies to PHA are presented. Whilst the focus is on mapping the abundances of feedstocks and potential PHA production capacities in Europe, utilization of animal by-product streams is also highlighted as a rather unconventional but highly abundant feedstock for PHA production.
联合国于 2016 年定义了 17 项可持续发展目标（SDGs），并同意共同应对气候变化，保护海洋和森林。随后，生物塑料的可持续生产逐渐获得认可和重视。通过使用可生物降解的聚羟基烷酸酯（PHA）等生物塑料，可以解决多个可持续发展目标，但成本仍是对抗化石基塑料的关键因素。适当选择当地的原料可以帮助降低生产成本并减少运输路线。在这项工作中，引入了四代原料，并提出了各自转化为 PHA 的策略。虽然重点是绘制欧洲原料的丰度和潜在 PHA 生产能力图，但也强调了动物副产品流作为 PHA 生产的一种相当非常规但非常丰富的原料的利用。
