The search for new materials that replace fossil fuel-based plastics has been focused on biopolymers with similar physicochemical properties to fossil fuel-based plastics, such as Polyhydroxyalkanoates (PHA). The present paper reviews the challenges of scaling-up PHA production from waste streams during the period from 2014 to 2016, focusing on the feasibility of the alternatives and the most promising alternatives to its scaling-up. The reviewed research studies mainly focus on reducing costs or obtaining more valuable polymers. In the future, the integration of PHA production into processes such as wastewater treatment plants, hydrogen production or biodiesel factories could enhance its implementation at industrial scale.
寻找替代基于化石燃料的塑料的新材料的重点一直集中在具有与基于化石燃料的塑料相似的物理化学性质的生物聚合物上，如聚羟基烷酸酯（PHA）。本文综述了 2014 年至 2016 年期间从废物流中扩大 PHA 生产规模所面临的挑战，重点介绍了替代方案的可行性和最有前途的扩大规模替代方案。综述的研究主要集中在降低成本或获得更有价值的聚合物上。未来，将 PHA 生产整合到废水处理厂、氢气生产或生物柴油工厂等过程中，可以提高其在工业规模上的实施。
