The need for a sustainable and circular bioeconomy model is imperative due to petroleum non-renewability, scarcity and environmental impacts. Biorefineries systems explore biomass to its maximum, being an important pillar for the development of circular bioeconomy. Polyhydroxyalkanoates (PHAs) can take advantage of biorefineries, as they can be produced using renewable feedstocks, and are potential substitutes for petrochemical plastics. The present work aims to evaluate the current status of the industrial development of PHAs production in biorefineries and PHAs contributions to the bioeconomy, along with future development points. Advancements are noticed when PHA production is coupled in wastewater treatment systems, when residues are used as substrate, and also when analytical methodologies are applied to evaluate the production process, such as the Life Cycle and Techno-Economic Analysis. For the commercial success of PHAs, it is established the need for dedicated investment and policies, in addition to proper collaboration of different society actors.
由于石油的不可再生性、稀缺性和对环境的影响，需要建立一个可持续和循环的生物经济模式。生物炼制系统最大限度地利用生物质，是发展循环生物经济的重要支柱。聚羟基烷酸酯（PHA）可以利用生物炼制，因为它们可以使用可再生原料生产，并且是石化塑料的潜在替代品。本工作旨在评估生物炼制中 PHA 生产的工业发展现状及其对生物经济的贡献，以及未来的发展要点。当 PHA 生产与废水处理系统耦合时，当使用残留物作为底物时，以及当应用分析方法来评估生产过程时，如生命周期和技术经济分析，都会注意到进展。为了 PHAs 的商业成功，需要专门的投资和政策，以及不同社会行为者的适当合作。
