Polyhydroxyalkanoates (PHA) are the more attractive sustainable green plastic, and it has the potential to replace petroleum-based plastics (PBP) in the global market. Recently, most of the developed and developing countries have banned the use of traditional PBP. This increases the demand for green plastic production and positively impacts the global market. Producing green plastic from various waste streams such as whey, animal, and crude glycerol will be eco-friendly and cost-effective. However, the factors influencing the environmental sustainability of PHA production from different waste streams are still unclear. This review could be reinforced concrete to researchers to gather deep knowledge on techno-economic analysis, life-cycle assessment, environmental and ecological risks caused during PHA production from different waste streams.
聚羟基脂肪酸酯（PHA）是更具吸引力的可持续绿色塑料，它有可能在全球市场上取代石油基塑料（PBP）。最近，大多数发达国家和发展中国家已经禁止使用传统的 PBP。这增加了对绿色塑料生产的需求，并对全球市场产生积极影响。利用乳清、动物和粗甘油等各种废物流来生产绿色塑料将是环保和具有成本效益的。然而，不同废物流生产 PHA 的环境可持续性的影响因素尚不清楚。这篇综述可以为研究人员提供强化的知识，以深入了解不同废物流生产 PHA 的技术经济分析、生命周期评估、环境和生态风险。
