- Abstract
Biopolymers have gained popularity as an alternative product to traditional plastics due to environmental concerns. Polyhydroxyalkanoates (PHAs), one of the most well‐known forms of biopolymers, are among the many that have been discovered so far. PHA has a wide range of applications, is biodegradable and compatible with living things, but its expensive extraction and production make it difficult to compete with traditional plastics. Solvents are the most popular extraction technique but have serious economic and environmental downsides. The "green method of extraction" has become a cutting‐edge remedy for addressing the shortcomings of downstream processing. However, developing the extraction technique for affordable and environmentally friendly biopolymer production is a difficult study topic. To make it easier to choose green recovery techniques for future study, this review combines the benefits and drawbacks of the numerous PHA recovery methods that are already in use. Also, advanced green downstream methods are scrutinized that undoubtedly makes PHA replace conventional plastics and reach a market globally promoting sustainability.
