ClearA Review on Biological Synthesis of the Biodegradable Polymers Polyhydroxyalkanoates and the Development of Multiple Applications
This review covers the biological production of polyhydroxyalkanoates, a family of biodegradable bioplastics that bacteria naturally produce from waste carbon sources. Researchers found that these biopolymers have properties similar to conventional plastics like polypropylene but can fully biodegrade, making them a promising alternative to petroleum-based plastics. The study emphasizes that scaling up production and establishing proper end-of-life management are critical steps for PHAs to compete with conventional plastics and help reduce microplastic pollution.
