Sustainable applications of polyhydroxyalkanoates in various fields: A critical review

PHA is one of the most promising candidates in bio-polymer family which is biodegradable and environmentfriendly in nature. In recent years, it has been applied as a biodegradable alternative for petroleum-based plastic across different domains. In literature, several research groups have scrutinised the biocompatibility and biodegradability of PHA in both in vivo settings as well as in in vitro conditions. Microbial yield polyhydroxyalkanoates (PHAs) are promoted at present as biodegradable plastics. On the other hand, only a limited number of products is being commercially manufactured out of PHAs (e.g., bottles). A succession of microbes (prokaryotes in addition to eukaryotes) has been identified as potential candidates that can disintegrate PHAs. These materials have been successfully employed in packaging industry, medical devices and implants, moulded goods, paper coatings, adhesives, performance additives, mulch films, non-woven fabrics, etc. The present paper reviews and focuses on the potential applications of PHA and its derivatives in different industries.

Automated summary

PHA is a biodegradable and environmentally friendly biopolymer that has gained significant attention and application in various industries. The research on its biocompatibility and biodegradability in vivo and in vitro has been extensively conducted. Microbial-synthesized PHAs have been widely used as biodegradable plastics in packaging, medical devices, and molded goods.
