PHAs are being developed as biodegradable alternatives to petroleum-based plastics to reduce microplastic pollution.
A New Wave of Industrialization of PHA Biopolyesters
This review covers the growing commercial development of polyhydroxyalkanoates (PHAs), a class of biodegradable bioplastics made by microorganisms that can replace conventional fossil-fuel plastics. Unlike traditional plastics, PHAs break down naturally in soil, freshwater, and ocean environments, which would reduce microplastic pollution. With over 25 companies now producing PHAs and 30 or more brand owners adopting them, this emerging industry could help address the microplastic crisis at its source.
