Summary: The increasing use of plastics and their negative impact on the environment has led to the development of renewable and biodegradable materials. Polyhydroxyalkanoates (PHAs), a class of biopolymers synthesized by microorganisms, have properties similar to petrochemical plastics but can biodegrade in various environments. The emergence of the PHA industry has attracted the attention of chemical companies, start-ups, and brand owners who are now producing and utilizing PHAs in various applications. This commercialization wave of PHAs holds great potential in reducing plastic pollution and fighting climate change.
