ClearMicrobial PolyHydroxyAlkanoate (PHA) Biopolymers – Intrinsically Natural
This review covered microbially produced polyhydroxyalkanoate (PHA) biopolymers as naturally biodegradable alternatives to fossil-based plastics, arguing that PHAs offer a circular solution that avoids microplastic formation and elevated CO2 release associated with conventional plastic end-of-life scenarios.
PHA, the Greenest Plastic So Far: Advancing Microbial Synthesis, Recovery, and Sustainable Applications for Circularity
This review examines polyhydroxyalkanoates (PHAs), a family of biodegradable plastics made by bacteria that could replace conventional petroleum-based plastics. Switching to PHAs could significantly reduce microplastic pollution because unlike traditional plastics, these materials fully break down in the environment rather than fragmenting into persistent microplastic particles.
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.
A 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.
Biosynthesis of Polyhydroxyalkanoates (PHAs) by the Valorization of Biomass and Synthetic Waste
This paper explores the production of polyhydroxyalkanoates (PHAs), biodegradable microbial polymers, from biomass and waste feedstocks as a sustainable alternative to conventional synthetic plastics. PHAs can be naturally synthesized by bacteria, offering a pathway to biodegradable plastics that do not persist as microplastic pollution.

Switching from petro-plastics to microbial polyhydroxyalkanoates (PHA): the biotechnological escape route of choice out of the plastic predicament?
This review makes the case for replacing petroleum-based plastics with microbially produced biodegradable alternatives (PHAs), particularly for packaging and medical applications. If produced efficiently enough, PHAs could reduce persistent plastic waste and the resulting microplastic pollution.
Production of polyhydroxyalkanoate (PHA) biopolymer from crop residue using bacteria as an alternative to plastics: a review
This review examines how PHA, a biodegradable plastic made from crop waste using bacteria, could serve as a sustainable alternative to conventional plastics. While PHA breaks down naturally unlike traditional plastics that fragment into microplastics, challenges remain in making it heat-stable and cost-competitive enough for widespread industrial use.
Bacterial Production of Hydroxyalkanoates (PHA)
