Summary

Researchers explored using low-quality animal by-product waste streams — including fats, fat-protein emulsions, and high-ash materials — as low-cost feedstocks for producing PHA biopolymers, a biodegradable alternative to conventional plastics that could reduce both production costs and waste disposal burden.

In future, the PHA production cost could be lowered by using the described animal by-product streams as feedstock.

Advanced approaches to produce polyhydroxyalkanoate (PHA) biopolyesters in a sustainable and economic fashion

This review examines strategies to reduce polyhydroxyalkanoate (PHA) bioplastic production costs by replacing expensive first-generation feedstocks (glucose, starch) with carbon-rich industrial waste streams as second-generation substrates. Researchers describe results from the EU-funded ANIMPOL and WHEYPOL projects, which demonstrated PHA production from animal processing and whey waste residues, improving economic viability and sustainability.

Valorization of Agri-Food Waste into PHA and Bioplastics: From Waste Selection to Transformation

This review examines how food and farming waste can be converted into biodegradable bioplastics called PHAs, which could replace petroleum-based plastics. The process uses bacteria to transform waste materials like whey and potato peelings into plastic that naturally breaks down. Developing viable alternatives to conventional plastics is critical for reducing the flow of microplastics into the environment and human food chain.

The synthesis of polyhydroxyalkanoates from low carbon wastewater under anaerobic-microaerobic process: effects of pH and nitrogen and phosphorus limitation

Researchers optimized conditions for producing polyhydroxyalkanoates (PHAs) — biodegradable bioplastics — from wastewater using bacteria under anaerobic-microaerobic conditions. Controlling pH and nutrient levels significantly improved PHA production yield. This work advances the development of sustainable plastic alternatives made from waste materials.
