Biodegradable and bio-based PHA fibers are gaining increasing attention for their potential across various sectors, including textiles. However, challenges related to stability during and after processing remain a key hurdle. To unlock their full potential, innovative strategies are being developed to enhance processing performance and material reliability.
Gas fermentation is gaining momentum. More and more bioprocesses rely on this technology, and PHA production makes no exemption. Indeed, several PHA producer start-ups and firms are testing the conversion of gases into polymers. However, C1 biological fixation faces a paradox: while gases like CO2 and CH4 are extremely abundant and polluting, thereby representing ideal feedstocks, their mass transportation within bioreactors and biomass is highly challenging.
