Biorefinery-based production of biodegradable bioplastics: advances and challenges in circular bioeconomy

Abstract Biodegradable bioplastics have emerged as promising alternatives to conventional plastics in the current scenario of growing demand for sustainable materials. However, the high costs associated with their production still interfere with the proper dissemination of these materials. The present review will deal with the different aspects of the production of biodegradable bioplastics in biorefineries as an approach for cost reduction and low waste generation, aligning with circular bioeconomy principles. By employing different types of biomass and conversion processes, bioplastics and their composites can be considered a valuable product in biorefineries, demonstrated by actual case studies and functional industries.
