Anaerobic biodegradation of biopolymers for sustainable valorization of bioplastics: Integrated kinetic modeling and microbial community assessment

: 0.9854, 0.9839, 0.9931, and 0.9772 for PLA pellet, PBS, PLA film, and bioplastic, respectively), indicating excellent model fitting accuracy. Moreover, a generalized anaerobic biodegradation model equation was developed for biopolymers. The findings demonstrated the potential applicability of anaerobic digestion for biopolymer waste valorization through simultaneous biodegradation and biogas generation, supporting sustainable waste management and circular bio-economy approaches.
