Under standard test conditions, PHB and PBHV were biodegraded anaerobically (83.9±1.3% and 81.2±1.7%, respectively) in 77 days or aerobically (83.0±1.6% and 87.4±7.5%) in 117 days, while PCL was only biodegraded (77.6±2.4%) aerobically in 177 days. Apparent biomass growth accounted for up to 30.5% of the total initial carbon depending on the bioplastic and environment. Maximum aerobic and anaerobic biodegradation rates were improved up to 331 and 405%, respectively, at the lowest particle size tested (100–250 µm). This study highlights the usefulness of a more detailed analysis of biodegradation kinetics and carbon fate to improve both the development and testing of biodegradable materials/products in the context of a circular bioeconomy.
