Biodegradation of Bioplastics in Anaerobic Aqueous Conditions

Gregg Khan

Under aerobic and anaerobic aqueous circumstances, the biodegradation of PHB, PHBV, PBS, PBAT, PCL, PLA, and a PLA-PCL blend was studied to determine the rate, extent, carbon fate, and particle size effect [1]. PHB and PBHV decomposed either anaerobically (in 77 days) or aerobically (in 117 days, respectively, at 83.0 1.6% and 87.4 7.5%. While PCL only underwent aerobic biodegradation (77.6 2.4%) after 177 days [2]. Depending on the bioplastic and its state, apparent biomass increase accounted for 10.5% to 30.5% of the total starting carbon [3]. At the low particle size examined, the maximum aerobic and anaerobic biodegradation rates were increased by 331 and 405%, respectively [4].
