Biogas generation potential of starch-and polylactide- based biodegradable plastics

Original language description

Plastic materials decompose with an extremely slow rate and many decades are required for their complete degradation. Lately, commercial plastics have been partially replaced by biodegradable additives. Polylactic acid (PLA) and starch-based biopolymers are indicative alternatives employed to replace a 50-100 % of the mass of conventional plastic materials. In this work, a conventional and two different biodegradable commercial bags were subjected to single-stage mesophilic anaerobic digestion for 100 days to investigate their degradation performance and examine their biogas and methane production potential. LDPE-based plastic (LDPE-50) decomposed only negligibly producing 0.0785 m3 kgVS-1 of methane after 100 days of digestion whereas PLA-based bioplastic (PLAS-31) showed a better degradation performance (0.1782 m3 kgVS-1). A methane production of 0.1941 m3 kgVS-1 was attained from a second type of PLA-based biodegradable bag (PLAS-13) indicating that bioplastics under specific anaerobic digestion conditions could provide a significant amount of biogas. The degradable organic material in bioplastics was the principal factor defining their conversion to biogas and methane. Anaerobic digestion had a minimal impact on the surface of LDPE-50, while the most significant modification of surface was seen for PLAS-13 where clean polymeric structures emerged after digestion due to a removal of a significant fraction of organics. PLAS-31 showed a great potential to further degrade even after the end of the 100 days of anaerobic digestion.
