MICROPLASTICS IN BIOGAS PRODUCTION: UNVEILING THE IMPACT OF PLA, PET, PVC AND THEIR MIXTURES ON ANAEROBIC

Popis výsledku v původním jazyce

Anaerobic digestion, a critical process for biogas production as a renewable energy source, can be affected by the infiltration of microplastics. This study evaluates the impact PLA, PET, PVC, and their combinations on biogas production in anaerobic fermentation.Experiments were conducted using BMT under termophilic conditions over a 70-day period. Results showed significant differences in biogas production across the tested materials. PLA yielded the highest cumulative methane production at 0.416 m3 CH4/kgTS, indicating its superior biodegradability. PET and PVC produced lower cumulative methane yields, with values of 0.053 m3 CH4/kgTS and 0.095 m3 CH4/kgTS, respectively, likely due to their poor biodegradability and potential inhibition of microbial activity. These findings provide valuable insights into the influence of microplastics on anaerobic digestion and highlight important implications for waste management strategies and renewable energy production. This work was financially supported by the European Union under the REFRESH - Research Excellence For Region Sustainability and Hightech Industries, CZ.10.03.01/00/22_003/0000048via the Operational Programme Just Transformation. Experimental results were accomplished by using Large Research Infrastructure ENREGAT supported by the Ministry of Education, Youth and Sports of the Czech Republic under project No. LM2023056. The poster presentation on conference Winter School in Portugal.
