Enhancing Biogas Production Amidst Microplastic Contamination in Wastewater Treatment Systems: A Strategic Review
AI summary Read the abstract
This review examines how microplastic pollution, including tire-derived particles, interferes with wastewater treatment processes and explores strategies to optimize biogas production in systems affected by microplastic contamination.
This review highlights the significant interaction between microplastic (MP) pollution and its impact on wastewater treatment systems, focusing on optimizing biogas production. We explore various sources of MPs, including tire-derived MPs, and their introduction into wastewater environments. This review delves into the mechanical and physicochemical challenges MPs pose in treatment processes, emphasizing the need for comprehensive mitigation strategies. The biological effects of MPs on microbial consortia essential for biogas production are analyzed, particularly how these pollutants interfere with each stage of anaerobic digestion—hydrolysis, acidogenesis, acetogenesis, and methanogenesis—and, consequently, biogas generation. We examine MPs’ quantitative and qualitative impacts on biogas output and production rates, uncovering how MPs disrupt microbial activity in these stages. This review also discusses novel mitigation strategies combining different sludge pretreatment methods with MPs. Our goal is to enhance the sustainability of wastewater management by promoting efficient biogas production and environmental protection in the presence of persistent MP contamination.

How does presence of microplastics impact biogas production?
AI summary Read the abstract
This study investigated whether microplastics in sewage sludge inhibit the anaerobic digestion process used to break down organic matter and produce biogas at wastewater treatment plants. Understanding whether plastic particles slow biogas production is important both for wastewater treatment efficiency and for assessing the risks of processing sludge that contains microplastics.
Overcoming micro/nanoplastics-induced inhibition in anaerobic digestion: Advances in remediation techniques
AI summary Read the abstract
This review examines how micro- and nanoplastics inhibit anaerobic digestion performance — reducing biogas yield and organic removal — and surveys remediation strategies including physical, chemical, and biological approaches to overcome their disruptive effects in waste treatment systems.
Analysis of technologies for biogas production through filtration and utilisation of wastewater in an urban environment
AI summary Read the abstract
Researchers tested a multi-step wastewater treatment system combining filtration, bacterial fermentation, and membrane processing. After full treatment, the water's microplastic content was reduced to 110-180 particles per liter, along with reductions in other pollutants and improved biogas production.
Innovative Quantification of Microplastics in Digestate from Ontario Biogas Plants: Implications for Environmental Monitoring and Management
AI summary Read the abstract
Researchers quantified microplastics in digestate from nine Ontario biogas facilities using a novel Most Probable Number (MPN) method, finding concentrations of 6,200 to 26,000 MP per gram of dry solids and identifying source-separated organics feedstock as a major driver of higher contamination levels.
Systematic study of microplastics on methane production in anaerobic digestion: Performance and microbial response
AI summary Read the abstract
Microplastics are increasingly found in wastewater treatment systems, and this study systematically examined how different types, concentrations, and sizes of microplastics affect the anaerobic digestion process used to break down sewage sludge and generate biogas. Polyethylene microplastics were found to inhibit methane production, with finer particles and higher concentrations causing greater disruption to the microbial communities driving digestion. The findings matter because microplastics in sewage sludge can impair the treatment process and also end up spread on agricultural land when sludge is used as fertilizer.
