Insights into the impact of polyethylene microplastics on methane recovery from wastewater via bioelectrochemical anaerobic digestion
AI summary Read the abstract
Researchers found that polyethylene microplastics inhibited methane recovery in bioelectrochemical anaerobic digestion systems by disrupting microbial communities and electrochemical performance, though low concentrations had less severe effects.
Bioelectrochemical anaerobic digestion mitigates microplastic pollution and promotes methane recovery of wastewater treatment in biofilm system
AI summary Read the abstract
Researchers found that bioelectrochemical systems can simultaneously break down microplastics in wastewater and recover methane gas for energy. The systems enhanced the degradation of polyethylene and polyvinyl chloride particles while maintaining healthy biofilm communities on the electrodes. The study suggests that combining electrochemistry with biological treatment could offer a practical approach to both microplastic removal and renewable energy recovery from wastewater.
Occurrence and Fate of Microplastics in Anaerobic Digestion of Dewatered Sludge
AI summary Read the abstract
Researchers found that microplastics introduced during wastewater treatment are transferred into sewage sludge and survive the anaerobic digestion process, meaning they remain present when sludge is applied to agricultural land. This pathway represents a significant and underappreciated route for microplastic pollution to enter terrestrial ecosystems.
Navigating the Microplastic Challenge: Unraveling the Dynamics in Anaerobic Digestion and Treatment Processes of Sewage Sludge
AI summary Read the abstract
Researchers analyzed the behavior of microplastics within anaerobic digestion processes used to treat sewage sludge, examining how particles affect microbial activity, biogas yield, and digestate quality, and what treatment modifications can improve removal. Because sewage sludge is widely applied to agricultural land as fertilizer, microplastics surviving digestion become a direct vector for soil contamination and crop uptake.
Advances in electrochemical-based treatment of microplastics in wastewater: removal performance and influencing factors
AI summary Read the abstract
This review evaluates five electrochemical technologies—electrocoagulation, electrooxidation, electroreduction, bioelectrochemistry, and electrosorption—for removing microplastics from wastewater, finding each offers high efficiency with controllable operating conditions. Because conventional treatment plants miss much of the microplastic entering waterways, scalable electrochemical solutions are urgently needed to prevent these particles from reaching drinking water and marine ecosystems.
