Investigation of the influence of polystyrene microplastics in wastewater on anode biofilm viability and electron transfer in microbial fuel cells performance
Researchers found that polystyrene microplastics in wastewater reduce the electricity-generating ability of microbial fuel cells — devices that use bacteria to turn waste into power — by disrupting the bacterial biofilms that transfer electrons to electrodes. Carbon-based electrodes were more resistant to microplastic interference than metal ones, suggesting material choice matters when designing systems treating microplastic-contaminated water.
