Degradation of polyethylene and polypropylene microplastics by advanced oxidation processes
AI summary
This study explored the role of biofilm formation on microplastic surfaces in aquatic environments, finding that microbial colonization altered particle buoyancy and promoted vertical transport toward the sediment. The plastisphere community composition differed markedly from surrounding water, potentially influencing contaminant cycling.

Removal of Environmental Microplastics by Advanced Oxidation Processes
AI summary Read the abstract
This review examined the use of advanced oxidation processes (AOPs) to degrade and remove microplastics from surface waters, ocean waters, soils, drinking water, and wastewater. AOPs represent a promising technological pathway for eliminating microplastics at treatment facilities, which is critical given that conventional systems fail to fully prevent microplastic entry into drinking water and food sources.
Environmental microplastics and their additives—a critical review on advanced oxidative techniques for their removal
AI summary Read the abstract
Researchers reviewed how advanced oxidation processes — including photocatalysis and electro-Fenton methods — can break down common microplastics and their chemical additives like BPA in water, finding these techniques are more effective than traditional treatment methods but still require further study for large-scale use.
Case Studies on the Polymer-Water Nexus: Microplastic Degradation Using Catalyzed Wet Oxidation
AI summary Read the abstract
Case studies of catalyzed wet oxidation — a process using high temperature, pressure, and chemical catalysts — demonstrated effective degradation of microplastic polymers in water, converting them to smaller organic molecules or CO2. This technology offers a route to complete microplastic elimination from wastewater streams rather than filtration and disposal, which is critical as conventional treatment plants fail to remove a significant fraction of plastic particles.
Microbial Biodegradation of Plastics and Microplastics: Recent Development
AI summary Read the abstract
Researchers reviewed recent advances in microbial biodegradation of plastics and microplastics, identifying key bacterial and fungal species capable of breaking down synthetic polymers and highlighting the biological mechanisms that could underpin scalable plastic waste remediation strategies.
