Addressing Microplastic Pollution: What Can Bioelectrochemical Systems Offer?
AI summary Read the abstract
This paper reviews how bioelectrochemical systems, which combine microbes and electrical processes, might help break down microplastic pollution in water, since regular wastewater treatment plants cannot remove it well. The authors discuss current limitations in this technology and outline research priorities for future development.
Abstract Plastic waste, particularly from microplastics (MPs), has become a pervasive pollutant in aquatic environments, while conventional wastewater treatment plants remain largely ineffective at removing these persistent contaminants. Bioelectrochemical systems (BESs) have emerged as promising platforms for sustainable environmental mitigation, integrating microbial metabolism with electrochemical processes for the concomitant removal of contaminants and resource recovery. Despite decades of research, the application of BES in MP remediation remains at an embryonic stage, facing significant challenges related to degradation efficiency, mechanistic understanding, reactor design, and process scalability. This Perspective argues that BESs, particularly when integrated with bioelectro-Fenton processes and microbial electrosynthesis, can offer a transformative pathway for coupling MP degradation with the production of value-added chemicals. Existing scientific and engineering lacunae that limit the practical implementation of BES are uncovered, and a conceptual blueprint is envisioned to guide the development of next-generation BES technologies for sustainable MP remediation and circular resource recovery. By highlighting key research priorities and future opportunities, this Perspective aims to stimulate interdisciplinary efforts to consolidate the potential of BES-based MP mitigation as a viable remediation strategy.

The exploitation of bio-electrochemical system and microplastics removal: Possibilities and perspectives
AI summary Read the abstract
This review explores bio-electrochemical systems as a sustainable alternative for removing microplastics from water, since current removal methods are costly, energy-intensive, and can release toxic chemicals. Bio-electrochemical systems use microorganisms to generate electricity while simultaneously treating wastewater, offering a cleaner approach. Though still in early research stages, this technology could provide an efficient and environmentally friendly way to reduce microplastic contamination in water supplies.
Review and future outlook for the removal of microplastics by physical, biological and chemical methods in water bodies and wastewaters
AI summary Read the abstract
This review compares physical, biological, and chemical methods for removing microplastics from water and wastewater, including newer approaches like advanced membranes, bacterial degradation, and electrochemical treatment. Each method has trade-offs between removal efficiency, cost, and environmental impact, and no single technique currently solves the problem completely. The review emphasizes that developing effective microplastic removal technology is urgent for protecting both ecosystems and human drinking water supplies.
Microplastics in aquatic systems: An in-depth review of current and potential water treatment processes
AI summary Read the abstract
This review provides a detailed examination of microplastic contamination in aquatic systems and evaluates current and emerging water treatment technologies for their removal. Researchers assessed methods ranging from conventional coagulation and filtration to advanced techniques like membrane bioreactors and electrochemical processes. The study concludes that while no single technology fully eliminates microplastics, combining multiple treatment approaches offers the most promising path forward.
Combating microplastic pollution in water: the role and limits of electrochemical methods
AI summary Read the abstract
Microplastics, tiny plastic bits that show up in our water and even our bodies, are notoriously hard to remove, and this review looked at whether electricity-based treatments could break them down. The findings show that current methods mostly just modify the surface of microplastics rather than fully destroying them, and energy costs vary wildly between studies, meaning this technology isn't yet ready to reliably clean up our water supply. The takeaway: while promising, electrochemical treatment needs more standardized testing and likely combination with other methods before it can be trusted as a real-world solution to microplastic contamination.
A comprehensive review of microplastics in wastewater treatment plants
AI summary Read the abstract
This review surveys microplastic removal technologies used in wastewater treatment plants, comparing membrane bioreactors, electrocoagulation, coagulation-sedimentation, and biodegradation approaches. Understanding removal efficiency at treatment plants is critical because they are a primary pathway by which microplastics — and the toxic chemicals they carry — reach rivers, coastal waters, and ultimately drinking water supplies.
