Microplastics in Landfill Leachate: Sources, Pathways, and Mitigation Approaches
AI summary Read the abstract
This review summarizes existing research on tiny plastic particles found in liquid waste that drains from landfills. Studies found widely varying amounts of microplastics in this leachate, and it can carry the particles into rivers and other water systems. Current cleanup methods face challenges, and the review calls for more consistent testing methods and better treatment technologies.
Landfill leachate is increasingly recognized as a complex and hazardous waste stream, with microplastics (MPs) emerging as persistent contaminants of global concern. This review synthesizes current knowledge on the sources, transport pathways, and mitigation strategies of MPs in landfill leachate. From a global perspective, MP concentrations in landfill leachate span from 0.16 items/L to 33,213 items/L, highlighting the potential roles of waste composition, landfill management, and environmental conditions in shaping their distributions. Leachate acts as an important mobilization vector, facilitating the transfer of MPs from terrestrial environments to aquatic systems, with potential implications for food webs and human exposure. Existing mitigation strategies, including biological, physical, and chemical treatments, are evaluated, yet their effectiveness remains constrained by the complexity of leachate matrices. Future efforts should focus on establishing standardized analytical methods, particularly for smaller MPs and diverse polymer types, and developing advanced treatment technologies capable of efficiently removing MPs from landfill leachate systems.

AI summary Read the abstract
This review examines the sources, abundance, and characteristics of microplastics found in landfill leachate, a difficult-to-treat waste liquid that can carry pollutants into the environment. The authors highlight the urgent need for standardized microplastic analysis methods and more research into cost-effective approaches for removing microplastics from leachate before it reaches waterways.
Microplastics in Landfill Leachate

This review examines microplastic contamination in landfill leachate, the liquid that drains from landfills and can contaminate groundwater and surface water. Landfills are major reservoirs of plastic waste that generate microplastics through physical and chemical breakdown, representing a significant but often overlooked contamination pathway.
Microplastics in landfill leachate: Sources, detection, occurrence, and removal
AI summary Read the abstract
This review examines how landfills have become a significant source of microplastics entering the environment through leachate -- the liquid that seeps out of waste. Polyethylene, polystyrene, and polypropylene are the most common microplastics found in landfill leachate, and while treatment can remove up to 100% of them, many facilities are not yet equipped to filter these particles before they contaminate surrounding water sources.
Microplastics in landfill leachate: Occurrence, health concerns, and removal strategies
AI summary Read the abstract
This review examines how microplastics form and accumulate in landfill leachate, the liquid that drains from waste sites. As plastic waste breaks down in landfills, it releases microplastic particles that can contaminate surrounding soil and water. The authors assess health concerns from leachate-borne microplastics and evaluate removal strategies, highlighting an often-overlooked pathway for microplastic pollution.
Microplastics in landfill leachates: The need for reconnaissance studies and remediation technologies
AI summary Read the abstract
Researchers reviewed studies on microplastics in landfill leachate — the liquid that drains through waste — finding concentrations up to 291 particles per liter that can be reduced by treatment but never fully eliminated. The study argues that landfills are an underappreciated source of microplastic pollution and urges development of better containment and removal technologies.
