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, abundance, characteristics, remediation approaches and future perspective
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: Sources, detection, occurrence, and removal
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
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 as emergent contaminants in landfill leachate: Source, potential impact and remediation technologies
This review examines how landfills generate microplastics as buried plastic waste gradually degrades from physical, chemical, and biological processes. These microplastics enter the environment through leachate, the contaminated liquid that seeps from landfills into surrounding soil and groundwater. The authors evaluate current remediation technologies and highlight the need for better landfill management to reduce this growing source of microplastic pollution.
Leachate from municipal solid waste landfills: A neglected source of microplastics in the environment
This review identified municipal solid waste landfills as a significant but neglected source of microplastics in the environment, explaining how physical compression, chemical oxidation, and biological decomposition of buried plastics generate microplastics that migrate via leachate into surrounding soils and water.

This review characterized microplastics in landfill leachate, covering their physical and chemical properties and the common analytical methods used for identification. Around 40% of global plastic waste ends up in landfills, making leachate a significant but understudied pathway for microplastic release into groundwater and surrounding environments.
A review on microplastics in landfill leachate: formation, occurrence, detection, and removal techniques
This review examined microplastics in landfill leachate, covering their formation from degrading plastic waste, reported concentrations in leachate, detection methods, and available removal technologies. The authors identify landfill leachate as a significant and underregulated source of microplastic release into surrounding environments.
Microplastics in Landfill Leachates in Three Nordic Countries
Researchers found microplastics in leachates from 11 landfills across Finland, Iceland, and Norway, with particles detected in all samples and fiber morphotypes dominating, indicating that landfills are a significant but underquantified pathway for microplastic release to the environment.
Microplastics in landfill leachate and its treatment
This review examines microplastic contamination in landfill leachate, documenting that polyethylene and polypropylene are the most frequently detected polymers in sizes ranging from 20 to 5,000 micrometers, with fibers, foams, films, beads, and fragments all present. The authors detail migration pathways through which leachate microplastics reach surrounding soils, groundwater, and open water bodies, and assess the effectiveness of current leachate treatment technologies for microplastic removal.

Characterisation and Migration of Microplastics (MPs.) from Leachate
This study examines how leachate from municipal solid waste landfills serves as a transport medium for microplastics and nanoplastics into groundwater and surface water. The authors recommend investing in renewable energy recovery from solid and liquid waste streams to reduce the spread of plastic pollution from landfill sites.

Legacy landfill-derived microplastics in India: terrestrial matrix pathways, spatio-temporal dynamics, and environmental risks
This review examined microplastic contamination originating from legacy landfills across India, analyzing their distribution in leachate, soils, sediments, compost, and air. Researchers found that microplastic migration is influenced by seasonal rainfall, atmospheric deposition, and landfill leachate, with polyethylene, polypropylene, and PET being the most common polymer types. The study highlights that despite India's policy advances on plastic waste management, standardized monitoring protocols and long-term field data are still needed.
How plastic waste management affects the accumulation of microplastics in waters: a review for transport mechanisms and routes of microplastics in aquatic environments and a timeline for their fate and occurrence (past, present, and future)
