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
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 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.
Microplastics in Landfill Leachate: A Comprehensive Review on Characteristics, Detection, and Their Fates during Advanced Oxidation Processes
This review synthesizes findings on microplastics in landfill leachate, identifying it as an underappreciated environmental source of microplastic contamination generated by physical, chemical, and biological breakdown of plastic waste. The authors outline characteristics, detection methods, and pathways by which leachate-borne microplastics enter the broader environment.
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 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.
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.
Exploring the abundance of microplastics in Indian landfill leachate: An analytical study
Researchers analyzed microplastics in leachate from two major landfills in India and found concentrations of 1,473 to 2,067 particles per liter, with most particles smaller than 100 micrometers. Polyethylene terephthalate, polypropylene, cellulose acetate, and PVC were the most common plastic types identified. Since landfill leachate can seep into groundwater and nearby water bodies, these findings raise concerns about microplastic contamination of drinking water sources near dump sites.
Microplastics in landfill leachates: The need for reconnaissance studies and remediation technologies
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.
Sources, distribution, and impacts of emerging contaminants – a critical review on contamination of landfill leachate

Risk assessment of microplastics contamination in soil and leachate from different ages of landfill
Researchers assessed microplastic contamination in soils and leachate collection ponds at a landfill site in Thailand, examining how the physical and chemical characteristics of microplastics — including abundance, morphology, size, and polymer type — evolve across landfill sections of different ages. The study found that microplastic properties change significantly with landfill age, highlighting landfills as important sources of environmental microplastic pollution with implications for leachate treatment.

Municipal solid waste (MSW) landfill: A source of microplastics? -Evidence of microplastics in landfill leachate
Leachate from four active and two closed municipal solid waste landfills was analyzed for microplastics, finding 0.42–24.58 items/L across all 12 samples with 17 polymer types identified and polyethylene and polypropylene as dominant types. The study provides direct evidence that landfills release microplastics to the environment through leachate and identifies them as a significant but understudied pollution source.
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.
Critical review on microplastics in landfill leachate
Landfills are not just sites where plastic is buried — they are active sources of microplastic pollution, releasing particles into the environment through leachate, the liquid that seeps through waste. This review of global research found that polyethylene was the most common plastic type in landfill leachate, with fibers the dominant shape, and that particles as small as 0.03 mm were being detected. A particularly important unresolved question is whether the thick plastic liner membranes used to contain leachate may themselves be contributing microplastics to the very liquid they are meant to contain.
