ClearMunicipal 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.
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.
Katı Atık Depolama Sahası Sızıntı Sularında Mikroplastik Kirliliği
This paper examines microplastic contamination in leachate from solid waste landfill sites, reviewing evidence that landfills are an underappreciated source of microplastics reaching soils, groundwater, and surface water. As plastics in landfills degrade and fragment over time, leachate carries microplastic particles into surrounding environments. The review highlights the need for more studies to quantify and regulate this pathway of microplastic release.

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.

This review investigated microplastic contamination across soil layers at urban municipal solid waste landfill sites, finding that landfill age and waste composition influence MP type and distribution. It identified landfill soils as understudied long-term MP reservoirs with potential for leaching into surrounding environments.
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.

The study highlights that these microplastics also carry other hazardous pollutants like heavy metals and persistent organic chemicals, amplifying their environmental threat.
Solid waste: An overlooked source of microplastics to the environment
This review highlights solid waste, including landfill material, sewage sludge, and food waste, as overlooked but significant sources of microplastic pollution. Microplastics in these waste streams can carry other harmful pollutants and enter the food chain when sewage sludge is spread on farmland or leachate seeps into water sources. Understanding these pathways is critical because they represent some of the main ways microplastics move from land into the water and food that people consume.
