ClearPlastic Waste Degradation in Landfill Conditions: The Problem with Microplastics, and Their Direct and Indirect Environmental Effects
This review examined the degradation of plastic waste in landfill conditions and the resulting formation and spread of microplastics. The study highlights that both active and former landfills are ongoing sources of microplastic contamination through leachate and gaseous emissions, and that biological, chemical, and physical processes in landfills break down plastic waste into smaller particles that can enter surrounding environments.
The evolution and fate of waste plastics in landfills subject to physical and biochemical processes - implications for microplastics
This review examines how plastic waste in landfills is physically and biochemically transformed over time, with a focus on the conditions that generate microplastics from buried macroplastics. The authors explore implications for microplastic leaching and environmental contamination from landfill sites.
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.
Evolution and associated environmental pollution risks of micro- and nanoplastics through landfill processes
Researchers reviewed how landfills — the world's primary destination for plastic waste — generate and release micro- and nanoplastics (tiny plastic fragments under 5mm and 1 micron) into surrounding soil, water, and air. The review highlights that landfill mining and remediation activities can actually accelerate the release of these particles, complicating pollution control.
Microplastics in landfill and leachate: Occurrence, environmental behavior and removal strategies
This review examines how microplastics form and accumulate in landfills and their leachate, which is the liquid that drains from waste sites. Researchers found that landfill leachate is an overlooked source of microplastic pollution that can carry toxic substances and antibiotic resistance genes into the surrounding environment. The study evaluates current removal strategies and calls for better treatment systems to prevent microplastic contamination from waste disposal sites.
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 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
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.
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.
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 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.
Microplastics in Landfills: A Comprehensive Review on Occurrence, Characteristics and Pathways to the Aquatic Environment
This comprehensive review examines the occurrence, characteristics, and transport pathways of microplastics in and from landfills, identifying leachate, wind dispersal, and runoff as key vectors by which landfill-derived microplastics migrate into aquatic environments.

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.
