A Survey of Microplastic Pollution from Wastewater Treatment Plant Effluent Within the Lake Champlain Basin
A survey of wastewater treatment plant effluent found that microplastics — primarily fibers from synthetic clothing — pass through treatment processes and are discharged to waterways. The study highlights treated wastewater as a major pathway for microfiber microplastics to enter rivers and coastal waters.
Textile microfibers reaching aquatic environments: A new estimation approach
Researchers developed a new estimation approach for quantifying the mass flow of textile microfibers from household laundry that ultimately reaches aquatic environments, addressing the absence of accurate models for assessing microfiber contributions to microplastic pollution. The method provides a more systematic framework for estimating the environmental load from domestic washing.
Microfibres Release from Textile Industry Wastewater Effluents Are Underestimated: Mitigation Actions That Need to Be Prioritised
This review highlights that the release of tiny fibers from textile manufacturing wastewater is likely far greater than current estimates suggest, making it a major underrecognized source of microplastic pollution. Researchers found that existing wastewater treatment processes capture many fibers but still release significant quantities into the environment. The study calls for prioritizing better filtration technologies and upstream interventions in the textile industry to reduce fiber shedding.
Quantifying shedding of synthetic fibers from textiles; a source of microplastics released into the environment
Researchers quantified the shedding of synthetic fibers from textiles during simulated washing, finding that fabric type, age, and wash conditions significantly affected fiber release, and establishing a quantitative basis for estimating textile-derived microplastic inputs.
Microplastic pollution in aquatic environments from washing synthetic textiles
Washing synthetic textiles releases microplastic fibers into wastewater, and this study reviewed the scale of the problem and explored strategies to reduce emissions at the washing machine, garment design, and wastewater treatment levels. Textile laundering is considered one of the largest sources of microplastic fiber pollution reaching aquatic environments.
Microfibers from synthetic textiles as a major source of microplastics in the environment: A review
This review examines how synthetic textile garments release thousands of microplastic fibers during each wash cycle, making laundry a major source of microplastic pollution. Even though wastewater treatment plants capture most fibers, billions still escape into waterways each day because the incoming volume is so enormous. These fibers end up in rivers, oceans, and soil, where they can be consumed by aquatic life and eventually reach humans through the food chain.
Influence of wastewater treatment process on pollution characteristics and fate of microplastics
Researchers investigated microplastic abundance and removal efficiency across four wastewater treatment plants using different treatment technologies, finding influent concentrations between 539 and 1,290 particles per liter that were reduced substantially by primary and secondary treatment. Smaller microplastic particles proved hardest to remove and most likely to persist in final effluent.
Identification and quantification of microplastics in wastewater treatment plant effluent: Investigation of the fate and biological effects
This study identified and quantified microplastics in wastewater treatment plant effluents and sludge, finding particles in all samples with fibers being the dominant type. The research contributes to understanding how much microplastic reaches surface waters via wastewater discharge and how much is captured in sludge that is subsequently applied to agricultural land.
Dynamics of Microfibers Discharged into the Urban and Suburban Environment
Researchers tracked the discharge and environmental fate of microfibers in urban and suburban environments, finding that wastewater treatment effluent and stormwater drainage are primary pathways by which synthetic microfibers enter local waterways.
Microfibres from Textile Industry Effluents
Researchers reviewed the fate of microfibres released from textile industry effluents, finding that conventional wastewater treatment is insufficient to fully remove fibres, which then enter receiving waterways and contribute to environmental microplastic loads.
A Review of the Origins of Microplastics arriving at Wastewater Treatment Plants
This review synthesizes the origins of microplastics entering wastewater treatment plants, examining contributions from household sources, industrial and commercial discharges, and urban surface runoff conveyed through sewerage systems. The authors identify the diversity of microplastic sources reaching treatment facilities as a key challenge for effective removal, with implications for downstream aquatic pollution from treated effluent.
Microplastics in Wastewater by Washing Polyester Fabrics
Researchers investigated microplastic fiber release from polyester fabrics during washing, characterizing the quantity and types of microplastics generated and their potential pathway into wastewater systems as a significant source of environmental microplastic pollution.
Microplastics from textile origin – emission and reduction measures
This paper reviews the emission of fibrous microplastics from synthetic textiles during washing and their pathway through wastewater treatment plants into aquatic environments. It also summarizes available reduction measures such as laundry filters and fiber-releasing fabric design modifications.
Occurrence and analysis of microplastics in municipal wastewater, Poland
Researchers analyzed microplastic contamination in the influent of a large urban wastewater treatment plant in Poland and found an average of about 4 particles per liter. Textile fibers, primarily from clothing, were the most common form of microplastic detected, with polyethylene terephthalate and rubber among the dominant polymer types. The study underscores that laundry and everyday product use are significant sources of microplastic entering the water system.
Microplastics in Wastewater Treatment Plants: Characteristics, Occurrence and Removal Technologies
This review summarizes how wastewater treatment plants are a major pathway for microplastics entering the environment, covering the types, sizes, and sources of microplastics found in wastewater. While treatment plants can remove many microplastics, significant amounts still escape into rivers and oceans through treated water and sludge. The authors evaluate various removal technologies and recommend advanced treatment methods to better prevent microplastics from reaching water supplies.
Quantification and Characterization of Microplastics in Seven Urban Wastewater Treatment Plants
Wastewater treatment plants are a key pathway through which microplastics enter rivers and coastal waters, and this six-month study across seven Spanish treatment plants found that conventional processes offer inconsistent and often inadequate protection. Microplastics were present in all samples, and in some cases effluent concentrations were nearly as high as influent concentrations — meaning the plants were adding little removal value for plastic particles. The dominance of synthetic fibers and the seasonal variation observed point to the need for better tertiary treatment steps to capture microplastics before discharge.
Microplastics in wastewater: State of the knowledge on sources, fate and solutions
This review synthesizes current knowledge on microplastics in wastewater — their sources, fate through treatment processes, and discharge into the environment — and identifies research priorities and potential solutions. The paper serves as a key reference for understanding how wastewater systems contribute to the global distribution of microplastic pollution.
Microplastic contamination in wastewater: Sources, distribution, detection and remediation through physical and chemical-biological methods
This review covers how microplastics end up in wastewater from sources like textile fibers, personal care microbeads, and broken-down plastic debris, and how they often survive the treatment process. Current removal methods like filtration and chemical degradation are costly and not fully effective. The lack of standardized ways to measure microplastics in wastewater makes it difficult to assess the full scope of human exposure through water systems.
Quantification and morphological characterization of microfibers emitted from textile washing
Textile microfibers released during washing machine cycles were quantified and characterized, with the study finding that fiber type, fabric construction, and wash conditions all influenced emission quantities. The results confirm textile washing as a significant and ongoing source of microplastic fiber pollution in wastewater.
Detection and Analysis of Microfibers and Microplastics in Wastewater from a Textile Company
Researchers analyzed microfiber and microplastic levels in wastewater from a textile company, finding that the on-site treatment plant removed only 38–65% of microfibers, meaning up to 62% — including acrylic, polyester, and polyamide particles — can escape into receiving waterways.
Understanding microplastic presence in different wastewater treatment processes: Removal efficiency and source identification
Researchers tracked microplastic removal across different treatment stages at two wastewater treatment plants and found overall removal rates of 90% and 97%. They discovered that population density in the served area was a bigger driver of influent microplastic levels than sewage volume, and that activated sludge served as the primary trap for captured particles. The study identified laundry washing and daily consumer products as the main sources of microplastics entering the treatment plants.
Tracing and Quantifying Microplastics in Bristol’s Urban Water System
Researchers built a mass balance model of microplastic flows through Bristol's entire urban water system and found that households are the primary source feeding the system, while wastewater treatment plants intercept about 99.8% of microplastics before they reach rivers. However, the concentrated microplastics captured in sewage sludge re-enter the environment if sludge is spread on agricultural land as fertilizer. The model provides a template applicable to other cities for identifying where interventions would have the greatest impact on reducing environmental microplastic loads.
Occurrence and Characteristics of Microplastics in a Wastewater Treatment Plant
Researchers sampled the inflow, outflow, and sludge of a Chinese wastewater treatment plant, finding up to 44 microplastic particles per liter in incoming water — mostly polyester fibers. The plant removed about 96% of microplastics, but the remaining fraction was still discharged into receiving waterways.
