Plastics and other extraneous matter in municipal solid waste compost: A systematic review of sources, occurrence, implications, and fate in amended soils
Researchers reviewed contamination in municipal compost made from household organic waste, finding plastics are the most prevalent pollutant — with some batches containing enough plastic to deposit over 500 kg per hectare of farmland each year. Repeated use of contaminated compost builds up microplastics in soil, threatening soil health and potentially moving plastic particles into crops and food.
Microplastic Abundance in the Locally Produced Commercial Compost and the Characteristics
Researchers measured microplastic abundance in locally produced commercial compost, characterizing particle morphology, size, and polymer type. The compost contained measurable microplastic concentrations dominated by polyester fibres and polyethylene fragments, confirming that commercial composting does not eliminate microplastic contamination and may serve as a route for soil plastic input.
A systematic review of the occurrence of microplastics in compost: Understanding the abundance, sources, characteristics and ecological risk
Researchers reviewed 19 global studies and found microplastics in virtually all types of compost — including those made from animal manure, sewage sludge, and municipal waste — with concentrations reaching up to 288,000 particles per kilogram in some samples. Since compost is widely applied to farmland, these findings highlight a significant but overlooked pathway for microplastics to enter soils and the food chain.
Identification and Quantification of Microplastics in Commercial Compost From a Wide Range of Composting Materials and Potential Environmental Impacts
Researchers identified and quantified microplastics in commercial compost derived from household waste, livestock manure, and vegetable straw using acid extraction, filtration, and FTIR spectroscopy. All compost types contained microplastics, with concentrations varying by feedstock type, raising concerns about microplastic introduction to agricultural soils via compost application.
Unveiling the abundance and potential impacts of microplastic contamination in commercial organic fertilizers/compost produced from different solid waste
Researchers analyzed commercial organic fertilizers made from different waste sources and found microplastics in 80% of the samples, with compost from mixed municipal waste containing the highest levels. The estimated amounts of microplastics being introduced into agricultural soils through these fertilizers exceeded previous reports. The study highlights the need for stricter regulations on organic fertilizer quality to prevent microplastic contamination of farmland.
Microplastic pollution and the related ecological risks of organic composts from different raw materials
Researchers analyzed microplastic contamination in 124 organic compost samples made from livestock manure, poultry waste, crop straw, and solid waste, finding that all types contained significant microplastic loads. Solid waste compost had the highest levels while crop straw compost had the lowest, and the particles showed signs of weathering and mineral attachment. The findings suggest that applying organic compost to farmland may be an underappreciated source of microplastic pollution entering agricultural soils.
Breakdown of plastic waste into microplastics during an industrial Composting: A case study from a biowaste facility
A study of industrial composting facilities found that plastic waste items introduced into the compost feedstock broke down into microplastics during the composting process, with finished compost containing significant MP concentrations that could contaminate agricultural soils where the compost is applied.
The dynamics of macro- and microplastic quantity and size changes during the composting process
Researchers tracked microplastic generation during composting at two Austrian facilities, finding that microplastics appear after the first turning event and increase throughout the process, with shorter turning intervals accelerating fragmentation rates.
Macro- and microplastics in composts from municipal solid waste industrial composting Plants in Uganda
Researchers quantified macro- and microplastic contamination in composts from two industrial municipal solid waste composting plants in Uganda, finding substantial plastic contamination resulting from minimal source separation in waste collection, which could transfer plastics to agricultural soils.
Identification and Quantification of Microplastics in Compost: A case of landfills in Uganda
Researchers surveyed compost sites across 8 cities and 5 municipalities in Uganda, finding microplastics at all locations with fibers being the most abundant type (54.98%), indicating that poor waste management practices are driving plastic contamination into compost used in agriculture.
Quantification and Characterisation of Microplastics in Organic Waste-Derived Soil Amendments
Researchers quantified microplastics in Scottish compost, anaerobic digestate, and biosolids used as soil amendments, finding contamination in all samples at concentrations of 34 to 160 particles per gram. Biosolids contained the highest levels, dominated by high-density fibers likely from textile washing, along with over 20,000 cellulosic microfibers per gram. The findings suggest that applying these organic amendments to agricultural land could introduce substantial quantities of microplastics into soil.
Microplastic in Australian processed organics: Abundance, characteristics and potential transport to soil ecosystem
Researchers analyzed processed organic waste products from 11 facilities across Australia and found microplastics in every sample, with concentrations ranging from 1,500 to 16,000 particles per kilogram. They estimated that billions to trillions of microplastic particles could be transferred to Australian soils annually through the application of compost and biosolids. The findings highlight that recycling organic waste, while beneficial for waste reduction, may inadvertently spread microplastic contamination to agricultural land.
Microplastic contamination of soil: Are input pathways by compost overridden by littering?
Researchers investigated whether compost application is a major pathway for microplastic contamination of agricultural soil using a long-term fertilizer trial. The study found that while compost does contribute microplastics, the levels detected were relatively low compared to microplastics from general littering, suggesting that environmental littering may be a more significant source of soil microplastic contamination than composting.
The Extraction and Characterization of Microplastics of Biocompost and Water Samples Collected from the Different Semi-Urban Agronurseries
Researchers analyzed biocompost and water samples from semi-urban plant nurseries and found microplastic contamination in all samples, with fibers and fragments being the most common types. The microplastics came primarily from plastic packaging and materials used in the composting process. The findings suggest that compost intended for agricultural use may be an unintended source of microplastic pollution in soils.
