RETRACTED: Organic composts as A vehicle for the entry of microplastics into the environment: A comprehensive review

AI summary Read the abstract

This retracted review examined how organic compost can introduce microplastics into agricultural soil, finding that compost contained up to thousands of microplastic particles per kilogram. The microplastics in compost come from plastic packaging fragments, synthetic fibers, and other contaminants in the source waste. While the paper was retracted, the underlying concern remains valid: composting may be an overlooked pathway for microplastic contamination of farmland.

Microplastics in MSW-derived compost: release rate, characteristics, ecological risks, and mitigation strategies for sustainable agriculture

AI summary Read the abstract

Compost made from household trash often contains tiny plastic bits called microplastics, and surprisingly, the compost from industrial facilities had even more plastic contamination than the raw waste it started from. Since this compost gets spread on farm fields, these plastic fragments can build up in the soil where our food grows. The good news: simply sorting out plastic from food/organic waste before composting (rather than mixing everything together) dramatically cuts down on this contamination, suggesting better recycling habits at home and in waste facilities could help keep microplastics out of our agricultural system.
