ClearConcept development of granular traps : A study to reduce the spread of microplastics from artificial turf
This Swedish engineering thesis developed a concept for granular traps to prevent microplastics from artificial turf sports fields from spreading to surrounding environments via stormwater runoff. Tire crumb rubber and artificial turf infill are major sources of microplastic pollution in urban waterways.
Fate of recycled tyre granulate used on artificial turf
Researchers reviewed the environmental fate of recycled tyre rubber granulate used as infill on artificial turf fields, finding that while the material provides significant CO2 savings compared to alternatives, dispersal of approximately 3,000-5,000 kg per field per year to surrounding environments raises microplastic pollution concerns.
Dynamic probabilistic material flow analysis of rubber release from tires into the environment
A dynamic material flow analysis model estimated the annual and cumulative release of rubber from vehicle tires into the environment via road wear, finding that tire rubber represents a substantial fraction of total microplastic pollution in terrestrial and aquatic systems. The study helps quantify this important but often overlooked microplastic source.
Tyre granulate on the loose; How much escapes the turf? A systematic literature review
Without mitigation measures, an average artificial football turf loses approximately 950 kg/year of tire rubber infill to the environment, with snow removal adding up to 830 kg/year more. The most effective reduction strategies target snow clearing, mechanical brushing, and granulate carried off by players.

Mechanisms of Generation and Ecological Impacts of Nano- and Microplastics from Artificial Turf Systems in Sports Facilities
This review examines how artificial turf in sports facilities generates nano- and microplastics through mechanical wear, UV radiation, and weathering of synthetic grass fibers and infill materials. These plastic particles have been detected in drainage systems and surrounding soils near sports facilities, with laboratory studies showing harmful effects on soil organisms and aquatic life. The findings highlight artificial turf as an overlooked but significant source of microplastic pollution in urban environments.

The dark side of artificial greening: Plastic turfs as widespread pollutants of aquatic environments.
This study found that artificial turf fibers made of polyethylene and polypropylene are widely present in river and ocean waters, having been transported there by stormwater runoff from sports fields, gardens, and rooftops. The findings reveal artificial turf as an underappreciated and widespread source of microplastic fiber pollution in aquatic environments.
Mapping Plastic and Plastic Additive Cycles in Coastal Countries: A Norwegian Case Study
Researchers developed a comprehensive method using dynamic probabilistic material flow analysis to map the entire plastic cycle in Norway, including 232 plastic additives. For the first time, they modeled the progressive leaching of microplastics during the use phase of consumer products. The study provides a detailed picture of how plastic polymers and their chemical additives move through coastal economies and eventually reach the environment.

Researchers constructed a global mass budget and box model tracking plastic polymer flows from production through fragmentation into microplastics across land, ocean, and atmosphere.
