Jämförelse av alternativa fyllnadsmaterial till konstgräsplaner
AI summary Read the abstract
This study evaluated and compared multiple alternative infill materials for artificial football pitches to address the environmental impact of rubber infill, which has been identified as Sweden's second largest source of microplastic emissions. Analysis including GC-MS and XRF testing found that at least three alternatives (Envirofill, Safeshell, and Geofill) were more environmentally friendly, equal in play performance, and comparable in cost to EPDM rubber infill.
The use of artificial football pitches have expanded rapidly in recent years due to its substantial benefits over natural grass fields. Increased playing hours and decreased maintenance costs are often cited as the main benefits, but to achieve necessary performance rubber infill material is used. The environmental impact of this rubber infill has been studied, the migration of rubber infill granules was determined as Swedens second largest source of microplastic emissions (Magnusson K. et al, 2015). To circumvent the problems caused by rubber infill, alternative infill materials has been considered as a solution. This study aims to evaluate and compare several alternative infill materials already present on the market. The comparison is based on ten separate criteria. To gather the information needed for evaluation contact has been made with producers and industry experts, coupled with GC-MS and XRF analysis of three materials included in the comparison. The results found that at least three different alternative infill materials were more environmentally friendly, equal in play performance and comparable economically to EPDM rubber infill: Envirofill (Acrylic-coated sand), Safeshell (Walnut) and Geofill (Coconut-cork mix).

This Swedish investigation quantified the spread of rubber granulate infill from two artificial football fields in Svedala municipality, measuring how these tire-derived microplastics disperse into surrounding soils and waterways — important given that artificial turf is identified as Sweden's second-largest microplastic source.
Fate of recycled tyre granulate used on artificial turf
AI summary Read the abstract
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.

This review examined the health and environmental risks posed by styrene-butadiene rubber (SBR) infill granules in third-generation synthetic sports pitches. The authors found that athletes are exposed to microplastics and carcinogenic compounds from rubber crumb, and reviewed green chemistry alternatives that could replace conventional infill while maintaining pitch performance.
