Risk Management Measures (RMM) refer to strategies, mechanisms and practices implemented to reduce the environmental impact of artificial turf fields, particularly focusing on practically eliminating the dispersal of microplastics and rubber granulates into the surrounding environment.

The dispersal of microplastics from artificial turf fields can potentially contribute to environmental pollution if in sensitive natural areas. Microplastics can enter soil, water bodies, and the broader ecosystem.

The research conducted at Silkeborgbanen (EU), Princeton, and Cardigan Mountain demonstrated that the height of barriers around the turf significantly impacts the retention of rubber granulates. Higher barriers, particularly those at 24 inches (60 cm), were found to effectively eliminate dispersal, reducing it to approximately 13 lbs per pitch per year (6 kg per pitch per year), with further reductions observed when considering the off-pitch removal of granulates from players' shoes.

Player activity, particularly the accumulation of granulates in shoes, and the use of maintenance equipment, such as tractors, can contribute to the dispersal of microplastics. The research found that proper management, including cleaning protocols, can significantly reduce these dispersals. For example, dispersals from maintenance equipment were minimal at only 0.44-0.88 lbs/pitch/year (0.2-0.4 kg/pitch/year).

The study at Silkeborgbanen (EU), Princeton and Cardigan Mountain found that drainage systems were effective in preventing the release of microrubber into the environment. No significant contamination was detected in the drainage water, and PFAS levels were within safe limits according to strict Danish environmental standards.

The findings from Silkeborgbanen (EU), Princeton and Cardigan Mountain align with earlier European research, such as the Ecoloop Kalmar report, confirming that proper RMM can effectively prevent the dispersal of microplastics. These studies collectively reinforce the idea that with the right measures, artificial turf fields can be managed in an environmentally responsible and sustainable way.

Cardigan Mountain School and Princeton University both participate in testing and implementing RMM on their artificial turf fields. Their involvement helps to confirm the effectiveness of these measures, building on the findings from European studies and contributing to a broader understanding of sustainable practices for artificial turf in North America.

The research suggests that other artificial turf installations can significantly reduce their environmental impact by adopting similar RMM strategies. This includes using higher barriers around the fields, implementing proper maintenance protocols, and ensuring effective drainage systems to prevent microplastic dispersal.

These findings set new standards for the design, construction, and maintenance of artificial turf fields. By demonstrating that microplastic dispersal can be effectively managed, this research supports the broader adoption of environmentally friendly practices, paving the way for more sustainable sports facilities worldwide.
