Environmental impacts of artificial turf: a scoping review

Abstract

AbstractArtificial turfs represent a large environmental issue in terms of waste, microplastic pollution and leaching of chemicals. Artificial turfs are made of several components, the shock absorbing pad, backing, stabilizing infill, performance infill and artificial grass fibers. Common for these, except the stabilizing infill, is being made of plastic and chemicals being released to the environment. The purpose of this article is to investigate current research on the environmental impact of artificial turfs for football fields. This is done by presenting the state-of-the-art through a review of 40 articles and grey reports. Studies concerning the chemical content of rubber granules and microplastics lost to the environment represent most of the findings. The methods applied vary to a great extent, and more research is needed to further understand the environmental impact of artificial turfs. This study provides an overview of the previous work performed and highlights knowledge gaps and will be of help during further research on the environmental impacts of artificial turfs.
