Did you know?

A 2013 study by the Society for Risk Analysis demonstrated that for the products and fields tested, exposure to infill and artificial turf was generally considered de minimus.

Product Safety/Mulch Research Studies

Innovative. Safe. Liberty Tire Recycling is at the forefront of a growing trend in the marketplace. We produce recycled rubber that is transformed into a wide variety of smart, reusable products that promote safety. You can find them in places such as professional sports stadiums and in children’s playgrounds. We are committed to making sure that our solutions to the environmental problem of tire waste do not create other environmental or health problems, and therefore, closely monitor scientific research related to our products. Here are examples of recent studies that have been conducted on the safety of these products.

Environmental and health impacts of artificial turf: a review.

This 2014 review of available studies examines the environmental and health impacts of artificial turf. Air quality and field drainage were found to be within or below regulatory limits and local background amounts, with a preliminary life cycle assessment suggesting that environmental impacts were lower than equivalent grass fields. Health risk assessments suggested that users were not exposed to elevated risks.

A Scoping-Level Field Monitoring Study of Synthetic Turf Fields and Playgrounds

A 2009 U.S. Environmental Protection Agency study examined health risks to people who breathe the air above synthetic turf that contains crumb rubber. The study analyzed chemicals found in the air above the turf and upwind from the turf fields. The chemicals were found in similar concentrations in both samples. On average, concentrations of components monitored were below levels of concern.

Artificial Turf Football Fields: Environmental and Mutagenicity Assessment

In this 2013 study, no significant differences were found between chemical concentrations at an urban site and on a turf football field, both during warm and in cold seasons, either with or without on-field activity. On the basis of environmental monitoring, the study concluded that artificial turf football fields presented no more exposure risks than the rest of the city.

Bioaccessibility and Risk of Exposure to Metals and SVOCs in Artificial Turf Field Fill Materials and Fibers

This 2014 study evaluated potential exposures from playing on artificial turf fields and associated risks to chemicals by examining artificial turf fibers, types of crumb rubber infill and samples from actual fields. The study showed that for the products and fields tested, exposure to infill and artificial turf was considered lacking any significance.

Safety Study of Artificial Turf Containing Crumb Rubber Infill Made From Recycled Tires

The California Department of Resources Recycling and Recovery evaluated artificial turf athletic fields containing recycled crumb rubber infill. This 2010 study indicated no relationship between surface temperature and chemical concentrations detected above artificial turf fields, and there were lower numbers of bacteria detected on artificial turf relative to natural turf.

Review of the Human Health & Ecological Safety of Exposure to Recycled Tire Rubber found at Playgrounds and Synthetic Turf Fields

This 2013 literature review of available studies concluded that adverse health effects are not likely for children or athletes exposed to recycled tire materials found at playgrounds or athletic fields. Similarly, no adverse ecological or environmental outcomes from liquid that drains from landfills (leachate) are likely.
