ETRA, the European Tire Recycling Association, has issued a document to European Chemical Agency (ECHA) responding to the question surrounding the use of tire crumb rubber infill in artificial turf.
The main argument against the use of crumb rubber infill is that it contains a number of potentially harmful chemicals. However, these chemicals are not “biodegradable”, which means that they are not released in contact with water or air or skin, ETRA’s statement said.
ETRA has responded that since the larger particles of rubber used in infill are not subject to road abrasion to create dust, there is less likelihood that there could be the same exposure to particles in the air. If there are polyaromatic hydrocarbons (PAHs) in the air, these are due to vehicle or combustion pollution, not a release from crumb rubber granulate.
Furthermore, ETRA points to research that shows that the crumb rubber infill is not exposed to solvents that would degrade the crumb rubber pellets and release contaminants in contact with human skin. For this reason, there is no risk, ETRA’s statement said.
Despite the lack of risk from PAHs contained in crumb rubber granulate, these chemicals have, in fact, been banned from tires manufactured in the European Union since 2010, ETRA said.
