Crumb rubber is a type of infill made up of grinded vehicle tires, which is the most common infill in synthetic (or artificial) turfgrass. The infill is used to help keep hardiness of the sew fibers. It is a similar process to what sand does for the natural turfgrass (Synthetic Turf Council).
But what is the issue relating to crumb rubber infill? Is there any alternative to use a different infill for synthetic turf?
Issue with Crumb Rubber Infill
There has been concern from the public and athletes about the use of recycled crumb rubber in synthetic turf. Recently, there has been an increase of people getting cancer who have played on the synthetic turf and are accusing the crumb rubber infill for the cancer. Currently the EPA, CDC, and other federal agencies are investigating the connection of cancer and the crumb rubber use in synthetic turf (EPA). Schools and other places that use crumb rubber have removed their synthetic fields or changed the infill due to the possible risk.
Depending on the company that installs the synthetic turf field, there is other alternative infills that can be used for synthetic turf. Examples include:
- Silica Sand
- Coated Rubber Infill
- Coated Silica Infill
- TPE Infill
