Recycled Tires (Ground Rubber)
Ground rubber — also called “tire crumb” or “crumb rubber” — is recovered from scrap tires or from the tire retreading process. It is used in road construction and in a number of athletic and recreational applications, including ground cover under playground equipment, running track material, and as a soil additive on sports and playing fields.
Crumb rubber is often used in synthetic turf fields as “infill” between turf fibers to provide stability, uniformity and resiliency to synthetic turf fields. Synthetic turf was developed in the mid-1960s and has since gained widespread popularity around the country. Synthetic turf was originally used in stadiums and on athletic fields for college and professional sports teams, but now is also used in municipal parks, golf courses, playgrounds, cruise ships, and airports. There is also a growing residential market.
According to the Synthetic Turf Council, synthetic turf has been installed in approximately 4,500 U.S. fields, tracks and playgrounds.
Recycled rubber can be used at levels as high as 50 % in manufacturing new tires.
There are approximately 275 million scrap tires in stockpiles in the U.S.
