Scrap tires have been a source of ground rubber since 1992. This resource also is called crumb rubber.
Crumbs are used to make:
Ball-point pens, wallets, women’s fashions and other consumer products
rubber-modified asphalt, used primarily in California and Arizona
new tires
picnic tables and other molded products
sheets of rubber for flooring and mats
soaker hoses and other bound products
soil amendments for playgrounds and horse arenas
Another use of scrap tires is Tire-Derived Fuel (TDF), a process where whole tires are burned in facilities such as cement kilns, pulp and paper mills, and industrial and utility boilers.
In the U.S., about 33 million scrap tires per year are processed into crumbs. A total of 115 million tires per year are burned as TDF. Unfortunately, those numbers are only slightly more than half the 281 million scrap tires generated each year.1
