ABSTRACT:
A method for recycling a used tire constructed of rubber and other materials that does not devulcanize the rubber, comprising the steps of soaking the tire in a composition comprising an organic solvent for a time sufficient to reduce the tensile strength of the rubber by at least about 50%, applying sufficient shear forces to the soaked tire to disintegrate the rubber from the other materials, and sorting the disintegrated rubber from the other materials.
