ABSTRACT:
A process for recycling rubber, elastomers, and thermoset materials in which the material to be recycled is pulverized in a manner which maintains the chemical composition of the material, producing a powder. The powder is introduced into a mold which is heated to a temperature of at least about 200.degree. C. and a compression force of at least about 10 tons is applied to the powder for a period of at least one hour, resulting in formation of a single piece of the rubber, elastomeric, or thermoset material, with no change in chemical structure.
