Is There a Known Process to Devulcanize and Revulcanize Rubber?

[ufarad]

Does there exist a known process to devulcanize rubber (i.e., getting out all the sulfur crosslinks from the polymer chains) and get out of the process rubber that can be revulcanized? Or does one big slash on a tire mean that 20-30 pounds of rubber can never be used for making tires again?

It'n not necesary to devulcanize the rubber for revulcanized again.
cut the tire in samll pieces and put in a mold. Vulcanize again a hot temperature and finish.
