A process for producing reclaimed rubber has the steps of: mixing waste vulcanized rubber with unvulcanized new rubber and a devulcanizing agent; and kneading the resulting mixture in a heating atmosphere for mastication of the unvulcanized new rubber and simultaneously reclamation of the waste vulcanized rubber. Furthermore, the obtained unvulcanized reclaimed rubber can be vulcanized with a vulcanizing agent.
