    We developed a two-step batch devulcanization tech-nique using a two-roll mill and an internal mixer, both of which are widespread technologies in the rubber indus-try. We performed devulcanization experiments on two almost identical EPDM rubber mixtures: one vulcanized with a sulfur-based, the other vulcanized with a peroxide-based system
