A new material recycling technology for crosslinked rubber was developed using continuous reactive processing methods. In the process of producing reclaimed rubber, breakage of crosslinking points in the crosslinked rubber occurs selectively under the controls of shear stress, reaction temperature, and internal pressure in a twin screw extruder, corresponding to the dynamic devulcanisation process. Deodorisation during the process has also become possible by a newly developed method. The reclaimed rubber based on rubber waste generated from both automobile manufacturing products and post-consumer products shows excellent mechanical properties applicable to new rubber compounds. Furthermore, an enhanced rubber recycling process, including both dynamic devulcanisation and dynamic vulcanisation, for producing TPE (thermoplastic elastomer) based on rubber waste has been established. The obtained TPE exhibits highly recoverable rubber elasticity and mechanical properties comparable to commercial TPE. It is expected that the rubber recycling technology developed and presented in this study will contribute to protecting the environment and also saving of resources.
