Innovative method to incorporate a devulcanization aid into rubber
Over the past decade, rubber recycling has become a topic of great interest. In the European Union alone over 300 million end-of-life tires are discarded yearly, but this material can be recycled and reused. Various devulcanization technologies were developed to produce a high-quality recycled rubber from end-of-life tires; however, one of the main challenges remains to distribute the devulcanization agent equally within the rubber matrix. Within this study, an innovative technology was developed based on the incorporation of the devulcanization agent at an earlier stage during the production of the rubber product and activation in the thermomechanochemical devulcanization process.
