MARIS has designed and patented a new two-step devulcanization process to produce devulcanized rubber with very high-quality standards. By “devulcanization” we mean a process of selective breaking of the S-S and C-S bonds of the elastomer which causes only a limited degradation of the polymeric structure (C-C bond).

According to expert opinion in the tire recycling industry, BlackCycle – the research project coordinated by Michelin – can revolutionize end-of-life tire recycling worldwide. This opinion was voiced by experts during a meeting of the Bureau of International Recycling (BIR) at its Tires & Rubber Committee on October 15, 2020. There was tangible excitement at the BIR Tyres & Rubber Committee webinar on October 15 following a guest presentation on the recycling of end-of-life tires (ELTs) into secondary raw materials for tires and other product applications.

Despite hard efforts of the tire recycling and pyrolysis industry to develop new markets and increase recycling rates, recycled rubber based product markets demonstrate only moderate growth. To tackle the problem and allow thousands of tons of precious materials go back to consumer goods, numerous end-of-life tire management organizations, companies and research labs do their best to find new markets and develop innovative products out of scrap tire rubber.
