DUNLOP & Cabot sign MoU for adoption of circular reinforcing carbon

Cabot Corporation announced today that it has signed a Memorandum of Understanding with DUNLOP (Sumitomo Rubber Industries) to evaluate the commercial adoption of circular reinforcing carbons made with Cabot’s regenerated carbon technology. These materials are part of Cabot’s EVOLVE Sustainable Solutions and incorporate reclaimed carbon derived from the pyrolysis of end-of-life tires. Sumitomo is evaluating the circular reinforcing carbons as sustainable raw materials for its tire production. Under the agreeent, Cabot will focus on scaling regenerated carbon technology to meet anticipated market demand.

The adoption of sustainable raw materials is part of Sumitomo Rubber’s effort to realize the circular economy concept for its tire business, known as "TOWANOWA". This concept consists of two interconnected rings: the "Sustainable Ring," which covers five processes across the value chain, and the "Data Ring," which integrates big data collected from each process. By sharing and utilizing data between these rings, Sumitomo Rubber aims to deliver new value. Based on this concept, Sumitomo Rubber has been actively promoting the use of sustainable materials and other initiatives to reduce its environmental impact.
