Executive SummaryBridgestone and Mi

Executive SummaryBridgestone and Michelin collaborated with recovered carbon black (rCB) suppliers and other stakeholders in the value chain to define initial proposals for standards, including grades, specifications, and awareness of quality and performance requirements for the tire industry. The two companies have produced a set of definitions, proposed specifications, and guidelines for regulatory requirements, as well as a foundation for supporting the growth of the rCB industry. While the focus markets for this phase were Europe and North America, the principles of the work can be scaled globally. Bridgestone and Michelin plan to continue developing a point of view on factors impacting consistency, in-rubber properties, and environmental impact to inform standardization efforts in the rCB industry and will also continue to advance and scale sustainable carbon black technologies to achieve a shared vision of a sustainable supply chain in 2050. This will include rCB and other pathways, such as carbon black produced from renewable oils or tire pyrolysis oil. Bridgestone and Michelin acknowledge the feedback and input from many stakeholders who contributed to the development of this white paper.
