Bridgestone brings first at-scale use of recovered carbon black to tire market

On November 20, Bridgestone Americas, Inc. announced the industry’s first at-scale use of recovered carbon black (rCB) in the tire market as part of its long-standing partnership with Delta-Energy Group, LLC.

The move to at-scale commercialization of D-E Black®, Delta-Energy Group’s proprietary rCB product recovered from EOL tires, marks a significant milestone in achieving Bridgestone Group’s long-term environmental vision of targeting 100% sustainable materials – and contributing to a reduction of over 50% CO2 emissions – by the year 2050 and beyond. The process by Delta-Energy Group to extract materials produces 81% less CO2 per ton as compared to virgin carbon black. The investment also serves Bridgestone’s larger mission to drive toward a circular economy that eliminates waste through the continual use of resources, according to the company.

Bridgestone began evaluating Delta-Energy’s materials in 2007 and became an equity partner in late 2014. Since that time, the use of D-E Black as a partial replacement for vCB in new tires has undergone extensive testing to ensure compliance with the high standards and superior quality and performance for which Bridgestone tires are known. To date, Bridgestone has purchased approximately 235 metric tons of rCB, the equivalent of more than 70,000 EOL tires, resulting in the reduction of approximately 765,000 pounds of CO2 emissions, compared to using vCB. By the end of 2020, Bridgestone plans to increase the use of D-E Black to 6,800 metric tons, equivalent to about 2 million EOL tires and a reduction of about 24 million pounds of carbon emissions.

Bob Genovese, Delta-Energy CEO, said in the press release that Delta-Energy has plans to build several more plants in North America over the next few years to produce D-E Black. Bridgestone is using D-E Black in high-quality tires for agriculture and passenger applications across multiple plants in the Americas, including the Bridgestone Des Moines Agriculture Tire Plant, Aiken County Passenger Tire Plant, and the Bridgestone Cuernavaca Tire Plant. The company is currently evaluating new opportunities to expand its usage of D-E Black into additional plants and product lines.
