Bridgestone begins manufacturing tires with recovered carbon black
Bridgestone has a long-standing partnership with Natchez, Miss.-based Delta-Energy Group L.L.C. and is using Delta-Energy's proprietary product, D-E Black, as its sole source of rCB in Des Moines, Bridgestone said in a Nov. 20 press release. D-E Black, like all rCBs, is recovered from scrap tires and retains a structure similar to that of virgin carbon black, allowing it to be used as a partial replacement for virgin black in tires, the tire maker said. Delta-Energy's patented, catalyst-driven DEPolymerization process is the first to produce rCB that has commercial market application for reinforcing rubber compounds, according to Bridgestone. The deal with Delta-Energy marks a significant milestone in Bridgestone group's long-term commitment to using 100 percnt sustainable materials and reducing carbon dioxide emissions by more than 50 percent by 2050, the company said.
