ASTM announced new standard for tire-derived recovered carbon black
ASTM reports that A new ASTM International standard will encourage the consideration of the entire life cycle of tires by providing a classification system for recovered carbon black (rCB). The new standard (D8632) was developed by ASTM’s recovered carbon black committee (D36). "Recovered carbon black is a semi-reinforcing filler obtained from post-consumer rubber products such as tires and conveyor belts,” says ASTM member Jorge Lacayo-Pineda. “Through various thermal decomposition processes, the feedstock is converted into oil, gas, and raw rCB. After subsequent post-processing steps, the final product is rCB.”
