Bio-soot & carbon-black replacement
Two distinct, honestly-different routes displace virgin fossil carbon black in rubber and tires: a genuinely bio-based one, where Canada's FPInnovations converts kraft-pulping black liquor (lignin) into a carbonaceous rubber filler via hydrothermal carbonization, restoring over 60% of mechanical strength when carbon black is cut by 15%; and a circular, tire-derived one — not biological in origin but displacing the same virgin fossil-carbon-black demand — where Cabot Corporation's EVOLVE and Orion Engineered Carbons' ECORAX Circular convert end-of-life-tire pyrolysis oil into ISCC PLUS mass-balance-certified reinforcing carbon, Birla Carbon's Continua turns tire-pyrolysis solids directly into finished carbonaceous material, and India's Epsilon Carbon sells Terrablack, a recovered-carbon-black line claiming 40-50% lower global warming potential than virgin carbon black.
