For Tire Recyclers, a Holy Grail

Carbon Green, a company based in Slovakia, claims to have developed an economically viable method for processing scrap tires using pyrolysis. The company's crucial breakthrough was a nano-scale refinement process that upgrades carbon char to a cost competitive replacement for carbon black, a common reinforcement material used in car and truck tires. Carbon Green's ambitious goal is to open 17 tire processing plants in the next five years, each with the capacity of processing about five million tires per year.
