Crumb Rubber Technology Inc. has developed a cryogenic scrap tire recycling machine it claims processes the tires without using chemicals. The CRT-1 System is a single-pass, four-phase system that results in scrap tires being converted into crumb rubber, steel and fiber.
The technology took more than four years to develop and the machine is just now available, said Michael Reali, one of the three partners in Jamaica, N.Y.-based Crumb Rubber Technology.
The first phase involves shredding whole tires into 2-inch by 2-inch rubber chips. In the next phase, the chips are cryogenically cooled to -130§C, using natural air and no chemicals.
After that, the chips are pulverized into rubber, steel and fiber. In the final step, the materials are classified by product and size.
The whole system takes just three people to operate and users of the machine would regain their investment in less than one year, Reali claimed.
