A process for disposal of scrap tires was developed in which the shredded tires are pyrolyzed in an indirectly heated rotary kiln at 600/sup 0/C to produce mainly fuel oil and char. The operating temperature was determined as the temperature which produces the char that gives carbon black with optimum properties as reinforcing filler for rubber. The oil is condensed in two stages. The gas is used with light oil to heat the kilns. Cost estimates for 4000-14,000 ton/yr plants, balanced against credit for recovered materials and the cost of collecting and transporting scrap tires show an optimum plant size of 7000 tons/yr. A demonstration plant of that size is under construction.
