Carbon black production from waste tires

In 1997, Svedala began a program to develop a process to convert waste tire s into valuable commodities. A review of numerous approaches revealed short comings that were process related or mechanical related, while some of the approaches emphasized the production of low-value products. A market study revealed that a process that could produce a good grade of carbon black wou ld be economically feasible. This paper discusses the laboratory and pilot- plant development and commercial plant design of such a process.
