                Growing markets for scrap tires. (scrap tire recycling) Michael 
                Blumenthal. 
            Abstract: An increasing number of recycling plants are using scrap 
            tires to produce useful end products for civil engineering and fuel. 
            Three-quarters of all scrap tires produced in 1996 were recycled, 
            according to the Scrap Tire Management Council. Tire-derived fuel is 
            used in a number of manufacturing facilities such as cement kilns 
            and paper mills. Twelve million spare tires are used in the 
            production of ground rubber. The industry has encountered a number 
            of problems but is likely to continue to expand.
