In this application, scrap tires are used as a cleaner and more economical alternative to coal as fuel in cement kilns, pulp and paper mills and industrial and utility boilers. They are combusted as whole tires particularly in cement kilns or as 2” wire free chips in cement kilns other boilers. Tire derived fuel (TDF) has more BTUs than a comparable weight of coal, and since tires are manufactured in part with natural latex which literally grows in trees, TDF has a lower greenhouse gas impact than coal. TDF accounted for about 1922 thousand tons of scrap tires in the U.S. in 2015, or about 48.6 percent of the total scrap tires generated. Due to increasing fuel prices and improvements in the quality and reliable delivery of TDF, this market is anticipated to experience strong demand in the immediate future. Past history has shown this market has room to grow.
