Fuel derived from waste tires, including altered, shredded, or whole tires, is known as tire-derived fuel (TDF). When burned, tires generate the same amount of energy as oil; 25%–50% more energy than coal, and 100%–200% more energy than wood. The EPA and state-testing facilities have shown that TDF produces low emissions compared to other conventional fuels. At well-controlled facilities, emissions are considerably less when TDF is used to replace some of the typical fuels used at the facilities.
