Tire Derived Aggregate (TDA) consists of scrap tires cut into pieces that have a basic geometrical shape that vary in sizes between 2 inches and 12 inches, and are intended for use in civil engineering applications. TDA has been gaining popularity in many application over gravel because of its: Lightweight (with 1/3 of gravel), thermal insulation (8 times better than gravel), drainage (10 times better than gravel), and low cost. TDA is comparable in price to gravel per ton but contains three times the volume.

Tire Derived Fuel (TDF) can be used as a substitute energy source for coal, oil, and natural gas. TDF is used in cement kilns, power plants, and pulp and paper mills around the world. When used as an alternative fuel, TDF produces 25% more energy than coal – generating up to 15,000 BTU/lb, and is cleaner than coal with emissions lower than most coals; particularly high sulfur.
