Piling it on

The use of scrap tire piles in solid waste management is discussed. Tire-derived fuel (TDF), civil engineering applications and ground rubber are growing applications for scrap tires. According to Rubber Manufacturers Association (RMA), Washington, D.C., civil engineering applications involving land fill construction have helped to use 35 million of the 40 million tires used in the area in 2001. Shredded scrap tires can be used in leachate liners, gas-venting systems, cap closure material, operational liners and as a daily cover when mixed with dirt.
