How to handel scrap tires for cement kiln firing

The use of scrap tires as a supplemental fuel in the United States Portland cement industry has increased significantly in the past six years. In 1990, there were two kilns using tire-derived fuel (TDF), today 30 kilns use TDF. The outlook for continued and expanded use of TDF in the U.S. cement industry should be considered favorable, with 15
