Although cement is used everywhere throughout the world, many people do not realize that the process to manufacture cement requires very high temperatures over 2,500 degrees Fahrenheit. Cement production involves a closely controlled combination of materials, many of which are found in lime, including calcium, silica, aluminum, iron, and other ingredients. Cement is the fine grey powder that constitutes about 15% of concrete. The remainder of concrete consists of sand and rocks.
Cement plants traditionally use large amounts of coal and other energy sources. However, this changed in 1976 when Giant’s Keystone Bath, PA facility became one of the first kilns in the country to substitute high energy industrial waste for coal. In the 1980s many more kilns began using industrial waste for fuel and in 1991, the Boiler and Industrial Furnace (BIF) Rule began regulating the combustion of hazardous waste in cement kilns to ensure strict adherence to environmental regulations.
Prior to the use of waste as fuel in cement kilns, many of these wastes were burned in incinerators. Burning waste as fuel in the manufacture of cement to recovery energy is a more beneficial green option.
As part of Giant Cement Holdings, Inc., Giant is one of the few environmental organizations to own and operate multiple cement kilns.
Giant Resource Recovery is proud to provide a more sustainable waste-to-fuel option for industrial wastes.
