The Cement Kiln Recycling Coalition is a national trade association representing all the cement manufacturers in the U.S. that recycle the value in energy-bearing hazardous wastes by using them as fuel in kilns that produce Portland cement. CKRC also represents companies that collect, process, manage, and market waste-derived fuels for use in cement kilns.

Cement kilns that burn hazardous waste for energy recovery are among the most highly regulated combustion units in the world. Kiln operators have conducted extensive emissions tests to comply with these regulations, and have performed detailed site-specific risk assessments that have proven the safety and efficacy of using secondary materials as fuel in cement kilns.
