Cement kiln dust (ckd) is a waste product that accumulates at the rate of 12 million tons per year in the United States. In proposed hazardous waste guidelines in 1978, the Environmental Protection Agency (EPA) placed ckd in the "special wastes" category pending more information on the composition, characteristics, and degree of hazard posed by this waste. In 1980, the special wastes category was removed, but a 3-year study of the hazard potential of ckd has been proposed by EPA. An exploratory evaluation of the resource recovery potential and environmental effects of the metals present in the dust has been underway during this period at the Bureau of Mines Avondale Research Center. Results of the first phase of this research--ckd from the east coast--will be discussed including major, minor, and trace element concentrations; mineralogy; iron chromatographic and thermal information; and EPA hazardous waste leach test results.
