Cement kilns that substitute hazardous waste-derived fuels for a portion of the required fossil fuels are currently `under the gun` to minimize certain airborne emissions - specifically, dioxins and metals. Historically, it has been assumed that emissions of dioxins and furans (referred to collectively as `dioxins` in this article) and metals from cement kilns vary depending on operating conditions. Recent test results tend to confirm the assumption that dioxin emissions may be controlled by varying the operating conditions in a cement kiln. Metals emissions, on the other hand, do not appear to be affected by different operating parameters. Metals removal efficiencies seem to fall within a narrow range at all cement kilns that burn hazardous waste, apparently due to the inherent properties of the cement manufacturing process. This article summarizes test results for dioxin and metals emissions from a number of cement kilns operating in the United States. 2 refs., 3 tabs.
