DUSTING OFF THE FACTS ABOUT CEMENT KILNS
Your article on Dean L. Buntrock's efforts to revitalize WMX Technologies Inc. ("Cleaning up after Waste Management," The Corporation, Jan. 24), may accurately reflect the comeback strategy of a great entrepreneur. But it misrepresents the facts on cement kilns that burn hazardous waste as a supplemental fuel.
Cement kilns are, indeed, the leading competitors of commercial hazardous-waste incinerators like those WMX operates. But cement kilns must comply with environmental rules that are often more stringent than those for incinerators.
Regarding cement-kiln dust (you incorrectly labeled it ash), your assertion that it is unregulated is wrong. Cement-kiln operators are subject to numerous state and local cement-kiln-dust standards. Further, cement kilns that recover energy from hazardous waste are also required by federal law to test the dust to determine whether the dust is different from nonwaste-burning kiln dust.
