The report gives results of a study of the management and disposal of residues from environmental control facilities in the steel industry. Information from 13 integrated U.S. steel mills is compared with that found in the literature and with data collected during visits to English, German, and Japanese steel mills, technical and industrial associations, and government agencies. Methods used to recycle dusts and sludges and to regenerate or recover waste acids and oils are covered. Of the approximately 16.6 million tons of residues, 9.1 million tons are recycled, and 7.5 million tons are dumped or stored for later reuse. The pollution control facilities used and the quantities and properties of the residues generated in various processes are described. In 1974, the U.S. steel industry produced over 145 million net tons of raw steel. During the same period, over 16 million tons of pollution abatement residues were generated by the industry in 14 different iron and steelmaking subcategories, not including iron and steelmaking slags.
