Chemetco was formerly one of the largest United States refiners of copper from recycled or residual sources. Its maximum output of 120,000 tons per year was approximately half of the entire U.S. copper output from so-called "secondary copper refining." The company website described Chemetco as one of the world's largest copper refiners and reported an estimated revenue in 1999 of $500 m.〔Bye,Connie. "(150 Largest Privately-held Companies )" (2000, March). St Louis Business Journal.〕 It was listed in 2000 as the 23rd-largest privately held company in the United States.〔 The company had a history of environmental problems over its entire career, along with problems managing its wastes and by-products.〔''(Health Consultation, Chemetco, Hartford, Madison County, Illinois ).'' Prepared by Illinois Department of Public Health under a Cooperative Agreement with the Agency for Toxic Substances and Disease Registry. (2004, April 14).〕 Eventually, it was convicted of water pollution offences spanning a decade, which contravened US federal law. The company's former site is now a Superfund site on the National Priorities List.〔(【引用サイトリンク】 publisher=EPA )〕 ==History== The company originated on June 9, 1969 as an Illinois corporation, Chemico Metals Corporation.〔Chemetco company literature (Prosecution exhibit 7.)
