The plant for making Coalite at Bolsover, Derbyshire, UK. Coalite was a 'smokeless' derivatve of coal and very popular as a domestic fuel from the 1920s to the 1990s but the plant was eventually closed because of general environmental issues and also because the Seveso tragedy awakened public concern about dioxins, which are emitted by the burning of coalite. Photographed in 1991.
