Suncoke Energy, Inc.

A maker of metallurgical coke—the purified coal fuel that feeds blast furnaces making steel. SunCoke's heat-recovery ovens bake coal for about 48 hours and then capture the waste heat to generate steam and electricity for power plants. The name fuses its old parent company Sunoco (the Sun Oil Company) with "coke," and the business began in the 1960s when an engineer built three test ovens in Vansant, Virginia, to see if Virginia coal could yield quality coke.
