SunCoke produces metallurgical coke used to manufacture steel. The company currently operates plants in Virginia, Illinois, Indiana and Ohio, and is currently building a second, high-capacity facility in the Buckeye State. That plant, in Middleton, is slated to produce 550,000 tons of coke while at max capacity.
Coke is formed by super heating coal to bond carbon and ash. The process burns off contaminates like water and coal tar to create an energy-dense fuel. Byproducts of the process are typically used to generate electricity, as in the case with the Middleton plant.
Henderson, a long-time GM man, held the company's reins for a short time starting in 2009, but was replaced with Ed Whitacre amidst concerns that the company's turnaround wasn't moving fast enough.
