On 25 August 2010, AK Steel held a bricklaying event for a new SunCoke Energy Inc. plant in Middletown, Ohio, US. The event marked the initial construction phase of SunCoke’s USD 360 million plant located adjacent to AK Steel’s Middletown Works. Once completed, the environmentally friendly, heat-recovery coke battery will be capable of supplying AK Steel with about 550,000tns of metallurgical coke annually. In addition, the new plant will recover the waste heat from the coking process to generate approximately 50MW of electrical power each year, or about 25% of Middletown Works’ electricity requirement.
