Arabian Cement Company (ACC), the leading cement producer in Egypt, has expanded its use of coal and refused derived fuel (RDF) as a substitute for natural gas as an energy source for its production plant. With an investment of EGP 200 million, ACC’s latest coal mill, and its second in Egypt, helps the factory to operate using 14% alternative fuel material and about 86% coal. Since 2015, when ACC first implemented this groundbreaking approach to alternative fuel consumption in Egypt, the company has given away 100% of the amount of natural gas required to operate its plant, equating to 378 million m 3 of natural gas a year saved by the alternative fuel system.
