Producer of calcined petroleum coke (CPC). The company uses anode grade CPC, which is the principal raw material used in the production of carbon anodes for use in aluminum smelting. Its carbon anodes are used by primary aluminum smelters as a key component in aluminum smelting pot lines, which act as conductors of electricity and as a source of carbon in the electrolytic cell that reduces alumina into aluminum metal. It also sells industrial grade CPC for use in the production of titanium dioxide, as a carbon additive in the manufacture of steel and foundry products; and for use in other specialty materials and chemicals markets. It sells its CPC to end users through its direct sales staff and exclusive sales representatives. As of June 2008, the company operates as a calcining division of Oxbow.
