Electric utilities and other commercial/industrial companies that burn coal as a heat source are responding to increasing competitive pressures by pursuing all possible ways to reduce fuel costs. One cost saving measure that is gaining popularity is supplementing traditional coal supplies with waste byproducts from other industries. Such byproducts include tires, sawdust, wood chips, various types of sludge and food wastes. Although many of these byproducts are available at little or no cost, the coal users are limited in their abilities to use the byproducts because their facilities were designed to handle coal that has different chemical and physical properties than the byproducts. However, waste byproducts can be combined with coal and pelletized into a coal-like fuel to provide a fuel cost savings without the capital expense for retrofitting existing coal handling and combustion systems and recognize reductions in their air emissions . A Westvaco Corporation facility in Tyrone, Pennsylvania is currently utilizing such a fuel, marketed as E-Fuel{trademark}, as their complete fuel feedstock. This paper reviews research and current technologies for producing coal-like fuel from waste byproducts and coal or coal fines. It discusses the various waste byproducts and binders that were investigated. It concentrates on the combination of paper sludge (byproduct of the paper industry), low-density polyethylene plastic waste, and coal that represent the main raw materials for E-Fuel{trademark}. The paper will present and discuss the economics associated with the existing installation at Tyrone, PA with respect to their stoker coal-fired boiler and their overall operation and it will discuss the realized reduction of SO{sub 2}, NO{sub x} and particulate emissions at this facility. This paper will demonstrate that pelletizing technologies, such as E-Fuel{trademark}, provides an economical fuel alternative to coal.
