Cofiring hazardous waste fuels in industrial processes. The business decision.

Abstract

Although energy-intensive industrial processes have the potential to incinerate hazardous wastes while effecting fuel cost savings, increased government regulation and heightened public interest require that the financial aspects of a hazardous waste fuel (HWF) program be considered fully. Apparent fuel savings are offset by the capital requirements for institutional factors such as permitting and public relations. This paper provides cost information for initiating and operating a HWF program, and outlines the steps required to perform a thorough financial analysis. Falling fuel prices lessen the appeal of HWF programs, and unless the facility is paid to accept the HWF, only very large users (more than 80 × 109 Btu/yr) of energy can consider them. The paper includes a figure from which the reader can estimate the return on investment for HWF programs over a range of program sizes (80 × 1200 × 109 Btu/yr).
