OSTI ID:6483847

Included in this analysis are an evaluation of conventional and non-conventional recycling processes, their technical and economic feasibility, and requirements for further development within the United States. This study considered a number of processes proposed by both domestic and international organizations. All of the processes studied produce a product for potential reuse in the steel industry. Estimates were made of the processing energy involved in treating the dusts and sludges, the energy associated with raw materials used in the processing of the dusts and sludges, the energy associated with transportation, and the energy required to convert the recycled material to molten pig iron. The summation of these energies was compared to a base case for energy consumption in the production of pig iron in a blast furnace from iron ore, coke, and limestone. By this methodology, a comparison was made of the potential energy savings of processing steel mill dusts and sludges and utilizing them to replace iron ore units.
