  • Content Description: If the US is to continue to effectively use its substantial coal reserves, new clean coal technologies must be developed to improve power production efficiency and reduce emissions from power plants. In order to gain information about wastes produced by advanced coal utilization processes, a research project is being conducted to characterize the geotechnical and geochemical properties of advanced coal process wastes. The University of North Dakota Energy and Environmental Research Center (EERC) analyzed 34 of these wastes for their bulk chemical and mineral compositions and for the disposal-related physical properties listed in a table. This paper discusses potentially useful waste management practices for eight bulk waste samples obtained from four different clean coal processes: gas reburning with sorbent injection (GRSI); pressurized fluidized-bed combustion (PFBC); SO{sub x}, NO{sub x}, RO{sub x}, BOX (SNRB); and coal reburning (CR). All four processes have been demonstrated at either full-scale or pilot-scale facilities in the US. Since the properties of advanced process wastes are different from conventional coal combustion wastes, an analysis was performed to identify any potential problems that could occur when standard, off-the-shelf waste management technologies are used for handling and disposal of advanced process wastes. When potential problems were identified, possible alternative technologies were evaluated.
