Abstract: The environmental impact of the disposal of spent, calciumbased sulfur sorbents (limestones and dolomites) and fuel-ash from fluidized-bed combustion and gasification of coal and residual oil has been investigated. Direct disposal and disposal after processing of the solids to reduce environmental impact or to provide a resource have been considered. Available data indicate that nonhazardous disposal of waste solids can be achieved. Research and development needs are assessed on the basis of data and process evaluations on the disposal of unprocessed and processed effluent solids from fluidized-bed combustion and gasification processes.
