Power plant fly ash—disposal and utilization

Power plant fly ash generation rates, ash disposal methods and concerns, and opportunities for utilization are discussed. The US National Energy Plan of 1978 calls for a doubling of coal consumption by 1985 and a tripling by 1990. The environmental impact that will result from the disposal of the increased amounts of ash that will be produced is only now being realized. Current and proposed disposal methods and processes for resource recovery from the ash are discussed and compared to established practices in the United Kingdom. 5 figures, 2 tables.
