Coal Ash Containment
- Coal Ash Containment×
The combustion of coal to generate energy means the creation of coal ash (fly ash) the byproduct of combustion; an estimate of coal ash generation in calendar 2007 is 131 million tons. Some of this material can be recycled into other products such as gypsum (wallboard stock) or used to enhance/extend concrete manufacture. But the majority of the coal ash must be stored. How to safely and effectively store this material is the purpose of this paper.
