Coal combustion by-products (CCBs) are generated from the combustion of coal for energy production. Approximately 82 million tons of CCBs are produced each year by electric utilities. There are several common types of CCBs produced by coal combustion--fly ash, bottom ash, boiler slag, flue gas desulfurization material (FGD) and fluidized bed combustion byproducts (FBC). Some CCBs such as fly ash, have pozzolanic properties and may have cementitious properties, both of which are advantageous for engineering, construction and waste remediation applications. The American Society for Testing Materials (ASTM) in ASTM C-618 has created two classifications of useful and quality coal ash, Class F ash and Class C ash. Each class of coal ash has different pozzolanic and cementitious characteristics. Coal ash can be utilized in many manufacturing, mining, agricultural, engineering, construction and waste remediation applications. These potential applications may provide a new revenue source for utilities. The profitability of these applications can, however, be limited by applicable state regulations. Prior to initiating any reuse application, a utility should ensure regulatory approval of the proposed use. Approval may be apparent from a review of state law and regulations. Often times, further regulatory analysis and consultations may be necessary.
