  1. American Coal Ash Association, Alexandria, VA (United States)

The American Coal Ash Association, Inc., (ACAA) has represented the coal combustion byproduct (CCB) industry in the US since 1968. ACAA`s mission is to advance the management and use of CCBs in ways that are technically sound, commercially competitive and environmentally safe. ACAA conducts an annual survey of coal-burning electric utilities in the US to determine the quantities of CCBs that are produced and used. In 1994 approximately 80.8 million metric tons (89.0 million short tons) of CCBs were produced in the US in the form of fly ash, bottom ash, boiler slag and flue gas desulfurization (FGD) material. About 25% of the combined production of these CCBs was used, while the remainder was disposed. Quantities for CCB production and use in the US for calendar-year 1994 are summarized. In 1994 fly ash production alone amounted to 49.7 million metric tons (54.8 million short tons), and of that amount approximately 24%, some 11.7 million metric tons (12.9 million short tons), was used. The major applications for fly ash were: cement and concrete products (57.0%); structural fill (9.4%); road base (5.5%); flowable fill (5.0%); waste solidification and stabilization (1.9%); mineral filler applications (1.0%); mining applications (0.7%); and various other applications (19.5%). This information is shown.
