Alliant Energy Coal Ash Reclamation

(Alliant Energy.com - 2008) In 2007, Alliant Energy utility companies were able to beneficially use over 550,000 tons of coal combustion products (CCP), thereby diverting it from being placed in a landfill as a waste material. This includes fly ash, bottom ash, slag and other by-products generated from the direct combustion of coal.
