IPL produces approximately 1.3 million tons of coal combustion products annually. The company is a leader in Indiana in its reuse program for fly ash, bottom ash and FGD scrubber material. Typically, IPL is able to beneficially reuse 35% of the ash produced and 85% of the gypsum produced. In 2013, approximately 150,000 tons of ash was used to manufacture concrete and cement, and for mine reclamation. Additionally, 450,000 tons of gypsum was used to manufacture wallboard and cement, and as an agricultural soil amendment.
In 2014 and 2015, IPL is moving forward with additional plans and research relating to the environmental benefits of using FGD gypsum, with expectations of expanding the market and benefiting the environment at the same time.
