Limestone Resource Information Saves Money

On November 16, 2011, Zak Lasemi presented a talk titled, "Mapping High-Calcium Limestone Resources near Illinois Coal-Fired Power Plants" at the Illinois Clean Coal Institute's Program Committee meeting in Fairview Heights, Illinois. The committee included professionals with diverse interest and experience in coal, coal applications, and clean energy. After the presentation, Mark Bryant, Manager of Emission Control Commodities for Ameren, said that Lasemi's maps and data had been used to help identify deposits and quarries of this special limestone for use in his company's power plant scrubbers. The work has saved the company millions of dollars because the identified high-calcium limestone deposits were closer to the plants, which resulted in substantial savings in shipping costs.
