Eco Material Technologies and Bismarck, N.D.-based Rainbow Energy Center will invest in harvesting and beneficiation plants at the utility’s Coal Creek Station, transforming impounded bottom ash materials to construction-grade fly ash and gypsum. North Dakota’s first of their kind and Eco Material’s second such investments, the plants will have projected annual yields of a) 400,000 tons of supplementary cementitious materials over the next 25 years for North Dakota, Minnesota and Wisconsin concrete markets; and, b) up to 150,000 tons of calcium sulfite, or synthetic gypsum, for wallboard production. The harvesting and beneficiation project extends a partnership under which Eco Material markets upwards of 500,000 tons of fly ash per year from the facility’s present power generation.
“This project marks a key turning point in the SCM market for the region. We expect demand for high-quality, sustainable cementitious materials like fly ash and pozzolans to grow rapidly over the next 10 years,” says Eco Material CEO Grant Quasha. “This project is the culmination of a relationship between Eco Material and Coal Creek Station on fly ash beneficial use for over 30 years, and that partnership has only grown since Rainbow’s purchase of the facility.”
“Our vision for Coal Creek Station remains the same today as the day we developed the business plan for the facility. Our number one priority will always be to continue to operate it in the most efficient and environmentally sound way possible,” adds Rainbow President Stacy Tschider. “The expanded partnership with Eco Material Technologies enhances the execution of our vision by reducing carbon emissions and our environmental impact while continuing to provide valuable baseload energy to the market.”
