Nebraska Ash was formed in 1976 for the purpose of handling coal combustion products at coal fired electric generating stations. Nebraska Ash provides services such as marketing, storage and disposal for Omaha Public Power District, the city of Fremont and Nebraska Public Power District through its subsidiary Plains Pozzolanic.
During the combustion of coal, the residue that remains forms two products. The primary product being fly ash, a finely divided material, and the other being bottom ash, a coarser material. NEBCO engineers pioneered the use of fly ash in Nebraska as a raw material for Portland cement concrete production and as a soil stabilization material. Bottom ash is utilized as a fill material and road aggregate. Formerly, all coal combustion products produced in Nebraska were disposed of in landfills. Nebraska Ash has operations in Omaha, Nebraska City and Fremont.
