Radford and McAlester Army Ammunition Plants must dispose of significant amounts of scrap or off-spec propellant each year. Traditionally, they used clay-lined steel pans for the burning operations. Bare metal pans would warp from the heat of the burning propellant and clay-lined pans lasted longer but the clay had to be disposed of several times each year as hazardous waste. Once the Army redesigned the pans, Corrpro assisted by arranging for the manufacture of ceramic refractory lined pans which resulted in a hazardous waste reduction of over 500,000 pounds annually and saved $400,000 in hazardous waste disposal costs.
