Abstract:

A common method of disposing of waste materials resulting from the production of illuminating flares is to burn them in a burning pit. This adds pollutants in the form of smoke and toxic or noxious fumes. To eliminate this source of pollution, a relatively facile scheme for isolating and reclaiming the magnesium and for the disposal of the sodium nitrate and binder residues from waste flare compositions has been developed. This scheme involves washing the flare compositions with water, and in some instances with acetone or other solvents, to remove sodium nitrate and most of the binder material. The remaining magnesium is dried and prepared for sale as scrap or for use in the production of new flares. Luminous intensity data, collected on prototype flares utilizing the reclaimed magnesium, suggest that reuse of the unadulterated material in illuminating composition production may not be feasible. Sodium nitrate, aqueous solution, is being evaluated for its nutrient value as a fertilizer and the intractable, infrangible binder is sent to land-fill. Author
