Abstract
A method for destroying pyrotechnic materials including providing an apparatus having an inlet and an outlet and configured to mechanically destroy pyrotechnic materials and discharge pyrotechnic debris through the outlet, feeding water and pyrotechnic materials to the inlet of the apparatus so that the apparatus mechanically destroys the pyrotechnic materials and discharges pyrotechnic debris and water through the outlet, introducing the discharged pyrotechnic debris and water to a reservoir of water so that water-soluble components of the pyrotechnic debris dissolve into the water of the reservoir, light-density water-insoluble components float to the top of the reservoir and high-density water-insoluble components settle at bottom of the reservoir, and filtering the reservoir of water to separate water from the water-insoluble components.
