ABSTRACT:
An improved non-pyrolytic disposal process for nitrocellulose-based explosives and rocket propellants is disclosed. Explosive and propellant particles are digested by contact of the particles with an aqueous solution containing from about 5 to 20% by weight caustic (NaOH) maintained at a temperature of about 50.degree. C. to 100.degree. C. and under conditions of agitation until digestion is essentially complete. The resulting by product contains a mixture of depleted caustic and a water soluble sludge which can be disposed of or further processed. The process minimizes environmental concerns brought about by the open burning of high energy materials.
