  • Beneficial use of energy-containing wastes
    Patent number: 5612507
    Abstract: A process and composition for the beneficial utilization of waste materials which contain energetic materials are disclosed. Predetermined quantities of the waste material containing energetic materials are placed in admixture with commercial blasting agents causing the energetic materials to participate in the detonation process thereby utilizing energetic materials which would otherwise enter the waste stream. The waste material, in particulate form, that contains the energetic material is introduced into the blasting agent when the latter is in a relatively fluid state. The modified blasting agent is suitable for use in the normal manner such as in bulk or packaged form.
    Type: Grant
    Filed: December 12, 1994
