ABSTRACT:
Waste energetic compositions such as solid rocket propellant are treated to reclaim valuable aluminum particles and oxidizer in a form in which they can be reused, and to incinerate the remaining solids in a totally environmentally sound manner. An initial percentage (40-50% by weight) of the oxidizer is extracted during hydromining when the propellant is removed from the casing of a rocket motor. Additional oxidizer (35-45% by weight) is extracted from the propellant during subsequent underwater high speed maceration operations. The residual material containing mostly aluminum and binder matrix is thermally destroyed in a closed incinerator and the aluminum recovered as very high purity aluminum oxide.
