Gradient Technology developed a technology to recover valuable explosive components from polyurethane based plastic bonded explosives. Gradient Technology will design, construct, and demonstrate a transportable process plant that can fluid jet wash out plastic bonded explosives from a munition or rocket casing. The polyurethane binder in the resulting slurry is decomposed allowing the recovery of the explosive particles for reuse. Monomer precursors can also be recovered from the decomposed polyurethane binder.
