Following the International Treaty held in London and Oslo in 1972 and its amendment in Paris in 1992 on banning the dumping of hazardous and toxic waste at sea; large stockpiles of unwanted munition are now awaiting disposal. Public awareness; environmental concern and legislation are preventing the disposal of this explosive waste by landfill; detonation and open pit burning. One solution to this dilemma is to recover the waste from the containers and recycle the waste in an environmentally sensitive manner. In this investigation; a study was conducted to explore the possibility of recovering RDX from a PBX using a supercritical fluid. An environmentally friendly method for the resource; reuse and recycling was also developed. The results showed that RDX could be extracted from PBX using supercritical carbon dioxide and that the recovery is enhanced by using co-solvents. Two methods have been proposed (SWAT and DARE) which lead to an increase in RDX recovery yield and shorten the extraction time.
