Surplus Military Propellants as Ingredients in Commercial Explosives

The use of military-type energetic materials in commercial explosive products is not a new concept. In the United States, the techniques for utilizing significant quantities of surplus military explosive materials by commercial explosive manufacturers dates back to the 1950’s. At times, explosive companies have found surplus military high explosives and propellant materials to be suitable ingredients for their commercial explosive products. The availability of these military-type energetic materials has varied over the past 50 years, as a function of the military’s strategic defense needs and the advances in modern weapon technology. For the most part, the commercial explosives industry has been able to implement methods for safely incorporating military-type high explosives and propellant materials, whenever these surplus materials become available. During the past 5-6 year period, a large amount of military-type energetic materials have once again become available for recycling into commercial explosives. This situation can be attributed to a number of factors, such as the political changes in Europe, the development of more sophisticated weapons systems, and the increased EPA pressures on the U.S. Department of Defense for disposing of surplus energetic materials. As in the past, U.S. commercial explosive manufacturers have made efforts to recycle these surplus materials into their explosive products. This paper describes some of the commercial explosive products that are currently on the U.S. market, which contain rocket and gun propellants as energetic ingredients. Some U.S. explosive companies, such as DYNO NOBEL, ORICA and Slurry Explosive Corporation, have been able to recycle significant quantities of surplus smokeless powder and composite propellants as energetic ingredients into their commercial Blasting Agents. The successes enjoyed by these companies have once again shown recycling into commercial explosive products to be an economically and environmentally sound method for disposing of surplus military-type energetic materials.
