Abstract:

Munition production operations generate a large amount of waste material, which has historically been disposed of by open burning OB and open detonation OD. However, OBOD presents the potential for contamination of air, water, and soil. Increasingly stringent environmental regulations may force the interruption of munitions production if alternative waste disposal options such as controlled incineration, wet air oxidation, super critical water oxidation, and composting are not developed. This study evaluated the biodegradation of triple M3 lAlEl and double base NOSIH-AA2 propellants in compost, liquid culture, and soil slurries. No biodegradation of the production grade propellants was observed in compost or soil slurry incubations. In serum bottle incubation studies, some components of the propellants were biodegraded. The nitroglycerin component of both propellants was degraded in both the experimental and sterile control bottles in less than 1 week, suggesting an abiotic mechanism was responsible for its degradation. Nitroguanidine, a component of propellant M3lAlEl, was resistant to biodegradation. However, when an additional electron donor was added to the medium, 62 percent of the nitroguanidine was biodegraded under methanogenic conditions. The study concludes that biological treatment processes will have a limited role in disposing of production grade propellants.
