Army Ammunition Plants AAPs dispose of large quantities of solid waste by incineration, open-air burning, and landfill. There is at present no attempt at energy recovery. The present study was conducted to determine the feasibility of adapting pyrolysis technology for energy recovery from these solid wastes. Eight AAPs were surveyed to identify the types and amounts of solid waste generated. Candidate systems were evaluated to determine their suitability for this application. Safety considerations indicate that propellants, explosives and pyrotechnics PEP and PEP-contaminated waste with proper precautions could be handled safely by pyrolysis processes, but further work is needed to determine applicable size reduction techniques. It was determined that a 45.4 MGd 50 TPD plant would be sufficient to handle the largest quantity of waste generated at any AAP. Capital cost was estimated at 4.1 million and annual cost at 623,100. Based on these costs it was concluded that pyrolysis is not economically feasible at this time even under mobilization conditions.
