DEMILITARIZATION AND WASTE DISPOSAL
Waste Disposal Technology
UNMATCHED CAPABILITY
The General Dynamics Ordnance and Tactical Systems Munition Services facility has been designed, sited and built to handle Classes 1.1 to 1.6 explosive materials and items. Our advanced explosive waste disposal technology features a unique rotary kiln, car bottom furnace, air pollution control system along with a computer control system for controlled waste disposal.
State-of-the-Industry
Incinerators
The heart of General Dynamics Ordnance and Tactical Systems Munitions Services explosive waste disposal services is our two RCRA Part B permitted and MACT compliant incinerators.
Rotary Kiln Incinerator (RKI)
Our RKI is the only commercial hazardous waste incinerator in the U.S. that is specifically designed for the incineration of explosive materials and devices.
Car Bottom Furnace
The Car Bottom Furnace incinerator is a batch furnace for flashing or burning explosives contaminated materials which generally generated from explosive manufacturing operations.
Waste Treatment Methods
Thermal
Treatment
The General Dynamics Ordnance and Tactical Systems Munition Services has several permitted thermal treatment units at the end of automated disassembly lines demilitarizing ICM and MLRS grenades, and MLRS rocket motors. In these units, the explosives or propellants are ignited and allowed to burn within the units. Exhaust gases are pulled from the units and cleaned in air pollution control systems to meet RCRA and Title V MACT emission standards. These specialized units free up incineration capacity since these materials do not need to be processed through the Rotary Kiln Incinerator (RKI), while meeting the same emissions standards of the RKI.
Preprocessing
Methods
Many explosive materials and devices cannot be directly fed to our Rotary Kiln Incinerator (RKI). So in order to make them “incinerable”, GD-OTS MS has developed several preprocessing methods and equipment, to include:
- Repackaging of bulk materials into smaller quantities
- Disassembly of items using various pieces of automated disassembly equipment
- Delinking of linked ammunition
- Sawing of items to reduce the quantity of or expose the explosive filler
- Shearing of solid propellants
Air Pollution
Control and Regulation
Like all hazardous waste incinerators in the U.S., General Dynamics Ordnance and Tactical Systems Munitions Services permitted hazardous waste incinerators are highly controlled and regulated such that the emissions from disposal of explosive wastes are cleaned of any harmful chemicals, particulates, and heavy metals. This is accomplished by a state-of-the-industry air pollution control system (APCS) which cleans all of the emissions from our incinerators such that they meet the MACT standards for hazardous waste incinerators.

Our APCS consists of a secondary combustor which raises the exhaust gas temperature coming from the two incinerators to a minimum of 1800 degrees F, with a residence time of at least 4 seconds at that temperature. Following the secondary combustor, the exhaust gases enter a spray dryer where the gases are rapidly quenched to 375 degrees F. Soda ash (sodium carbonate) can be added to the quench water as necessary to neutralize acid gases. From the spray dryer, the exhaust gases, enter baghouses which filter the particulate from the gas stream. Cleaned exhaust gases then exit the system through our 215 ft high stack. As the gases exit the stack, they are continually monitored by our continuous emissions monitoring system to ensure that all of the APCS equipment upstream are functioning properly.
