FRANCIS W. HOLM Science Applications International Corporation 7102 Meadow Lane, Chevy Chase, MD 20815 The North Atlantic Treaty Organization (NATO) sponsored an Advanced Research Workshop (ARW) in Warsaw, Poland on April 24-25, 1995, to collect and study information on alternative and supplemental demilitarization technologies. The conference included experienced scientists and engineers, who delivered presentations and provided written reports oftheir findings. Countries describing their technologies included: Poland (pre-processing, thermal oxidation, and instrumentation), Russia (molten salt oxidation, plasma, catalytic oxidation, supertoxicants, molten metal, fluid bed reactions, and hydrogenation), Germany (supercritical water oxidation and detoxification), the United Kingdom (electrochemical oxidation), the United States (wet air oxidation, detoxification and biodegradation), and the Czech Republic (biodegradation). The technologies identified for assessment at the workshop are alternatives to incineration technology for chemical warfare agent destruction. Treatment of metal parts and explosive or energetic material were considered as a secondary issue. The treatment of dunnage and problems associated with decontamination, while recognized as an element of demilitarization, received only limited discussion. The alternative technologies are grouped into three categories based on process bulk operating temperature: low (O-200°C), medium (200-600°C), and high (600-3,500°C). Reaction types considered include hydrolysis, oxidation, electrochemical, hydrogenation, and pyrolysis. These categories represent a broad spectrum of processes, some of which have been studied only in the laboratory and some of which are in commercial use for destruction of hazardous and toxic wastes. Some technologies have been developed and used for specific commercial applications.

FRANCIS W. HOLM 7102 Meadow Lane, Chevy Chase, MD 20815 The North Atlantic Treaty Organization (NATO) sponsored an Advanced Research Workshop (ARW) in Prague, Czech Republic, on 1-2 July 1996, to collect and study information on mobile alternative and supplemental demilitarization technologies and to report these fmdings. The mobile, or transportable, technologies identified for assessment at the workshop are alternatives to incineration technology for destruction of munitions, chemical warfare agent, and associated materials and debris. Although the discussion focused on the treatment of metal parts and explosive or energetic material, requirements for decontamination of other materials were discussed. The mobile alternative technologies are grouped into three categories based on process bulk operating temperature: low (0-200 C), medium (200-600 C), and high (600- 3,500 C). Reaction types considered include hydrolysis, biodegradation, electrochemical oxidation, gas-phase high-temperature reduction, stearn reforming, gasification, sulfur reactions, solvated electron chemistry, sodium reactions, supercritical water oxidation, wet air oxidation, and plasma torch technology. These categories represent a broad spectrum of processes, some of which have been studied only in the laboratory and some of which are in commercial use for destruction of hazardous and toxic wastes. Some technologies have been developed and used for specific commercial applications; however, in all cases, research, development, test, and evaluation (RDT &E) is necessary to assure that each technology application is effective for destroying chemical warfare materiel.

In 1994 the National Research Council published Recommendations for the Disposal of Chemical Agents and Munitions, which assessed the status of various alternative destruction technologies in comparison to the Army's baseline incineration system. The volume's main finding was that no alternative technology was preferable to incineration but that work should continue on the neutralization technologies under Army consideration. In light of the fact that alternative technologies have evolved since the 1994 study, this new volume evaluates five Army-chosen alternatives to the baseline incineration system for the disposal of the bulk nerve and mustard agent stored in ton containers at Army sites located in Newport, Indiana, and Aberdeen, Maryland, respectively. The committee assessed each technology by conducting site visits to the locations of the technology proponent companies and by meeting with state regulators and citizens of the affected areas. This volume makes recommendations to the Army on which, if any, of the five technologies has reached a level of maturity appropriate for consideration for pilot-scale testing at the two affected sites.

The U.S. military has a stockpile of approximately 400,000 tons of excess, obsolete, or unserviceable munitions. About 60,000 tons are added to the stockpile each year. Munitions include projectiles, bombs, rockets, landmines, and missiles. Open burning/open detonation (OB/OD) of these munitions has been a common disposal practice for decades, although it has decreased significantly since 2011. OB/OD is relatively quick, procedurally straightforward, and inexpensive. However, the downside of OB and OD is that they release contaminants from the operation directly into the environment. Over time, a number of technology alternatives to OB/OD have become available and more are in research and development. Alternative technologies generally involve some type of contained destruction of the energetic materials, including contained burning or contained detonation as well as contained methods that forego combustion or detonation. Alternatives for the Demilitarization of Conventional Munitions reviews the current conventional munitions demilitarization stockpile and analyzes existing and emerging disposal, treatment, and reuse technologies. This report identifies and evaluates any barriers to full-scale deployment of alternatives to OB/OD or non-closed loop incineration/combustion, and provides recommendations to overcome such barriers.

In Advanced Physiochemical Treatment Technologies, leading pollution control educators and practicing professionals describe how various combinations of different cutting-edge process systems can be arranged to solve air, noise, and thermal pollution problems. Each chapter discusses in detail the three basic forms in which pollutants and waste are manifested: gas, solid, and liquid. There is an extensive collection of design examples and case histories.

FRANCIS W. HOLM 30 Agua Sarca Road, Placitas, New Mexico 1. Overview The North Atlantic Treaty Organization (NATO) sponsored an Advanced Research in Prague, Czech Republic, on October 13-15, 1997, to collect and Workshop (ARW) study information on effluents from alternative demilitarization technologies and to report on these fmdings. The effluents, orprocess residues, identified for assessment at the workshop are generated by systems that have been proposed as alternatives to incineration technology for destruction of munitions, chemical warfare agent, and associated materials and debris. The alternative technologies analyzed are grouped into three categories based on process bulk operating temperature: low (0-200 C), medium (200-600 C), and high (600-3,500 C). Reaction types considered include hydrolysis, biodegradation, electrochemical oxidation, gas-phase high-temperature reduction, steam reforming, gasification, sulfur reactions, solvated electron chemistry, sodium reactions, supercritical water oxidation, wet air oxidation, and plasma torch technology. These ofprocesses, some of which have been studied categories represent a broad spectrum only in the laboratory and some of which are in commercial use for destruction of hazardous and toxic wastes. Some technologies have been developed and used for specific commercial applications; however, in all cases, research, development, test, and evaluation (RDT&E) is necessary to assure that each technology application is effective for destroying chemical warfare materiel. Table 1 contains a list of more than 40 technologies from a recent report for the U.S. Army [1]. Many ofthe technologies in Table 1 are based on similar principles.
