The microemulsion process for material synthesis and other applications has sometimes been termed an emergent technology , and therefore, new developments are also taking place to increase the suitability of the process. One such important development that has taken place in microemulsion-mediated particle synthesis is the use of water-supercritical CO2 systems [225-227, 229, 425,445]. Though this system is also valid for macro- and miniemulsions, reports of particle synthesis (metals, sulfides, halides, as above) are so far essentially microemulsion-based. As the system is environment-friendly and follows some of the important requirements of green chemistry [452], this process is expected to be further matured into a technology for nanoparticle synthesis. The present scale of operation, however, is apparently very small. 

Figure ES-2 is a block diagram of the Eco Logic technology process. The primary treatment destroys the agent and the energetic materials by hydrolysis with caustic or water. Flowever, the hydrolysis products (hydrolysates) must be further treated prior to final disposal. For this secondary step, Eco Logic proposes to use a transpiring-wall supercritical water oxidation (SCWO) reactor design. The following major operations are included ...
