The Cryogenic ZAWCAD, developed by scientists at the DOE's Idaho National Engineering and Environmental Laboratory, Idaho Falls, and ZawTech International Inc., Roswell, Ga., combines cutting and cleaning technologies into one system and adds one enormous advantage--zero-added waste processing.
Water-jet or chemical treatments leave contaminated by-products to clean up, but the Cryogenic ZAWCAD gases evaporate, flow through a particle filter, and return harmlessly to the atmosphere.
Cryogenic ZAWCAD can also partially remove paint while leaving primer, so that the material is ready for another topcoat without intermediate polishing.
