Abstract

We report on the potential for using dissolved ozone in water – ozonation – to oxidize trash and waste. An SBIR Phase II pilot scale ozonation system developed by TDA Research, Inc. was tested for use in oxidizing various mixtures of trash and wastes that included plastics, foodstuff, packaging, cloth, paper, fecal simulant, and pre-processed Heat Melt Compactor tiles. In addition to pure liquid phase ozonation, we also modified and tested the system for gas phase ozone oxidation in saturated water vapor with a heating element to promote smoldering. These tests were conducted as part of the NASA “Trash to Gas” project to identify candidate technologies for processing low value trash and waste into higher value product gasses.
