One was a pesticide contaminated soil with a low mass fraction of hazardous constituents compared to the soil. The other materials tested were with organic aqueous solutions being fed directly to the process. The table lists the different compounds based upon the University of Dayton s ranking systems that lists different organics and the relative difficulty to destroy. This provides some indication of the relative effectiveness of the process compared to other compounds for which the process has not yet been demonstrated. Compound 1 is the hardest to destroy.
Vitrification provides high volume reduction of wastes.
For some situations, the volume reduction achieved during waste processing is important. PermaVIT melting, even of soils, is profitable if the volumes are high. Typical values for some tested materials are shown graphically in Figure 6. The bar chart shows the volume percent of the final glass compared to the original volume. As indicated the final volume is nearly always less than the original waste.
