POLYSILICATE TECHNOLOGY – STATIONARY AND MOBILE SYSTEMS Dr. Trezek was instrumental in developing a cost-effective polysilicate technology which allowed the transformation of metals, e.g., lead, cadmium, zinc, chromium, arsenic, nickel, etc., from typically metal oxides into metal silicates, which then became part of a cementitious matrix. Thus, by altering the nature of the metal, the treated material was rendered essentially non-leachable when subjected to various extraction tests, such as the California Wet Test (CAM), and later the TCLP Test. This technology was the first accepted by the State of California Toxics Division for metal remediation. It was successfully applied to a host of materials; including auto-shredder residue, municipal solid waste, bottom and fly ash, sludges, filter cakes, mining wastes, etc. The process was later commercialized by Greenfield Environmental and used for soil remediation. A transportable treatment unit (TTU) was developed to allow metal-contaminated soils to be processed at 100 ton per hour rates. The nature of these treated materials was such that they could remain, that is, be backfilled on-site. Large scale remediation projects were completed at the Port of Los Angeles, Boeing Aircraft and numerous steel and scrap processing facilities.
