Below are only several of the successful Canadian and International Projects for which the TPS technology has been used

Location: Japan Duration: 2002-Ongoing Contaminant: PCB, PAH, Cyanide Impacted Soil

After successful operations in Australia and field testing in Japan, using the TPS Pilot Scale Unit, a TPS unit was purchased by a major Japanese conglomerate for exclusive use in Japan. After several months of refitting to meet specific Japanese environmental and operational requirements the TPS unit was placed into successful commercial operation.

Location: Sydney, Australia Duration: 1999 Contaminant: PCDD/PCDF and Organochlorine Compounds

In 1999 Australian Defence Industries (ADI) was contracted by the Olympic Coordination Authority (OCA) to remediate a site adjacent to the 2000 Games Olympic Village contaminated with dioxins/furans and chlorobenzenes. This site was located on an abandoned pesticides production facility at Homebush Bay in Sydney, Australia. In keeping with the regulatory goals of the Australian environmental authority and the stated principles of the OCA a comprehensive, non-incineration, on-site solution was demanded.

ADI initiated a comprehensive and integrated strategy to both remediate the site in question and destroy, on-site, the collected organochlorine contaminants. It contracted the TPS, indirect thermal desorption technology after an exhaustive international seach, which effectively extracted the contaminants from the soil while ADIs ADOX/BCD technology destroyed the produced contaminant concentrate using a proprietary chemical dechlorination process. Both technologies are highly efficient and do not utilize incineration therefore protecting against the hazards associated with high temperature incineration (PIC production and toxic emissions) and off-site transport.

The project success was publicly recognized by the Australian branch of Greenpeace and promoted as the preferred method for management of persistent organic pollutants worldwide.

Location: Quebec Duration: 1997-98 Contaminant: PCB-Aroclor 1260, PAH, PCP contaminated soils, sludges, sediments

In 1997-98 the TPS was established in Sherbrooke, Quebec for the treatment of PCB and PAH contaminated soils, sludges and sediments received from a number of clients across Canada. One of the series of projects conducted was the treatment of PCB contaminated soil with a very high percentage of highly plastic clay. This soil averaged 69% clay with 0-80um particle size distribution and an average 23% moisture content. The high clay content makes any treatment process very difficult due to the high surface area and entrapment of hydrocarbons in the pore spaces of the clay particles. The TPS technology successfully treated this material to a PCB remediation criteria of < 1mg/kg.

In addition to this challenging project, the TPS completed treatment and decontamination of a volume of PCB contaminated soil generated by a Canadian Provincial crown corporation allowing it to complete a major divestiture of assets. The TPS also treated an additional volume of PCB contaminated soil on behalf of a major Canadian financial institution allowing it to complete a significant real estate transaction. During this mobilization the TPS also completed a full scale treatability test of PAH and PCB contaminated sludge and sediment from the Sydney Tar Ponds site. The TPS is the only technology to have undertaken such a study for what is considered the most contaminated site in Canada, containing over 700, 000 mT of PCB and PAH contaminated material.

Location: Villano, Ecuador Duration: 2000-2001/2002-2003 Contaminant: Synthetic Base Drill Cuttings

The TPS was contracted to provide thermal treatment services for SBM contaminated drill mud and cuttings and base oil recovery. The drill site located at Block 10 near Villano, Ecuador was, for environmental reasons, a helicopter site. All equipment, supply and personnel was airlifted in and out. The TPS equipment was transported in 8, 000kg lifts into a site located in one of the most biologically diverse regions of the planet. In total the TPS successfully treated over 20, 000mT of contaminated cuttings with an average 34% TPH producing a benign solid with
