GOVERNMENT - THERMAL REMEDIATION
Thermal-Desorption-Direct

Thermal remediation of contaminated soils involves the removal of the contaminant(s) from the soil matrix using Toxfree's patented Thermal Desorption or Thermal Destruction technologies with all soil remediated to reuse criteria. The extracted contaminants undergo further treatment and/or destruction to remove all hazardous properties ensuring there are no ongoing liabilities for our clients.

Indirect Thermal Desorption (ITD)

ITD involves the the indirect application of heat to volatilise organic contaminants from the solid or soil matrix with the off-gas being condensed for subsequent recovery or destruction. This type of technology is generally applied when the contaminant has some economic value or when a high level of contamination is present (typically > 3% Total Organic Carbon) or where the contaminant is considered a Persistent Organic Pollutant or Scheduled Compound requiring further treatment for its safe disposal. Condensate recovered from the ITD process requiring destruction such as Polychlorinated Biphenyls (PCB's) and Organo-Chlorine Pesticides (OCP) are treated using Toxfree Plascon technology.

Direct Thermal Desorption (DTD)
 Thermal-Desorption-Indirect

DTD involves the direct thermal desorption of contaminants from a soil matrix and is largely focused at persistent organic pollutants that have little or no recovery value [e.g. polychlorinated biphenyl's (PCB's), polyaromatic hydrocarbons (PAH's), chlorinated solvents etc]. This type of technology is generally applied when a low level of contamination is present (typically < 3% Total Organic Carbon). Toxfree utilises a US manufactured state of the art 3 tonne per hour DTD unit.
