Gas powered thermal conductive heating of impacted soils 

for complete, rapid and cost effective remediation of organic contamination

In-situ and Ex-situ


How it Works




Technology Snapshot


Technically....Why Thermal Works:

  • Vapour pressure of organics increases
  • Viscosity of free phase contaminant decreases
  • Sorption coefficients of dissolved contaminants decreases
  • Diffusion rates increase
  • Narrow range in thermal conductivity between soil types
  • Solubility increases
  • Abiotic degradation increases
  • Pyrolysis can occur
  • Oxidation can occur

Contaminants Treated:

  • All VOCs and SVOCs
  • PAHs
  • Long chain Hydrocarbons
  • Tar
  • Mercury
  • Dioxins
  • Pesticides, Fertilizers and POPs
  • PCBs


When to Consider Gas Thermal Remediation (GTR)


  • For Rapid Schedules:  Real Estate / Brownfields Transactions
  • Anytime Thermal Treatment is Considered (ERH, ISTD, ex-situ)
  • When Guarantees Of Performance And/Or Schedule Are Required
  • Anytime Excavation & Off Site Disposal is Considered
  • For Source Zone Remediation
  • Former MGP Sites
  • PCB / POP Impacted Soils
  • Complex Lithologies
  • Where The Contaminant Can Be Used As A Fuel Source For Heat Generation (GTR+F)





  • Rapid treatment times:  weeks or months, not years
  • Fixed competitive pricing with remediation guarantee options
  • Scalable
  • No excavation/transport of soils off site
  • No soil movement:  no odour or dust
  • Advanced vapour treatment options
  • No power utility upgrades needed (subject to vapour treatment options)





GEO's combined resources in Europe and America:

  • Completed over 40 projects (in-situ and ex-situ)
  • 8 milliion tons of soil treated by thermal desorption
  • 5 million litres of VOCs extracted/treated from in-situ zones
  • Technical staff have over 2 decades of experience in thremal desoprtion and in-situ remediation
