Ex-Situ Thermal Desorption of Hydrocarbon-Contaminated Soils in Arctic Conditions

More than 140 tonnes of soils contaminated with helicopter fuel, diesel, and heavy fuel oil were successfully remediated through Ex-Situ Thermal Desorption, achieving hydrocarbon reduction efficiencies exceeding 95% and demonstrating a fast, reliable remediation solution for remote Arctic locations.

SITE DESCRIPTION

       Treated Volume

  79 m³ of contaminated soil
