Large-Scale Thermal Remediation of Hydrocarbon and Explosive-Impacted Soils at a Former Industrial Site, France

More than 12,000 m³ (21,000 tonnes) of soils contaminated with hydrocarbons, BTEX, PAHs, and residual explosive compounds were successfully remediated through multiple Ex-Situ Thermal Desorption batches, demonstrating an effective solution for large-scale treatment of complex contamination across a former industrial site.
