A method for removing contaminants from contaminated material such as contaminated soils and contaminated construction debris comprises the following steps: Separating the materials into a first fraction having particles of a size greater than 50 mm and a second fraction comprising remaining particles; breaking up the particles of the first fraction into particles of a size smaller than 50 mm; combining the particles of a size smaller than 50 mm and the second fraction to a combined fraction; drying the combined fraction at a temperature of between 100 DEG to 130 DEG C.; breaking up the combined fraction into particles of a size smaller than 2 mm; and subjecting the particles of a size smaller than 2 mm to a distillation process at a process temperature from between 300 DEG to 600 DEG C. Preferably, the distillation process is a vacuum distillation process with a process temperature of between 350 DEG to 450 DEG C.
