The present invention concerns a method for processing and detoxification of a material, especially a thermoplastic material, and for removal of contaminants or impurities from this material, wherein the material is heated under vacuum in at least one receiving tank, mixed and possibly comminuted, and wherein a rinsing medium is introduced into the receiving tank beneath the material level, conducted through at least a partial region of the material, and the rinsing medium enriched or saturated with contaminants is brought out from the receiving tank once more. According to the invention, the quantity of rinsing medium introduced into the receiving tank is less than 0.1 liter per hour per kilogram of material or material throughput per hour, while at the same time the vacuum in the receiving tank is kept constantly below 100 mbar.
