Abstract
A method of decontamination for decontaminating plastics in solid particulate form includes the steps of: loading the plastics into a tank; introducing a liquid into the tank so that the liquid is in contact with the plastics; hitting the plastics in the tank and the liquid in contact with the plastics with ultrasonic waves. A decontamination apparatus actuates the decontaminating method and a plant includes the decontamination apparatus.
