Abstract
Containerized medical waste is treated by shredding, and then passing the shredded material, by means of a screw conveyor, through a direct steam impingement stage and a dehydration stage in which the material is brought into contact with a hot surface to vaporize moisture and thereafter passed through a low pressure chamber in which the vapor is drawn off.
