Abstract: An apparatus and method for rendering infectious and medical waste safe through heating and the disposal of said waste includes a body portion with a chamber to receive a container of medical waste. The chamber is connected with a filter for biological materials which escape from the waste container during heating. The contaminants are directed toward the filter by flowing out gas from the container in a predetermined direction as the waste container is heated to a temperature of preferably not less than 350.degree. F. and preferably not more than 385.degree. F. to render the waste biologically safe and unreusable.
