  • Patent number: 5252290
    Abstract: A process and apparatus are provided to treat and dispose of medical waste materials to thereby enhance public heath and social hygiene. The medical waste material is sealed in a suitable nonflammable and long infrared radiation pervious container. The container with the waste material therein is subject to long infrared radiation for a sufficient period of time to heat the waste material to sterilizing temperature levels. The container and the sterilized waste materials are then crushed to reduce the same to granular form to facilitate convenient and safe ultimate disposal. Thus, medical waste materials can be treated and rendered harmless immediately and safely at the place where they are created. Such on-site treatment minimizes the cost involved in ultimate disposal and the potential for human contact with dangerous pathogenic waste.
