Abstract: A method and apparatus for the treatment of contaminated medical waste, including solid and non-solid, potentially infectious materials, permits the collection of such medical waste at the point and at the time of its generation in a solid container, which is subsequently transported for pulverization, disinfection and safe disposal. A separate portable processing chamber, with an integral means to treat medical waste, is used at locations remote from its power unit for the collection of medical waste and then moved to the location of the power unit to drive the waste-treatment means within the chamber.
