NOVELTY - Waste processing apparatus includes an waste input container having input and output openings, input door for output opening, a shredder mounted operative to shred waste, processing chamber where shredded waste drops, ozone gas source operative to direct ozone gas into the processing chamber, ozone indicator operative to indicate a concentration of ozone gas inside the chamber, and chamber exhaust to exhaust atmosphere from the chamber.    USE - For processing or treating waste (claimed), e.g. biomedical waste (i.e. blood, blood products, or tissues resected during surgery).    ADVANTAGE - The inventive apparatus is simple, easy to install, inexpensive to operate, and allows for automated and continuous treatment of the waste. The waste treated by the apparatus is free from pathogens, safe to dispose in, e.g. municipal landfills. The apparatus can be installed in hospital so that all waste from the hospital can be processed.    DETAILED DESCRIPTION - Waste processing apparatus (150) comprises:    (A) waste input container having an input opening in a top and an output opening in a bottom;    (B) input door (103) operative to close and seal the input opening;    (C) output door operative to close and seal the output opening;    (D) shredder mounted under the output opening and operative to shred waste to a desired maximum size;    (E) processing chamber located under the shredder so that when the output door is open, waste deposited in the waste input container passes through the output opening and through the shredder and shredded waste drops into the processing chamber;    (F) sealable discharge opening in the processing chamber;    (G) ozone gas source connected to the processing chamber and operative to direct ozone gas into the processing chamber;    (H) ozone indicator operative to indicate a concentration of ozone gas present in an atmosphere inside the processing chamber;    (I) chamber exhaust operative to exhaust the atmosphere from the processing chamber; and    (J) hopper exhaust operative to exhaust the atmosphere from the waste input container.    An INDEPENDENT CLAIM is also included for a method for processing biomedical waste comprising providing the shredder above the sealed processing chamber. A selected concentration of ozone is maintained in an ozone rich atmosphere inside the processing chamber during shredding at a level sufficient to sterilize the biomedical waste. Waste is fed into the shredder, which is then operated to shred the waste to a desired maximum size. Shredded waste is allowed to fall through the ozone rich atmosphere inside the processing chamber and the waste is kept in the processing chamber for a length of time to sterilize the biomedical waste at the selected concentration of ozone. The ozone rich atmosphere is exhausted from the processing chamber and then the sterilized waste is removed.
