  • Publication number: 20110171073
    Abstract: In accordance with the present invention, a system and method is provided for producing a safely disposable end product from waste matter containing undesirable materials, such as infectious, biohazardous, hazardous, or radioactive elements. The method comprises the steps of providing a highly basic solvent, immersing the waste matter containing the undesirable materials within the highly basic solvent, and heating the solvent. The waste matter containing the undesirable materials is allowed to remain within the solvent until digested, thereby forming a solution void of any infectious or biohazardous elements and/or containing a concentration of radioisotope below the maximum permissible concentration (MPC) for release to a sanitary sewer as defined in applicable federal regulations.

  • Patent number: 7910788
    Abstract: A system and method is provided for producing a safely disposable end product from waste matter containing undesirable materials, such as infectious, biohazardous, hazardous, or radioactive elements. An apparatus is provided that immerses the biologically infectious waste material in a highly alkaline solvent which is then heated. The waste matter containing the undesirable materials is allowed to remain within the solvent until digested, thereby forming a solution void of any infectious or biohazardous elements and/or containing a decreased concentration of radioisotope.

  • Publication number: 20110048086
    Abstract: In accordance with the present invention, a system, method and apparatus is provided for chemically reducing waste. The apparatus includes a substantially alkaline-resistant vessel having a temperature sensor positioned in thermal communication therewith, a heater in thermal communication with the vessel, a substantially alkaline-resistant magnetic stir rod adapted to be positioned within the vessel, and a magnetic stirrer adapted to produce a rotating magnetic field within the vessel capable of spinning a magnetic stir rod positioned therein. The apparatus further includes a water inlet valve operationally connected to the vessel and a water outlet valve operationally connected to the vessel. An electronic controller is connected in electric communication to the heater, to the magnetic stirrer, to the water inlet valve, to the water outlet valve, and to the temperature sensor and is adapted to maintain the temperature of the substantially alkaline resistant vessel substantially at a predetermined value.
