Abstract: Improved apparatus and method for on-site disposal of waste material including trace chemo, expired pharmaceuticals, and sharps, without the use of chemicals or incineration, and without requiring the waste material to be packaged and shipped to a location where incineration is allowed. The waste material is dropped into a high temperature crucible. The crucible is heated to at least 1,400 degrees Fahrenheit by inductive heating to disintegrate the waste material. The crucible is filled with nitrogen which depletes any oxygen entering the crucible to prevent oxidization of the waste material in the crucible.

Abstract: A waste treatment system shreds waste material into small pieces and soaks the pieces in a liquid disinfectant. The system includes a feed hopper, a shredder, a wetting area, an air operated pump, a dwell area, vibratory de-watering apparatus, and a de-watering auger. Unprocessed waste material is dumped into the feed hopper. The feed hopper feeds the unprocessed waste material into the shredder. The shredder includes a rotor and anvil for shredding the unprocessed waste material. The shredded material falls into the wetting area where the shredded material is wetted with the liquid disinfectant to create a wetted slurry. The wetted slurry is advanced by an air operated pump into a dwell-area for an additional three to four minutes of wetted time in the dwell-area before entering the vibratory de-watering apparatus and then the auger. The total wetting time allows the waste material to be completely disinfected.

Abstract: An infectious waste treatment system uses a chlorine dioxide based liquid disinfectant generated from combining precursors comprising sodium chlorite, acid, and bleach. The waste is ground into small pieces and soaked in the liquid disinfectant. The chlorine dioxide is generated by combining dilute aqueous precursors with a flow of the liquid disinfectant into a circulation pump. A preferred set of precursors comprises an approximately 25 percent aqueous sodium chlorite solution, an approximately 12 percent to approximately 50 percent citric acid solution, and an approximately 12 percent industrial bleach (sodium hypochlorite) solution such as Clorox® bleach. A continuous gas monitoring system measures the concentration of chlorine dioxide in the liquid disinfectant and commands the chlorine dioxide generator to generate chlorine dioxide when necessary.

Abstract: A waste treatment system grinds waste material into small pieces and soaks the pieces in a liquid disinfectant. The system includes a hopper, a grinder, a main solution tank, and an auger. Unprocessed waste material is dumped into the hopper. The hopper feeds the unprocessed waste material into the grinder. The grinder includes a rotor and anvil for grinding the unprocessed waste material. The ground material falls into the main solution tank where the ground material is wetted with the liquid disinfectant. The wetted waste is carried from the main solution tank by the auger and spends an additional two to three minutes of wetted time on the auger before entering a de-watering section. The total wetting time allows the waste material to be completely disinfected.
