A mobile self-contained apparatus and process for grinding, grating, macerating, chemically disinfecting, and drying infectious waste material on-site is disclosed. A trailer (10) contains a hopper (27) and a system of grinder/graters, enclosed conveyors, drying and filter apparatus, and sources of power, chemical disinfectant, and fresh water. Bagged infectious waste material in a cart (C) is lifted and dumped into a hopper (27), fed to a first grinder/grater (28, 29), ground and grated into particles, immersed in a sodium hypochlorite (hypochlorous acid) chemical disinfectant solution, and conveyed by an enclosed upwardly inclined screw conveyor (34) to a second grinder/grater (43). The particles are sprayed one or more times with the disinfectant and thoroughly mixed together as they are conveyed in the inclined conveyor (34) into the second grinder/grater (43) operating at a higher speed than the first and further ground, grated, and macerated into smaller particles, and air dried to produce a dry confetti-like material which is unrecognizable as to the source. The confetti-like material is conveyed by an enclosed horizontal screw conveyor (45) to an enclosed vertical screw conveyor (47) where it is passed upwardly to an enclosed rotatable discharge screw conveyor (50) which discharges the confetti-like material into a receptacle. The enclosed system operates under negative pressure produced by a suction fan which draws the air within the system through a hepa-filter (40) to remove chemical fumes, airborne dust, odors and bacteria.read more

Batch treatment process and apparatus for the disinfection of infectious waste
TL;DR: In this paper, a process and apparatus for batch treatment of infectious waste material in a fluidized bed reactor utilizing gas oxidation, preferably ozone gas diluted in air, is described and evaluated.
Patent
Waste disposal system
TL;DR: A waste disposal system for treating and disposing of infectious waste articles in a substantially controlled, closed, aseptic environment is described in this paper, where a waste delivery conveyor transfers waste articles from an input region to preliminary waste processing apparata for preliminarily fragmenting the waste for further treatment by the system.
Patent
Aggregate for construction material from infectious medical waste articles
TL;DR: In this article, injection needles are first crushed into pieces to such an extent that the shape of the needles can not be visually identified, and then they are mixed into a mixer and heated to a temperature above 180° C. by use of a heater in combination with frictional heat generated as the mixer blade is rotated.
Patent
Waste treatment system
TL;DR: In this paper, a system for the treatment of infectious waste including apparatus for receiving, shredding, disinfecting, and separating waste material is described, where a manually operated entry device provides input for quantities of solid waste into a feeding channel wherein a feeding ram moves the waste onto a series of shredding disintegrators which achieve material size reduction.
