Abstract

An apparatus (A) for converting unconsolidated medical waste into a non-hazardous medical waste residue, which apparatus has an improved cutter assembly provided by a rotating cutter assembly that has revolving teeth (R, R') disposed at an oblique angle relative to the path of travel of the rotating teeth and to the stationary cutter assembly (F, F') to force the waste material between the revolving teeth (R, R') and fixed teeth (F, F'). An auger (15b, 25) moves the waste through the housing (10, 12) longitudinally to keep pressure on the opposing fixed and revolving teeth (F, F', R, R') while grinding the material into a reduced particle size to facilitate its disposal or storage.
