ABSTRACT:
Various kinds of used and potentially infectious medical articles such as injection needles are first crushed into pieces to such an extent that the shape of the articles can not be visually identified. Subsequently, the crushed medical articles and particulate absorbent are introduced into a mixer and mixed and heated therein to a temperature above 180.degree. C. by use of a heater in combination with frictional heat generated as the mixer blade is rotated, whereby the crushed infectious medical waste articles are completely sterilized. The particulate absorbent serves to absorb any unpleasant odor or toxic gas which is generated from the crushed infectious medical articles during heating. In such manner, sterilization of the crushed infectious medical appliances and absorption of the toxic gas can simultaneously be achieved, and moreover, the resultant sterile admixture can be used as an aggregate for construction material such as concrete.
