ABSTRACT various kinds of infectious medical waste articles such as bloody injection needles or the like are first crushed into pieces to such an extent that a shape of the crushed infectious medical waste articles can not visually be identified by anyone. Subsequently, the crushed infectious medical waste articles and pulverized catalyzer are introd- uced into a mixer so that a mixture of the crushed infect- ious medical waste articles and the pulverized catalyzer is heated in the mixer up to a temperature higher than 180 °C by activating heating means while generating frictional heat as a blade is rotated in the mixer, whereby the crushed infectious medical waste articles are completely sterilized in a hot atmosphere having a temperature higher than 180 °C. The pulverized catalyzer serves to absorb an unpleasant odor and a toxic gas which are generated from the crushed infect- ious medical waste articles in the mixer at a temperature higher than 160 °C. In such manner, sterilization of the crushed infectious medical waste articles and absorption of the toxic gas can simultaneously be achieved, and moreover, the resultant mixer of the crushed infectious medical waste articles and the pulverized catalyzer can be reused as an aggregate for construction works such as concrete or the like.
