Infectious medical materials are rendered harmless by heating heterogeneous medical materials having wet and dry portions with a radio-frequency electric field. The medical materials may be comminuted prior to heating. The medical materials are exposed to the radio-frequency electric field in order to heat the medical materials. The medical materials may include sorted medical or veterinary waste which after heat treatment may be recycled.

An apparatus for rendering infectious medical material harmless, comprising: a radio-frequency treatment unit for accepting medical material to be treated: means for transporting infectious medical material in closed bulk containers through the radio-frequency treatment unit; means for energizing the radio-frequency treatment unit with the time-varying electric field having a frequency below the frequency of microwave; and means for injecting inert gas into the radio-frequency unit thereby to sweep oxygen therefrom to avoid oxidizing heated medical material and to cause a flow of gas from a relatively cool portion of the radio-frequency treatment unit to a relatively warm portion and thereby to prevent any vapor which might have escaped from the medical material from condensing on cooler medical material entering the radio-frequency treatment unit.
