ABSTRACT:
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.
