The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

An electrostatic separation device (is for a mixture of granules of different materials. The device includes a separation chamber having an inlet and delimiting an inner volume and a collection device for granules placed in the inner volume, opposite the inlet. At least two pairs of electrodes are successively placed in the elevation direction in the inner volume, between the inlet and the collection device. Each pair includes an anode and a cathode, placed on either side of a central axis extending in the elevation direction. At least one generating system is suitable for applying a difference in electric potential between the anode and the cathode of each pair.
