The present invention relates to a waste disposing apparatus that, rather than using incineration, uses a system wherein heat is applied to a magnetic field generated by compounded granulated ores to promote the occurrence and activation of plasma, resulting in the maintenance of a high temperature in the disposing apparatus that is sufficient to subject to a high heat consumption disposing the waste placed therein. The waste disposing apparatus of the present invention comprises a main body of a rectangular shaped waste disposing apparatus, a waste input port and a shutter located on top thereof, an opening located near the bottom of a side face of the main body for inserting a heating material there into, and a plurality of pipe-inserting holes located in peripheral side faces thereof; wherein a plurality of pipes are inserted and fitted to all of the pipe-inserting holes in the direction of a hollow inside of the main body; and compounded granulated ores generating a magnetic field are placed on the base of the plurality of pipes located on the outside of side walls of the main body and on the bottom face of the main body.
