ABSTRACT:
A continuous method for shredding waste material, particularly medical waste material, includes continuously loading the waste material into a hopper; passing the waste material into a continuously running primary shredder; initially shredding the waste material in the primary shredder; passing the initially shredded material into a continuously conveying screw conveyor wherein the initially shredded material is mixed together; conveying the mixed material into a continuously running high speed shredder for further shredding; passing the further shredded material into a turbo blender for additionally reducing the particle size of the shredded material; removing the shredded material by conveyor to a discharging area, and discharging the shredded waste material to a receptacle. The apparatus used for shredding the waste material includes a closable hopper for receiving the waste material; a primary shredder for receiving waste material from the hopper which includes a plurality of blades for initially shredding the waste material; a screw conveyor for mixing the material before passing the material to a high speed shredder; a high speed shredder having cutting blades for shredding the mixed material which is then passed to a turbo blender for further mixing and breaking down the shredded, mixed material. The method includes sterilizing the waste, if needed, and sterilized, shredded waste material is discharged to a receptacle.
