Abstract: A paper shredder has a feed compartment, paper shredding implements and an auger disposed with a transfer tube, the auger having flights and wear plates on the flights to stabilize the auger within the transfer tube. The wear plates may be made of spark resistant material. The wear plates may also be replaceable. The auger may also be driven by a direct drive from a vehicle transmission drive shaft. A transfer truck for transporting materials to an off-site shredding facility has a frame mounted on wheels, at least one compartment mounted to the frame, the compartment comprising a top, a floor, sides, an ejector wall, an opening for receiving materials for shredding, and a door for offloading materials for shredding, the ejector wall capable of movement towards and away from the door to push out materials for shredding from the transfer truck. The floor of the transfer truck may be ribbed. The ejector wall may have a vertical portion and an angled portion adjacent the floor.
