Abstract: A waste processing machine according to the invention is ideally suited for reducing virtually any products. The waste processing machine includes a rotor having multiple processing tools pivotally mounted thereon wherein each tool is adapted to self-limit the depth of the cut into the waste material. In addition, the pivotally mounted processing tools are staggered and spaced along the length of the rotor so that a limited number of tools will contact the waste product at any one point in time. Once the processing tool cuts or otherwise reduces the waste product to smaller bits of waste material, the bits are drawn out of the rotor system by screens having angled surfaces formed thereon.
