A comminuting apparatus includes a frame, a set of overlapping scissor rolls, a first drive motor, and a second drive motor. The frame has an enclosure with an entrance opening for receiving waste material. The set of overlapping scissor rolls is carried within the enclosure for rotation, including a first scissor roll and a second scissor roll. The first drive motor is coupled to the first scissor roll, and the second drive motor is coupled to the second scissor roll. The first drive motor is operative to drive the first scissor roll at a substantially variable operating speed. The second drive motor is operative to drive the second scissor roll in co-rotation at a substantially constant operating speed.
