Abstract
A waste material processing system includes a closed container for holding waste material having a first passage in which the waste material flows in a first direction, the first passage having first and second ends, the first end including an inlet for waste material, a second passage in which the waste material flows in a direction opposite the first direction, the second passage having first and second ends, the second end including an outlet. The first passage is separated from the second passage by a divider, the second end of the first passage being adjacent the first end of the second passage, and the first end of the first passage being adjacent the second end of the second passage. A heating device is positioned in the first passage and/or the second passage to heat the waste material with a gas and to induce the waste material to move in a corkscrew-like fashion.
