Patent ID: 7078229

Claim:
An organic waste material processing system for the anaerobic digestion of high-solids waste, the system comprising: a closed container for holding high solids waste material for the digestion of the high-solids material, the closed container including 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, and 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 being 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, the digestion producing sludge and methane gas during the digestion of the high solids waste in the container; a sludge drying device for receiving sludge from the container and for processing the sludge to produce a useful fertilizer; a turbine producing heated exhaust, the turbine being fueled by methane gas produced in the container, and having an exhaust outlet for discharging heated exhaust; and the exhaust outlet being connected to the container to heat waste in the container.
