Technology to Convert Excreta to Valuable Products

Ian Gates and Michael Kallos of the University of Calgary in Canada propose to combine two well-established technologies - anaerobic micro-digesters and micro combined heat/power thermoelectric generation units - into a single portable unit that can consume human excreta to generate electricity, heat, methane, fertilizer and water. Each device will be designed to serve a single extended family.
