Abstract: This disclosure provides a composting system and method. The system comprises: (a) a container configured to contain a composition and comprising (i) insulated walls, (ii) an air intake and (iii) a vent; and (b) a composition contained in the container. The composition comprises aerobic microorganisms, a carbon source and a nutrient source sufficient to support growth of the aerobic microorganisms. The container is sufficiently insulated so that heat generated by aerobic respiration is sufficiently retained in the container to maintain a heat gradient in the container. The container is dimensioned to generate a stack effect that moves air into the air intake, through the composition and out the vent. The moving air provides oxygen to support growth of aerobic microorganisms, making the stack effect self-sustaining as long as a carbon source and nutrients last. The insulation can maintain temperatures in the composting cell sufficient to kill pathogenic microorganisms.

A device for treatment of human excrement comprises the chamber (5), the porous plate (6) with the front storing region (13) and the rear storing region (14), the urine storing region (15), the ventilation system and the indirect heat source (7).

Abstract: A portable, self-contained toilet is provided that does not require water, and produces its own energy without the need for an external source of power. The toilet includes and external housing for providing protection from environmental elements to components of the toilet and to human users of the toilet. A toilet bowl directs liquid and solid waste into a collection hopper. Once the hopper is full, a turntable or other rotary device is indexed to advance the waste filled hopper to an intermediary position. From there, the hopper is moved onto a burner, where the collected human waste is separated into liquid and solid waste. As a result of heating, the liquid waste turns to steam and is removed from the hopper, collected, filtered and the resulting distilled water stored. The remaining solid bio-fuel may be removed and disposed of or used as needed.
