Patent

CA 2601057

The invention consists of a discontinuous helical auger contained within a waterless biotoilet. The auger enables thorough turning of sawdust enclosed within a heated drum. Control of auger rotation works to maximize the biodegradation of human toilet waste through physical breakdown of organic matter, through stimulation of evaporation of the aqueous fraction, and through supporting a benign microflora to effect biodegradation. This discontinuous helical auger enables maintenance of a flat horizontal upper planar surface of the sawdust mass while maximizing aeration of the sawdust mass. The angle of the helical blade and discontinuities therein work to draw the organic matter very gradually toward the opposite end of the biotoilet from the toilet hole, maximizing dewatering and aerobic breakdown along the way.
