Abstract
A natural aerobic biological waste conversion system for the decomposition of human waste particularly suitable for waterless on-site restrooms. A tank includes a chamber having a waste receiving bin defined therein, the bin being formed by baffles and a bulkhead so located within the chamber that air (oxygen) is directed over, under and through the decomposing material and a ventilation duct located at the bin lower region communicating with a vent assures effective oxygen exposure to the waste. The tank bottom is provided with a serpentine liquid waste flow path for extended exposure of the liquid to the circulating air for evaporation purposes, and the tank chamber includes a drying area for decomposed material prior to removal.
