Abstract
A method for treatment of human excrement comprises the following steps: (1) providing a chamber (5) having a top opening through which excrement enters the chamber (5); (2) allowing solid excrement to form a layer on a porous plate (6) inside the chamber (5) by gravity wherein excrement is stored firstly at front storing region (13) and secondly at rear storing region (14), and allowing urine to fall down into the urine storing region (15) through perforations in the porous plate (6); (3) ventilating the interior of chamber (5) by a ventilation system, and providing an indirect heat source (7) inside the chamber (5). 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).
