The excreta is mixed with water to produce a slurry and even out variations in the material utilised, and the slurry is thickened to a sludge and then to a solid, which is fragmented and passed through a micro-wave radiation dryer and steriliser: the liquid expressed in thickening is recycled, and steam evolved in sterilising is likewise recycled. |
