In the treatment of human faeces having a starting moisture content, the faeces are pressed between opposing pressing surfaces of rollers in a dryer, to press out at least some moisture from the faeces. The pressing surfaces are moved to leave an exposed layer of pressed faeces on at least one of the pressing surfaces which is then scraped. This produces partially-treated human faeces having a moisture content of not more than 20 wt %. The partially-dried human faeces may then be combusted. This fuel is fed substantially continuously into a combustor at a rate of 0.4-15 g/min combusted continuously over a time of at least 1 hour. In the combustor, there is a reaction chamber with a drying zone and a first combustion zone. The reaction chamber is orientable to permit gravity-assisted transit of the fuel from the drying zone to the first combustion zone. The drying zone has a drying zone grate configured to hold some of the fuel while combustion of other of the fuel occurs at the first combustion zone. A toilet may incorporate such a dryer and/or combustor.

Disclosed is an apparatus for drying a material, the apparatus including: an air-delivery enclosure with an air inlet and an air outlet through which forced air is directed toward the material; and an ultrasonic transducer connected to the air outlet of the air-delivery enclosure, the ultrasonic transducer including: a first inner surface; a second inner surface, the second inner surface facing the first inner surface, the first inner surface and the second inner surface defining an airflow path through the ultrasonic transducer; a first groove defined in a first inner surface, the first groove including a first flat portion; and a second groove defined in a second inner surface, the second groove including a second flat portion.

A pressing device having an endless conveyor which includes conveying elements connected to each other to form and endlessly revolving track. Adjacent conveying elements are pivotally connected together via pins forming pivot axes. A press roller is provided in a pressing zone to apply pressure to the material to be pressed, which is conveyed on the endless conveyor. Adjacent conveying elements of the endless conveyor have intermeshing fingers, and the pin connecting the conveying elements penetrates these fingers, such that in the pressing zone the conveying elements assume a pivot position with respect to each other in which the outer side of the endless conveyor forms a closed, plate-like surface without protrusions of recesses. The pressing zone follows a break open zone in the circumferential direction of the endless conveyor, and in the break open zone the endless conveyor is deflected such that the outer side thereof is concavely bent.
