Abstract
The toilet bowl separately collects urine and feces for analysis or use in a composting device, waste digester, or to reclaim water. The toilet bowl includes a toilet bowl wall. Urine flows down the toilet bowl wall into a channel for collection. The channel surrounds an aperture into which feces may be deposited. Consequently, urine and feces are kept separate during collection. Both the channel and the aperture may be connected to conduits which may transmit material into analytical devices. The conduits may transmit material into digesters in appropriate amounts including controlling the amount of liquid added to solid material. Collected urine may be stored for water reclamation. Sensors may confirm the absence of fecal matter in collected urine or detect contamination. After separate analysis, feces and urine may be combined through connecting conduits then disposed of in the sewer system or sent to a composting device or waste digester.
