Abstract
The toilet bowl separately collects urine and feces for analysis or other uses. The toilet bowl includes a toilet bowl wall with at least two holes in it. The first hole is a fecal collection aperture positioned below a user where a user may defecate into it. The second hole is a urine collection orifice through which a user's urine may flow. The two holes may be separated by a ridge which may act like a dam to inhibit cross-contamination of collected feces and urine. Conduits may connect to the two holes to direct the waste into analytical devices or containers for additional uses including composters and digesters which produce clean energy.
