The bowl includes a wall dividing the bowl into a first region configured to receive liquid waste and a second region configured to receive solid waste. The system also includes a first line in fluid communication with the first region to transfer the liquid waste from the first region, and a second line in fluid communication with the second region to transfer solid waste from the second region. A storage tank is coupled to the first line such that the storage tank is configured to receive the liquid waste from the first region via the first line.

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.

Abstract: A toilet. The toilet comprises an upper bowl defining a first fecal aperture, a lower bowl defining a second fecal aperture, a urine receptacle and a feces receptacle. The upper bowl defines a urine aperture. A raised barrier extends upwardly around a periphery of the second fecal aperture. When a diverter panel is closed urine flows from the upper bowl through the urine aperture into the urine receptacle or urine flows through the first fecal aperture, strikes an upper surface of the diverter panel, and through an opening between a lower surface of the upper bowl and the upper surface of the diverter panel into the urine receptacle. In a third path when the diverter panel is opened urine flows through the urine aperture into the urine receptacle, the raised barrier prevents urine flow into the feces receptacle through the second fecal aperture.

Abstract: A toilet.

Said main receptacle defining one or more urine apertures in a lower region thereof through which urine may flow out of said main receptacle downwardly into the urine receptacle, said main receptacle shaped to divert urine into the one or more urine apertures. Said main receptacle defining one or more fecal apertures in the lower region thereof through which feces and urine may leave the main receptacle and pass downwardly. Said one or more fecal apertures having a raised perimeter for preventing urine from entering said one or more fecal apertures, and said feces receptacle for receiving and storing feces that falls downward through the feces aperture.

Abstract: A portable, self-contained toilet is provided that does not require water, and produces its own energy without the need for an external source of power. The toilet includes and external housing for providing protection from environmental elements to components of the toilet and to human users of the toilet. A toilet bowl directs liquid and solid waste into a collection hopper. Once the hopper is full, a turntable or other rotary device is indexed to advance the waste filled hopper to an intermediary position. From there, the hopper is moved onto a burner, where the collected human waste is separated into liquid and solid waste. As a result of heating, the liquid waste turns to steam and is removed from the hopper, collected, filtered and the resulting distilled water stored. The remaining solid bio-fuel may be removed and disposed of or used as needed.

Abstract: A mobile sanitary urinal apparatus for truck drivers or others who do not have access to restroom facilities while traveling comprising a removable accumulation vessel mounted to interior or exterior of a motor vehicle is herein disclosed. The urinal is designed to be discretely used in the passenger compartment of tractor-trailer rigs, although it can be used discretely in almost any vehicle. It comprises a catheter-type receiver which attaches to plumbing thereby functioning as a urinal to receive urine from a user and directing it through the hose to a retention container. It is envisioned that the retention container would be emptied into a sanitary collection station or normal restroom when feasible. The urinal can be cleaned periodically using a provided sanitation kit with a flushing bulb and liquid cleanser that would be flushed through the system cleaning the valves, hoses, and container.

Abstract: An improved incinerating commode for the disposal of human waste through injection of a combustible fluid into the chamber where the waste is incinerated, separation of the urine component from the fecal component of human waste, and use of the urine component mixed with a cleaning fluid to steam clean and cool the chamber that incinerates the waste.

Abstract: A device in connection with a separation-type of toilet systems, i.e. having separate feces and urine reception means located beneath a seat opening, a urine receptacle debouching into the front part of the seat opening and a feces receptacle debouching into the rear part of the seat opening, as seen in the direction of the person assuming a sitting position above the seat opening. In accordance with the invention the toilet seat is located inside a toilet space, the headroom of which above and in front of said seat is sufficient to allow said person to assume a comfortable sitting position above said opening but at the same time insufficient to allow a standing position, thus preventing or making considerably difficult urination from in front of the seat opening.

Abstract: A system and method is disclosed for composting feces and treating. Human feces is collected within a composting retainer and exposed to sufficient air and water to allow the feces to compost, thereby forming compost product. Urine is collected within an urine treatment retainer which is at least partially partitioned from the composting retainer and wherein the urine is passed through a substrate supporting aerobic nitrifying bacteria, thereby nitrifying a significant portion of the ammonium ions in the urine to form liquid product. The compost product is suitable for subsequent use, such as fertilizer or for use in forming a mixture with soil to form topsoil.

Abstract: A new portable system is disclosed for composting feces and for treating urine includes a composting retainer which includes a composting means for exposing the feces to sufficient air and water to allow the feces to compost, thereby forming a compost product. A urine-treatment retainer with aerobic nitrifying bacteria disposed on a substrate whereby urine is treated by the bacteria, thereby forming a liquid product. A means is available for transporting the portable system.

Abstract: A urine flow meter including a toilet mounted collector is disclosed. The collector has a mouth portion which is dimensioned to fit within a toilet bowl and which has walls which slope downwardly and inwardly to a neck portion. The neck portion extends downwardly from the lower end of the mouth portion to receive urine directed into it from the mouth portion. An aperture is formed in the neck portion and a pressure sender has a lower end in communication with the neck portion. An upper end of the pressure sender is above the neck portion and is connected to a pressure transducer. Urine accumulates in the neck portion until the flow rate into the collector equals the flow rate out through the aperture. The accumulated volume of urine in the neck portion produces an air pressure within the pressure sender which is converted into an electrical signal by the pressure transducer. The pressure transducer output signal is suitable to be processed to provide critical urine flow data.
