Abstract

A waterless toilet system with fece and urine separation, odor and vermin seal, thermal and biological disinfection, and gas ozonation includes a system of components. The feces and urine are kept separate by a ridge separating the urine bowl from the fece chute. The seat forms a temporary seal with the platform, and the lid forms a temporary seal with the seat when closed. The rest of the components are sealed to keep vermin outside and odors inside, with the exception of a gas vent hose with a screened opening. Biological disinfection is achieved with phage focused on human pathogens. Thermal disinfection of human pathogens is achieved by insulating the fece receptacle and containing metabolic heat. The air in the toilet is ozonated by electrical discharges from a hand operated device.

Claims

1. A waterless toilet that keeps feces separate from urine and is sealed against vermin ingress or egress and gas or odor release near the toilet when the lid is closed.

2. Said toilet of claim 1, wherein the toilet seat is temporarily sealed between the toilet platform and toilet seat.

3. Said toilet of claim 1, wherein the toilet seat lid is temporarily sealed between itself and the toilet seat.

4. Said toilet of claim 1, wherein the fece collection bag is temporarily sealed to the fece chute.

5. Said toilet of claim 1, wherein the urine receiving bowl or subsequent conduit are temporarily sealed to the urine collection tank.

6. Said toilet of claim 1, wherein one or more conduits vent the gases inside the toilet to the outdoors or other distant locations.

7. Said conduits of claim 6, wherein a mesh on the distal end of the conduits prevents the ingress of vermin.

8. A waterless toilet that keeps feces separate from urine and thermally insulates the fece receptacle.

9. Said toilet of claim 8, wherein the fece receptacle is thermally insulated by a foamed material and or a thermal radiation shield and or an air gap.

10. Said toilet of claim 8, wherein the fece receptacle is lined on the inside by a removable bag.

11. Said toilet of claim 8, wherein the fece receptacle has a solar absorber or solar window.

12. Said fece receptacle of claim 11, wherein a solar reflector-concentrator or lens directs additional sunlight onto the solar absorber or solar window.

13. A waterless toilet that uses phage to kill micro-organisms in the feces.

14. Said phage of claim 13, which can kill bacteria, protozoa, helminthes, and fungi that are toxic to humans or can decompose the combustible organic components of the feces, examples being E. Coli, Shigella, Salmonella, Vibrio (Cholera), Typhus, Clostridium, Bilharzias, etc.

15. A waterless toilet that uses an ozonator to deodorize the gases inside the toilet.
