At Tiny Houses Revolution we have multiple environmentally friendly options when it comes to toilets. As well as composting toilets we offer Incinerating toilets that use electric heat to burn waste into a small amount of bacteria-free ash (about a tablespoon per use). Both systems are virtually odor-free and operate with little or no water, making them ideal for unheated areas susceptible to freezing.
Then the toilet fires up. Flushing is handled by some type of dry method, like an auger (a large screw) that turns to push the waste into the incinerator. A propane, diesel, or natural gas tank feeds into the incinerator. The incinerator injects fuel, ignites your waste, and burns it. Like composting toilets, these toilets can be self-contained or remote, putting the incinerator either inside or outside of the toilet.
