An incinerating toilet is a type of dry toilet that burns human feces instead of flushing them away with water, like a flush toilet does.[1] Incinerating toilets are used only for niche applications.

Description

Incinerating toilets may be powered by electric, gas, dried feces or other energy sources.[2][3] They are used in environments where human waste cannot be otherwise dumped, or where normal toilets are too expensive or cumbersome to install. Such toilets gather excrement in a holding tank and then incinerate it, reducing it to pathogen-free ash. Some will also incinerate grey and black water created from showers and sinks.

Examples

In 2011 the Bill & Melinda Gates Foundation launched the "Reinvent the Toilet Challenge" to promote safer, more effective ways to treat human excreta. Several research teams have received funding to work on developing toilets based on solid waste combustion.[4] For example, a toilet under development by RTI International is based on electrochemical disinfection and solid waste combustion.[5] This technology converts feces into burnable pieces and then uses thermoelectric devices to convert the thermal energy into electrical energy.[citation needed]
