Abstract
Abstract A waste disposal system is disclosed which includes apparatus for treating water which has been used for cleaning, washing and for flushing toilets and for disposing of waste products by incineration. The total output of the system to the environment is then reclaimed wash water of tertiary treatment quality plus CO 2 and the ash resulting from the incineration of solid wastes. In alternative embodiments, systems designed for ships, multiple unit dwellings or small communities can operate on a substantially continuous duty cycle with full utilization being made, if desired, of the heat energy required for the incineration process, and for substantially reducing fresh water quantity requirements in all such installations through the use of recirculating toilets.
