Abstract: A waste disposal system and method which incinerates solid human excrement evacuated into a toilet bowl employing a reusable chemical flushing liquid. The liquid discharges into an individual holding tank and thereafter is reusable for additional flushes until the solid excrement in the individual holding tank reaches approximately a predetermined level which usually is determined by the number of flushes. Then the collected human waste is discharged into a main collection holding tank where the solid excrement along with some of the chemical liquid rises until a predetermined level is reached. Subsequently, and upon the simultaneous occurrence of several triggering conditions, the solid excrement and liquid present in the main collection holding tank are run through a comminutor which returns such mixture to the main tank from which it is again passed to the comminutor and back to the tank in a closed cycle, a sufficient period of time being allotted to reduce such solid excrement and the chemical liquid to a gelatinous consistency. When this consistency is reached, the same being determined by the passage of a given period of time, and if the same triggering conditions still prevail, the comminuted mixture from the closed cycle is bled off into the exhaust of the engine used to power the conveyance, the comminution being continued during such discharge.
