Abstract: A system and process for treating solid and liquid wastes, where the solid waste is separated from the liquid waste in a chamber, the liquid waste is passed out of the chamber, the solid waste is converted to ash, a fluid such as liquid waste is introduced into the chamber and combined with the ash, and the ash and fluid are exhausted out of the chamber together. Preferably, the system includes the use of hot air to agitate the solids during their conversion to ash. Desirably, the system also includes a filter and means to swirl the liquid waste as it exits the chamber, so that the liquid waste evenly distributes the solid waste within the filter as the liquid waste is exhausted.
