A system and method for processing solid waste products includes an autoclave, a combined heat and power generation system and a water treatment system. Water in the solid waste products is vaporized to raise steam, by heating the autoclave. Waste liquids, steam and cellulosic material are removed from the autoclave. The cellulosic material is combusted in the heat and power generation system, which generates steam and electricity, with the steam recycled to the autoclave. The steam and the waste liquids are processed in the water treatment system, with the cleaned water cycled to the heat and power generation system to be converted into steam.
