Abstract: A known form of refuse treatment apparatus, such as that disclosed in U.S. Pat. No. 3,405,873, is improved by directing the non-pulverized refuse material emerging from the treatment drum to a furnace combusts the same. The heat of combustion is directed to a steam generating unit to thus create a supply of steam. One portion of the steam supply is directed to a steam turbine which serves as a power means for rotating the refuse drum. The other portion of the steam supply is introduced into the inlet end of the drum to admix with the refuse material being fed thereinto. The non-pulverized refuse material emerging from the outlet end of the drum can pass through a series of treatment steps as disclosed in my U.S. Pat. No. 3,802,631 in transit to the furnace.
