This patent describes a method for disposal of oil refinery sludges containing hydrocarbons, sediment, and at least about 5 percent water by weight in an operating rotary kiln comprising a heated, rotating cylinder containing in-process mineral matter, the rotary kiln having a firing zone in which fuel is ignited. It comprises analyzing the oily refinery sludge to determine its composition, providing the oily refinery sludge as a dried bulk granular material having an energy content of at least about 4,000 BTU per pound, and charging the dried granular material to the firing zone of the rotary kiln as a bulk material and burning the bulk material therein.
