ABSTRACT:
Waste sludge that contains water, solids and oil, is mixed with a filter aid that has filter aid characteristics and a heating value of at least 1,000 Btu/lb. The admixture obtained is subjected to filtration yielding a high-Btu combustible material, useful as fuel. This combustible material, optionally after drying to remove water, is very suitable for use as fuel in a cement kiln.
