ABSTRACT OF THE INVENTION Apparatus for and method of thermally decomposing wastes laden typically with organic solvents, other organic liquids and soluble organic materials, by first extracting such wastes in a pressure vessel using a fluid extractant in which the organics are soluble, thereby producing a fluid extract of the organics in the extractant fluid and a non-extracted residue of reduced BTU/lb value. The extractant fluid, typically propane, is preferably a gas at ordinary conditions of temperature and pressure but in the pressure vessel means is held to conditions of temperature and pressure sufficient to render the extractant fluid a solvent for the organics. Means are provided for separating the residue from the organics extracted from the waste material, and the residue is burned typically in a solids incinerator The fluid extract is separated into an extracted organics fraction and an extractant fraction, the latter being recycled for use in the pressure vessel. The extracted organics fraction is employed as auxiliary fuel for either the solids incinerator or ` for an afterburner to which the flue gases from the incinerator are fed for further, high temperature incineration.
