A process for recovering organics and inorganics from waste material with a specific object of preparing the separated organic fraction for the production of ethanol wherein rigid organic matter becomes soft when subjected to heat and pressure. The process is carried out by first, feeding the waste material into a perforated container mounted within a closed chamber. Next, the waste material is agitated and subjected to heat and pressure which sterilizes it and softens the organics contained therein. After heating under pressure, the pressure is suddenly released from the chamber which forces the softened organics outwardly of the container, thus separating them from the inorganics for further processing to recover fuels and animal feed supplements.

The process of treating waste material for the separation and recovery of organic matter comprising fermentable vegetable material and inorganic matter wherein rigid organic matter becomes soft when subjected to heat and pressure, comprising carrying out the following steps in the sequence named: (a) feeding said waste material into a container having perforations therein and mounted within a closed chamber in spaced relation to the inner surface of said closed chamber, (b) agitating said waste material while in said container, (c) subjecting said waste material in said container to heat under a pressure ranging from approximately 20 psi to 100 psi for a period ranging from approximately twenty minutes to two hours to sterilize said waste material and soften said organic matter contained therein, and (d) releasing the pressure from said chamber suddenly to thus force the softened organic matter outwardly of said container through said perforations, so that said organic matter is separated from said inorganic matter in said container.
