Method for Processing Solid and Liquid Wastes from the Production of Vegetable Oil

A method for processing solid, organic wastes and waste water obtained in the production of vegetable oil, wherein the solid wastes comprise pressing residues of oil fruits or oil seeds and the waste water contains vegetable oil residues beside other organic impurities, which are present in the waste water in emulsified form, wherein the solid, organic wastes are comminuted and in a stirred, heated reactor mixed with the waste water to form a suspension, the pH value of the suspension is adjusted in the acidic range, the atmospheric oxygen is removed from the reactor by flushing with inert gas, the reactor is closed gas-tight and the suspension is heated to at least 170° C. and kept at elevated pressure for at least 0.5 hours, wherein the solid, organic wastes chiefly are converted to a solid material rich in carbon, and wherein the emulsion of waste water and vegetable oil residues is broken and the oil is sorbed by the obtained solid material rich in carbon, and wherein subsequently the suspension is cooled, removed from the reactor and separated into a solids and a waste water fraction.
