<p>The invention provides a method for utilizing liquid wastes, especially those that are toxic and harmful an in particular those in the form of sludge, sewage, paste and liquids. In the method provided by the invention a tank in which there is negative pressure is filled up to 50% of its capacity with liquid chemical wastes in the form of paint sludge. The tank is made to move with rotary motion and the sludge inside is treated with superheated steam at 150 DEG C until the sludge is turned into granulated material, after which sulphur polymer is injected into the tank being in continous motion. The motion of the tank and the injection of sulphur polymer are stopped after the granulated waste is completely coated with sulphur polymer. The granulated waste with sulphur polymer coating is poured into drums or moulded into construction elements.</p> |
