<p>Environmentally harmful waste is hard to handle and the capacity for an economical handling is not sufficient. According to the invention such waste can now be worked up to a full worth fuel which can replace conventional fuels, which can be stored and has a specific composition and which gives little harmful air pollution, and a solid residue which can be deposited cheap and safe. According to the invention the waste is fractionated in centrifuges or cyclones (5, 10) into a solid part, in which the main part of the heavy metals in the waste are enriched and a liquid part containing oils, solvents and dissolved substances. The solid part containing plastics, pigments, insoluble oil residues, organometallic compounds, etc. is mixed, after drying (12) and optional grinding with other wastes, such as Cefyll R with which it can form a very sparingly soluble, monolithic compound and be deposited. The liquid part is used as a fuel.</p> |
