<p>PURPOSE: To process the waste products at a minimum cost by shredding scrap adulterated by organic components into particles having a maximum size of 5 cm, converting the particles into solids and pyrolysis gas at about 550-600 deg.C in a pyrolysis stage, separating the solids into metals and pyrolysis coke in a mechanical processing state and adding an oxidizing agent or the like in a high temperature gasification stage. CONSTITUTION: The method for processing the waste products is comprised of shredding a metal scrap 1 adulterated by organic components into particles having a maximum size of 5 cm by passing it through a shredder 2, transfering the particles into a pyrolysis stage 3 which is operated about 550-600 deg.C to convert the particles into solids 5 and pyrolysis gas 4 by the pyrolysis, separating the solids 5 into metals 7 which is suitable for reuse and pyrolysis coke 8 in a mechanical processing stage 6, supplying the pyrolysis coke 8 to a high-temperature gasification stage 14 which introduces the pyrolysis gas 4 from the pyrolysis stage 3 and which is provided with supply lines for energy 23, an oxidizing agent 9 and optionally metallurgical coke 10, and subjecting the pyrolysis coke 8 to high-temperature treatment, resulting in a vitrified construction material 19 and energy 20. After purifying, heating gas 11 can be used for equipment 12 requiring a source of energy.</p> |
