<p>A method is described which allows two hazardous waste products, namely PVC and electric arc furnace dust, both of which have negative commercial value, to be combined to produce an iron oxid e suitable for steel making, pure cadmium, lead and zinc and chlorine all of which can be sold. The heat generated during th e exothermic reaction may be used to generate electri- city which may be sold or used in plants where the reaction is carried out. The method can also be used for metallic scrap.</p> |
