WERKWIJZE VOOR HET OMZETTEN VAN ORGANISCH EN ANORGANISCH AFVAL IN MATERIALEN, DIE VAST ZIJN, INERT, EN ONOPLOSBAAR IN WATER.

摘要

Metal bodies which may be contained in waste are removed, whereafter the waste are crushed and homogenized so as to form a homonegeous pulverulent mass; said mass is pressed in the form a plurality of cylindrical granules and, finally, these granules are mixed with a pulverulent mixture of quicklime and calcium carbonate and are subjected to a heat treatment comprising an initial heating phase causing a sudden heating of the granules without exceeding the pyrolysis temperature of plastic materials possibly present in the starting waste mass. Thereby, solid, inert and water-insoluble granules are thus obtained which may be used for example as concrete or mortar granulate.
