FREMGANGSMAADE TIL OMDANNELSE AF ORGANISKE OG UORGANISKE AFFALDSSTOFFER TIL FASTE, KEMISK INAKTIVE OG VAND-UOPLOESELIGE MATERIALER

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.
