Treating ash and dust from incineration plants by coprocessing with hazardous waste and/or metallic scrap
A process for treating ash and dust (1) from incineration plants in which the ash and dust are co-processed with specific listed hazardous wastes (3). The wastes (3) are added (2) to enrich the mixture in certain valuable recoverable components such as metals. The mixture is smelted (5) with reducin...

| description | A process for treating ash and dust (1) from incineration plants in which the ash and dust are co-processed with specific listed hazardous wastes (3). The wastes (3) are added (2) to enrich the mixture in certain valuable recoverable components such as metals. The mixture is smelted (5) with reducing agent (6) to give a liquid metal phase (10) and a waste gas phase (12). Any remaining oxidisable components in the waste gas (12) are subjected to controlled afterburning (19). |
