“Over the past 20 years several studies have been carried out into the behaviour of metals during and after incineration in Waste-to-Energy (WtE) plants but little is known about one of the most well-known non-ferrous metals, aluminium. After iron, aluminium is the most abundant metallic component of incinerator bottom ash, originating largely from used aluminium packaging not collected separately. This fraction usually ends up in the remaining household waste fraction and is sent for incineration in most Western European countries. Today, most WtE plants extract non-ferrous metals from incinerator bottom ash (IBA) in quantities ranging from 0.5 to 3.0%, with aluminium being the largest component. The aluminium input into the incinerator is not exactly determined, for reasons outlined below.”
