Incineration: oxidation + waste-to-energy output of aluminium

Researchers at the Centro Nacional de Investigaciones Metalúrgicas (CENIM) in Spain studied the oxidation behaviour and waste-to-energy output of different semi-rigid and flexible aluminium packaging when incinerated.
They found that packaging with an aluminium lamina thickness of >50 μm did not fully oxidise. During incineration, the weight-for-weight waste-to-energy output of the packaging with thick aluminium lamina was lower than that of packaging with thin lamina. The calorific gain depended on the degree of oxidation of the metallic aluminium, but was greater than zero for all the packaging studied. An article about the research is published in Waste Management.
