The use of waste fractions for co-combustion in an aluminium recovery smelter
Övrigt konferensbidrag, 2016

Fossil energy resources are widely accepted to be the main cause for the climate changes we are facing. Large efforts are therefore invested in finding alternative energy resources and to improve resource efficiency in order to reduce fossil CO2 emissions. For example, the recycling of used products and materials translates into large energy savings. Different product and materials are more or less suitable for material recycling. Fractions of products which are difficult to recycle may instead be suitable for energy recovery, i.e. the material may be used as a fuel which improves the cost and resource efficiency of the recycling process. In this work five different waste fractions were evaluated for co-combustion purposes in a secondary aluminium smelting process. The work has been carried out by performing detailed gas phase reaction simulations. Based on these simulations fuel alternative B seems to be the most promising alternative. However, it has also been concluded that further investigations toned to be made in order to eliminate some of the uncertainties identified in this work.
