Recycling is important in the aluminum industry. Removal of contaminantssuch as the coat and organic materials- applied for protection and appearancearethe tail that wags the recycling dog. Successful removal of contaminantsfrom scrap would ensure that more aluminum be recycled, minimize lossesand prevent downgrading of the resource. Performing decoating in a closedsystem, efficient cleaning of the evolved gases and reuse of the energy ispossible. Motivation for removal of contaminants on aluminium scrap willbe presented. A sum up of fundamental studies will be given. De-coating maybe described as two distinct regimes: Scission and Combustion, regardless ofmetal substrate and coating. This is studied by methods: (i) mass and enthalpychange together with the off-gas composition recorded simultaneously and(ii) hot stage microscope to give a visual record of the surface. In conclusiona more fundamental understanding of the decoating process should enablethe metallurgical industry to process post consumer aluminium scrap in amore efficient and sustainable manner.
