Managing secondary production processes for aluminum auto-shred scrap is primarily important considering the projected demand increase for aluminum alloys in the transportation industry. This end-of-life, mixed metal stream must be recovered and recycled effectively and efficiently to ensure infinite lifetime involving a broad distribution of reuse applications determined by alloy chemistry. Issues preventing the aforementioned distribution include proper understanding of the sortable chemical composition in this mixed scrap and the removal of carbon-based impurities in the form of free polymers, oils, lubricants and paints/coatings by such methods that recover energy from the by-products formed. The developing Aluminum Integrated Mini-mill concept will utilize proper inline processes to sort, clean, re-melt and cast multiple secondary aluminum alloys from auto-shred scrap. This work focuses on characterizing aluminum auto-shred in terms of metallic chemistry and through thermally analyzing the organic content to aid the development of intelligent sorting systems and waste-to-energy cleaning processes, respectively.
