N2 - Aluminum is a major construction material in light-weight vehicles. Today, recycling the aluminum content of end-of-life vehicles (ELVs) is based on dilution with primary metal and downcycling to cast engine blocks. The importance of the latter, however, is expected to lessen due to vehicle electrification. In this study we posit that by altering the common classification of aluminum alloys, it may become possible to deploy ELV scrap as a direct source for upcycling into new wrought alloys. We demonstrate this by examining possible compositions of an average EU car, a pickup truck and an electric car, and the corresponding dismantling scenarios.
