<p>With the electrification of vehicles, less powertrain castings and more structural castings are needed. Powertrain castings were mainly produced from secondary alloys, made from post-consumer scrap. Structural castings have been almost completely made from primary alloys to guarantee the high purity and consistency needed for those safety critical castings. Today, not only post-consumer scrap, but also an increasing amount of pre-consumer/industrial aluminum scrap is coming to the market and needs to find new applications. Know-how in terms of scrap recycling, segregation and sorting, as well as melt treatment/cleaning practices have been improving significantly. This allows metalcasters to produce structural casting alloys with high recycling content and therefore low-carbon footprint, without negatively impacting their quality and performance. This paper describes the latest trends and developments on this topic and which alloys can be made with which carbon footprint, which types of scrap, and what are the limiting factors.</p> Graphical Abstract <p></p>
