Is Silicon the Root of all Evil?
Welcome to our 21st Gold Nugget, “The Kings of Scrap”, with Erik Petré from Stena Aluminium. In this episode, we discuss the sustainability of aluminium alloys. You might be surprised, but the major contributor to the carbon footprint of secondary alloys is not the recycling process; it is the silicon you must add.
As the title suggests, Stena Aluminium is the King of Scrap, so they know how to achieve low carbon emissions for high-quality casting alloys. Erik shares that in the podcast with us and focuses on the challenges of secondary Gigacasting alloys.
