Improving materials efficiency must play a role in decarbonizing metals production because these strategies are available to pursue now and, therefore, achievable along a shorter time horizon than more transformative processes such as novel production methods. In the face of an evolving scrap stream and shifts in product demand, industry-based recycling targets will not be achievable without coupling alloy design with considerations of emerging end-of-life scrap streams. Performance metrics must be broadened to include the ability for a new alloy to incorporate secondary material emerging from a dynamic scrap stream. Leveraging ever more powerful computational and data science tools, metallurgists can explore a broader range of compositional and processing dimensions, especially where opportunities are present to improve recyclability. This presentation will cover methods that investigate underexplored regions to guide the production of new alloys with endogenous links to include secondary material based on expected future flows of scrap.
