| Abstract Scope |
The growing availability of post-consumer aluminium scrap from used beverage cans (UBCs) presents an opportunity to reduce the carbon footprint of packaging sheet production. Yet UBC scrap falls between AA3104 and AA5182 specifications, requiring alloying and primary dilution additions during remelting, which limit the achievable CO₂ reduction. A computational framework is presented that minimizes lifecycle CO₂ for recycle-friendly alloy design while ensuring mechanical performance. Alloy composition is linked to strength via a microchemistry-aware, three-internal-variables flow model (3IVM+) coupled with a CALPHAD-based process model, enabling secondary can body (CBS) and end stock (CES) gauge calculation. Scrap quality, primary additions, and electricity are assessed against CO₂ intensities, accounting for thermodynamically expected metallurgical losses, to maximize recycled content. Applied across a parametric Al–Mn–Mg–Fe–Si composition space, the framework resolves the gauge–recyclability trade-off as a Pareto exchange curve, where significant CO₂ reductions are achievable with recycle-friendly alloys without compromising processability. |
