Test the ability to design, execute, and interpret a comparative life‑cycle assessment (LCA) of single‑use versus reusable packaging within a defined regional supply chain—including defining system boundaries, selecting impact categories (e.g., GHG emissions, water and energy use, waste), quantifying production, transport, cleaning/processing and end‑of‑life stages, performing sensitivity analysis on reuse cycles and return rates, and deriving management or policy recommendations based on trade‑offs and uncertainty.
