Evaluate a mid-sized catering company's options for single-use plastic, paper, and reusable food packaging by applying a cradle-to-grave life cycle assessment. Test ability to define a functional unit and system boundaries, choose relevant impact categories (e.g., GWP, water use, eutrophication), model material production, transport, use (including washing cycles and infrastructure for reusables), end-of-life scenarios, run sensitivity/uncertainty analyses, interpret trade-offs, and make evidence-based operational recommendations.
