Assess learners' ability to create a scalable circular-economy business model for a consumer-electronics product that minimizes e-waste by integrating sustainable product design (modularity, repairability, recycled/low-toxicity materials), reverse logistics (take-back, refurbishment, component recovery), recycling incentives (deposit-refund, trade-in), life-cycle assessment to quantify impacts, and international regulatory compliance (WEEE, RoHS, Basel, conflict minerals). Require stakeholder mapping, cost/revenue model, KPIs, implementation roadmap, and risk mitigation.
