This study develops a comprehensive circular economy–based reverse logistics network for apple by explicitly integrating agility and resilience considerations under mixed uncertainty. The proposed network encompasses multiple echelons, including farms, collection centers, recycling centers, animal husbandry units, and energy and compost demand points, enabling effective waste recovery and value creation. A multi-objective mathematical programming model is formulated to simultaneously maximize economic performance, minimize node criticality as a proxy for resilience, and enhance service levels as an indicator of agility. To address the inherent uncertainty in parameters, a robust stochastic–possibilistic optimization framework is employed. Furthermore, the model is solved using a recently developed method named the Fuzzy Multi-Choice Chebyshev Goal Programming with Utility Function (FMCCGP-UF) method. The practical relevance of the proposed approach is validated through its application to a real-world case study of the apple reverse supply chain in Iran. Results reveal that increasing processing and collection capacities improve economic outcomes while simultaneously strengthening agility and resilience. The network design leads to the establishment of recycling centers #2 and #5, as well as collection centers #1, #3, and #4. Critical nodes are identified as recycling center #2 (periods 2 and 5) and collection center #1 (periods 3 and 5) and collection center #2 (periods 1 and 5). The service levels achieved are 0.73 for animal husbandry units, 0.78 for compost demand points, and 0.69 for energy demand points. Furthermore, increasing processing and collection capacities improves economic outcomes while simultaneously strengthening agility and resilience. A higher proportion of recyclable products substantially enhances value recovery and service levels, albeit with implications for node criticality.
