The EU's 2025 mandate for separate textile collection necessitates effective regional ecosystem management. This case study examines orchestration in Linköping, Sweden, focusing on post-consumer textile collection and manual sorting. Following the mandate, collected textile volumes doubled, but quality decreased, overwhelming Non-Profit Organisations' (NPOs) sorting capacities. The Waste Management Company (WMC) is consequently adopting an orchestrator role, seeking new partnerships to manage increased material flows and coordinate actors. Findings highlight the critical need for public proactive public sector orchestration, including resource integration and relationship management, to navigate the operational challenges and complexities of circular economy transitions in the textile sector.
