This session aims to delve into the sustainable selection of circular economy solutions and business models, with a specific focus on the environmental and economic impacts of reuse and sharing. The session will bring together researchers evaluating diverse circular systems, including rental programs for clothing, reusable beverage cup and food container systems, shared-use laundry facilities and other similar initiatives. Through a comprehensive analysis grounded in Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA), the session will explore the potential benefits and challenges associated with these circular systems.

By going beyond traditional recycling practices, the session will shed light on innovative approaches that prioritize reuse and sharing as viable alternatives. These approaches extend product lifespan, reduce waste generation, and minimize resource consumption, thereby mitigating environmental impacts. Simultaneously, they present unique economic challenges, fostering the development of new business models and generating value from underutilized assets.

Furthermore, the session will emphasize the significance of these circular systems in the context of urban sustainability. Leveraging on efficiencies of densely-populated urban settings, promoting local resource loops, and reducing dependence on linear supply chains, circular systems can enhance urban resilience, ensuring the availability of essential resources even in the face of environmental uncertainties.

Join us in this special session as we explore the transformative potential of circular systems, navigating the environmental and economic impacts of reuse and sharing, and envisioning a more sustainable future.
