Scholars have recently debated the potential of the circular economy (CE) as a crisis response strategy; however, concrete examples demonstrating its effectiveness in such applications remain limited. This study addresses this gap by investigating how CE principles—narrowing, slowing, closing, and regenerating resource loops— can be integrated into post-disaster reconstruction and recovery, with a focus on the 2023 Kahramanmaraş Earthquakes in Türkiye. Using an exploratory qualitative research design, including an integrative literature review, workshop with 24 participants and 21 expert interviews, this study develops the Build Back Circular (BBC) framework. The framework proposes ten action strategies: (1) Upcycle, reuse or recycle post-disaster waste, (2) Integrate circular design principles, (3) Introduce circular policies, (4) Leverage digital technologies, (5) Raise awareness and expand knowledge, (6) Drive the market with circular business opportunities, (7) Involve local communities, (8) Improve cooperation and collaborations, (9) Integrate CE principles into post-disaster urban development, and (10) Stimulate the use of healthy, local, and biobased materials. These strategies aim not only to enhance resource efficiency and resilience but also to address the social dimensions of CE, promoting an inclusive recovery. Successful implementation requires a collaborative ecosystem of government, municipalities, academia, the construction sector, and civil society. By bridging the fields of CE and disaster management, this research offers valuable insights for policymakers, researchers, and practitioners to integrate CE into post-disaster reconstruction and urban development processes. Beyond Türkiye’s recovery, it aims to support global disaster risk frameworks (e.g., UN’s Sendai Framework), enhancing crisis management through a CE lens.@en

The early 2020s have been characterized by multiple convergent crises, including the Covid-19 pandemic and economic fallout of mitigation measures, Russia's invasion of Ukraine, and the ongoing sustainability and climate change crisis. This article discusses how the concept of the circular economy can inform responses to such crises by addressing four elements of a socio-economic system: technological innovation, supply chains and markets, public policy, and consumer behaviour. Synthesizing emerging insights from the scholarly and policymaking arenas, the article identifies the following ways that the circular economy concept can be effectively framed as crisis response: focusing on circularity in a more holistic way, adopting global value chains as the primary unit of analysis, pinpointing specific circularity aspects like drivers and barriers in value chains and business models, and extending the prevailing focus on technical aspects and material flows to often overlooked trade and geopolitical considerations. This discussion aims to articulate lessons for industry, policymakers, and scholars in leveraging a circularity approach to address the world's most pressing issues.
