AbstractThe circular economy has emerged as a powerful solution to address environmental and socio-economic challenges in urban areas. As cities continue to grow and face increasing resource demands, adopting sustainable practices becomes critical to promote resource efficiency and improve the well-being of urban communities. This study aims to assess the effectiveness and feasibility of circular economy strategies at the urban scale, focusing on urban design and resource management. By examining successful case studies from four cities, valuable insights will gained into implementing circular economy practices in urban planning, such as waste management, renewable energy, and sustainable architecture. The comparative analysis of these cases will allow an assessment of the different approaches taken by each city and their impact on the sustainability and resilience of urban environments. This study aims to inspire and guide future urban development and promote sustainability and resilience in European cities by highlighting successful examples of circular economy implementation. Ultimately, this study aims to provide a comprehensive understanding of the role of circular economy principles in urban environments, highlighting their potential to promote sustainability and resilience. Through four study cases, this study will illustrate The tangible outcomes and real-world implications of adopting circular economy practices in urban landscapes.
