When it comes to climate change, circularity has become a major topic. Closed loops, reuse, recycling, and renewable materials are fashionable ideas in architecture and product design. In order to establish the new paradigm of circular design, this book introduces an urban and territorial dimension to the goal of transforming living spaces for resilience and sustainability. It proposes to use design-led research and design-thinking for analysis, concepts, strategies, and cooperative processes of transformation. Featuring case studies from all over Europe that relate creative narratives in urbanism to social and economic innovation, Circular Design aims to activate dynamic fields and networks of ideas, people, and spaces, oriented to circular principles.
