Circularity is often narrowed down to reuse and recycling, but on a systemic level it is about staying within planetary boundaries. This concerns energy, materials, waste ánd emissions: the whole picture. We start our problem analysis at planetary level, and from there we zoom in to global economy, spatial planning, buildings, elements and components, materials, The lectures of this course will give you a theoretical introduction in key concepts while the assignments address application. Finally, the course invites and allows participation in the follow-up Circularity Research a/o Design Project (7XC2M0).
