Circular Design & Material Passports
The circular economy for the built environment — the end of take-make-waste (the building as a material bank), circular-economy foundations (what it is, the R-ladder, technical and biological cycles, why recycling is not circularity), circular design strategies (build less/long, adaptability, design for disassembly, layers and reversibility), materials in a circular world (reused, recycled, bio-based), reuse and the existing building (audits, deconstruction, structural reuse), material passports (what they are, what goes in them, standards, buildings as material banks), measuring circularity (indicators, circularity vs carbon, provenance, targets), the circular supply chain (reuse markets, logistics, product-as-service, procurement), codes/value/barriers (approval for reuse, the business case, insurance and liability), reality/limits/honesty (circular-washing, when circular is not better, scale and policy, justice and the informal recyclers), and practice and the future. Rigorous and honest — circularity is largely aspirational, recycling is not circularity, and much circular claim is greenwash — for architects, interior designers and students. Defers structural reuse certification, code approval, warranties, insurance and contracts to qualified engineers, the governing codes (NBC India), certified testing and legal/insurance professionals, treating rates and costs as illustrative.

Module 0 · The End of Take-Make-Waste0.1 · The Building as a Material Bank
The circular economy reframes a building not as a final resting place for materials but as a temporary store of them - a material bank. This lesson contrasts linear take-make-waste with circular thinking, introduces designing for reuse and the material passport, and is honest about the greenwash.

OpenWhat this course covers
The through-line- 1Circular Economy Foundations. The core concepts: what the circular economy is, the R-ladder from refuse to recycle, technical and biological cycles, and why recycling is not circularity.
- 2Circular Design Strategies. Design is the biggest lever: build nothing/less/long, design for adaptability and longevity, design for disassembly, and layers, connections and reversibility.
- 3Materials in a Circular World. Choosing well: choosing circular materials, reused and reclaimed materials, recycled and secondary materials, and bio-based and regenerative materials.
- 4Reuse & the Existing Building. The richest material mine is what already stands: the existing building as resource, pre-demolition and material audits, deconstruction not demolition, and structural and component reuse.
