Circular Aluminium: Closed loops and the future of retrofit

Respecting materials is essential to credible circularity in construction yet current legislation fails to demand low-carbon or post-consumer metals. This gap is expected to close as policy evolves but progress on such regulation is slow. Using the example of a central London office retrofit this discussion will focus on the principles that shaped its low‑carbon strategy, the successes and learnings. The discussion explores why respecting materials is essential to credible circularity, and how current legislation fails to demand low‑carbon or post‑consumer metals; a gap expected to close as policy evolves. The panel will cover the challenges of downcycling, particularly where, once downcycled, aluminium alloys can never be upcycled again, and the need to maintain high material quality, highlighting the importance of closing the loop, reducing waste and treating metal as a resource we are all responsible for stewarding.  Chairperson Martyn Wright, Project Consultant - TECHNAL Speakers Sarah Keetch, Senior Sustainable Design Specialist - Orms Will Jarrett-Kerr, Director - Opera Helen Collarbone, Group Sustainability and Systems Associate Director - Deconstruct UK
