Closing the Loop: The Architect's Guide to Recycled Aluminum

Aluminum is a widely used architectural material due to its strength, durability, and infinite recyclability—but its environmental impact varies substantially depending on its source. This program equips architects and design professionals with the technical knowledge needed to reduce embodied carbon through effective aluminum specification.
The session explores the full aluminum recycling process, the characteristics and limitations of secondary aluminum, and how alloy selection, surface quality, and structural behavior influence design outcomes. The participants will learn about the difference between post‑consumer and pre‑consumer recycled aluminum and what questions to ask to ensure to specify the most sustainable aluminum into projects.
Attendees will also learn about the challenges and opportunities within the U.S. aluminum supply chain, including the large volume of scrap exported overseas despite its potential to serve domestic, low‑carbon manufacturing needs. Through real‑world examples and data‑driven analysis, the course demonstrates how increased material circularity supports emissions reduction and industrial resilience and what role architects can play.
The session concludes with practical guidance on reading Environmental Product Declarations (EPDs), calculating embodied‑carbon impacts based on recycled content, and applying leading standards and certifications to specify low‑carbon aluminum effectively and responsibly.
