Norsk Hydro's CIRCAL 75R aluminum uses at least 75% post-consumer recycled scrap, cutting embedded carbon compared to primary metal. It targets architects and developers who need verifiable low-carbon materials for building facades, windows, and curtain walls. The product performs like standard aluminum but carries a smaller climate footprint, helping projects meet green certification targets. The recycled content comes from end-of-life building components like old windows and doors, remelted and returned to construction supply chains. Availability is strongest in Europe, especially Norway, Germany, the UK, and the Netherlands. For investors, CIRCAL 75R shows how Norsk Hydro combines recycling with premium products to maintain margins while decarbonizing. The main limitation is scrap supply quality and volume, which can affect labeling and project eligibility.
