Hydro brands Technal and Wicona today announced they have become the first aluminium building system companies to manufacture door, window and curtain walling profiles from 100% recycled aluminium, using the new Hydro Circal 100R.

The material is produced from 100% post-consumer aluminium, making it possible to specify profiles with a near-zero carbon footprint (0.5kg of CO2e/kg of aluminium on average), which the company says is the lowest in the world. Hydro says it is the only producer in the world able to supply this recycled aluminium with a near-zero carbon footprint.

The group has established its own recycling channel. Its Dormagen plant in Germany harvests aluminium from end-of-life windows and façades, separates any non-metallic materials, before the aluminium is shredded into small chips. These are sent to Hydro’s plant in Clervaux, Luxembourg where they are manufactured into low-carbon billets of Hydro Circal 100R and its existing 75R.

Technology allows the right alloy to be identified, which supports the production of this construction-quality 100% recycled aluminium without the addition of any primary aluminium.

The Technal extrusion plant in Toulouse, France and the Wicona extrusion plant in Bellenberg, Germany are in the process of delivering their first projects in France and Germany respectively. For these two projects, a total of 130 tons of Hydro Circal 100R aluminium profiles has been manufactured. Providing a combined carbon footprint of 65 tons, this is a reduction of 800 tons compared to the carbon footprint of standard aluminium produced in Europe.
