Shredded post-consumer scrap ready for recycling at Hydro in Clervaux.
Hydro is committed to returning discarded aluminium scrap into the loop for new uses. Our 75R product contains a minimum of 75 percent post-consumer scrap.
Operating the industry’s most advanced sorting technology allows us to offer prime-quality aluminium with the most recycled content in the market. And the higher the level of recycled content – used aluminium – the lower the carbon footprint.
The production process is fully traceable and the product is certified by DNV GL.
Used aluminium from buildings and constructions
An aluminium product becomes post-consumer scrap when it has gone through its life-cycle, when it is ready for disposal, recycling or reuse.
Post-consumer scrap has a high variation in properties. This makes it less expensive to purchase than process scrap, because recycling used metal requires further processing than recycling process/unused scrap.
The used aluminium we purchase for our 75R product is “waste from buildings and constructions” – under the EU waste code 170402. This can be an aluminium window frame obtained from a building that has been demolished.
Our aim is to maximize the benefits of a metal that brings carbon savings in the user phase and that can be infinitely recycled with only five percent of the original energy needed.
In Germany and Luxembourg
Our facilities in Dormagen, Germany, and Clervaux, Luxembourg, work together on the 75R production process. They operate innovative process equipment for sorting, shredding, delaquering/decoating and remelting.
The Dormagen site serves as the “sorter and shredder” facility and is the only supplier of post-consumer scrap for 75R production, which takes place in the remelter in Clervaux.
With its conveying systems, decoating technology and method of submerging the 6060 shredded alloys, the Clervaux plant is a pioneer in aluminium remelting.
Same properties as primary aluminium
The properties of 75R are the same as those of the primary metal, including resistance to corrosion and surface quality. But primary metal cannot match 75R when it comes to carbon footprint.
Seventy-five percent of 75R’s footprint – the used aluminium portion – consists of the scrap logistics and remelting. This is about 0.5 kg CO2 per kg aluminium. The remaining 25 percent comprises aluminium and alloying elements from sources such as primary ingot and process scrap.
In all, the carbon footprint of 75R will be below 2.3 kg CO2 per 1 kg aluminium, due to the use of hydropower-based ingot sources at the Clervaux facility.
And this is world-class.
