Aluminium is recyclable; that is not the same as recycled
Remelting aluminium takes about five per cent of the energy of making it from ore. What matters is how much of what you are buying actually came from remelt.
Recyclability is a property of the metal, and every extruder in the world can claim it. Recycled content is a property of a particular billet lot, and it moves from lot to lot depending on what scrap was available that month. The two get used interchangeably in marketing, and a specification that asks for the first has asked for nothing.
Billet cast at Yen Bai ran at 61 per cent recycled content across 2025, most of it post-industrial: our own extrusion scrap, offcuts returned from fabricators, and reclaimed sections from demolition where the alloy can be verified. Post-industrial is the easy half. Post-consumer is the hard half, because the alloy has to be verified before it can go back into a structural section — which is why we quote recycled content per order, against the mill certificate for that billet, rather than leaving you with the group average.
The two anodising lines at Quy Nhon discharge to an on-site treatment plant with closed-loop rinse recovery. Pretreatment on the powder lines moved from chromate to chrome-free zirconium during 2025, which removes a hazardous waste stream rather than treating it.
Rooftop solar across the five plants covers about 18 per cent of electrical demand. It will not go much higher without storage, because extrusion load is heaviest on night shifts. We publish the numbers annually and we publish the ones that did not improve: Scope 3 remains the weak part of the picture, dominated by primary billet bought in when remelt supply is short.
