It is a large-scale project that should make it possible to decarbonize aluminum production in France. "Aluminium is very useful in the context of the ecological transition because it makes it possible to lighten means of transport, especially electric vehicles, and is also infinitely recyclable," explains Sébastien Gauguier, President of the aluminium division at Fives. But we need to manage to decarbonise primary aluminium production", even if French production is among the least carbon-intensive in the world, thanks to a very low-carbon electricity mix. All the former Pechiney sites (Aluminium Dunkerque, Germany's Trimet, and Rio Tinto) are working with the Fives engineering group to achieve this. This carbon is emitted when the anode burns during the electrolysis process used to make this metal. This is what we call fatal carbon, an astonishing expression but one that makes sense. It is a question of CO2 emissions that are impossible to eliminate because directly...
