US-based aluminium producer Alcoa announced on Tuesday November 9 its adoption of a three-stage "technology roadmap" intended to assist in the decarbonization of upstream aluminium supply and to help achieve the target of net-zero carbon emissions by 2050.
The roadmap has three key elements. These are the decarbonization of the alumina refining process, new processes to enhance the use of post-consumer scrap, and the use of Elysis technology that eliminates greenhouse gases from the smelting process."Our 'Refinery of the Future' design and the Elysis zero-carbon smelting technology not only aim to reduce costs and improve efficiency in aluminium production, but target...
