Alcoa Corp. unveiled a technology roadmap to support the company’s vision to reinvent the aluminum industry for a sustainable future. The technologies in Alcoa’s roadmap, including a proprietary post-consumer scrap-recycling process, have the potential to decarbonize a significant portion of the upstream aluminum supply chain. The roadmap includes three key programs: the Refinery of the Future, the ASTRAEA metal purification process and ELYSIS joint-venture technology.
The Refinery of the Future aims to both reduce the capital cost of developing a refinery and enable decarbonization of the alumina refining process. Alcoa would use a combination of processes and technologies that are under development, including mechanical vapor recompression and electric calcination to develop this future-focused design.
