Abstract
The Green Aluminium phenomena although recent in notion, has been materializing over the last century with the first dedicated hydroelectric power stations for aluminium production being commissioned early in the twentieth century. With the EU emission target strategy in full swing, individual producers setting their own values and speculation on the formation of a newly indexed metal, producers, technology suppliers, and regulators are trying to common ground to materialize a niche portion of aluminium production to meet the emission-related targets. The carbon dioxide makeup of aluminium production is dominated by the electrolytic reaction followed by the anode consumption and then the Bayer process. The industry has spent significant efforts in decarbonizing the former two, the latter still needing strong conceptual development. This paper intends to explain the conceptual contribution towards Green Aluminium from the perspective of a Bayer process technology supplier.
