Alcoa expands low-carbon alumina brand

First launched in 2020 for smelter-grade applications (SGA), Eco Source is the world’s only low-carbon alumina brand. Now, it is also being offered in non-metallurgical (NMA) grades, including hydrates and calcined materials. Hydrates are primarily used in municipal water treatment applications; calcined materials are used in the manufacturing of ceramic tiles, glass, and flame retardants.

CO2 intensity well below industrial average

Eco Source, in both SGA and NMA, is sourced from Alcoa’s global refining system, which has an average CO2e intensity below 0.6 tonnes per tonne of alumina produced, which includes Scope 1 & 2 emissions from bauxite mining and alumina refining. Eco Source is part of Alcoa’s Sustana family, which is the most comprehensive in the industry because it is the only brand that includes alumina, primary aluminium and aluminium with recycled content. The other products include:

• Ecolum low-carbon aluminium with less than 4.0t CO2e/t of metal produced, including both direct and indirect emissions from bauxite mining, alumina refining, aluminium smelting and casting. This performance is three times better than the global industry average, says Alcoa, and is offered in a full range of primary products, including foundry, slab, billet, wire rod, high purity and P1020.
• Ecodura aluminium is made with a minimum of 50 % recycled content. It can deliver benefits for building and construction customers in terms of LEED certification points.
