Ball has signed an agreement with Rusal, a member of the EN+ Group, to supply low-carbon aluminum for the production of beverage cans and other containers, which will be produced by Rusal using innovative inert anode technology.
Aluminum is a circular economy material because of its high value and the fact that it can be recycled endlessly without loss of quality," said Jason Galley, Ball's head of sustainability, innovation and business development. Few people realize that 75 percent of the aluminum produced in human history is still in the use phase. As the demand for aluminum packaging continues to grow everywhere, we need to focus on mitigating any environmental, social and governance (ESG) impacts associated with that supply. That's why we work closely with industry suppliers such as En+ Metals to achieve responsible sourcing."
The aluminum smelting process is known to be carbon intensive. One way to improve the sustainability of primary aluminum production is to replace standard carbon anodes with inert, non-consumable materials (called inert anodes), which will actually produce carbon in the process (although separate attention needs to be paid to the carbon intensity generated by power generation).
Rusal has been successful in producing primary aluminum using its proprietary inert anode technology, which has been implemented as an industrial pilot line at smelters owned by Rusal. Rusal says this technology is capable of producing an industry-low carbon footprint: less than 0.01 t CO2/ton aluminum (based on Scope 1, Scope 2 - direct and indirect energy emissions) and producing aluminum with a purity higher than 99%. Rusal is working to scale up this technology to commercial scale.
Steve Hodgson, Director of Sales and Marketing at Rusal, said: "Our partnership with Ball represents the future possibilities of a sustainable aluminum product that is at our current low carbon level through all greenhouse gas emissions from the production process. We are particularly pleased to see Ball's own sustainability platform and to help meet subsequent human needs."
Both Ball and Rusal are members of the Aluminum Stewardship Initiative (ASI), a multi-stakeholder organization dedicated to enhancing the sustainability of the global aluminum chain value chain by promoting responsible production, sourcing and corporate compliance governance of aluminum.
