Allow Inerta aluminium from Rusal is tested in China

Mingtai Aluminium in China is testing Allow Inerta primary aluminium, which Rusal claims is produced with the lowest carbon footprint in the world. 

Allow Inerta aluminium is produced using inert anode technology, which is an advanced development of Rusal.

Lowest carbon footprint in the aluminium industry

“The use of such metal allows reducing the carbon footprint of final products to the lowest possible in the industry, which gives a competitive advantage over other manufacturers, and helps companies to achieve their sustainable development goals, including decarbonization of the supply chain,” says Viktor Mann, technical director of Rusal. “For Rusal, the introduction of this technology makes it possible to completely eliminate emissions of greenhouse gases and polyaromatic hydrocarbons at the electrolysis stage, as well as reduce operating costs by reducing the consumption of anodes. The company is actively working to improve the technology for its implementation on industrial scale and to meet the growing demand from end users,“ he continues.

To be used in battery foil for e-vehicles 

Mingtai Aluminium plans to use Allow Inerta aluminium in the production of foil for its further use in electrical engineering, mainly in batteries for electric vehicles.

“Mingtai Aluminium constantly analyzes its pool of suppliers, taking into account the carbon footprint of raw materials. We strive to choose those suppliers who meet our decarbonization goals. The use of Allow Inerta is the next step towards creating products with minimal environmental impact,” said Yan Shuaijie, production director of Mingtai Group.

Carbon emissions of 0.01 t CO2/t of aluminium produced

The production of Allow Inerta aluminium is characterized by the use of anodes with non-consumable materials – ceramics or metal alloys, which significantly reduce the level of climate gas emissions during the electrolysis process. This solution cuts CO2 emissions (Scope 1&2) to 0.01 t of CO2/t of aluminium produced (the industry average is 12.5 t of CO2/t Al).

Allow Inerta aluminium is produced at the pilot plant at Rusal’s Krasnoyarsk Aluminium Plant (KrAZ). The first batches of metal were shipped in 2021 to companies from the packaging, energy, automotive and electronics industries. More than 4,100 t of metal were produced during pilot tests of the technology.
