At the Krasnoyarsk Aluminum Plant, primary aluminum from the electrolysis shop was mixed with pre-prepared and molten scrap and poured into flat ingots in the foundry. This is an atypical technological process for a producer of primary aluminum alloys, which requires an innovative approach, RUSAL reports. Scrap has a near-zero carbon footprint and its involvement makes it possible to reduce the level of emissions of finished products produced from it.
The new product combines decarbonization tools such as scrap and aluminum ALLOW INERTA, produced using inert anode technology. For KRAZ products, this combination reduces the carbon footprint of the final product by more than two times compared to the traditional technology of the enterprise.
The cast flat ingots will be processed into a can tape and then into an aluminum can.
In 2023, KrAZ already used scrap in the production of primary aluminum casting alloys for the production of car rims, and in 2024, for the first time, it processed a batch of 60 tons of aluminum can scrap. Electricity from renewable sources is used to produce such products.
