The alloy standardisation initiative will explore recycling-friendly alloy options for can ends, which, if successful, will improve the overall recycled content potential for the whole can. How will this collaborative initiative between Constellium, Elval, Novelis and Speira drive innovation in sustainable packaging? In the past, manufacturers of flat-rolled aluminium worked together with the can industry to improve the can's carbon footprint through weight reduction and high recycled content for the can body alloy. For further improvements, this sustainability standardisation agreement is a major milestone on the way towards cans being made from up to 100 percent recycled aluminium. Maximising the recycled content levels of the aluminium beverage can substantially lower carbon emissions and help achieve sustainability goals. Any proposed change will take full advantage of the fact that recycled aluminium saves 95 percent of the energy needed to produce primary aluminium.
