Aluminium UBCs supply over 70% of can scrap globally, but metallurgy determines circularity, Innoval’s COP30 factsheet shows
UBCs Dominate Global Can Scrap Supply
Aluminium used beverage containers (UBCs) contribute over 70% of the total can scrap generated worldwide. This makes beverage cans the most significant source of recyclable aluminium in the packaging sector and a critical pillar of global circular economy strategies discussed around COP30.
Metallurgy Is the Key to Circularity
Innoval’s COP30 factsheet highlights that true circularity depends on metallurgical control, not just high collection rates. Can bodies and ends use different aluminium alloys with strict chemical limits, and improper alloy balance during recycling can prevent scrap from being reused in new cans.
Closed-Loop Recycling Is Technically Complex
Although aluminium is infinitely recyclable in theory, keeping can material in a closed loop requires advanced sorting, alloy management, and melt practices. Without these controls, recycled aluminium may be downcycled into lower-value applications instead of returning to can production.
Regional Gaps Affect Recycling Outcomes
Recycling performance varies widely by region. Some markets collect large volumes of UBCs but lack the metallurgical capability to maintain alloy quality, while others struggle with collection and sorting infrastructure. These disparities limit global circularity gains.
Future Targets Depend on Metal Science
Ambitious industry goals for higher recycled content and near-total can recycling will only be achieved if metallurgy is treated as a strategic priority. Innoval’s message is clear: aluminium cans already offer strong circular potential, but long-term sustainability depends on mastering the underlying metal science.
