Driving Sustainability with Low Carbon Aluminum

Aluminum is vital to flexible packaging for its protection, recyclability, and adaptability. However, traditional aluminum production carries a high carbon footprint. Constantia Flexibles is leading change with Low Carbon Aluminum — a high-performance solution that significantly cuts CO₂ emissions without sacrificing quality.

“We’re not waiting for standards — we’re setting them” says, Peter Wallach, Segment Lead Processed Meat & Beverages, Peter Wallach, Segment Lead Processed Meat & Beverages and Head of Plant Sales Constantia Teich; Martin Kornfeld, Vice President of R&D at the Competence Center for Aluminum and  Matthias Hofinger, Senior Lead R&D Aluminiu. “Our Low Carbon Aluminum is already used in industries like dairy, pharma, and batteries. It’s not a future concept; it’s happening now”.

What is Low Carbon Aluminum?

Matthias Hofinger explains: it’s aluminum with a much lower CO₂ footprint but the same physical properties. Constantia defines clear limits:

• Max 4 tons CO₂e per ton for primary aluminum

• Max 5.5 tons CO₂e per ton for foilstock

These thresholds are backed by data and third-party verification, ensuring transparency and credibility.

Why it Matters

Martin Kornfeld highlights that while aluminum is an excellent barrier, its carbon cost was a drawback — now solved. Low Carbon Aluminum lets customers reduce emissions without altering processes, since the main change lies in greener energy sources. Peter Wallach adds that Constantia’s expertise keeps them ahead of the curve, expanding their Low Carbon range into new sectors.
