XCarb® meets BLUESEAL®

PANO® and ArcelorMittal pioneer more sustainable closures for the food industry

PANO® and ArcelorMittal have pioneered a reduced-carbon solution for twist-off closures with PANO®’s BLUESEAL® lug cap which supports decarbonisation within the value chain at ArcelorMittal. It has triggered intensive dialogue and positive collaboration with stakeholders and NGOs about carbon insetting and the challenges of communicating progress on carbon reductions across industry.



PANO® is market leader in the production of PVC-free closures for glass containers in the food and retail industry. Its heritage goes all the way back to 1920, and the business now employs 130 people at its operations in Itzehoe, Germany. It has a production capacity of over 1 billion PVC-free closures per annum, across 80 variants, and has become a lead customer of ArcelorMittal for providing the XCarb® steel certificate solution for PANO®’s innovative BLUESEAL® closures.

PANO®’s BLUESEAL® product offers an industry-first PVC-free seal and lower-carbon steel from ArcelorMittal.

BLUESEAL® is more than just a cap. It is characterised by its industry-first PVC-free seal made from PROVALIN®, a safety-tested thermoplastic elastomer. PANO's PVC-free closures are easily recognisable by their distinctive blue colour (BLUESEAL®). The PROVALIN® seal achieves the EU requirements for packaging in the food and retail industry, taking dangerous plasticisers out of the equation.

In addition to the BLUESEAL® innovation PANO® was determined to develop a reduced-carbon solution for its closures, that was in tune with the company's strong sustainability principles. In 2023 PANO® started working with ArcelorMittal to develop a roadmap towards net zero steel solutions, starting with XCarb® steel certificates.

“Working with customer as PANO® is rewarding in many aspects. Not only were we able to start the journey towards net zero steel already with our XCarb® steel certificate offer. We were also able to work together addressing the complexity of crisp, transparent and correct communication for this new product in the market,” explains Reiner Blaschek, CEO ArcelorMittal Europe – Flat Products.

PANO® has been determined from day one of the initiative to ensure that its offering promoting decarbonisation is understood and accepted by customers and stakeholders as a step in the right direction, and a bridge towards a net zero solution in due course.

For PANO® the main question was how the impact of the XCarb® steel certificates could legitimately be used by PANO®. What initially seemed straightforward turned into a deeper dialogue with its sustainability advisers, B.A.U.M. Consult GmbH, ArcelorMittal and a range of stakeholders and NGOs. With B.A.U.M. Consult GmbH's assistance a clear distinction has been made between offsetting and ArcelorMittal and PANO®’s insetting approach, whereby carbon emissions are not balanced by external offset purchases but by CO2 savings realised within the value chain by dedicated decarbonisation investments at ArcelorMittal plants.

“The XCarb® steel certificates are a key starting point,” says Thomas Stock, CEO of PANO®. “Industry change in our sector needs collaboration between metal packaging companies and their customers, and the XCarb® steel certificates provide a bridging solution on the path to decarbonisation. For us it was crucial to ensure transparent and proper use of XCarb® steel certificates.

This was particularly important because we see our sustainability efforts as a genuine commitment and want to be a reliable partner. Working with ArcelorMittal and B.A.U.M. Consult GmbH, we have now successfully established an acceptable way, recognised by important stakeholders, to use XCarb® steel certificates that meet the regulatory standards of ESRS, the GHG protocol, SBTi alignment, and the still-to-be-implemented Green Claims Directive.”

The whole approach involves transparent communications and engagement with customers and stakeholders that see the XCarb® steel certificate based closures as a practical bridging solution towards physical net zero steel closures in the future.

The PANO® manufacturing line at Itzehoe, Germany, has a capacity of over 1 billion closures per annum.

In February 2025 PANO® and ArcelorMittal participated in a seminar, hosted by the BAUM e.V., the German network for sustainable business, with a wide range of like-minded companies across all sectors, to exchange insights and experience in handling and communication of insetting certificates - a building block on the path to decarbonisation.
