Carlsberg reveals paper beer bottle prototype

In a bid to develop a sustainable, 100 per cent bio-based and fully recyclable paper bottle for beer, Carlsberg has created two new Green Fibre Bottle research prototypes. Both prototypes are made from sustainably sourced wood fibres that are fully recyclable and feature an inner barrier to allow the bottles to contain beer.

One prototype uses a thin recycled PET polymer film barrier. Meanwhile, the other uses a 100 per cent bio-based PEF polymer film barrier. These prototypes will now be used to test the barrier technology.

“We continue to innovate across all our packaging formats and we are pleased with the progress we’ve made on the Green Fibre Bottle so far,” said Myriam Shingleton, vice president of group development at Carlsberg Group.

Shingleton explained that “while we are not completely there yet, the two prototypes are an important step towards realising our ultimate ambition of bringing this breakthrough to market. Innovation takes time and we will continue to collaborate with leading experts in order to overcome remaining technical challenges, just as we did with our plastic-reducing Snap Pack.”

Carlsberg began work on its Green Fibre Bottle project in 2015. Since then, the brewer has worked with packaging companies EcoXpac and BillerudKorsnäs and post-doctoral researchers from the Technical University of Denmark, supported by Innovation Fund Denmark.

Their combined efforts resulted in the creation of Paboco, a paper bottle company. Paboco has developed a new paper bottle community, which includes Carlsberg, The Coca-Cola Company, The Absolut Company and L’Oréal.

The community’s aim is to develop sustainable packaging. “The work with our partners since 2015 on the Green Fibre Bottle illustrates that this kind of innovation can happen when we work together,” added Shingleton. “We’re delighted that other like-minded companies have now joined us as part of Paboco’s paper bottle community. Partnerships such as these, ones that are united by a desire to create sustainable innovations, are the best way to bring about real change.”
