Carlsberg has revealed two new protypes of the “world’s first” paper beer bottle as it continues to work towards a Green Fibre Bottle.
Made from sustainably sourced wood fibres, it is both 100% bio-based and fully recyclable, the brewer said.
One prototype uses a thin recycled PET polymer film barrier, and the other a 100% bio-based PEF polymer film barrier. These prototypes will be used to test the barrier technology as Carlsberg seeks a solution to achieving its ultimate ambition of a 100% bio-based bottle without polymers.
Myriam Shingleton, Vice President Group Development at Carlsberg Group, said: “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.
“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.”
Carlsberg kicked off the project to develop a bottle made from sustainably sourced wood fibres in 2015 alongside innovation experts EcoXpac, packaging company BillerudKorsnäs and post-doctoral researchers from the Technical University of Denmark, supported by Innovation Fund Denmark.
The combined efforts have resulted in the emergence of Paboco, the paper bottle company – a joint venture between BillerudKorsnäs and bottle manufacturing specialist ALPLA.
Carlsberg will now be joined by The Coca-Cola Company, The Absolut Company and L’Oréal.
