The two research prototypes for its Green Fibre Bottle are made from sustainably-sourced wood fibre, and have an inner barrier to allow them to contain beer, the firm announced today.
Carlsberg said in a press release that it was close to selling beer in paper bottles, in part to the partnership.
Two prototypes are in the works for their Green Fiber Bottle: one with a thin layer of a recyclable polyethylene terephthalate (PET) plastic in the interior, and the other using instead a polyethylene furanoate (PEF) polymer film that is 100-percent biobased, meaning it's made from natural, biodegradable sources.
The company's ambition is to eventually create a 100 per cent bio-based bottle without polymers, an aim which forms part of Carlsberg's wider sustainability goals to achieve zero carbon emissions at its breweries and a 30 per cent cut in its full value chain CO2 footprint by 2030 against a 2015 baseline.
Myriam Shingleton, vice president of group development for Carlsberg, said that fiber bottles were more environmentally friendly than aluminum or glass because the material has 'very low impact on production process'.
"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 [plastic-free beer can packaging]".
These combined efforts have resulted in the emergence of paper bottle company Paboco - a joint venture between BillerudKorsnäs and bottle manufacturer Alpla.
Drinking beer might not be the best for your health, but Carlsberg is out to prove it can be better for the environment.
Carlsberg will now be joined by The Coca-Cola Company, The Absolut Company and L'Oréal in a paper bottle community - launched today by Paboco®.
Shingleton continued: "The work with our partners since 2015 on the Green Fibre Bottle illustrates that this kind of innovation can happen when we work together".
"We're driven by our constant pursuit of better, to create more sustainable packaging solutions that help people to live more sustainable lives".
Gittan Schiöld, interim CEO of Paboco® said: "It is all about the team!"
