Carlsberg is testing a new, greener way to drink beer.

The Danish brewing company has launched its new fiber bottle Wednesday — it’s a bottle made with wood fibers on the outside and plant polymers on the inside, according to the company’s website. The entire bottle is both biobased and recyclable, with the exception of the cap.

“The progress made with our new fiber bottle is a testament to Carlsberg’s pioneering spirit, focused on making better products in every sense of the word,” said Simon Boas Hoffmeyer, Carlsberg Group Chief Sustainability Officer, about of the launch.

This isn’t the first time Carlsberg has tried to find more sustainable ways to package its beer. The company was an industry leader in phasing out the plastic rings that typically connect six-packs, replacing them with recyclable glue in 2018.

The stream bottle has been in development since 2015, as Hoffmeyer said in a press release. The company is currently testing 8,000 of the new bottles in the markets of eight Western European countries: Denmark, Sweden, Norway, Finland, UK, Poland, Germany and France.

It consists of two parts. The outer shell is made by the packaging company Paboco. The wood fibers come from forests certified by the Forest Stewardship Council in northern Europe, which means two to three trees are planted for every tree felled, the website says. The inner shell is made of a herbal polyethylene furanoate (PEF) polymer liner, according to The Guardian. It was developed by the renewable chemistry company Avantium.

“Identifying and producing PEF, as a competent functional barrier for beer, has been one of our biggest challenges. a great success!” Carlsberg Group Vice President of Development Stephane Munch said in the press release.

And the innovation of the bottle does not ignore the taste.

“PEF is a very effective barrier between the beer and the fiber shell, able to protect beer quality so consumers can enjoy the same fresh taste of Carlsberg, and insulate beer better than glass or conventional cans to keep beer colder longer,” the site says.

Carlsberg’s ultimate goal is for the fiber bottle to require up to 80% less greenhouse gas emissions than a single-use glass bottle, meaning it will be possible to manufacture five fiber bottles using the same carbon footprint required to make a single-use glass bottle. . Currently, the generation 2.0 fiber bottle already has a better life cycle assessment than a single-use glass bottle. As it stands, repurposed glass bottles remain the most sustainable option, but Carlsberg hopes the new bottle will eventually catch up. The company’s ultimate goal is for the new bottles to add to its glass bottle and can packaging options.

“We’ve been working hard on this project since 2015 and aim to continue setting the industry standard by further improving the bottle’s environmental footprint and product performance,” Hoffmeyer said in the press release. “Collaboration is key, and together with our partners, we are excited to see how research and development of sustainable packaging solutions are now becoming the norm.”

The company also hopes to reach a recyclable cap by 2023, according to The Guardian.

Carlsberg’s sustainability goals also extend to the beer in the bottle. The company has teamed up with barley malt supplier Soufflet to brew beer from barley grown in organic and regenerative agriculture.

“While consumers can still expect the same distinctive Carlsberg taste, the methods used to grow barley are designed to enhance farmland biodiversity, improve soil health and increase natural soil carbon sequestration. compared to conventional farming methods,” the press release said.
