The glass beer bottle might undergo an eco-friendly transformation if a new initiative by Carlsberg proves to be successful.

Per Beverage Daily, the Danish brewer is piloting a program across Western Europe for its new Fibre Bottle, a bio-based vessel for its pilsner. The outside of the bottle is made from sustainably-sourced wood fiber, while the interior is a plant-based PEF polymer lining that is biodegradable.

With these new bottles, Carlsberg hopes to produce 80% fewer emissions than the current production of single-use glass bottles; as well, the company claims the outer shell can actually do a better job at keeping your beer colder.

Besides the new bottle, Carlsberg is also brewing its beer with barley that has been cultivated using fully organic and regenerative agricultural practices. And while the current metal bottle cap is recyclable, the brewer is also developing fiber-based bottle caps.

The initial trial will see 8,000 Fibre Bottles being sampled in Denmark, Sweden, Norway, Finland, United Kingdom, Poland, Germany and France, primarily at festival, flagship events and product samplings.

This isn’t the first glass bottle alternative we’ve noticed recently: Absolut debuted a prototype for a paper bottle a few years back, with hopes of introducing it to consumers by 2023.
