Carlsberg is testing a beer bottle made of wood fibre

Carlsberg is getting closer to its goal of selling beer in paper bottles, reported CNN.

Last Thursday, the Danish beer company revealed two new recyclable prototypes of the sustainably-sourced wood fibre bottle it hopes to eventually bring to market. One version is lined with a thin film of recycled PET plastic to keep beer from seeping out. The other uses a bio-based lining. The prototypes will be used to test the linings.

For Carlsberg, the innovation is a way to lower its impact on the environment and present consumers with an interesting new option.

Fiber bottles are better for the environment than aluminum or glass because they are sourced in a sustainable way, and because the material has a “very low impact on production process,” explained Myriam Shingleton, vice president of group development for Carlsberg.
