COPENHAGEN — Carlsberg Group gave an update on its attempt to create a 100-per-cent bio-based and fully recyclable beer bottle at the recent C40 World Mayors Summit.
The company has unveiled two new research prototypes of its Green Fibre Bottle, which are the first ‘paper bottles’ to contain beer. These developments are a continuation of Carlsberg’s sustainable packaging innovation journey and a key part of its sustainability program, Together Towards ZERO, including its commitment to zero-carbon emissions at its breweries and a 30-per-cent reduction in its full value chain carbon footprint by 2030.
“We continue to innovate across all our packaging formats, and we’re pleased with the progress we’ve made on the Green Fibre Bottle so far. While we’re not completely there yet, the two prototypes are an important step towards realizing our ultimate ambition,” says Myriam Shingleton, vice-president Group Development at Carlsberg Group.
The two new research prototypes are made from sustainably sourced wood fibre, are fully recyclable and have an inner barrier to allow the bottles to contain beer.
One prototype uses a thin recycled PET polymer-film barrier, and the other a 100-per-cent bio-based PEF polymer-film barrier. These prototypes will be used to test the barrier technology as Carlsberg seeks a solution to achieve its ultimate ambition of a 100-per-cent bio-based bottle without polymers.
There is no timetable for the release of its paper beer bottle.
