The fibre bottle features an outer shell produced by packaging company Paboco, which is made of sustainably sourced wood fibre.
The shell’s insulative properties are designed to keep beer cold for longer periods compared with regular cans and glass bottles.
In addition, the bottle features plant-based polyethylene furanoate (PEF) polymer lining developed by renewable chemistry expert and Carlsberg partner Avantium.
Made from natural raw materials, the PEF is claimed to have highly effective barrier properties and can be recycled by plastic recycling systems, as well as degrade into nature.
The pilot scheme will involve 8,000 fibre bottles being sampled in Denmark, Sweden, Norway, Finland, the UK, Poland, Germany and France.

The bottles will be provided to local consumers, customers and other stakeholders via festivals, flagship events and targeted product samplings.
Carlsberg group sustainability director Simon Boas Hoffmeyer said: “The progress made with our new Fibre Bottle is testament to Carlsberg’s pioneering spirit, with a focus on making better products in every sense of the word.
“We’ve been working hard on this project since 2015, and aim to continue to set the industry standard by further improving the bottle’s environmental footprint and product performance.
“Collaboration is key and, together with our partners, we’re excited to see how research and development into sustainable packaging solutions is now becoming the norm.”
The trial is claimed to be Carlsberg’s largest to date and aims to expedite the company’s efforts to commercialise the beer bottle.
Carlsberg said that it will work with Paboco and partners in the paper bottle industry to develop fibre-based bottle caps, with a generic solution expected to be launched next year.
At the same time, the brewer will continue its partnership with Avantium and Paboco to develop a 3.0 solution suitable for primary beer packaging.
