Did we get you? As much as we would love to recycle cardboard into beer, it really wouldn't work. If you do come up with a recipe, let us know - we have lots of recycled cardboard you can use!!
We were however impressed to hear that Danish beer giant Carlsberg has recently unveiled designs for what it claims is the world's first paper beer bottle, made with sustainable and recyclable wood fibres.
The brewer has revealed two prototypes for its 'green fibre' bottle. Both are made from sustainably sourced wood fibres and have an “inner barrier” allowing the bottle to hold beer. One uses a thin recycled PET polymer film barrier, while the other has a bio-based PEF polymer film barrier.
Carlsberg initially launched plans for the project back in 2015, working alongside EcoXpac, BillerudKorsnäs and post-doctoral researchers from the Technical University of Denmark. This collaboration has resulted in the creation of paper bottle company Paboco, a joint venture between BillerudKorsnäs and bottle manufacturing specialist ALPLA.
Companies also working with Paboco include Absolut, Coca-Cola and L’Oréal. Last year, Carlsberg invested in a number of other sustainable solutions, including recycled shrink film, greener label ink and Snap Pack, which replaces the plastic packaging around its six-pack cans.
