Avantium, innovator in renewable chemistry, is working with The Bottle Collective on a new type of sustainable fiber bottle. This collaboration should lead to a widely applicable, fully plant-based packaging solution that can eventually replace plastic bottles.
The Bottle Collective is an initiative of PA Consulting and Swedish technology company PulPac, known for its patented Dry Molded Fiber technology. This technique uses dry cellulose fibers to be molded into packaging under high pressure and temperature — without the use of water. The result is packaging with a significantly lower carbon footprint than conventional alternatives.
Biobased barrier layer
Within this project, Avantium is supplying its fully plant-based and recyclable polymer PEF (polyethylene furanoate), which serves as a barrier layer in the bottle. PEF prevents oxygen and carbon dioxide from escaping and thus extends the shelf life of beverages without loss of taste. Thanks to the high mechanical strength of PEF, thinner packaging can also be produced, which saves material and waste.
Broad cooperation
In addition to Avantium, companies such as Logoplaste, Diageo, Opella Healthcare (Sanofi) and Haleon are also involved in The Bottle Collective. These companies represent various links in the packaging chain and jointly contribute to the scaling up of this innovation.
The first prototypes of the fiber bottles have now been developed. The partners are now focusing on further optimization and industrialization of the production process, with the aim of making these sustainable bottles available worldwide.
Sustainable alternative to disposable plastic
By using biobased materials and innovative design techniques, The Bottle Collective is taking an important step towards circular packaging solutions. avantium This collaboration fits in seamlessly with the mission to develop fossil-free and circular materials for a future-proof economy.
