VTT and ISKU have created a novel biocomposite chair from cellulose

Merging cutting-edge technology with sustainable design, VTT Technical Research Centre of Finland and ISKU have joined forces to create a new kind of chair that showcases the potential of biocomposite materials. Crafted from a cellulose-plastic compound that uses natural annual fibres, polypropylene and wood pulp from Finnish forests as raw materials. The new demo chair can be seen and experienced at the Pulp & Beyond 2024 Exhibition on April 10th-11th 2024 at the Helsinki Expo and Convention Centre.

“The biocomposite material was produced by VTT using foam forming technology, which was originally developed for papermaking. The process allows for high-volume and cost-efficient production and provides nearly limitless options for product customisation. Unlike conventional methods, we maintain the fibre properties and can get full reinforcing potential,” explains Miika Nikinmaa, Biomaterial Solutions Lead at VTT.

This chair not only showcases the potential of biocomposite materials but also embodies ISKU’s commitment to innovation. Mikko Porter, Head of Lean Six Sigma at ISKU, emphasizes, “Our aim isn’t merely to replicate existing products using new materials, but to pioneer innovative solutions that address unique customer needs previously unmet on the market.”

With exceptional mechanical properties and the ability to be 3D molded into intricate shapes, the biocomposite material offers versatility and sustainability. Moreover, it can be recycled at the end of its lifecycle, reducing environmental impact.

The biocomposite chair is a revolutionary product for the furniture industry. “VTT will work with partners to advance the technology and explore ways to bring this exciting technology to market in the future. The material is expected to become available to consumers in the medium to long term,” Nikinmaa says.

Collaboratively developed within the HiPer project, funded by Business Finland, that involved VTT, ISKU, CH Polymers, Koskisen, Metsä Fibre, NMC Cellfoam, Paptic Ltd, Sulzer, Valmet and Volar Plastic, this chair represents a significant step towards a more sustainable future.
