Bicycle Helmet from the Forest

Print Print this Article | Send to Colleague

Cellutech, Sweden, has developed a bicycle helmet entirely based on materials from the forest. It is showcased today and is the first product realized from the inspirational project Ekoportal2035, created by Skogsindustrierna.

The helmet is a prototype designed and constructed by the designer Rasmus Malbert. Cellulose materials with different expressions were used in the design process. The helmet has an outer shell of wood veneer and straps made of durable paper. The cushioning inside consists of Cellutech’s cellulose foam, Cellufoam™.

Cellufoam is a new and unique material made of nanocellulose produced from wood pulp and is therefore both renewable and biodegradable. The properties of Cellufoam are suitable for use in lightweight construction, packaging materials, absorbent products, etc. The idea of the foam comes from a research group within the Wallenberg Wood Science Center (WWSC) and has been further developed by Cellutech.

"The collaboration with Cellutech makes it possible to commercialize the new materials we develop within WWSC and bring them closer to the market," said Lars Wågberg, professor at the Royal Institute of Technology.

The bicycle helmet is the first example of how Cellufoam can be used. Work is now in progress to find more suitable applications. There is currently an increasing need for renewable and biodegradable foam materials that can replace plastic foams.

"We have shown that with new innovations and good cooperation with university research, it is possible to use forest raw materials to produce foam materials. That is something we are very proud of," said Åsa Ek, development manager at Cellutech.

"I think there is an incredibly strong potential in this material, we are just at the beginning of an exciting trend where more and more petroleum-based materials are replaced with renewable alternatives," noted Malbert.

Cellutech was founded in 2012 and has developed a number of technologies within renewable materials. The company cooperates with the Wallenberg Wood Science Center (WWSC), a Swedish research center focused on new materials from the forest. The company is owned by some 20 researchers at WWSC, Stora Enso, FAM, Bergvik Skog, SweTree Technologies, KTH Holding, and Chalmers Capital.
