Known as Cellufoam, the shock-absorbing foam in the helmet is said to be similar to Styrofoam – except it comes from a renewable source, and it's biodegradable

We've seen bike helmets with wooden shells before, and we've also seen foam made from wood pulp. Now, however, Sweden's KTH Royal Institute of Technology has teamed up with Stockholm-based startup Cellutech to combine the two. The result is a helmet made entirely from wood.

Known as Cellufoam, the shock-absorbing foam in the helmet is said to be similar to Styrofoam – except it comes from a renewable source, and it's biodegradable. Like similar products we've covered before, it's made by mixing a foaming agent with cellulose nanofibers derived from forestry industry byproducts. This means that trees don't need to be cut down specifically for foam production.

Even the straps are wood-based, being made from a heavy-duty paper.

Will those paper straps hold the helmet in place during a fall, or result in a nasty paper cut on the ear or neck?

It looks like there is almost enough wood to cook a small meal... If you had 2...............................

This is interesting but you need something like a widely adopted cardboard house to do much.

It would make a nice bowl to eat your lunch out of then dry it off and wear it home, since it is wood and paper it would be micro wave safe......I like it!! I want 2-3 of them.........LOL :-)
