Safe motorcycle helmets -- made of carrot fibers?

All over the world, research is being conducted into biodegradable and recyclable synthetics. However, fiber-reinforced components remain problematic - if glass or carbon fibers are used. Within the scope of an EU research project, the Scottish company Cellucomp Limited has now developed a method to obtain nanofibers from carrot waste. These fibers would be both cost-effective and biodegradable. However, is the method, which works in the lab, also marketable on a large scale?
