A team of Swedish researchers have produced the world's first model car made out of a light weight alternative to metal. The roof itself is a battery wood-based carbon fiber, the main ingredient to this is lignin. Lignin is the second most abundant natural polymer in the world. These new alternative are renewable as well. One benefit of this is a so-called bioeconomy.
