Bicycle frames made of bamboo, kerosene made from algae, trainer soles out of rice husks – there seem to be an infinite number of ideas when it comes to replacing fossil, finite raw materials with renewable, seemingly infinite resources. The proponents of the economic approach summarised as the bioeconomy are not only focusing on using renewable raw materials. Rather, they regard their concept of “biologising the economy” as an opportunity to redesign the global system of production and consumption in a manner guaranteeing a secure sustainable base in every respect. This would be a gain for all – human beings and the environment, business and consumers, North and South. It indeed seems an ambitious project. This edition takes a look at whether the promises made in the context of the bioeconomy really can be kept and, above all, what conditions then have to be fulfilled.
