The need to shift towards sustainable systems of production and consumption to respond to societal challenges such as climate change, natural resource scarcity, food insecurity, fossil fuel dependence and environmental pollution is undisputed. However, since the drivers, constraints, opportunities and risks of different regions and countries are very different, there are always controversies and differences regarding the strategies and policies for developing sustainable systems. This applies not only in the field of bioeconomy but also in that of biologically produced products such as biopolymers. Here, the development of new products, methods or tools in research can always provide new approaches and new impulses for discussion. Be curious!
