This study proposes five ecological principles for guiding biomass use towards a circular bioeconomy. Implementing these principles calls for fundamental changes to policies, technologies, organizations, social behavior, and markets.
Natural biomass cycling and avoidance of biomass overharvest are the basis of a sustainable food system. This study proposes five guiding principles for biomass use based on the concepts of ecology and circularity, as well as leverage points for their implementation. A circular, bio-based economy could provide the pathway to a sustainable future. Here we present five ecological principles to guide biomass use towards a circular bioeconomy: safeguarding and regenerating the health of our (agro)ecosystems; avoiding non-essential products and the waste of essential ones; prioritizing biomass streams for basic human needs; utilizing and recycling by-products of (agro)ecosystems; and using renewable energy while minimizing overall energy use. Implementing these principles calls for a transformation of our current economic system, including fundamental changes to policies, technologies, organizations, social behaviour and markets.
