This book highlights the efforts made to realize the concept of ‘Circular Bioeconomy’. It has twelve (12) chapters, focussed on five (5) sections, namely Biomaterials, Environment, Energy, Pharmaceutical and Enzyme Technology. It portrays research, linking ‘Circular Bioeconomy’ to the United Nation’s Sustainable Development Goals (SDGs). The concept of ‘Circular Economy’, including ‘Circular Bioeconomy’, aims to shift the current, essentially linear economic system to a more sustainable one. Accordingly, the key goal of a ‘Circular Economy’ is to slow, narrow and close material resource loops, built on the foundation of renewable energy and non-toxic materials. Further, a sustainable ‘Bioeconomy’ goes beyond simply switching fossil resources with renewable, biological resources. It requires low-carbon energy inputs, sustainable supply chains and promising disruptive conversion technologies for the sustainable transformation of renewable bioresources to high-value bio-based products, materials and fuels. Thus, a sustainable ‘Circular Bioeconomy’ transition will necessitate a set of consistent metrics that fit all products and industries.
