Circular Biobased Materials

The Circular Biobased Materials Research Group is dedicated to advancing sustainable solutions for materials development, production, and utilization. Our primary focus lies in harnessing the potential of non-utilized biobased resources to create materials that adhere to the principles of circular and bioeconomy. Materials should not only be functional and innovative but also energy efficient, affordable and environmentally responsible. We seek strategies to better convert biobased precursors into materials, while considering the best scenario for their end-of-life. This includes regeneration, reuse, up- / re-cycling, as well as environment reconstitution through biodegradation and biodeterioration.
