Contribute to the sustainability of society by designing a bio-based product or process. This was the task set for pioneering student teams participating in the third edition of the European Biobased Student Innovation Challenge 2021. The five finalists presented their innovative projects to a jury consisting of leading experts from across the bio-based sector. The combined votes from the expert jury and an audience of bio-based industry representatives decided which of the top five teams was the overall winner of BioSYNERGISE 2021, an event organised by the Bio-based Industries Consortium (BIC). Team WaterSkins from the Netherlands rose to the top with their innovative idea to harness wastewater to produce a leather-like material.
