The European Researchers' Night, a science festival with mini-lectures, experiments, music and dance, returns to Groningen on Friday 27 September. In the run-up to the event, participating researchers give a sneak preview. Today, UG scientists Kim Poldner and Ellen van der Werff talk about ‘circular textiles’. Although the rise of ‘ultra-fast fashion’ is disturbing, the two researchers also see great opportunities, for example in the field of digital fashion.
