Saturday 23 and Sunday 24, ILS students present their concepts at Festival Mundial. With their sustainable ‘bitterballs’, startup De Ballenmeisjes is responding to the waste of food in our society. ‘Our target group is the benevolent consumer who wants to consume sustainably, but finds the threshold too high', explains Anke van Ettinger. The young entrepreneurs came up with the idea of a bitterball containing residual products. To achieve this, they worked together with various restaurants in Tilburg. A number of students who participated in the Fast Fashion Challenge also present their concepts to reduce waste in the fashion industry. Not only ILS students will present their concepts during Festival Mundial, students of other programmes also focus on sustainability.
