GPBO, together with Captain Fanplastic and RanMarine, offers a special program for primary schools: the #NoTrashButTreasure Challenge. We want to inspire and help students to combat plastic pollution and make a positive impact in their own environment. We challenge them to do a clean-up/treasure hunt around the school and in the port of Lauwersoog, focusing on theory, creativity and gamification. The program has finished, registration is not possible anymore (July 2024).
