A presentation for primary schools about waste, its consequences and the things we can do with waste by recycling it. Our focus is on plastics, so by making a boat from recycled plastics, we showed the kids the value of plastic waste: it is still a good resource for new products. They wrote a message or wish about a cleaner environment, or even a new product idea for recycled plastic, on these boats. We hung the 1.000 boats on the Erasmus bridge! A real eyecatcher with a clear message on awareness of (plastic) waste.
