As a UNESCO ASPnet member school, Circular Economy is one of our focus subjects for this school year. Within the framework of European Week for Waste Reduction, we offered 10 kilos of the plastic bottle caps collected at Ralleio Recycling Station to the Circular Economy Laboratory of the Municipality of Piraeus to be test-used as raw material for their cutting-edge 3D printer. We hope that this synergy will be one of the many to follow!
