In 2015, 26.5 millions of people where playing sport in France. In many sport, equipment required to play have a short lifecycle. Circular economy or Craddle to Craddle are impossible concepts for this project. Indeed, sport equipments required technicals properties. To get these properties we need to transforme raw materials. This is why we can’t recycle the majority of the sport’s equipments. My idea is to reuse material to create new products. To succeed, I will use the principles of Upcycling. Upcycling is the process of converting old or discarded materials into something useful .
