Jonas Martens talked about Perpetual Plastic, an installation that transforms plastic waste into 3D printed objects, which eventually becomes plastic waste and can be printed into new objects. Plastic is a valuable (and finite) resource. So how can it happen that less then 10% of the plastics worldwide get recycled? The Perpetual Plastic Project team makes an intervention with an interactive installation, bypassing current waste management systems. The installation gives people an incentive to hand in their waste: a throwaway cup for a ring!
