The Gum is Collected & Melted With Plastic
To collect the discarded gum, Hugo and Vivian install special collection boards in the busiest areas of Nantes, France. As you can see, the whiteboard has a little half-face design, so passerby’s can decorate the ‘hair’ with colourful gum.
Over the week, passerby’s stick their chewing gum onto the boards. At the end of every week, Hugo and Vivian collect the gum boards.
Once the gum is cleaned and shredded, it gets melted down with the whiteboards that they were placed on. The boards are made from polymethyl methacrylate (PMMA) plastic, so they help to stabilise the gum and create a new substance that can be fashioned into a sturdy wheel! Natural dyes are added to give the wheels the groovy, swirly patterns that you see in the images.
