Students turn discarded chewingum into colourful skateboard wheels
About sixty chewingums are needed for a skateboard. Maybe we all should start chewing for the cause!
Hugo Maupetit and Vivian Fischer from l’Ecole de Design Nantes Atlantique — an international design school in France — have come up with a novel use for discarded chewing gum. for their 3rd year design project, the students created a circular system that collects gum from urban areas and repurposes it into colorful wheels for skateboards.
The system works by installing a number of ‘gum boards’ around cities, which the students have already prototyped in their university city of Nantes. Instead of throwing gum on the sidewalk, people can stick it onto the board, and to encourage them to do so, Maupetit and Fischer devised a lottery concept where people can win discounts on the chewing gum wheels.
Unfortunately, they didn’t get permission from the city of Nantes to install the collection boards on a massive scale. Maybe now that the results are being widely shown, the city of Nantes will decide differently?
The boards will be collected every week and then in a factory, all of the little pieces of gum will be crushed and combined before being turned into a small ball to be machined. Finally, the wheels are machined and stamped with the slogan, ‘VANS x mentos’.
The students installed special collection boards in urban areas of Nantes, France, where passersby could stick their used gum rather than dropping it on the floor.
The gum was then collected every week before the gum was ground together with the collection board itself, which is made from polymethyl methacrylate (PMMA) plastic. The PMMA helps to stabilise the chewing gum as it is melted together and machined into wheels.
“During our test phases we needed between 10 and 30 chewing gums per wheel, depending on the size of the gum and the desired hardness of the wheel,” Maupetit told in an interview with Dezeen.
From the collected gum, the students propose to create three grades of wheel hardness: soft, medium, and hard. The chewing gum wheels would also be available in various sizes to suit different boards.
Chewingum, a guilty pleasure (a little too guilty, though)
Chewing gum, which has existed since antiquity, was originally made from the sap of different trees. But most modern gum consists of a synthetic rubber called polyisobutylene that is also used to create car tyres.
It is estimated that as little as 10 per cent of this gum is disposed of correctly, which means that in the UK alone, local councils have to spend £60 million a year cleaning up the other 90 per cent.
The initiative is envisioned to clean the streets in a sustainable way: ‘our system may have started in nantes, but it is designed to be used all over europe! through this collaboration we can clean the cities and make them better, greener, and more colorful for young people,’ say Maupetit and Fischer.
“By recycling this waste, it becomes a virtuous circle, with the company losing less material and making money from what was originally waste.”
