By exploring both food waste issues and the problems posed by the raw materials industry, MUSA proposes an alternative biomaterial made from a waste product: banana skin. This skin, the only wasted part of this fruit, is an interesting material because it is accessible, available in large quantities, and in 98% of cases is thrown away. The project therefore fits within an existing research and eco-design approach, by conferring a new value to these skins and giving them a second life. The result of the project is the development of lights made entirely from this biomaterial.
