Any American parent is familiar with fruit leather, that tasty roll-up snack that fits nicely into a lunch box and that kids love to unwrap.

Who ever would have thought it could be anything other than a snack? A Dutch designer, that’s who.

What began as a school assignment at Willem de Kooning Academy in Rotterdam for students to set up a flash retail event has turned into Fruitleather Rotterdam. When a group of six students started working on the assignment, they decided to also tackle the widespread problem of food waste.

They began taking leftover food off vendors’ hands, started used the fruit — mangos, oranges, nectarines, apples and more — to manufacture material using a proprietary process. The end product is a maleable leather that can be used for making accessories like purses, bags, wallets and more.
