Food waste to create 3D printed snacks
One-third of the food produced worldwide is wasted.
For this reason, Elzelinde van Doleweerd graduated at the Eindhoven University of Technology, decided to dedicate her final project - during her Industrial Design degree - to finding ways to make use of this waste.
She started working leftover food with a 3D printer: earlier in the Netherlands, with bread and vegetables, then in China (teamed up with a China-based technology company) with rice and sweet potatoes. The choice depends on the country where we are working. Each state has its majority of wasted food.
Through the Upprinting Food project, the Dutch designer developed a concept that took these leftovers and turned it into new foodstuffs through the use of a 3D food printer: the pastes, made from more then 75 per cent residual food flows, can be used to print different designs such as 2D geometric patterns and 3D shapes such as cups.
Once out the printer, food is totally dehydrated, to make sure that no water remains in it and have a crunchy texture.
Van Doleweerd is trying to make vegan samples by eradicating the butter and egg that is currently included to smooth the paste and make the texture more crunchy. She is also experimenting with several herbs, fruits, and vegetables to create new flavors.
