Dutch designer against food waste

These 3D-printed snacks are made from leftover food

Around a third of the food we produce around the world goes to waste. It is sad but true. However, one tech-minded foodie has created eye-catching 3D printed concoctions from residual food.

Dutch designer Elzelinde van Doleweerd’s Upprinting Food project aims to trim back on food waste by taking unsold or commonly overabundant food like fruit, vegetables, bread and rice and using the latest tech to put a new spin on things.

By creating printable pastes from the foods, she’s able to form attractive shapes that are then baked, dehydrated and arranged to form attractive meals with a longer shelf life. Ripe bananas and knobbly carrots that aren’t pretty enough to be sold are prime candidates for the 3D Food Company’s advanced printer.

“I boil the vegetables and fruit peels, dry the bread or use the boiled rice. The ingredients are mashed, mixed together, ground and sieved. A smooth paste can be printed and baked afterwards.”

The dehydration technique is used “so no bacterial activity can take place,” she says. “This way the food is safe to eat and we can save it for a very long period.”
