Feasibility Concept of Reducing Food Waste in 3D Printer

A young Dutch entrepreneur is reducing food waste by printing food in 3D. Nearly a third of the world's food production is wasted, but people still feel hungry. It is the barriers to food preservation and freshness that cause a lot of waste. Basically, food deteriorates during transportation or on shelves waiting to be purchased or used. Elzelinde van Doleweed recently graduated from Eindhoven University with a degree in industrial design, but she also studied food technology; for her final project, she could integrate the two fields by processing food, otherwise the food would be thrown into a more easily preserved 3D printing format.



Her project was so popular that she started Upprinting Food. Various foods are wasted at different speeds in different regions, so Van Doleweed starts at home. "In the Netherlands, we waste a lot of bread," commented Van Doleweed. "When bread is old and dry, we don't like it anymore. So I started making paste from old bread."



"I cook vegetables and fruit peels, dry bread or cook rice," she explained. "These ingredients are mashed, mixed, ground and screened. Then you can print out a smooth paste and bake it." By making food pastes and storing them in sealed containers, food can be protected from exposure to air, which is a factor of corruption. Each 3D print is then baked to remove moisture, which is another cause of corruption. "This prevents bacterial activity," Van Doleweed said. "In this way, food can be eaten safely, and we can keep it for a long time."



Most of her responsibilities include consulting restaurant managers and chefs to make sure that food waste in their kitchens can be reprocessed. "They are made of more than 75% of the remaining food flow and some additional ingredients into smooth paste and some spices for seasoning. I made samples of sweetness and saltiness with different herbs and spices, "the report said they were Biscuits - like.

To expand the product range, Van Doleweed works with Beijing-based 3D Food Company. Van Doleweerd said: "In China, people eat a lot of rice, but they also waste a lot of rice. So I created a printable paste of food, rice instead of bread, vegetables and fruits.



In October 2018, Elzelinde had the opportunity to present her recipes at Beijing Design Week, for which she developed two sustainable food concepts in 3D printing. Other participants and projects can be seen on her Upprinting Food website.

There is no doubt that 3D printing has affected many industries. Supplementary manufacturing not only provides opportunities for everyone to create, but also solves one of the biggest problems in the world, namely food waste. Restaurants have begun to add 3D printers to their menus. Although 3D printers still need to improve their production time, they are promising and innovative.
