Every year they end up in the garbage almost a billion tons of food. A number that weighs on the environment and everyone’s pockets. In France, for example, in 2021 they accumulated 8.8 million tons of food wasteabout 129 kg per personaccording to the Ministry of Ecological Transition. While we continue to throw away peels, coffee grounds and eggshells, two engineers from MIT they decided to reborn them in a completely new form: 3D printed everyday objects.
Is called FOODres.AI Printer and it is a capable 3D printer transform food waste into household utensils such as cups, bowls and coasters. All thanks to a system based on artificial intelligence that recognizes waste and transforms it into one bioplastic pulp ready for printing. Its creators, Biru Cao and Yiqing Wangexplain that the goal is not only to reduce organic waste, but turn it into a useful resource.
How it works
The machine works like this: they fit in inedible food wastesuch as banana peels, coffee grounds or eggshells. Intelligent software analyzes them and calculates the perfect recipe to create one printable bioplastic pasta. Then the most fascinating part comes into play: a system of heating extrusion which shapes the material layer by layergiving shape to the chosen object.
The whole process is fully automatedso even those who have never touched a 3D printer can use it. The dedicated app allows you to select preset templates or upload your own design. The artificial intelligence also recognizes the available materials and makes suggestions what type of object can be made based on the characteristics of the mixture.
A sustainable, creative and award-winning idea
According to MIT researchers, this technology is meant to make people protagonists of environmental changestarting from their kitchens:
It’s not just about reducing waste, but about making food recycling a creative, accessible and concrete gesture.
The printer can be used in homes, schools or community centresreducing the use of petroleum-derived plastic and the methane emissions linked to the decomposition of organic waste.
In addition, the low cost and ease of use pave the way for a new form of domestic circular economywhere nothing really goes to waste.
It is no coincidence that the FOODres.AI Printer has already won two international awards, such asiF Design Award 2025 and the Platinum A’ Design Award 2025. A success that confirms how much technology, sustainability and design can collaborate to give a second life to what we usually consider “rubbish”.
