Add cabbage leaves, orange peels, onions, bananas and a few slices of pumpkin to get... cement. That's right, researchers from the University of Tokyo in Japan have developed a technique through which it is possible to produce cement from food waste. Besides being used in construction, the innovative initiative is edible as well. You can make boiled cement into a delicious meal by adjusting flavors, adding seasonings, and breaking it into pieces.
Yuya Sakai, the professor responsible for the study, is an engineer specializing in concrete and recycling. In previous research, he developed a technique for mixing recycled concrete powder and wood waste, generating a more resistant material through hot compression. It was during these trials that the idea arose to test other waste materials similarly, including – why not – vegetables and fruits.
