A house like that of Hansel and Gretel? Scientists manage to turn food into cement and concrete
Have you ever wanted to get into a grocery store like Hansel and Gretel?
Well, the idea may not be as far-fetched as you think!
Scientists in Japan have discovered a way to turn food waste into cement, which can be used to build homes in the future.
Experts hope that this can help address the problems of food waste but also global warming.
Researchers at the University of Tokyo have successfully realized a concrete-like building material from leftover food. It is the first time that cement has been made entirely from food waste.
They tasted a variety of foods, including banana peel, onions, orange peel, tea leaves, coffee grounds, squash, and seaweed.
The scientists pulverized the foods and then pressed them hot into a mold.
Although the materials turned out differently in quality, the team said it was surprised to find that most of them had a strength that was greater than that of concrete.
In fact, cabbage turned out to be among the best vegetables, producing a material that was almost four times stronger than cement!
Scientists say that since cement made from food is biodegradable and can be buried when it is no longer needed.
