A Japanese company is taking vegetable peels, cooking oil and other used foodstuffs and making entirely different products. Concrete is the most widely used construction material in the world, and its key element, cement, is a major polluter of greenhouse emissions. So what if a more sustainable alterative were possible by making cement with food waste, which also would help reduce greenhouse emissions from landfills where that waste would otherwise be thrown away? That’s the idea behind Fabula, a Tokyo-based start-up. Researchers at Fabula created a recipe to make food concrete by drying leftovers and pressing them into a mold (模具) at a high temperature. The company, founded by researchers at the University of Tokyo, began with items commonly thrown away like cabbage and orange peels but found that almost any food item can be use
