University of Tokyo researchers in Japan have created a new technology that uses food waste in a surprising way.Student Kota Machida and Professor Yuya Sakai say the operation can turn food waste into a strong but bendable material like cement.They say it is four times stronger than regular concrete, and is sustainable.And, you can eat it, the researchers found.Professor Sakai was looking for a way to replace cement-based concrete with sustainable materials.Cement production releases high levels of carbon dioxide waste into the air, says research group Chatham House.Food waste is a big problem in Japan and the world.In 2019, Japan produced 5.7 million tons of food waste.The government is working on reducing this to 2.7 million by 2030.The food waste that would typically end up in landfills, rotting, and releasing methane gas, can now be used to make the concrete.
