At present, Kota Machida and Yuya Sakai, researchers at the University of Tokyo in Japan, have developed the world's first process to completely extract cement from food waste. They convert food waste such as cabbage leaves and orange peels into biodegradable cement for building manufacturing.
The cement product has nearly four times the tensile or flexural strength of regular concrete, the researchers said, and they hope the construction technology will help mitigate global warming, reduce food waste and methane gas when food waste is disposed of in landfills. It is reported that the technology was developed when scientists were researching sustainable materials that could replace cement-based concrete.
At present, cement production accounts for 8% of global carbon dioxide emissions, and it is imminent to make biodegradable concrete materials. Previously, scientists initially developed the initial biodegradable concrete technology, which is to thermally compress crushed wood particles, using simple mixing and compression technology. , realize the three steps of drying, crushing and compressing the material, and sell the material on the website.
