Ever been hungry enough to eat a house? Now, you actually could.

Food waste is a big problem in Japan and globally. Japan produced around 5.7 million tons of food waste in 2019. The government plans to reduce that by around 2.7 million tons by 2030. Tokyo University researchers Kota Machida and Yuya Sakai have developed a way to transform food waste into cement (水泥) for construction use and more. This is the first-ever process created for making cement entirely from food waste. The researchers say their product is four times as strong as traditional concrete. This particular cement can be used to make things like tea cups or chairs as well. However, there’s one additional feature — it’s also eatable.

Kota and Yuya are the intelligence behind the formation of Fabula Inc., a company with purposes of reducing food waste, and helping fight global warming. As expected, something this unique took years to develop. It took a few attempts to find just the right process. Kota and Yuya created the unique technology while researching possible environment-friendly materials to replace cement-based concrete. Cement production accounts for 8% of the world’s carbon dioxide release.

After a few failures, they realized they could get the cement to bind (黏合) by adjusting the temperatures. “The most challenging part was that each type of food waste requires different temperatures,” Yuya said. So the researchers had to observe them and respond in time. In the experiments, Kota and Yuya have successfully made cement using tea leaves, coffee grounds, cabbage and even lunchbox leftovers.

Fabula Inc. is currently working to make tea cups and furniture, but Yuya is thinking a little bit bigger. Their product could provide relief in the form of eatable emergency shelters in disaster ones. “For example, if food cannot be delivered to the people, they could eat makeshift beds made out of food cement,” he said. To eat the material, a person needs to break it apart and boil it.
