Scientists at the University of Tokyo have invented a new method that can turn food waste into cement. They claim that it could help tackle problems such as food waste and global warming.
The method is quite simple. First, the scientists dry the food waste, then they crush the waste to make powders, and this powder finally gets pressed into mold.
The researchers found out that many foods can turn into “edible cement”. For example, banana peels, onions, orange peels, tea leaves, coffee grounds, and pumpkins can all be used.
The researchers also found out that these materials can even be stronger than cement. For instance, cabbage leaves cement could end being four times stronger than normal cement.
Researchers of Japan also say that the cement could be made into food again. All that would have to be done is to break the cement and cook it!
According to the UN Environment Programme’s Food Waste Index, more than 900 million tons of food is thrown away every year globally. If we had this cement, the big problem will be solved.
Because of the cement, maybe we humans can live on earth longer.
