Researchers at Tokyo University have processed food waste into cement that could be used to build shelters after a disastrous event.

Yuya Sakai and Kota Machida pulverized the waste and heat-molded it to form cement that was generally stronger than normal cement, with cabbage creating the strongest material of all.

Scientists in Japan have developed a way of turning food waste into ‘edible cement’ which could be used to build houses in the future.

Experts hope that it could help towards tackling the problems of food waste and global warming.

What did scientists do?

Researchers at the University of Tokyo have successfully made a concrete-like building material from leftover food.

It’s the first time that cement has been made entirely from food waste.

They found that a variety of foods could be used including banana peel, onions, orange peel, tea leaves, coffee grounds, pumpkin and seaweed.

Scientists dried and powdered the waste vegetables and then heat-pressed them in a mould.
