Scientists turn food scraps like banana peels, seaweed and cabbage leaves into construction materials that are 'at least as strong as concrete'

Researchers in Japan created a way to turn food waste, such as banana peels or cabbage leaves into building products for construction

They used a 'heat pressing' concept that turns wood powder into construction materials

They tweaked that by using vacuum-dried food scraps instead and mixing the food powder with water, seasonings and put it at a temperature to test the strength, taste, smell and appearance
All of the materials exceeded the researchers strength targets, except for pumpkins

Chinese cabbage leaves 'produced a material over three times stronger than concrete'

The material was not negatively impacted by rot, fungi, or insects and there was no 'appreciable changes' to appearance or taste after being exposed to air for four months
The World Food Program estimates that one-third of the world's food is wasted every year, or $1 trillion worth
