One third of all the food we produce is thrown away. These ‘residual flows’ of food do not currently have a fully-fledged repurposing. They end up as waste or are used for green energy production. A new generation of designers is showing the enormous potential of these food wastes by converting them into high-quality building materials. By strengthening cooperation between the food and construction sectors, we reduce waste and create value again with what we don’t eat.

Imagine, one day you might be watching a movie in a movie theater with walls made of popcorn while you are drinking from a cup made out of potato starch.
