Founder of the world’s first zero-waste restaurant @silolondon, Douglas challenges something we’ve all accepted as normal: waste. “My name is Douglas McMaster and I design zero-waste food systems. In nature, there is no waste. There is no bin in the jungle.” From fermentation to full-system redesign, Douglas shows that if nature wastes nothing, why should we?

“We still have the space to restore one trillion trees. Can you imagine? My name’s Šimon Michalčík.
