Each year, 11 billion kilograms of dried green coffee is processed for export, but it's only a tiny portion of the plant. Over 45 billion kilograms of cascara (the fruity pulp that surrounds the coffee bean on the plant) is also produced, and 70% is thrown to waste.

Paul Evers has come up with a solution to mitigate coffee waste, support coffee farmers, and clean up the planet by using cascara for an energy drink called Riff.
