The London Marathon's method for reducing plastic bottles: Edible seaweed pouches


The London Marathon debuted a new, environmentally conscious way of keeping runners hydrated: edible seaweed pouches filled with sports drink. The pouches, or “Ooho,” created by Skipping Rocks Labs, can be eaten along with the liquid inside of them, or users can bite the corner and drink the contents, discarding the seaweed wrapping. This was the first mass use of such pouches, with the hope that they can be used to cut down on plastic at large scale events in the future.
