“Over 30,000 edible drinks capsules made from seaweed were handed out to runners at the London Marathon yesterday, in a bid to reduce plastic waste. The marathon was the largest ever trial of Ooho capsules – biodegradable pods that can be filled with water or other beverages.You can either consume the pods whole, or bite into them to release the liquid. Made from a seaweed-based substance, the discarded wrapping will naturally decompose in four to six weeks – roughly the same time as a piece of fruit.
Introduction of the capsules formed part of a push from London Marathon organisers to make this year's event the most sustainable marathon ever.
Last year an estimated 760,000 plastic bottles were thrown onto the city's streets by runners and spectators. The target for 2019 was to bring this number down by 215,000.”
