This week on Dezeen, the impact of plastic on the environment was yet again a talking point, as the London Marathon gave out drinks in edible seaweed capsules and a study revealed the truth behind biodegradable bags.
On Sunday, over 30,000 biodegradable Ooho capsules were handed out to runners at the London Marathon, marking the largest ever trial of the drinks pods.
Designed to reduce plastic waste, the pods are made from a seaweed-based substance and can be filled with water or other beverages. The wrappers can be consumed or dropped on the ground, as they naturally decompose in under six weeks.
Meanwhile the University of Plymouth revealed the results of its study that found "biodegradable" plastic bags remain intact and useable three years after being dropped in the sea or buried underground.
Five types of plastic carrier bag were used for the experiment, which was conducted over three years in soil and marine environments. The biodegradable bag, the oxo-biodegradable bag and the standard plastic bag all remained fully functional.
