US alternative design company Greenaid have been marketing their urban ecology solutions, Seedbombs via vending machines placed in forward thinking retail establishments in the States. They have just started to make their way across the Atlantic and so far there is just one in the UK located in London’s Selfridges.
The seedbombs are made from a combination of clay, compost and seeds and designed to explode into a fertile growing medium upon impact. You can also purchase catapults made precisely for the job. What a great way to brighten up a grey expanse of concrete!
