Each year, eight million tons of plastic waste finds its way into the oceans. Much of this pollution is carried from cities to the sea, via rivers. Now, innovative solutions are emerging to help clean up these waterways, like WasteShark, a water-based cleaning robot that removes floating pollution.

In recent days, the residents of London’s Canary Wharf might have noticed a strange waterborne robot floating in the Thames. Named the WasteShark, this machine’s mission is to eliminate floating waste in order to prevent its proliferation in the oceans. Canary Wharf is a busy financial district of the British capital, where single-use plastic, like coffee cups and food packaging, can cause pollution both on land and in the water.
