The cost of sea litter in the EU has been estimated at up to €630 million per year. It is mostly composed of plastics, which take hundreds of years to break down in nature, and has the potential to affect human health through the food chain because plastic waste is eaten by the fish that we consume.
Hardiman developed an unmanned robot, an aqua drone that cruises around urban waters such as harbours, marinas and canals, eating up marine litter like a Roomba of the sea. The waste is collected in a basket which the WasteShark then brings back to shore to be emptied, sorted and recycled.
The design of the autonomous drone is modelled on a whale shark. These giant filter feeders swim around with their mouths open and lazily eat whatever crosses their path. It’s powered by rechargeable electric batteries, ensuring that it doesn’t pollute the environment through oil spillage or exhaust fumes, and it is relatively silent, avoiding noise pollution. It produces zero carbon emissions and the device moves quite slowly, allowing fish and birds to merely swim away when it gets too close for comfort
