275: WasteShark


A marine robot or aquadrone to eat waste and collect data.
Oliver Cunningham and Richard Hardiman co-founded RanMarine Technology in Rotterdam, the Netherlands to launch the The WasteShark, the world’s first marine robot designed specifically to capture plastics, microplastics, oils and other pollutants and collect data. Hardiman, from Cape Town, South Africa wanted to create a device that could help clean trash out of a harbour before it reached the ocean.

WasteShark floats through the sea just like the former with its mouth open, collecting garbage instead of fish As it navigates the water the electrically-propelled WasteShark emits no carbon, produces no noise or light pollution, and poses no threat to wildlife.

It can travel up to 5 km and collect up to 350kg of waste at a time.  WasteShark is also supported by a docking- and recharging station. One WasteShark can collect in excess of 15 tonnes of waste a year, with the plastic recycled to make products.

With 10 WasteSharks being tested around the world in India, the Netherlands, the U.S., and Cape Town, from December 2020, WWF and Sky Ocean Rescue launched a WasteShark in north Devon, England to clean up Ilfracombe harbour
