WasteShark catches plastic and other waste. RanMarine’s promising prototype has developed into a mature water robot that cleans water worldwide. Creator Mr Richard Hardiman said “The idea for the WasteShark originated in South Africa, where Hardiman comes from. I saw two people fishing rubbish out of the water with fishing net. I thought surely there must be a different and better way of doing that. And that’s how the idea for the WasteShark was born. I have an engineering background so I started building. In 2016 I came into contact with the PortXL programme that allowed me to develop my idea as part of my newly established startup RanMarine.”Mr Hardiman ended up at RDM Rotterdam, where he continued to develop his shark He said “The WasteShark is a mini-water robot that floats and can navigate autonomously. It scours the surface of the water for plastic, waste and pollution and other things that do not belong in the water. The WasteShark collects it in its ‘open mouth’ and brings it to the shore. The smart shark can also pick up natural material that impacts water quality, such as duckweed, algae and aquatic plants. In addition, the WasteShark collects data on water quality. For example, it can monitor whether outboard water is suitable for swimming.”Mr Hardiman said “The WasteShark is controlled via 4G, has a range of 3 kilometres, reaches a speed of 3 kilometres per hour and can swim for about 6 hours. The water robot is 1.57 metres long, 1.09 metres wide, 52 centimetres high and weighs 75 kilos.”WasteSharks are now swimming around the world: from South Korea, Australia, United States and the UK to the Netherlands. They are used in marinas, industrial ports, in the tourism sector, and by governments or organisations such as the World Wildlife Fund and the United Nations that want, for instance, to keep canals, lakes and rivers clean.
