The quantity of plastic waste is rapidly increasing in rivers, lakes and oceans across the world. Over 245 million tonnes of plastic waste is floating on the surface of oceans, while tonnes of heavy waste materials are present on the floor of these oceans. The presence of plastic waste in waterways has affected all kinds of living beings, including birds, fish, humans, etc.
One of the largest patches of floating plastic and other waste materials present on the surface of oceans is spread over 1.6 million square kilometres in the pacific. There are four similar patches present in the oceans, which are relatively smaller than the one in pacific.
Undoubtedly, it is not an easy job to clean up these patches of garbage only through manpower. However, with the help of water robots, this activity can be performed rather easily. These water robots can operate independently and clean the plastic patches faster with great accuracy.
One such autonomous surface vehicles or water robot, known as WasteShark can clean up to 200 litres of ocean waste before being emptied. Inspired by whale sharks, WasteShark floats through the sea just like the former with its mouth open, collecting garbage instead of fish. Developed by RanMarine Technology, WasteShark moves gently that prevents it from posing any danger to the ocean life. It also collects data about water quality, providing insights into how fast plastic is degrading in the seas.
