Drones for Trash Clean Up in Waterways Could Save the Oceans

City of Aarhus, Denmark

A project using drones for trash clean up in Denmark could show the way to saving the oceans from an environmental disaster caused by the massive volume of plastic that pollutes them.  (Part two of a two-part series on the use of drone-captured images and machine-learning software in the cause of cleaning up the environment.)

Project combines use of flying, floating drones for trash ID and collection, to clean up Danish waterways

Denmark has launched a unique experimental project, combining both unmanned aerial vehicles and unmanned watercraft to combat oil slicks and floating trash in the nation’s waters.

The CityShark program, designed to coordinate the use of the two different types of drones, began in July 2019, with the use by the Danish coastal city of Aarhus of WasteShark, an unmanned waste-gobbling sailing vessel, manufactured by Rotterdam-based RanMarine Technology.
In the first phase of the project, the WasteShark, owned by the Port of Aarhus, autonomously roamed the waters at the mouth of the Aarhus River where the river flows into the harbor, and scooped up solid waste — plastic bottles, single-use cups, plastic bags and other floating debris. The WasteShark is able to collect 500 kilograms (about 1,100 pounds) of debris each day.
