The last version of the Ocean Cleanup's concept failed out at sea, but now a new version is cleaning up the waves.
UK scientists are investigating a natural solution to microplastic pollution in our oceans: mussels. These molluscs serve as efficient water purifiers, but can they make a real dent in our pollution problem?
Cleaning up plastic in the ocean requires first spotting it. New research suggests that a combination of AI and satellite technology could make the process easier, cheaper and more effective.
Not only can drones fly, some can also swim. One drone, the WasteShark, which is currently on the move in the ports of Rotterdam and Dubai, even collects garbage.
