Seabin is an Australian invention. It's a floating debris interception device designed to be installed in the water of marinas, yacht clubs, ports and any water body with a calm environment and services available. It's installed in a specific debris problem area in the marina on a floating dock and the wind and the currents bring the debris directly to the Seabin.
The catch bag can hold up to 12Kgs of debris. Trials of these Seabins are being conducted around the world, most recently in the UK at Portsmouth Harbour. https://www.engadget.com/2017/10/11/seabin-portsmouth-harbour/
