The seabin works by creating a flow of water into the bin, bringing with it any surrounding debris that is then caught in the net. According to the Seabin Project website, the device can catch 1.5 kilograms (about 3.3 pounds) of debris per day, with the ability to hold up to 12 kilograms (26.5 pounds) at full capacity. The creators estimate each seabin can remove about half a ton of debris every year, the equivalent of collecting about 20,000 bottles or 83,000 plastic bags.
