Recently, portmouth Portsmouth in the south of England started to put on a kind of 'floating sea trash can' that can suck waste such as plastic bottles, plastic bags and cigarette butts from the sea.
A floating marine trash can uses a submersible pump to suck the sea water together with the water-laden rubbish, and then through a storage bag in the bucket to retain all the litter more than 2 mm in diameter to filter out seawater. 12 kg, after full replacement.
According to preliminary estimates, this trash can collect 1.5 kilograms of waste per day, which amounts to 20,000 plastic bottles or 83,000 plastic bags each year.
In addition, this trash can also collect the slick on the sea.
The inventor of the floating sea bins, two Australian surfers, spurred them to develop the trash can because they really had enough of the "wave after wave" of rubbish they'd come across.
The trash bin was tested at some docks in many parts of the world before Portsmouth Harbor was officially launched. The most common trash it collected was bags of cigarettes, plastic chips and potato chips.
According to the two inventors, generally speaking, one marina needs about four such floating trash cans to be put in areas where the tides and currents cause waste to accumulate.
According to the data reported by Reuters, at present, on average, 8 million tons of plastic wastes thrown into the ocean each year, of which only 9% can be recycled, while less than 20% of the 8 million tons of plastic wastes Because of human normal sea activities, such as fishing.
