Dutch inventor unveils river barge to scoop plastic before it enters oceans

The Ocean Cleanup nonprofit aims to deploy "The Interceptor" in 1,000 rivers responsible for 80% of plastic entering oceans. It should use natural currents to collect plastic, while allowing animals and ships to pass.

A Dutch foundation striving to remove plastic from the world's oceans unveiled on Saturday an invention to remove waste in rivers before it enters the sea.

The Ocean Cleanup says the barge called "The Interceptor" will "close the tap" on the greatest source of plastic entering oceans.

The nonprofit established by 25-year-old Boyan Slat estimates that 80% of river plastic stems from just 1,000 rivers, the main arteries that carry waste from land to the ocean.

The 24-meter-long (79 feet), solar-powered barge will be anchored at strategic locations in rivers and use natural currents to collect plastic, while allowing animals and ships to pass. The invention uses a barrier that guides plastic into a mouth-like bow, from where it rolls up a conveyer belt and is dumped into six dumpsters.

The autonomous barge has a capacity of 50 tons of plastic, working around the clock. Once full, a computer sends a message to operators, who then empty the dumpsters and send the contents to local waste management facilities. Under optimal conditions, the barge could collect up to 100 tons per day.

The project will attempt to deploy the system in the world's 1,000 most polluting rivers within five years, The Ocean Cleanup said.

Prototypes of the device have already been tested in Jakarta, Indonesia and Kuala Lumpur, Malaysia. Two more are ready to be put into action in Vietnam and the Dominican Republic.

Earlier this month, The Ocean Cleanup announced that its specially designed ship and large floating boom had successfully hauled in its first plastic from the "Great Pacific Garbage Patch."

The organization had previously been criticized for focusing on cleaning up ocean garbage and not addressing rivers as the main source of the 9 million tons (8 million metric tons) of plastic that enters the ocean annually.
