For hundreds of years, people have used the ocean in addition to contemporary waterways as a type of dumping floor for varied sorts of air pollution, like manufacturing facility farm runoff, oil, and sewage. Because of this, in america alone, half of all rivers are too polluted to help wholesome aquatic life.  And that air pollution oftentimes makes it again into our our bodies ultimately or one other, normally by the use of our meals and water.
Stable refuse like plastics, glass, polystyrene, and different supplies are additionally generally dumped in rivers when no different choices for correct disposal can be found. These rivers ultimately run to the seas the place they accumulate in gyres. The NOAA defines gyres as a “massive system of rotating ocean currents.” 
“Wind, tides, and variations in temperature and salinity drive ocean currents,” the NOAA writes on its web site. “The ocean churns up several types of currents, resembling eddies, whirlpools, or deep ocean currents. Bigger, sustained currents—the Gulf Stream, for instance—go by correct names. Taken collectively, these bigger and extra everlasting currents make up the techniques of currents often called gyres.”
There are 5 major gyres on Earth. They’re situated within the North Pacific, South Pacific, the North Atlantic and South Atlantic, and one within the Indian ocean.
Being a degree of confluence for a number of currents, these gyres are capable of simply accumulate particles flowing in from rivers and different sources, forming large “garbage islands” in varied elements of the ocean. The affect of our rubbish reaching the ocean is far-reaching. It’s estimated that our plastic pollution kills 1 million sea birds and 100,000 sea turtles and different marine mammals, like dolphins, whales and seals, each single yr. 
Stopping this litter at its supply is important to stopping this hurt to wildlife and the atmosphere by which they reside in addition to defending human lives impacted by this refuse. In 2018, analysis performed by the Worldwide Union for Conservation of Nature, or IUCN, concluded that “greater than 1 / 4 of all of the world’s marine plastic waste could also be pouring in from just 10 rivers, eight of them in Asia.”  One Asian nation, Malaysia, is now working to show the tide, so to talk, on this horrible challenge.
Enter: Photo voltaic Powered Barges
On the Klang river close to Kuala Lumpur, officers have deployed a solar-powered trash collection barge known as The Interceptor, in an try and take away plastic, and different sorts of strong refuse, from the Klang River. The barge is a complete of 78 toes lengthy (24 meters) and appears a bit like a houseboat. Trash within the river is directed towards a gap within the barge the place a conveyor belt collects it and shops it in a big dumpster within the barge.
The Interceptor is able to eradicating 50 tons of refuse daily. The barge has been deployed on the Klang river since October.
The solar-powered cleanup barge was developed by The Ocean Cleanup, a non-profit group situated within the Netherlands. Ocean Cleanup has been working with Landasan Lumayan, a Malaysian authorities firm, to scrub the river since 2016. Based on the Dutch group, their work has been paying off.
“The Klang river was like a floating landfill,” stated Syaiful Azmen Nordin, the managing director of Landasan Lumayan. “Boats couldn’t cross by, and there was lots of plastic. Now you possibly can see the river is usually free from floating particles.”
Based on Ocean Cleanup, 80% of plastic waste within the oceans originates from roughly 1,000 rivers globally.  The Klang river is accountable for 15,000 tons of plastic getting into the ocean every year, making it one of many worst polluters on the planet. The group hopes that, following the successes of the river cleanup barge, these barges will be deployed in all of those polluting waterways.
“We all know the objective of 1,000 rivers is bold, however it’s a mandatory one,” stated Ocean Cleanup spokesperson Joost Dubois. The Interceptor prices roughly $775,000 USD to construct, although Ocean Cleanup expects that the price of producing these barges will doubtless drop over time. In whole, they’ve constructed 4 Interceptor barges.
Interceptors are being despatched to Thailand, Vietnam, and the Dominican Republic to assist clear up rivers in every of these international locations.
In Malaysia, the trash faraway from the Klang river is shipped on to the landfill. The barge has collected a wide selection of refuse, from discarded teddy bears to tires. A brand new effort is being made to separate out recyclable gadgets from the trash, serving to to shut the loop on a few of the waste.
Whereas the Interceptor barges are having a big impact by themselves, decreasing our use of plastics, notably single-use plastic, is important to turning the tide on this struggle.
