A Giant Floating Machine is Now Cleaning Up the Great Pacific Garbage Patch

In a historic first, a huge floating device designed by Dutch conservationist to clean up an island of rubbish in the Pacific Ocean, which is three times the size of France has successfully picked up plastic from the high seas for the first time.

Invented by 25- year- old, Dutch inventor and engineer- Boyan Slat, the cleanup machine has a large line of cork floats holding a huge skirt that traps the garbage.

Slat, the creator of the Ocean Cleanup project, tweeted that the 600 metre-long (2,000ft) free-floating boom had captured and retained debris from what is known as the Great Pacific Garbage Patch.

The massive cleaning system is designed to not only collect discarded fishing nets and large visible plastic objects, but also microplastics.

The plastic barrier floating on the surface of the sea has a three metre-deep (10ft) screen below it, which is intended to trap some of the 1.8tn pieces of plastic without disturbing the marine life below.

The device is fitted with transmitters and sensors, so it can communicate its position via satellites to a vessel, that will collect the gathered rubbish every few months.

Slat informed media that the problem he was seeking to solve was the vast expense that would come with using a trawler to collect plastics.

He said, “We are now catching plastics. After beginning this journey seven years ago, this first year of testing in the unforgivable environment of the high seas strongly indicates that our vision is attainable and that the beginning of our mission to rid the ocean of plastic garbage, which has accumulated for decades, is within our sights”.

He further added, “We now have a self-contained system in the Great Pacific Garbage Patch that is using the natural forces of the ocean to passively catch and concentrate plastics. This now gives us sufficient confidence in the general concept to keep going on this project.”

The plastic gathered so far will be brought to shore in December for recycling. The project creator believes there may be a premium market for items that have been made using plastic reclaimed from the ocean.

“I think in a few years’ time when we have the full-scale fleet out there, I think it should be possible to cover the operational cost of the cleanup operation using the plastic harvested,” Slat added.

While elaborating about future actions, the creator said, “The plan is to now scale up the device and make it more durable, so it can retain plastic for up to a year or possibly longer before collection is necessary”.

Earlier during a four-month trial the boom broke apart and no plastic was collected. Since then, changes have been made to the design including the addition of a ‘parachute anchor’ to slow down the device’s movement in the ocean, allowing for faster-moving plastic debris to float into the system.

The latest trial began in June when the system was launched into the sea from Vancouver. The project was started in 2013 and its design has undergone several major revisions. It is hoped the final design, will be able to clean up half of the debris in the Great Pacific Garbage Patch.
