Helping the ocean clean itself

A system to clean the ocean from plastic waste with the help of currents will start on Tsushima Island, Japan in late 201

Plastic ocean pollution kills a million of seabirds and more than 100 000 marine mammals every year. 

For years, a solution to clean up the oceans was sought but attempts were washed up, due to the high cost involved and the amount of time needed for completion of a decontamination cycle.

Now, a one-of-a-kind ocean cleaning technology by a Dutch startup, called the Ocean Cleanup Array System, intends to remove plastic pollution from the ocean by creating the longest floating structure in the world that naturally captures waste, with no costly or dangerous installations required.

The passive cleanup system features an array of floating barriers that are fixed to the seabed and catch the waste as water flows past. It relies on the ocean gyres  the large systems of rotating ocean currents – to carry plastic waste toward the floating barriers.

This enables a mechanical extraction of naturally concentrated pollution without the use of nets, which are dangerous to the marine ecosystem.

The first system, which will span over 2 000 metres, is projected to be installed near Tsushima Island, Japan by the end of 2016.

After a series of deployments of increasing scale, The Ocean Cleanup plans to deploy of a 100-kilometre system to clean up about half the Great Pacific Garbage Patch, between Hawaii and California.

If the ocean’s water is constantly moving according to predictable patterns, the cleanup duration process of the world's ocean is estimated to be completed in just 5 years.
