We are The Ocean Cleanup

  • Founded 2013

    Dutch inventor Boyan Slat founded The Ocean Cleanup at the age of 18.

  • Staff 70+

    The Ocean Cleanup's team consists of more than 70 engineers, researchers, scientists and computational modelers working daily to rid the world's the oceans of plastic.

  • HQ Delft

    Our headquarters are located in Delft, the Netherlands. Our operational base will be established late-2017 in San Francisco, USA.

Big problems require big solutions

The Ocean Cleanup is a non-profit organization, developing advanced technologies to rid the world’s oceans of plastic.
By utilizing the ocean currents to our advantage, our passive drifting systems are estimated to clean up half the Great Pacific Garbage Patch in 5 years’ time.

We must defuse this ticking time bomb

  • Environment

    Plastic pollution in the world's oceans is one of the biggest environmental issues of our time, impacting more than 600 marine species.

  • Economy

    According to the United Nations, plastic pollution is conservatively estimated to have a yearly financial damage of 13 billion USD. The costs stem from the plastic’s impact on marine life, tourism, fisheries and businesses.

  • Health

    Plastic pollution does not only impact sea life, it also carries toxic pollutants into the food chain – a food chain including us humans.

A simple idea turned into a moonshot project

The Ocean Cleanup is designing and developing the first feasible method to rid the world’s oceans of plastic. Every year, millions of tons of plastic enter the ocean. A significant percentage of this plastic drifts into large systems of circulating ocean currents, also known as gyres. Once trapped in a gyre, the plastic will break down into microplastics and become increasingly easier to mistake for food by sea life.
Going after it with vessels and nets would be costly, time consuming, labor intensive and lead to vast amounts of carbon emission and by-catch. That is why The Ocean Cleanup is developing a passive system, moving with the currents - just like the plastic - to catch it. The Ocean Cleanup's passive system is comprised of a floater with a solid screen underneath, concentrating the debris and leading it to a collection system. The system is slowed down by a drift anchor suspended at an approximate depth of 600 meters, making the system move slower than the plastic and therefore catching it.

"For society to progress, we should not only move forward but also clean up after ourselves."


By deploying a fleet of systems, The Ocean Cleanup has estimated to be able to remove 50% of the Great Pacific Garbage Patch in just 5 years’ time. The concentrated plastic will be brought back to shore for recycling and sold to B2C companies. The revenue gained will help fund the cleanup expansion to the other four ocean gyres.
In preparation for full-scale deployment, The Ocean Cleanup organized several expeditions to map the plastic pollution problem in the Great Pacific Garbage Patch to an unprecedented degree of detail. The team simultaneously advanced its design through a series of scale model tests, including prototypes deployed in the North Sea 2016 and 2017. System trials off the American west coast will start early 2018 and the first cleanup system deployment in the Great Pacific Garbage Patch is scheduled to take place mid-2018.
