Plastic Research

To be able to solve a problem, you have to understand it. The Ocean Cleanup has carried out research on plastic pollution since 2013 to understand the scale of the issue and the impacts of plastic pollution. Our team of in-house scientists carries out ongoing research to look at the problem in its present state and inform our engineering team of potential system innovations, but also to look ahead and adapt accordingly. Read more about our research in our scientific publications. All content below should be credited to The Ocean Cleanup.

Trawling in the Great Pacific Garbage Patch
Manta trawl deployed during Mega Expedition. With a trawl, you can see how much microplastic there is per area trawled.

The Great Pacific Garbage Patch (GPGP), as mapped by The Ocean Cleanup in 2015-2016.

Composition of the inner GPGP. Currently, about 5-10% of its mass is microplastics.
The journey of floating ocean plastic from rivers to garbage patches
Future scenarios for macroplastics in the GPGP. The dark band shows what would happen without any change. Addressing the source (left) causes the amount of ocean pollution to stay constant. Combining source reduction with cleanup (right) causes the amount of ocean pollution to decline.
