Why I’m a rubbish collector for the world’s oceans


I’m the founder and chief govt of The Ocean Cleanup, a non-profit group based mostly in Rotterdam, the Netherlands, that goals to take away plastic air pollution from the oceans. My workforce and I do that in two predominant methods: by dragging nets throughout areas the place plastic accumulates, such because the Nice Pacific Rubbish Patch, a set of particles within the North Pacific Ocean; and by intercepting waste in rivers earlier than it reaches the ocean. We wish to scale back ocean plastic air pollution by 90% by 2040.

This photograph was taken in Guatemala close to the mouth of the Motagua River, downstream of Guatemala Metropolis and an enormous landfill. Yearly, round 20,000 tonnes of plastic stream down the river into the Caribbean Sea. In mid-2022, we put an eight-metre-high avalanche fence throughout the river to catch the plastic. Quickly after, heavy rains washed about a million kilogrammes of waste down the river in 20 minutes, inflicting the foundations of our fence to fail. Within the image, I’m assessing the aftermath of that occasion. We are actually engineering an improved model of the barrier, which we hope shall be in place earlier than the subsequent wet season.

There’s a lot we don’t perceive about plastic air pollution within the oceans. Once we began, we knew concerning the Nice Pacific Rubbish Patch, however we didn’t know the way huge it was or how a lot plastic enters the oceans yearly. Plastic can take many years to interrupt down — within the Pacific rubbish patch, a lot of the garbage is from the Nineties, and we now have even discovered gadgets from the Sixties.

The Ocean Cleanup has greater than 100 workers members, together with scientists. We attempt to be a haven for researchers who wish to do utilized analysis and make a distinction. To this point, we’ve eliminated round two million kilogrammes of garbage from rivers and the ocean, together with about 200,000 kilogrammes from the Pacific rubbish patch. That’s solely a tiny quantity — about 0.2% of what we estimate is within the rubbish patch. However we hope to dramatically improve the quantity of plastic eliminated.
