A Dutch Teenager Had a Dream to Clean Up the World's Oceans. 7 Years On, It's Coming True

By Billy Perrigo, Time

or someone who gets violently seasick, Boyan Slat spends a lot of time thinking about the ocean. The Dutch inventor has designed the world’s first ocean plastic cleanup system but admits he won’t be on the ship with it when it launches out of San Francisco on Saturday. “I am not a man of the sea,” he says.

After five and a half years of hard work, the 23-year-old Slat will watch from dry land as System 001 — a floating barrier nearly 2,000ft long — snakes its way out under the Golden Gate Bridge into the Pacific. Its destination is the Great Pacific Garbage Patch, a gyre of plastic waste twice the size of Texas held in position by ocean currents between California and Hawaii.

If all goes to plan, Slat says, an array of 60 systems could reduce the amount of plastic there by half by 2025. “I hope that this will be a turning point for the plastic pollution problem,” Slat tells TIME in a phone interview a few days before the launch, in between final preparations. “For sixty years it has only gotten worse and worse. Now hopefully we’re turning the tide.”

The eradication of the garbage patch, and more broadly the salvation of our oceans, has been Slat’s single-minded goal ever since he was 16 years old, when a diving trip to Greece yielded more plastic bag sightings than fish. Struck by the idea for a floating barrier that could collect plastic using the power of ocean currents alone, he founded his company, The Ocean Cleanup, aged just 18.

The idea grabbed imaginations around the world. In 2015, an early prototype of System 001 was featured on TIME’s list of the best inventions of 2015. The project has come a long way since then, Slat says. “It takes a trained eye to see the similarities.”

What was originally envisaged as a large rigid barrier arranged around a central tank for collecting plastic, is today an unmanned, modular system that moves with the currents, naturally gravitating to areas of higher concentration. From the air it looks like a pipeline sitting on the surface of the sea, but beneath the waves lies a 10ft deep ‘skirt,’ which traps plastic accumulated by the current.

Because the system is solid rather than a net, Slat says sea life will be protected from becoming ensnared. The hope is that plastic will accumulate as if on a seashore, ready to be collected by boats and taken for recycling.

It’s an ambitious plan, and one that has received millions of dollars of funding thanks to fast-shifting public opinion on plastic. In December 2017, 193 countries signed a U.N. resolution to eliminate ocean plastic pollution, and big corporations like McDonald’s are moving to remove single-use plastics from their stores. (Some say not fast enough.) The U.N. says over 8 million tons of plastic still enter the oceans each year – the equivalent of a garbage truck full of plastic every minute.

But reducing our addiction to plastic is just one half of the equation, Slat says. “These garbage patches won’t go away by themselves. Even if we were to close the tap today the plastic would still be there in 100 years.”

Slat sees his mission as a race against time. Plastic gradually breaks down into smaller and smaller pieces called microplastics which can eventually enter the food chain. Currently, however, just 8% of the plastic mass in the Pacific garbage patch is microplastics, according to research carried out by The Ocean Cleanup published in the journal Scientific Reports. “But of course what’s going to happen over the next few decades is that all the other 92% of plastic will be turned into microplastics as well,” Slat says. “So the sooner we get it out, the better.”

A thorny question remains in what will happen to the plastic that is brought back to shore from The Ocean Cleanup’s systems. Slat says he wants to turn it into branded merchandise, but acknowledges that all depends on the quality of the plastic, which remains a mystery. In any case, most of the plastic in the oceans is single-use, Slat argues. “By not making it into anything single-use, you can already reduce the chances of it ending up back in the oceans by 99%,” he says.

But it’s possible that lots of the waste returned to land will have to be carted off to third-party recycling plants and eventually recycled into more single-use plastics that might one day return to the oceans. The task ahead isn’t so much Herculean as Sisyphean.

Nevertheless, Slat isn’t dissuaded easily. “Big problems require big solutions,” he says. “If anyone has any better ideas, we’d love to know.”

A note of caution regarding our comment sections:

For months a stream of media reports have warned of coordinated propaganda efforts targeting political websites based in the U.S., particularly in the run-up to the 2016 presidential election.

We too were alarmed at the patterns we were, and still are, seeing. It is clear that the provocateurs are far more savvy, disciplined, and purposeful than anything we have ever experienced before.

It is also clear that we still have elements of the same activity in our article discussion forums at this time.

We have hosted and encouraged reader expression since the turn of the century. The comments of our readers are the most vibrant, best-used interactive feature at Reader Supported News. Accordingly, we are strongly resistant to interrupting those services.

It is, however, important to note that in all likelihood hardened operatives are attempting to shape the dialog our community seeks to engage in.

Adapt and overcome.

Compress the collected plastic with heat and hydraulics into bricks that houses can be built with.

Good idea, and even better would be to make benches and garden paver "stones" that could be sold retail to those who want to support the efforts to clean up the ocean. Maybe another product for apartment dwellers, like buying a brick that would be used to build s playground or house?

Not to be sold. To be donated for use housing for poor people who live in areas around the world where plastic bricks would be environmentally suitable.

Does it rot or does it not?

Ban the manufacture of anything that isn't biodegradable or easily and widely recyclable. Manufacturers must demonstrate what will happen to their product when consumers no longer want it. The cost of "dealing" with the product when no longer wanted must be built into the original cost.

Otherwise prepare to be engulfed by unwanted non-biodegradab le human artifacts, whether on land or on sea.

Bravo to Mr. Slat for devising a way to corral ocean plastic litter.
