Crew Offshore: What It Takes to Clean the Great Pacific Garbage Patch

Just because we could use a reminder that there are solutions to what might seem to be unsurmountable problems.

[reasonsforhope]

““The Great Pacific Garbage Patch can now be cleaned,” announced Dutch entrepreneur Boyan Slat, the wonderkid inventor who’s spent a decade inventing systems for waterborne litter collection.

Recent tests on his Ocean Cleanup rig called System 002, invented to tackle the 1.8 trillion pieces of plastic pollution, were a success, leading Slat to predict that most of the oceanic garbage patches could be removed by 2040.

Intersections of ocean currents have created the massive floating islands of plastic trash—five slow-moving whirlpools that pull litter from thousands of miles away into a single radius.

The largest one sits between California and Hawaii, and 27-year-old Slat has been designing and testing his systems out there, launching from San Francisco since 2013.

GNN has reported on his original design for the floating device, but his engineering team improved upon it. System 002, nicknamed “Jenny,” successfully netted 9,000 kilograms, or around 20,000 pounds in its first trial.

It’s carbon-neutral, able to capture microplastics as small as 1 millimeter in diameter, and was designed to pose absolutely no threat to wildlife thanks to its wide capture area, slow motion, alerts, and camera monitors that allow operators to spy any overly-curious marine life...

Slat estimates ten Jennies could clean half the garbage patch in five years, and if 10 Jennies were deployed to the five major ocean gyres, then 90% of all floating plastic could be removed by 2040.” -via Good News Network, 10/19/21

The Ocean Cleanup, the only organization currently tackling the Great Pacific Garbage Patch (GPGP), has just reached a milestone of 200,000 kilograms, or 220 tons of plastic removed from the ocean.

In recent years, the Dutch non-profit completed the test run of their new system 002/B which can capture multiple tons of garbage in one sequence with its large booms measuring a mile and a half in length

The GPGP is not so much an island as it is an area where major currents and winds have brought together trillions of pieces of plastic.

By using the data of the currents and the winds to estimate volumes of plastic and to guide the capture vessels, Bojan Slat, the CEO and Founder of Ocean Cleanup, believes he can clean the whole patch in just a decade.

NORTH PACIFIC GYRE NOW WORKS AS A ISLAND, WHERE COASTAL SPECIES CAN THRIVE

Researchers have recently prove that the high seas are colonized by a diverse array of coastal species, which survive and reproduce in the Great Pacific Garbage Patch, a collection of floating marine debris in the North Pacific Ocean, in the open ocean.

Researchers examined 105 items of floating plastic items collected from the Great Pacific Garbage Patch, and identified 484 marine invertebrate organisms on the debris, accounting for 46 different species, of which 37 coastal were invertebrate species from coastal habitats, largely of Western Pacific origin. Most of these coastal species possessed either direct development or asexual reproduction, possibly facilitating long-term persistence on rafts. 

The Great Pacific Garbage Patch is so huge that the findings suggest plastic pollution in the ocean might be enabling the creation of new floating ecosystems of species that are not normally able to survive in the open ocean. 

These emergent properties of plastic rafts may play an important role in sustaining diverse biofouling communities, but more research is needed to understand how such emergent properties may drive colonization, succession and trophic interactions of coastal and pelagic taxa associated with floating plastics.

What's up with all the plastic in the ocean?

Let me talk about one really sad thing - and one where the information out there is just really bad.

A lot of you will have heard about the Great Pacific Garbage Patch. And about how you should not use plastic straws and have to recycle all the plastic you use and what not, because it is killing all the poor animals and what not.

I am here to tell you... it's all a lie. All of it.

Now, let me first say: Recycling is a scam. Because of capitalism. Yes, we could recycle at least some of the plastics we use (not all of them), but for the most part we do not do that, because it just is too expensive. So most of the plastics you and I put into recycling end up in landfills... Most likely in landfills in poor nations, where the stuff gets shipped off to. We do not really do anything good with the recycling stuff. Because making new plastics is cheaper. Simple as that. Capitalism prefers the cheap stuff. So, recycling is not happening.

But also... that plastic usually is still not the biggest problem when it comes to plastic in the ocean. Like, that landfil plastics are a problem and they should not be there. But they are not the reason for the plastics in the ocean.

Now, let me first talk microplastics, even though they are off course not that much of the plastic in volume. But where does that microplastic come from? Media wants you to believe that it is just not-recycled plastic that has somehow been made small by the ocean... But that's not it.

Instead most of the microplastics come from cars. It is abrasions from tires and breaks, that collect on the roads and then through rain get slowly transported into the oceans.

But as you can see from the graph above: Most plastics in the oceans are actually macroplastics and megaplastics. So big pieces of plastic. So, what are those?

Mostly... Fishing waste. So, fishing nets, fishing lines and stuff like that, that after use get just thrown into the oceans. This is because the fishing industry is among the industries least regulated - for the simple fact that most industries that work off the ocean are hard to regulate. And of course in the end people are very unintrested in regulating such industries.

Which is also the reason for other stuff. Overfishing. Bycatch. All those things. It just is not properly regulated - and even what regulations are there are hard to enforce because... well, who is gonna enforce them out there.

So... really. To save the oceans... we gotta eat less fish.

The Beginning of the End of the Great Pacific Garbage Patch | The Ocean ...

[reasonsforhope]

SYSTEM 002 IN 2022

“We captured our first plastic from the [Great Pacific Garbage Patch] in 2019 with [our ship] System 001/B, and since then we’ve been refining our steering strategy and deepening our understanding of plastic behavior in the oceans.

In 2021 we introduced System 002, and having now demonstrated that our system can consistently harvest significant amounts of plastic, we’re currently in transition to System 03 – our largest and most efficient cleanup system so far.

After demonstrating Proof of Technology the previous year, 2022 was all about cleaning. It was a successful year for The Ocean Cleanup in the GPGP:

System 002: 2022 in numbers

8 trips into the GPGP on cleaning operations

Over 150 days at sea (including transit)

153,000 kg of plastic removed from the GPGP in 2022

4 consecutive trips with catch totals over 25,000 kg

99.9% of catch comprising only plastic

The continuity of cleaning operations during this transition was essential in demonstrating that we are moving towards our efficiency targets and progressing our plan for scale-up. Significant milestones such as the extraction that brought us over the 100,000 kg barrier in the GPGP are documented and shared with our growing community of supporters worldwide, aiding the visibility of our mission and highlighting the urgency of the plastic pollution problem...

PRIORITIZING THE MARINE ENVIRONMENT

We are committed to maximizing our net positive impact on the marine environment. In that light, we place particular importance on one particular figure from our 2022 data: 99.9%. This is the amount of our total catch that consists of plastic, leaving a level of bycatch of 0.1%.

While this is not perfect and we are working hard to reduce it further, we believe this data shows that our mitigation measures and animal protection procedures are working effectively so far. We have also seen a reduction in bycatch rates during the year (see our January 2022 mid-term evaluation) as we implement new learnings and modifications.

Our environmental performance is a result of the measures we have taken since we began our ocean operations. Our systems move very slowly, meaning fish and marine animals can easily swim away, and our crew always has the option of triggering the emergency release to free any animal which has become trapped in the Retention Zone; although this results in the loss of any plastic which has been captured, we keep this option available for any serious encounters.

Upgrades to be implemented during the transition to System 03 include more underwater cameras to allow us to more closely monitor encounters with marine life, and increasing the number of openings throughout the system to allow animals to swim out. We will also be trialing various new deterrent and mitigation measures during 2023, working with our in-house and third-party marine biologists to ensure that we continue to reduce any type of bycatch to the minimal level possible.”

The optimist in me says that this is a great development, and I'm really hoping it passes. However, as a citizen of one of the very few UN Nations opposed to this treaty--the US--I'm very well aware of how both government and industry here are prone to dig their heels in when anyone suggests anything other than profit as the primary motivator to do, well, anything.

The good news is there are plenty of us here in the US and other opposing countries who are very much in favor of reducing plastic pollution. And while putting pressure on our elected officials isn't always an absolute guarantee they'll listen, it's better than sitting back on our thumbs and doing nothing. If nothing else, it shows the rest of the world that not all of us are only concerned with money.

By the way, industry's supposed solution of "just recycle it" doesn't work. We've tried that for decades, and the vast majority of plastic hasn't ended up recycled, instead going to landfills, getting tossed out of various car windows, getting incinerated, or shipped overseas where it is either put in landfills there, or simply dumped into the ocean. There is no streamlined, cost-effective way to sort and clean plastics, and it's much cheaper to just manufacture new plastics. It's pretty obvious we need a better solution, and the one that's going to be most effective is going to be--less plastic in the first place.

If you have an hour, here's a really great PBS Newshour segment on The Plastic Problem that goes into a lot more detail about all of the above.

Since 2019, The Ocean Cleanup has been collecting the floating plastics for later recycling. And with a new $15 million grant from the Helmsley Charitable Trust — tied to World Ocean Day on June 8 — the group will continue its efforts to remove the garbage, a $189 million project that aims to ultimately remove 15 million pounds of plastic.

—

The latest iteration of the organization's system, funded by the Helmsley grant, involves a ship, which takes about five days to even reach the site, the largest plastic accumulation zone in the world. The ship then drags a nearly mile-and-a-half-long barrier at about walking pace to collect the plastic. AI monitoring allows the ship to steer toward the areas with the greatest plastic density, and underwater cameras monitor for any marine animal life caught in the "retention zone." If an animal is spotted, a safety hatch opens to allow the animal to escape.

"It was mind blowing," says Egger, who has completed the trip to the patch twice. "You have this pristine environment. It's a beautiful open ocean and you see a toothbrush just floating by, you see a kid's toy floating by. You realize the extent of the pollution that we caused is so vast that we created this garbage patch in the middle of the open ocean far away from human beings."

The Great Pacific Garbage Patch got its name from oceanographer Charles J. Moore, who coined the term after returning from a sailing race in 1997. About 85% of marine litter is plastic, according to the United Nations. Once these plastics enter a gyre, or an ocean vortex, they stay there until they degrade to microplastics.

"That garbage isn't going anywhere, it's staying in that location for the most part, breaking down, and entering our food system," said the trust's Panzierer. "It is so important for us to work collectively as an entire society to remove this because it has not only health problems for America, but has health problems for the entire globe."

Ocean plastics harm marine life, too. Animals often confuse the plastics for food because of their size and color, which can lead to malnutrition. Sea turtles caught in fisheries operating around the patch can have up to 74% of their diets composed of ocean plastics, according to The Ocean Cleanup.

And ocean wildlife can get caught and die in discarded fishing nets, also known as ghost nets, which make up 46 percent of the mass of the garbage patch according to the Ocean Cleanup.

In addition to the health effects of ocean plastic pollution, there are economic costs too — plastics in the ocean cost roughly $13 billion per year, including the clean up costs and financial losses to fisheries and other industries, according to the United Nations. The new funding will help the organization, which relies on donations, transition to using the new, more efficient cleanup system and scale it up.

To clean up the entire patch, Egger said, would cost billions.

The United Nations is currently negotiating a global plastics treaty that aims to develop a legally binding agreement to address plastic pollution by the end 2024.
