'Ocean Cleanup' Removes First 100,000 kg of Plastic From the Great Pacific Garbage Patch 106

The Ocean Cleanup, a nonprofit trying to rid the world's oceans of plastic, announced that it's "officially removed more than 100,000 kg of plastic from the Great Pacific Garbage Patch (GPGP)." The impressive milestone is almost 4x as much garbage it announced it removed last October. CEO Boyan Slat writes in a press release: Since deployment in August 2021, System 002 (or "Jenny") has now collected 101,353 kg of plastic over 45 extractions, sweeping an area of ocean of over 3000km2 -- comparable to the size of Luxembourg or Rhode Island. Added to the 7,173 kg of plastic captured by our previous prototype systems, The Ocean Cleanup has now collected 108,526 kg of plastic from the GPGP -- more than the combined weight of two and a half Boeing 737-800s, or the dry weight of a space shuttle!

According to our 2018 study in which we mapped the patch, the total amount of accumulated plastic is 79,000,000 kg, or 100,000,000 kg if we include the Outer GPGP. Thus, if we repeat this 100,000 kg haul 1,000 times -- the Great Pacific Garbage Patch will be gone.

I'm proud of The Ocean Cleanup team for crossing this milestone, which is all the more remarkable considering System 002 is still an experimental system. Now our technology is validated, we are ready to move on to our new and expanded System 03, which is expected to capture plastic at a rate potentially 10 times higher than System 002 through a combination of increased size, improved efficiency, and increased uptime. Our transition to System 03 is starting soon.

    Sure as long as no more gets added.

    • I suppose a logical question is therefore whether they can eventually deploy enough 03's (or future versions) to clean up the GPGP faster than it can accumulate.

          It is a thousand times cheaper to clean up the trash at the source than to send ships out into the middle of the Pacific.

          They removed 100 tonnes of trash. At the source, they could have paid a guy with a rake $1 per hour to do that in a week.

          This is what the plastic trash looks like at the source [weforum.org].

              I still wonder if they're missing a potential source of funding. Plastics in seawater slowly chelate metals (alongside many organic compounds), concentrating them. This is normally considered a problem, as it makes drifting plastic more toxic to sea life than fresh plastic. But chelation in plastics can generally be reversed relatively trivially with a sulfuric acid bath - and some of these metals are valuable. To the point that a number of research projects have *deliberately* left plastics in the ocean

            But... The trash is no longer at the source... Its in the middle of the ocean!

            Sure, it is a thousand times cheaper to prevent the patch from coming into existence by catching the trash at the source. But that ship has sailed. Now we need to do both.
            Also not all trash is so "nicely" concentrated as your picture wants to imply.

            • Now we need to do both.

              No, we don't. If X and Y solve the same problem, X is a thousand times more effective than Y, and you have limited resources, you do ONLY X until it is 99.9% done.

              • I'm not following - the GPGP is already there, so if you cut off the source that's great, but you still have a bunch of trash in the pacific. I think that's the point - both things need to happen: clean up the mess and stop the source. If you have a burst pipe in your basement, you need to both cut off the water supply and clean up the water that already there.

                I agree that cutting off supply is cheaper (and should happen), but I suspect that requires a lot of cooperation and coordination that is probably po

              • X (plastic patch) and Y (ocean plastic source) are not the same problem.
                Y is the source of X. So Y, having created X, makes X worse continuously. Solving Y only stops X from getting worse.
                X still is there, as it has already been created and supersized over the years...

                In a normal sentence: Stopping the outflow of garbage from the continents will not make the patch magically disappear.

                If you can't do both, yes, stopping the outflow is the minimal way to go. But right now we can do both.

                • Stopping the outflow of garbage from the continents will not make the patch magically disappear.

                  Yes, it does. The plastic eventually breaks down. Much of the plastic in the "garbage patch" is already broken down into microparticles. They degrade due to UV and from bacteria.

                  Cutting off the source (eventually) solves the problem.

                  Pulling trash from the ocean while dumping far more solves nothing.

                    Plastic microparticles concentrate pollutants and they get ingested by marine biota. Pulling trash from the ocean solves that problem.

              • The garbage patch is in international waters. Are you suggesting invading sovereign lands for trash removal? It's not as simple as that, I don't think.

              • by chefren ( 17219 )
                If the same resources are used for X and Y then sure. But in this case, "guy with rake" is not going to be collecting trash from the ocean, so to maximise the resource utilisation you want to do at least a little of both. Plus, the ocean cleanup is still a proof-of-concept that needs to be done before we can even say which one is more efficient, doing it the other 999 times (with system 003) is Y in this equation.

          It may be more effective, less environmentally damaging, & less morally questionable to just stop subsidising & legally/politically protecting the fossil fuel industry, which produces all the plastic.

      Some hippies pull 100 000kg of plastic and send it off to some "recycling centre". Instead of actually recycling the plastic, it is shipped off to some 3rd world country because it is cheaper. The country then dumps the plastic back in the ocean. Eventually it ends up back in the great garbage patch and the cycle is complete. And that boys and girls, is the true meaning of recycling....

        The plastic will cycle back one way or another. Left to its own devices, it will be broken down into fine particulates (microplastics) that enter the food and water supply and endanger animal life (including our own). Efforts like this try to skip that part and return the waste to us in forms that can still be processed into something useful and safe. Short of just banning disposable plastics, this makes perfect sense.

            I am not anti-recycling when it makes sense, but it often doesn't. Recycling aluminum, steel, and cardboard makes sense. Recycling glass, other paper, and most plastic usually does not make sense. More resources are consumed than saved.

            But the biggest problem is that people who drive 4-ton SUVs think they are "doing their part" for the environment by driving 20 miles to the recycling center with 100 grams of plastic grocery bags. Even when recycling makes sense, it makes so little difference that it is mostly a diversion from higher priorities.

            It is far better to advocate not using so much crap in the first place. I don't buy anything in disposable plastic bottles. I don't eat at fast food restaurants. I refuse to use plastic utensils. I drive an EV. I have solar panels on my roof. And I recycle when it makes sense.

              Plastic could actually be recycled effectively, for example using solar powered thermal de-polymerization resulting in a hydrocarbon mix that can be used as feed stock for a refinery.

              Unfortunately it's a bit more profitable to swear blind you'll recycle responsively, collect your fee and then ship it to a landfill in the 3rd world. And there's little enforcement or repercussions should authorities accidentally trip over solid evidence of wrong-doing.

                Perhaps. But the relevant point is that it isn't.

Probably better to throw it away even if you aren't sure it will go to a landfill.

    It is far easier to clean up ocean surface, than it is to clean the volume and bottom.
    But what is really needed is to get nations to stop dumping their trash into the oceans. China and Viet Nam ( surprisingly ) were shown to have done the vast majority of the ocean pollution. Rather than keeping cleaning up, we need to get ALL nations to stop dumping.

      40% of the trash in the Pacific enters from a single river: The Changjiang (Yangtze River) in China. 400 million people live in the Changjiang watershed.

        Where does the plastic come from though? A lot of it is western waste that was exported to be "recycled", but got dumped instead.

        China passed a law in 2020 aimed at cleaning that river up. Among other things it bans all dumping, chemical plants within 1km of it, and the use of highly polluting watercraft.

          I went to Kauai a few years ago, and 99% of the plastic trash on the beach with identifiable writing was from Asia.

          China has very few dissidents. Instead of protesting laws, they just ignore them.

      Agreed -- removing what's there is only half the problem, but good on Slat and his team for *doing something* about GPGP. It's on all of us to manage our use and disposal of plastics. As with almost everything else, there are tremendous benefits and equally horrendous consequences to plastics.

    It's nice and a positive start, but that is only a fraction of a fraction of what was added to the ocean in the same period.
    • The essential problem with the world drowning in plastic refuse is that the stuff in general falls outside the natural process of organisms to disassemble discards into useful material to rejoin in natural processes. There have been discoveries of some forms of life to decay at least some of the plastics and probably an ultimate solution will be to encourage these processes so they will automatically return the plastic molecules to interact with normal decay without human supervision.
  • Finally, some more work happening on the kind of scale we need to make a real difference. Bravo!
    • sorry but that is not on a scale that will make a real difference. They would need to be doing more than 100,000 times this amount to just break even for what goes into the ocean each year let alone make a real difference. It is a nice and anything pulled out is a positive, but the reality is this is like pissing on a bushfire. Will require a lot more scientific breakthroughs and human behaviour changes to have a real impact.
      • Your statement does not jive with the numbers. At the rate you're talking about there would be exponentially more trash then what they said is actually there. If they've done 1/1000th of the trash that is out there on the surface than your "100,000 times" number is wholly inaccurate. Not to mention it's akin to saying why bother to pick up the trash you see down at the park. People will just throw more trash on the ground. You pick it up because in the localized area that you picked it up, you're actually m
        • They have done 1/1000th of ONE area (ie the pacific garbage patch). The amount in the great Pacific Garbage patch alone is increasing at a rate at least an order of magnitude faster than their rate of collection.

          That's because you are mistaking what each is saying. The article/summary is stating 1/1000th of the Great Pacific garbage patch, the OP is talking about how much is pouring into the ocean each year. The Great Pacific garbage patch is merely one area that collects garbage and in this case it is only the surface garbage they are talking about.

          this might give you some idea of the scale of the problem. https://oceanservice.noaa.gov/... [noaa.gov]. That article talks about 8 million tons entering the ocean in just a si

      No. The collection net only skims the top 10 feet (3 metres) of the ocean to collect the plastics near the surface. Sometimes they catch dying turtles that are wrapped up in ghost nets, but they either try to cut them loose, or, if they catch live sea life, they release the entire collection net rather than bring it onboard. It means that some trash gets lost, but they figure they can finding the trash again is better than killing marine animals.

  • It's so easy to look at that number as such a tiny fraction... and to scoff at "It'll be gone if we do this 1000 times!", knowing that more and more is getting added every day. It's so easy to despair at all of this when it seems most of the world is willing to make things worse to save even a penny off their bottom line.

    But hey, these people did a thing and the world is a better place for it. Got to give them props for that, even if it doesn't feel like much.

    Every time there's an article about this guy Boyan Slat, and his decade old effort to *do something*, I already know what the comments section is going to look like

    1. But what about influx from China and Vietnam?!?!
    2. 100 tons? Meh. That's nothing.
    3. Better do X

    And if not all, large majority of those writing that never actually did anything even close to what this guy is doing, and improving on it every year. Aren't you ashamed you armchair smart asses, criticizing somebody actually trying to do something positive? Even collecting trash on the beach with a stick is better than doing nothing and bullshitting on the internet about people that do. If you're not ashamed, you should be, and I know how extremely egotistical tech people can be, so I'm sure you won't be, but will find another reason why you're right and smart.

    • I checked out their site and it seems they are using actual ships with actual people manning them to do the cleanups.

      I wonder if they can use automated ships with less men or totally automated to do this round the clock at all the garbage patch areas. May be more feasible nowadays with all the research on automated cargo ships, etc. Some even solar powered / other forms of green propulsion (yes I know sails are also green).

      If they can do something like that, running costs will be lesser and even if junk sti

    • If actually having "done" something was a prerequisite for discussing it, those people actually "doing" that thing would have precious few people to learn about it from in the first place. I don't know if you think your post is less egotistical than the thing you're complaining about, but it very much is not.
  • ASSUMPTIONS
    A - There's no more GPGP influx
    B - They keep working as efficient
    (they collected 4x what was expected)

    INPUT
    C - The started total was 100 MT (million of tons)
    D - They removed 0.1 MT/year (0.1MT=100 tons)

    MATHS
    Years to finish = C/D = 100/0.1 = 1.000 year = A MILLENIUM with no more GPGP influx and being as efficient as they were this year...

    Good luck...

    • You should follow the link "is starting soon" at the end.

      To simplify the math and save you the need:

      - Next gen is expected to be 10 times as efficient.
      - They want a fleet of 10 such systems.

      Once this is available, it's 10 years to clean the patch if it doesn't grow. If it does grow, it will take longer, but unless it grows at more than 50MT a year, that would certainly seem tractable. Even if it does, a few more systems should solve the problem.

    • You need to account for density and insolation too.

      IIRC the density is 1g per m3 of seawater. Sunlight breaks that down faster than 1000 years.

      So there will be a convergent point.

      It would be great if dipshits stopped throwing trash in the sea.

    The garbage could be burned on-site in plasma furnaces (to destroy any dangerous byproducts of combustion), with electrostatic smoke and ash filtration. The furnace could power the ships and machines. The CO2 could be put into the ocean. Perhaps the smoke and ashes would contain useful minerals. Any left over plastic could be made into "Garbage-Patch Dolls". Just kidding about the dolls.
  • .03 grams per square meter (100K kilograms over 3K square kilometers) collected.

    Either the collector is *very* efficient, or the garbage is *very* clumpy and they were able to efficiently find and harvest the clumps. A related question is the cost (including energy cost) of making and operating the collector (For making, assume mass-production cost, not the one-off cost of the prototype). Does the benefit exceed the cost?

    I think the efficiency will go down (perhaps rapidly) if this process is scaled up.

  • And only 100,000 kg of CO_2 were released into the atmosphere in accomplishing this.
