'Great Pacific Garbage Patch' Can Be Cleaned Within 10 Years, Says Ocean Cleanup Project (yahoo.com) 110

"Six years after sailing out of San Francisco with the ambition of developing the technology to rid the world's oceans of plastic, The Ocean Cleanup returned to San Francisco with the knowledge and know-how to relegate the Great Pacific Garbage Patch to the history books," according to a new announcement from the group.

As the Los Angeles Time describes it, "After three years extracting plastic waste from the notorious Great Pacific Garbage Patch, an environmental nonprofit says it can finish the job within a decade..." Twice the size of Texas, the mass of about 79,000 metric tons of plastic floating in the Pacific Ocean between California and Hawaii is growing at an exponential pace, according to researchers. At current levels, the cleanup would take a decade with a price tag of $7.5 billion, the Netherlands-based Ocean Cleanup said in a press release, announcing the group's intention to eliminate the garbage patch entirely. However, computer models suggest a more aggressive approach could complete the job in just five years and cost $4 billion.

The cleanup vessels deploy enormous u-shaped floating barriers to funnel trash toward a focal point where it can then be loaded aboard and brought to shore... In their three years at sea, the Ocean Cleanup vessels have removed more than a million pounds of trash, representing 0.5% of the total accumulation. "We have shown the world that the impossible is now possible. The only missing thing is who will ensure this job gets done," said Boyan Slat, founder and chief executive of the Ocean Cleanup.

Project founder Boyan Slat said in their statement that "Today's announcement is clear: clean oceans can be achieved in a manageable time and for a clear cost.

"Through the hard work of the past 10 years, humanity has the tools needed to clean up the ocean. We have shown the world that the impossible is now possible... [F]or the first time, we can tell the world what it costs, what is needed and how long it could take. It is time for action."

Next year the group will take "a one-year operational hiatus," according to the announcement — to deploy a new initiative mapping areas of intense plastic accumulation to make extractions "more impactful."

        while most of it is plastic waste from asian rivers, a big part of that plastic waste was shipped from the us and eu (and falsely written off as "recycled").

        also, gp isn't fingerpointing, so why are you? he is actually quite correct: plastic pollution has a global impact, and we globally keep producing more and more plastic and disposing poorly of it.

        my first thought about this initiative was how long it would take for much of that removed plastic to get back to the patch. while it is indeed a good thing to clean the patch, our focus should be on rationalizing plastic use in the first place and hugely improving plastic recycling (which is marginal, regardless of all those green labels) and efficient and safe methods of disposal. unless we achieve that, we simply can't clean up that patch fast enough.

        • hugely improving plastic recycling (which is marginal, regardless of all those green labels)

          What is the problem with recycling? Is it a technical challenge, that we don't know how to recycle? Or is it a combination of economics and practical technology, i.e., that we know how to recycle but don't have a profitable way to do it?

          I believe the problem is the latter. The big criticism directed at the plastic manufacturers is that they have always known that recycling wasn't profitable and therefore would never happen without governmental push/support. Pushing recycling was purely a marketing gimmi

            It is economic.

            It's way cheaper to landfill plastic or dump it in a river than to recycle it.

            To make recycling happen, it needs to be subsidized. But that is dumb because the money spent on subsidies would be far more effectively spent on other things like wind turbines and solar panels.

            Plastic recycling is a fraud. It's not happening, and it isn't gonna happen in the future.

            We put our plastic waste on bunker fuel burning container ships and send it to Asia, where it's dumped in the ocean. Then we feel good about ourselves for being environmentally responsible.

            The solution is to stop using so much plastic crap in the first place. But if we continue to use it anyway, the best solution is to landfill it.

            I've cut most single-use plastic out of my life. It isn't that hard.

          • Fraud is the problem. A lot of recycling gets dumped directly into landfills from the recycling truck, or shipped elsewhere to be dumped into some other landfill or the ocean.

            [Setting aside the fraud issue, which is huge.]

            There is a significant technical challenge. Recycling aluminum isn't much more complicated than melting it down, letting most of the impurities (like label ink) burn off, skimming the dross off the top, then casting it into new billets. Paper and glass are almost that easy, too.

            Most plastics, especially thermoplastics like PETE (#1), can't be melted down the way metals can. Worse, they have a large number and amount of impurities, including intentional additives for color, strength, opacity, etc., in addition to the unwanted crap found in other recyclable materials. None of those additives can be cost-effectively isolated and filtered out. What this means is that the only practical way to recycle most plastic is to grind it up and use it as an alternative to wood for things like benches, decking, and whatnot.

            IMO we should stop thinking of plastic as recyclable, and concentrate on reuse. For example, our local recycling takes any plastic with a numeric marking, 1 through 7, but prescription bottles are explicitly not accepted. They instruct us to throw those in the trash. That's often more plastic by weight into a landfill than the weight of the medication it contained! OTOH, there is no reason other than profit that those bottles, mostly made of polypropylene (#5) couldn't be washed, sanitized, and reused, maybe dozens of times.

            Another example is bulk consumer products. Again, there is no reason other than profit that, say, liquid laundry detergent couldn't be sold like gasoline: Bring your own bottle, fill it, and pay by the liter. Liquids like milk are tougher for sanitary reasons, but could still be practical. In my ideal world, the only legal single-use plastic packaging would be for medical supplies and other life-critical applications.

            • IMO we should stop thinking of plastic as recyclable, and concentrate on reuse.

              While I agree, I don't think the answer is to recycle plastic. The answer is to replace plastic with other substances such as glass, metal, and biodegradable bioplastics. The problem is that plastic is so cheap, and companies go for the cheapest option.

              What's needed is intelligent regulation. While it might increases prices a few pennies, in truth, it probably lowers the long term cost. Typical of corporations, they are

            Recycling isn't even a technical challenge, hasn't been since the 1970s. It's a financial one. You can pump new plastic feedstock out of the ground for almost free (oil). Recycling is competing with almost free. Good luck with that.You could reduce the cost of recycling by 99% and it would still be twice as expensive as pumping new stuff out of the ground. There's an ocean of it under 20+ countries.

      Best way (with current technology) to get rid of this kind of (random and dirty) plastic is to burn it and generate energy from it. Obviously taking care of toxic fumes while doing it. It is pretty much oil in solid form. There are plenty of locations around the world that do this already, so you just need to deliver the trash to one of them.

      • There are many good reasons why we shouldn't burn plastics. Here's just one of them, some plastics give off extremely toxic & persistent dioxins (Think Agent Orange kind of toxic) when they're burnt: https://en.wikipedia.org/wiki/... [wikipedia.org]

We simply need to produce & use less plastic; I mean reduce it drastically & make the manufacturers pay for the somewhat complex & difficult safe disposal.

Also what you eat, it seems likely you'll get fewer plastics from food you've cooked from ingredients (meat, vegetables) than you will from a microwave TV dinner (is that phrase still in use?) that is microwaved in its plastic tray.

      Watching some of their videos, it seems like most of the plastic is high quality and high value plastic from the fishing industry. They were sorting it right on the ship, and much of it was valuable enough they could sell it to recyclers. I also think a lot of it was nylon (maybe?) and there's actually a new discovery that uses a catalyst to break down nylon within minutes, and into a form where 99% of it can be sold to plastic manufacturers. In fact the article said it was more valuable than virgin plastic because manufacturers prefer recycled material for marketing reasons. For the rest of it, they just bury it in landfills.

    Almost all of the plastic in the ocean comes from just ten rivers [scientificamerican.com]. Eight of those are in Asia, two are in Africa. As long as those countries continue to use their rivers as unrestricted trash and sewage dumps, there is only a limited benefit to any serious clean-up.

      False! This is an example of how scientific reporting shortening summaries has led to a completely incorrect and unfounded conclusion in the minds of people. That Scientific American used this article as a source: https://pubmed.ncbi.nlm.nih.go... [nih.gov] the conclusion was that almost all plastic in the ocean *coming from rivers* comes from just 10 of them.

      The entire study was based only on plastic movement down rivers. It did not in any way shape or form analyse the source of plastic in the oceans beyond rivers.

      Yes cleaning up rivers is important. There are additional studies that show some 70% of plastics is land based. The remaining 30% of plastic in the ocean comes from within the ocean (e.g. discarded fishing nets). Additionally from land based sources a not insignificant portion is coastal rather than river based rubbish.

      But still we need to clean up rivers. If you clean up those 10 rivers you are well on the way to solving maybe 1/3rd of the problem, after you discount the rubbish reporting (pun intended) of scientific media.

Because the problem of plastic waste entering the oceans was being enough that the EU imposed a block wide solution. Just because that person on the other side of the wate

    • That link says "more than a quarter of all that waste could be pouring in from just 10 rivers" not "almost all"
    • As long as those countries continue to use their rivers as unrestricted trash and sewage dumps, there is only a limited benefit to any serious clean-up.

      Unsurprisingly, they have considered this and have programs to address this. https://theoceancleanup.com/te... [theoceancleanup.com]

    If Bezos, Musk, Gates, Buffet, etc. want a measurable impact for their philanthropy - this is a no brainer they should fund. It is also right up the alley of something the Gates Foundation would back.

      What would be the measurable impact? Removing tons of plastic from the oceans is a good thing but you can't exactly tie it to lives saved or improved. The research seems to still be out on the actual impact of microplastics in the food/water supply.

      • There is ample that plastics are harming ocean ecosystems.

        Many of the projects funded by charitible organizations have nebulous impacts. It's one of the areas the Gates foundation prioritizes very highly... that the money spent has measurable outcomes with progress that can be tracked.

        The impact of this work is immediately quantifiable and measurable. That should make it attractive to these organizations.

    This just sounds like unrealistic promises from a nonprofit in order to stimulate fund raising. They haven't made a dent in the problem in 6 years, they are going to take a year off to improve logistics and technology and then they will complete the job in 9 years? While the world adds ever more plastic to the problem? They should tell people their gifts will get them straight into heaven while they are at it.

  • ... keep filling it up again.

    Just sayin'.

  • "is growing at an exponential pace" - what's the growth rate? 0.001% a year growth is a lot different than 10% a year growth which is a lot different than 100% a year growth.

    Also, exponential growth with a high-but-not-sustained growth rate isn't that impressive: We saw that in COVID, where active-case rates were on track to double every few weeks but that high growth rate didn't last very long.

    • If I have 20n^2 + 100 and simply n^2. We just call it a growth rate of O(n^2) for suitably large amounts of n.

      The cynic in me feels that it doesn't matter much what the initial conditions or even the coefficients are for this exponential growth rate are when we typically wait 30+ years before doing anything about environmental problems.

      Is it actually exponential? I doubt it. Maybe it's something like n^1.001 ?
      (I didn't bother looking up the research, I was hoping someone would post a summary and save me the

  • Yeah, it's a pain to trade them out, but the reusable part is a huge plus. When companies externalize the responsibility for managing waste packaging materials, you get "Great ________ Garbage Patches"
    • I prefer milk bags. You reuse a pitcher, often for decades. And they weigh less and save quite a bit on transportation and processing. They use a fraction of the plastic that a plastic bottle does, and they simply fold up into your waste basket instead of taking up a lot of space. Theoretically you could make a compostable version of the bag as it only has to exist on the order of the shelf life of milk.

  • Since the vast majority of the "Great Pacific Garbage Patch" is plastic from China, then maybe THEY should clean it up? Let's not forget that, to this day, simply hauling huge barges of trash out into the ocean and dumping it overboard is still one of the most common methods of garbage disposal in China. Dumping garbage into Chinese rivers that flow out into the ocean is also very high on the list...
    • I guess it's a matter of levels of development - we did that for a LONG time for various US coastal cities, such as NYC. Maybe we still do, I dunno.
  • What about all the ecosystems that have built up around the plastics?

    "Discovery of a thriving ecosystem of life at the Great Pacific garbage patch in 2022 suggested that cleaning up garbage here may adversely remove this plastisphere"

    A lot of sea life needs structures to thrive. We're building them homes.
