Ocean Plastic Waste Probably Comes From Ships, Report Says (afp.com) 97

Most of the plastic bottles washing up on the rocky shores of Inaccessible Island, aptly named for its sheer cliffs rising from the middle of the South Atlantic, probably come from Chinese merchant ships, a study published this week said. From a report: The study offers fresh evidence that the vast garbage patches floating in the middle of oceans, which have sparked much consumer hand-wringing in recent years, are less the product of people dumping single-use plastics in waterways or on land, than they are the result of merchant marine vessels tossing their waste overboard by the ton. The authors of the study published in the Proceedings of the National Academy of Sciences, or PNAS, collected thousands of pieces of waste during visits to the tiny island in 1984, 2009 and again in 2018. The island is located roughly midway between Argentina and South Africa in the South Atlantic gyre, a vast whirlpool of currents that has created what has come to be known as an oceanic garbage patch. While initial inspections of the trash washing up on the island showed labels indicating it had come from South America, some 2,000 miles (3,000 kilometers) to the west, by 2018 three-quarters of the garbage appeared to originate from Asia, mostly China. Many of the plastic bottles had been crushed with their tops screwed on tight, as is customary on board ships to save space, said report author Peter Ryan, director of the FitzPatrick Institute of African Ornithology at the University of Cape Town in South Africa.

    By analyzing the waste found in the rivers and surrounding landscape, researchers were able to estimate that just 10 river systems carry 90% of the plastic that ends up in the ocean.

    Eight of them are in Asia: the Yangtze; Indus; Yellow; Hai He; Ganges; Pearl; Amur; Mekong; and two in Africa â" the Nile and the Niger.

        • No you forgot to add the population of Africa, so that's 77%

          Also remember that a LARGE proportion of that pollution is because of jobs we outsourced to those locations. America *used* to be a lot dirtier, then standards rose and the dirty jobs got outsourced. America has the combination cheap goods, high standard of living and clean air ONLY because we paid someone else to be allowed to shit on their lawn, then we get to laugh at how their lawn is all shitty.

      • It's not supposed to be "impressive", and if the amount of plastic in the oceans has certain environmental consequences, the Earth doesn't do per capita calculations when deciding environmental impacts.

          The reason that plastic bags and plastic straws are so cheap and common in developing countries is partly due to them being in high demand in the West. If we switch to more sustainable products the price of those will fall too and it will be easier for developing nations to do likewise, not least since they are making a lot of this stuff locally anyway.

      The headline does not match the story.

      Headline: Most oceanic plastic waste comes from ships.

      Story: Most oceanic plastic waste IN THE SOUTH ATLANTIC comes from ships

      Since most plastic waste goes into the North Pacific, and most surface currents don't cross the equator, there is no way for it to reach the South Atlantic. Even plastic dumped into the North Atlantic, South Pacific, or Indian Ocean, would rarely drift into the South Atlantic.

    • That does not sound convincing.
      I live at the Mekong, besides "dirt" there is no real pollution in the river.
      If the Nile would be full with plastic, so would be the mediterranean sea, which it is not. The plastic waste is an atlantic and pacific problem.

      There are multiple metrics for the amount of plastic garbage in the oceans, including item count and weight. Interestingly, according [theoceancleanup.com] to The Ocean Cleanup [wikipedia.org], "When accounting for the total mass, 92% of the debris found in the patch consists of objects larger than 0.5 cm, and three-quarters of the total mass is made of macro- and mega plastic. However, in terms of object count, 94% of the total is represented by microplastics." Furthermore, "Fishing nets account for 46% of the mass" in the Great Pacific Garbage Patch.

      Based on the most common pollutants, it's not entirely clear that the plastic waste policy in the world is targeted at the most significant sources of the problem.

    • Yea you'll find the majority of it was coming out of rivers in which they "processed" recycling waste shipped to them from first world countries. I think their "processing" half the time involved just dumping or letting it fall into the river, not out of malicious intent, but just out of disorganisation, incompetency, taking on more than they can handle in the pursuit of $$$.

      The mess the planet is in today is because first world countries have been shirking their environmental responsibilities for far too

      (BTW, I crush plastic bottles and screw the cap on tight at home, so they'll take up less space in a landfill if they should somehow end up there instead of recycled.

      You should not do that. REMOVE THE CAPS.

      If bottles go to a landfill, they can be more reliably crushed flat with no cap.

      If bottles are recycled, the caps need to be removed because they are a different plastic (usually HDPE instead of LDPE), and often add color contamination. This adds pointless labor and expense to the recycling process.

      ALWAYS dispose of your bottles with the caps removed. This is true for glass bottles as well as plastic.

      if people on ships are just throwing these bottles overboard, why are they bothering to crush them to save space?)

      I wondered about that too. Maybe they are storing waste while in port. But in that case, they could just dispose of them in a dockside dumpster. But if they are just tossing them overboard while underway, there is no logical reason to crush them and screw on the cap.

      • Plastic Cap. Yeah, they are a different plastic and the bottles will likely go to a landfill when recycling companies sort them.
      • But if they are just tossing them overboard while underway, there is no logical reason to crush them and screw on the cap.

        This isn't about some douchebag standing on the deck, chugging his Deerpark water, and then throwing the bottle over the rail. These are big ships. On the passenger vessels, there are food service, bars, and room service operations all over the place. They use countless bottles of water, juice, soda, etc., as they serve. They temporarily store up that stuff all across the ship as bring it to central waste storage areas. Sounds like some of them like to avoid the costs of shore-side handling of those materi

      • They probably have to pay to dump trash when in port. And they can't dump until they get 200 miles out.

        Could be that they crush bottles for show. That way if they get inspected within someone's territorial waters, they can say they're doing everything right. They may even be taking extra trash to dump, because it's free.

      We go boating pretty regularly. Water bottles get crushed and then thrown in a trashbag. Since we are only out for 4-6 hours we just wait until we get to shore and then toss out the trash bag into the trash can. On a container ship it's probably cheaper (and certainly legal) to toss the trash bag overboard as soon as you are 200 miles offshore in international waters. Maybe less legal to toss plastic overboard but enforcement of trash laws offshore is 100% unenforceable. Also the average crew on a non-global scale containership can barely write their own name so educating them of the global impact of plastic in the oceans.
       
      Anyways, yeah it's super common to crush bottles for space on boats.

      • Yet there are only like 10 people on a container ship. And they tell us these ship crews dump more waste in the water than the billions people on land?
        And why would they crush bottles to safe space, if they just keep tossing them overboard in the next moment. People also need to safe space when they have to carry their trash from their home to the next river. This seems much more likely to me.
        • Do you walk all your trash from the living room to the garbage company's can, or do you put in a small wastebasket first, occasionally dumping it into a larger trashcan, and eventually dump that into the big can for the garbage company?

          Same thing on a ship. You don't walk each napkin or empty water bottle from the mess to the deck and toss it overboard before returning to the mess to finish dinner.

          • Well, I wouldn't say that they don't save space on ships. But people walking their rubbish to the next river are at least as likely to do the same.
            So I don't see how these researchers come to the conclusion that the waste comes from ships. Do they just assume that people live like them, and don't get how different life is for people in less developed countries?

        The obvious solution to this is to require ships reaching our ports to offload a reasonable amount of rubbish for their journey. If they were at sea for a month they should have a month's worth of rubbish to dispose of. A simple check by weight would be a good start.

      I think you're confusing your social media news feed with the reality. Yes, people get regularly crazy on stupid things, but no, the governments of countries all over the world (globally, not locally) do not take stupid decisions.

      Recycling was and is still useful. Throw-away plastic bags are being banned, replaced by re-usable bags. Plastic ware is being banned as well. That's where the world is going : less trash, less plastics burned or burried.

      But I'm not saying that is the situation in your local town. In particular this does not apply to the US where the government has no interest in driving country-wide policies about pollution, and where recycling is mostly relying on private business making profit or not.
