Giant Trap Deployed To Catch Plastic Littering the Pacific Ocean Isn't Working (cbsnews.com) 199

In September, a nonprofit deployed a multimillion-dollar floating structure designed to corral plastic debris littering the Pacific Ocean. But, according to CBS News, the 2,000-foot-long structure hasn't picked up any plastic waste. Slashdot reader pgmrdlm shares the report: A floating device sent to corral a swirling island of trash in the Pacific Ocean between California and Hawaii has not swept up any plastic waste. But the young innovator behind the project said Monday that a fix was in the works. Boyan Slat, 24, who launched the Pacific Ocean cleanup project, said the speed of the solar-powered barrier isn't allowing it to hold on to the plastic it catches. The plastic barrier with a tapered 10-foot-deep screen is intended to act like a coastline, trapping some of the 1.8 trillion pieces of plastic that scientists estimate are swirling in the patch, while allowing marine life to safely swim beneath it. The garbage patch isn't an island and it's even difficult to see with the naked eye, "60 Minutes" reported in September -- it's a vast soup of floating debris, much of it tiny and below the surface.

      This little more than a "smart" driftnet. It's not a surprise.

      the problem with actual driftnets is that they have a lot of bycatch because they're designed to trap fish. Whales, Dolphins, Sea Lions, Sharks, etc are just victims. Now if you make a driftnet that is electrified, sharks will at least be repelled by it. Throw in some ultrasonic noises to make it sound like a giant predator, and it will scare the mammals away too.

      • I buy singles from costco, they have zero plastic between them. They're just sitting there.

    • As an alternative, let's try nutritionally enhanced growth of surface matting algae in the gyre. This will trap a lot of plastic, including the very small pieces, and at the same time sequester carbon. When it dies off as the nutrient is exhausted, the carbon and plastics sink to the seabed, ready to form more coal.

      Yes, this would probably also kill a lot of fish. But fish that have ingested plastic are the ones we don't want in the food chain.

      They don't need engineers. They need accountants: Someone who can explain to them that every $1 they spend filtering microparticles out of the ocean would be a hundred times as effective if spent to prevent the trash reaching the ocean in the first place.

        As long as this continues, it is absurd to send ships thousands of miles out to sea to strain a few microparticles out of the ocean.

          Of course that is the place to stop it. Doesn't mean you can't clean up the existing mess.
          • The existing mess will clean up itself. Plastic gets constantly degraded to smaller pieces, ultimately down to molecular level. The key is to prevent new waste from entering the system, and the best place to start is with the biggest rivers of garbage.

            • That will take hundreds of years. What about all the fish that are swallowing it right now?

                It's pointless cleaning up the place where all the plastic collects if you are just going to continue adding to it.
                We should ban the fucking production of plastic except for special circumstances, and also enforce stricter recycling rules, only 10% of plastic is recycled AT ALL, it should be 99% is recycled. Only after that is achieved will it be worthwhile trying to sift it out of the ocean. Fine people littering heavily and that money can be used to help clean up the ocean. Charge people more for every piece of plastic in their garbage (that they haven't even tried to recycle) and pay people who are recycling, when plastic stops entering our rivers and hence into the ocean we can look at cleaning up that mess. Trying to do it now is just a waste of money and resources.

        Absolutely this. So many scientist told this kid that trying to filter plastic from the ocean is literally the last item on the to-do list of actual useful things we could do to help this planet. Cutting off new plastics and trash from entering the ocean is as close to the top as you can get here. All that crowd funded money was a complete waste on tech that's not really been tested and could have been used on any one of the multiple ways we know to filter trash from streams. I give the kid credit that he wants to help out, but blessed if he went the completely opposite direction of anything that could be remotely considered within 500 light-years of the definition of useful.

        • I think it comes down the the misunderstanding of the garbage patch in the Pacific. Many people seem to think it is like a solid island or otherwise tighly packed area of garbage, but while it is many time above the levels of populution it should be, it is not exactly dense (1-2 plastic objects per football field).

    Both the plastic and system are being carried by the current. However, wind and waves propel only the system, as the floater sits just above the water surface, while the plastic is primarily just beneath it. The system thus moves faster than the plastic, allowing the plastic to be captured.

    The system consists of a 600-meter-long floater that sits at the surface of the water and a tapered 3-meter-deep skirt attached below. The floater provides buoyancy to the system and prevents plastic from flowing over it, while the skirt stops debris from escaping underneath.

    Everybody was so busy jerking each off that no one actually tried to see whether it would work.
