Second Attempt To Intercept Plastic Tsunamis In the Rio Motagua: Introducing Interceptor Barricade
HTML-код
- Опубликовано: 15 май 2023
- We're back in Guatemala for a second attempt at stopping one of the world's most serious environmental challenges with the new Interceptor Barricade - aiming to stop thousands of tons of plastic flowing from the Rio Motagua into the Caribbean Sea. Note: this is a computer rendering.

In 2022, The Ocean Cleanup trialed the Interceptor Trashfence in an attempt to stop the yearly flowing from Guatemala’s Rio las Vacas into the Rio Motagua and from there into the Caribbean Sea.
Despite initially holding back the tons of waste rushing downstream, our trial was unsuccessful, and most of the trash was lost. We’ve spent the last year studying what didn’t function as planned, and now we’ve deployed a new Interceptor with a new concept to finish the job we started one year ago.
With the Interceptor Barricade in place, we believe ultimately, we can have a major impact on ocean plastic pollution in the Gulf of Honduras and contribute to cleaner and healthier waters for Guatemala City and the wider national and international region.

I'm so glad you're trying again, it was so fun to watch last time.
The mass distribution of the trash might be the problem. The first design couldnt hold it, because it bent under the force and the new design even creates a weakspot at the endpoint of the barricade. Considering how dams work, you should consider a concave approach to distribute the force of the incoming weight over the whole barricade. Creating a stable construct that is easily assembled and disassembled might work with the concept of a leonardo brigde. At last, the waterflow has to be stable, so no plastic should block the flow. With a concave solution, the plastic is pressed down to the endpoints which could lead to a flow around the areangement. So the net-like damn should be quite wide. Extremely wider than the river itself.
There is even more to consider regarding the backpush of plastic when its shoved uphill on the river sides.
I would like to hear your opinion on my idea and the problems you discovered. Keep up your work!
You need to actively be removing the trash or it will block the fencing and burst the barricade. You can't fight literally hundreds of thousands of tons of water. Use a massive floating auger/screw conveyor with a porous shaft to get the trash to the shoreline and have a digger loader or a bulldozer to make space for the incoming trash.
Hi can you guys tie up with Indian government also .., I’m sure they will accept your technology and you’ll get paid well ..,
I have highly effective easy low cost solution for this problem.. interested to collab with u and wish make it success..
It feels so sick, that this has to be done, just because people/the industry are throwing their trash into the river or into the canalisation.
we should buy beverages in glass bottles instead of plastic, avoid paper-cups and plastic in general as much as possible. Buy more secondhand and refurbished things.
Guess what happens when those same people "migrate" to your country. They throw their trash on the ground and in the waters.
@@mm-hl7gh glass has its own issues. takes massively more heat/energy to make a glass bottle than plastic ones sinc eit has to be heated to 2000 degrees.
@@ge2719 and yet we used to use glass all the time. And it's like infinitely recyclable.
@@ge2719 only for the first bottle, the bottle after can be reused, plastic had to be melted over and over
Sense I saw the trial from last year on this river, I’ve been super excited to see the next trial, both to see what was learned and to hopefully see all of that trash stopped from falling into the ocean. So excited to see or hear about how this worked!
Already removed 1,5 million kg out of this river by the interceptor! Amazing achievement!!
It's always exciting to see an update from you, OC! Looking forward to the data from the Barricade.
One of my favorite youtube channels around! Love your work I wish yall best of luck!
I hope you can come to the Philippines too. Pasig river is one main river that traverses the Capital City Manila and it is littered with trash that goes out to Manila Bay.
there must be alot of ignorant and dumb people in philippines then. here in schwitzerland we can drink the water from the rivers, think about that.
Have you tried protesting to your Government to sort it out?
The plastic problem will not disappear within the next decades, as people are still not caring much about the impact their behavior has on the environment. But I just love to see you guys come up with attempts to fight the plastic flood, either on the oceans, the bigger rivers or even somewhere in the middle of a country like here in Guatemala. Thank you!
The Ocean Cleanup crew are a force of nature!
i appreciate the work you guys are doing
would love to see any on-site video once it is installed, see its effectiveness at work
This is so beautiful to see I really hope you succeed!
Its fantastic ! This is such a great news ! Many people are doing very good things. Thank you for saving Nature and the World 🌏🌎🌍🌏🌎🌍🌏🌎🌍🌏🌎🌍🌏
The barricade needs a horizontal moving conveyer belt across the front, to move debris onto shore as it piles up, to unload the barricade. If there's no power and no solar option, maybe a water wheel driven by the current could move it. Unless the cost and complexity wouldn't be realistic for this case. This is a noble cause, great to see these guys doing this work!
Great idea mate
I'd imagine that's why its at an angle, so the trash gathers on the shoreline to be collected. A conveyor would need a lot of force to move itself and the pile of trash and is likely to fail if it gets stuck in one place. It would be better to install baffles which push individual piece of trash along the barrier towards the shoreline.
@@daveythedave5612 I think the challenge is the amount of trash is enormous. They have another video somewhere when the trash actually comes down the river, there is soooo much trash. When it starts piling up, the force of the water starts washing the trash under the barrier. Trying to build a barrier that can hold that force indefinitely must be near impossible. To me it seems the only truly workable solution is some method of clearing debris from in front of the barrier to unload it. I don't think angling the barrier is going to be enough.
I'm thinking like a big funnel or multiple medium sized funnels (like a cement mixer) that moves the debris from the shore line to a ditch for later pick up. Not sure how it'd be powered though. Maybe with like a water wheel or something.
They have great engineers working on this. I am pretty sure they know what they're doing and that there are good reasons for not implementing a conveyor-belt here.
The proposed conveyor-belt solution would be heavy, thus not easy to keep afloat. But, most importantly, it most definitely would introduce significant reliability issues. And an unreliable solution is expensive to maintain. The Ocean Cleanup has to be monetarily efficient to achieve as much as they can.
They probably went with this angled solution (after a lot of mathematics, simulations and even real live trials went into it), because it is affordable, simple, modular, (relatively) low maintenance and uses part of the forces pushing against the barrier to move trash to the shore where it can be picked up.
It might not be ideal and will probably need further improvement, but I trust the team that - based on the data they have and the limits they have to work within - this is the best solution.
After seeing how the first prototype worked, and what overwhelmed the barrier in terms of sheer quantity and weight of trash+Water, I thought: what if it was possible to utilize the power of the current, and the weight of the trash pushing on the barrier? It made me wonder if there's a way to redirect this force to actually help push the trash off to one side, OUT of the river and onto an "off-ramp" of sorts... In a way I picture the trash being filtered back from the current, and directed towards one of the shore-lines. At the tail-end there would be a gently upslope off-ramp for the trash to move up from, and out of, the river, and onto a dry land storage plot where there could be either containers (with ability to drain off inevitable water that remained in compartments of the trash), or another means of initially processing the trash for recycling or what-have-you.
I would imagine the difficulty would be in developing a shore-based collection system that would be able to adjust to the variability of water levels in the river-though the video suggests there's a dam further downstream, so the area being studied might be a reservoir where water levels can be managed effectively.
As for getting the debris out of the river, the easiest and obvious solution is a scooping conveyor belt, that the debris is funnelled into and that could carry it up to a collection/sorting area on shore (well above the 100-year flood level of the river/reservoir). I would imagine, depending on the season, there might a lot of plant material-downed trees and the sort from heavy rain/hurricane flooding-brought down river from upstream, so the conveyor system would have to be able to handle that material as well as the routine garbage.
i was thinking the same thing without the part of getting energy from it but that would be smart but extra.
But unless that first barrier has 20 yard poles holding it in a ground of cement this 2nd attempt will look the exact same as the first. this simulation failed to show how much trash will actually be getting clogged and also how the barrier would react
Offloading garbage seems necessary. You cannot build an infinitely strong barrier that can keep up with all the increasing normal force of the trash that is piling up against it. Maybe that explains why the barriers in the simulations are slightly tilted.
I was thinking the same, like based of the old train cattle guards. so it would all be pushed up and to the sides for excavator's to start removing or something. just my 2c
yeap agreed, a basic barier still requires the trash to be manually scooped out and does in a timely manner to not overload the barrier, what about a divergent side river that gets shallow and shallow, with something smooth on the bottom like a concrete pad so bulldozers can just scoop the trash up off the concrete pad as the river pushes more and more up the divergent river using the said barriers? Or a river based or solar based paddle wheel or converor belt to push the trash into skips like the current interceptors
We just randomly found your channel watching your first try video. This is amazing work you’re doing. It’s almost incomprehensible how much garbage that one river pumped out. I don’t subscribe to many RUclips channels but I’m subscribed to you now. Keep up this great work. My eight year old daughter, Savannah, wants me to tell you this: ‘Thank you, thank you, than you, thank you!!!!!’
Good luck with the one guys. Fingers crossed it can withhold what the first one couldn't. Keep it up. you're all making a difference.
Wow, I'm so impress by everyone's efforts involved.
I know it must be so emotional to be able to choose what place gets serviced first,
time is of the essence💯
wow! Great trailer. I cant wait to see this in action!
The only company worth donating to. Thank you for all that you do, OC!
So excited to see the next iteration of the plan! We're all rooting for you!
Thanks for all your hard work
So basically the first barrier is designed to handle the onslaught of plastic but is leaking slightly while the 2nd barrier is designed to catch everything but can't handle the massive onslaught.
Am i understanding this correctly?
The first time they tried this, they only used one Barrier and it broke under the enormous pressure of the ridiculous amount of trash. I think you are correct and the idea is to split the load. I just hope they make them strong enough this time. Also a way to remove trash from the barrier quickly would be good.
Unbelievable work being done!
I am in awe of your tenacity and ingenuity! Question: Could your barriers channel the garbage into an extraction conveyor located on the river bank which feeds the trash into containers that can be hauled away much like the Interceptor? I’m sure that you have engineered an extraction phase but it seems to left out of you video.
LOVE the work you do!
Pity so many Governments DIDNT DO ANYTHING ABOUT THESE DELUGES IN THE FIRST PLACE!!
Has anyone thought of educating the villagers about how to deal with trash?
I think this is a great design. Once the plastic is trapped, how is it collected? would a collection area similar to the 002 be helpful? Since these communities are still developing waste management systems is there a way to work on those systems with them? I believe you are doing a fantastic job of working to stem the tide of plastic to the ocean. We just need more companies like you!
Truly Amazing! What an engineering feat! Can't wait to see videos of Ocean Cleanups aggressive river Program! Thank you Ocean Clean up for "Not Backing Down!"
Thanks Oc 👍
Cool. Good to know!
I have been waiting all year for this
I am so proud to be a supporter! It will be fascinating to see the new system do its work.
I would also highly suggest a mechanism to simultaneously move/clean the trash from barricades to prevent over spillage and also prevent them from additional damage.
Amazing work, wish the project every success.
Yeah, now you're getting there. Much better approach. Anxious to see if it will hold this time. Two barriers. Excellent.
Thank you for making a difference ❤
So excited to see it in action!
Looks great. Two-boom or multi layered approach. Just keeping going. 💯🔥💪
sick you guys are sick!!!!🥰 so stoked to see this in action - insane amazing work!!!
thank you !!
Fantastic Work Ocean Cleanup!!!!!!!!!!!
cant wait to see how it turns out.
If this fails, then take the capture net that you developed for System 002 and attach it to the middle of the Trash Tsunami barrier. That way, the force that would be overtopping or knocking down the barrier can fill up the "trash capturing sock" instead.
You can always make a bigger "sock" or deploy two "socks" or have two or more staggered barriers that each use the Tsunami to fill up more "socks, if you need to. And if the socks can be tied at the end, and the barrier is knocked over, with the trash captured inside the sock/s you get to contain some of the trash.
Yes, I was thinking of something like this too. But remember they are just starting to see what is possible, in testing phase first.
Im so excited to see if this works...I have been looking forward to the attempt!!🤞🤞🤞🤞
So excited!
Doing an amazing job guys!
It will be very interesting. After the last test I suggested a series barriers with decreasing mesh sizes so that they don't have to take the whole load. I hope two will be enough.
There needs to be a system to clear the trash to the sides where the barriers are stronger and to allow flow through. Otherwise you end up damming the whole river and barriers will fail.
Good luck with the new trials
❤BRAVO well done Team!! 🌷🌷
Looks promising! Good luck warriors!
Angle the interceptor from the cliff/steep side of the river to the beach side of the river. Make the angle as long as possible so it is somewhat self-cleaning and will push all the trash/plastic onto the beach side of the river.
Right on!

GRACIAS!!!!!!
I commend you for the effort you are making. Someone is doing something about it, and that is you. Guatemala's politics are down the drain, and all government officials care about is how much I am making of this deal. I hope you have the financial support you need to continue this effort and hopefully, the Rio las Vacas and Rio Motagua won't be so contaminated someday.
Hope you guys get more funding and can ramp up production and testing of these various platforms. Every government in the world should be part of funding this great initiative.
Whever did this simulation. I am super impressed. That ain't easy.
Extraordinary!! 😀😀
Interceptor barricade - Guatemala project is an example of keep trying until it effectively works..even when everyone tells it is impossible! Massive congratulations @theoceancleanup ❤
Go forth, heros!!
Great! Waiting for real video and testing!
Love your work 🙌💪♥
I hope this time it will work! Good luck!
Huray! Keep it going, yeah!
Nunca duvide de um ser humano. 👏🏼👏🏼
Im been waiting for this, sinces their last video. If this works it will be BIG.
Good luck! :)
amazing!!
it looks so cool, i hope it works now. much respect.
Will this be translated into Spanish? Actually, have you considered separate channels for different languages based on what region you're operating in?
Amazing innovation - can they be fitted with river turbines and solar panels to run extractor belts to bins along the side of the barricade for more effective extraction without need for staff there 24/7?
Ok, I read the article too. How does the trash actually get removed from the river? Excavators from the shore it says, but the geography seems to make that difficult with the slopes involved, and probable lack of roads and infrastructure available to support the task?
Good luck! 🤞
It's like you need a continuous conveyor system, running perpendicular to the water flow and across the width of the river, then feed that onto a conveyor that is that flat to the ground to pull it out of the water system and to keep your "net" always catching stuff, while reducing the water drag load on all the captured trash
Nice, I like the extra layer
Awesome. Would love to see this in China and India area. (Since they are approximately 90% responsible for the pacific garbage patch)
Nice simulation in the holo deck. Quite curious how good that will work in old reality.
You have not seen the previous ones?
@@markae0 I have. Is was quite a disaster. It was clearly too brittle for that massive wave of plastic waste. I liked that they did not want to give up but come back with a new approach. Not giving up is 3/4 of engineering.
@@thankyouforyourcompliance7386I wouldn't call previous work a disaster but a learning experience.
Oh nice!!!!
How do you plan to collect the plastic? Great Job!
Does this prototype take in account side erosion?
I remember the first attempt that was where some of the major problems came from, besides of course sheer amount of it.
Yes, it seems wonderful design. We have to let the water flow instead of resisting it. Nice, if two barricades is not enough, why three, four layers, until the trashes stop!!! Good thinking, great concept!!
Great!
Cant wait so see it in action! And how is the removal of plastic organized?🤔
Thank you for not giving up. Maybe it needs 3 or 4 catchments along the river to catch all that debri.
keep going! please don't give up.
I would imagine once you get enough bottles stacked up, the current of the water going underneath the barricade is going to suck a lot of them underneath and not just through the cracks. One solution might just be to have like 10 of these set up at fairly large intervals. You probably also need a way to remove the bottles as they're being held up. maybe like a shore based interceptor with the conveyer belt system or something.
Hoping everything goes according to plan. Thank you all for caring & trying!
Good luck! I hope it works!
Nice! Give us updates about how it's performing.
Need to put these things all around the US we are out of control polluting!
A country as rich as the US should have the resources to stop people from polluting. Prevention is always better than cleanup.
I don’t disagree, but where do we have rivers with tsunamis of plastic?
@ajlguitfiddle LA, New York City, Houston TX ever seen what it looks like with all the homeless? Ever been in Houston after 3 inches of rain! You can't see the water, it's all plastic floating in the surface in the harbor !!!! Rivers everywhere are flooding g the ocean with plastic! Ever see all the dead birds along the coast of the US and dead birds open them up and their stomachs are full of plastic !!!
Crazy that its come down to stuff like this. Hopefully next time it works
I am working on a ocean bound plastic renewal recycling startup in mumbai , india, would love to connect with people working on similar projects and similar startups and companies
I would also give the barricade of the first try another thought. But then don’t fight the water-forces, make use out of it. You can see that the water is heavier than the plastic and wants to get down, by doing so the plastic is pushed up. Guid the plastic up and away / out from the river. Build the barrier with an angle of attack / diagonal, this way new plastic is pushing, propelled by the water-force, the old plastic out. Also you’re making space for more plastic to come and you take the stress out of your barrier. Just need to see where to get a plastic dump field, which can be filled up temporarily with all that incoming plastic.
Let me know what you think!!
And then what happens after it builds up ? How do you get it out ?
I'm really curious to watch it in action
heck yeah! if you stop any significant part of the trash thats a win.
When can we see the real video of this project?
Wow awesome guys i camt wait to see it in progress. Is there going to be a method for real time trash removal? Or is this too dangerous? I do wonder if the weight will be ok this time. I noticed you are spreading the dam out as long as possible which seems like a logical solution. What other improvements have been made?
I read the article and it is a facinating design. I cant wait to see it in action
badass
I think you need to dig a rubbish collection pit at the lower end of the barrier (but slightly up stream) so that as rubbish builds up on barrier one it travels along the barrier and fills it. Reducing the weight the weight the barrier is holding and easier to empty.
props to the houdini artist
I think you guys should strongly consider processing the waste with pyrolysis and make it into usable diesel fuel to power your machines and fleet vehicles
Wow nice job, pity that it appears you need higher walls or a discharge system once it hits!
