Glass bottles should be standardized so all you have to is clean the bottle and put a new label on it. If a company wants to have a cool different bottle, then they need to pay the cost for it to be recycled upfront.

This is fascinating, but I find myself wanting to learn more about why rounded sand isn't useful. I mean, I do get it - angular sand, not rounded, will "lock together" at a very tiny scale, increasing the strength of whatever you put it into (like concrete), but if we're melting sand for glass, why can't desert sand work for that? Time to go do a little research, hey! The big point though is exactly as you said - gaining a better appreciation for everything we take from the Earth is one very good way to start changing how we do everything.
Rounded sand doesn’t bind well in concrete. Glass sand (crushed glass) can be used in concrete because the pieces of crushed glass are rough and jagged.

Maybe you are as smart as this professor. But no beach are static. They either grow or recede naturally. Messing with it will almost always makes things worse. If not at your location, somewhere close, that is related. Trying to fix nature with a few thousand tons of glass sand is merely a drop in the ocean. Not even enough to make a difference.
This video was well done but I wish you would have mentioned some more top-down solutions since this is clearly a systemic issue rather than an individual one. What type of policies should people be asking their representatives for or organizing around? I appreciated the bottom-up solutions mentioned such as small-scale glass recycling which is definitely one part of the larger solution...but not mentioning the systemic problems that lay the foundation for this level of resource exploitation to occur and the potential solution for that part of the problem is really disappointing.

@@infinitemonkey917 There absolutely are policy solutions, even under capitalism! In the USA, policies such as the Clean Air Act, Clean Water Act, Superfund Program, Endangered Species Act, and so many others have led to incredible positive environmental change on a local and national scale. None of these acts would have been created if it weren't for grassroots environmental justice activists and local community members who organized and pressured their political representatives (ex. Lois Gibbs, Love Canal). The above policies are not perfect by any means and should absolutely be expanded, but they are clear examples of how to tackle a systemic environmental problem.

Shift from steel and concrete construction to wood and other plant-based materials. Many wood products can one for one replace concrete and metal construction. An added benefit is carbon sequestration.
I'm from pa. Back when everything used glass containers, we would recycle them. You'd get some change back for taking your empties to the recycle. Glass is 100% infinitely recycalable. We switched to plastic because it was cheaper. Then they tried to convince us plastic was being recycled. We need to switch back to glass but the plastics industry is so massive that by getting rid of it, who knows what may happen. Its necessary though
@@holeshothunter5544 Beer deteriorates from exposure to sunlight/ultraviolet light. Glass bottle or plastic; it's going to deteriorate. Colourless, green, or brown; it's only a question of rate. Store your beer in a light-free place until you're ready to consume it. Cheers.
Also I'm kind of alarmed at all the comments being about recycling, when the biggest problem is "we are using up finite resources at an alarming rate and something has to change". This is true of a lot of things, actually.
We are also using way more sand than it is recycled and sand is a finite resources. Note that not everything made from sand can be recycled due to contaminants and the inherent properties of the finished products it's self and even then recycling said product back into usable sand would involve consuming a lot of energy, water and you guess it... sand. With the ever increasing demand of semiconductor, the demand for sand is higher than it's ever been and the process of purifying those sand into usable raw material for semiconductor use takes incredible amount of space, energy and other resources.
In that last statement, you can either use less materials, or in start contrast to how the US operates, you can stop building low quality buildings which get demolished and replaced every 40 years, and instead build high quality solid and long lasting piece of architecture that will last for many hundreds of years like how we used to build buildings in Europe. It might use more materials now but over the long term it is far less wasteful
Wow. I wish I were about thirty years younger so I could start up a business like glass half-full. I had no idea this was such a huge problem. Thank you for this episode and pointing this out to me. Thank you Glass-Half-Full for doing something about it. 🍷⏳

The coast of the southern US at the golf and inland 400 miles is sand. That sand is 45,000 feet deep. And that's a fraction of the sand that exists. We're not running out of sand. Geology science vod would be more informative that watching political spin like PBS.

In the san francisco bay we have the exact opposite problem. Se we straightened out the river removing the bends as these would slow the progress of the water and therefore it would flood every wet season. But now all that sediment get dropped off near the bay. In the brackish waters. They have to go out there and dredge it every so often otherwise we would be building islands out there, which is of course unacceptable in the middle of important shipping channels. We use the sediment we dredge out there to cover landfills and raise ground in low lying areas then build housing developments on top of these. In fact most of Elk Grove was once a low lying wetlands area until we filled it with trash and then covered it with dredge effluence. Every once in a while a piece of old trash will float up in my yard. I remember one year I was digging around and found strange piece of plastic. Turned out to be Kermit the Frog's eye. LOLs
Very interesting video. I would like to share a childhood memory: In the 50's and 60's, when there was a construction boom in my country Greece, entire mountains were eaten away to make sand for building, leaving ugly scars on the faces of the mountains. These have been restored by now, some of them beautifully, but as a child, it made me feel really sad. Luckily, though my country has loads of sandy beaches, that kind of sand was supposedly no good for building due to too much salt content; thus beaches were saved, because we had a lot of mountains as well. I suppose we must keep an eye out for beach thieves!
So wait, if we need to consume less sand what do we replace it with? If the demand is there something else needs to take it's place. Otherwise sand will continue to be consumed until it's exhausted.
Is the glass sand not sharp? Also At 5.30 in the video a worker is shown sifting glass sand without a mask. Wouldn't breathing glass dust at work everyday be a problem?
A hidden note here; it had been in the back of my mind and this video brought it front and center. The amount of sand being used worldwide in concrete, has sequestered that sand for something like millennia, at least. This would be the largest depletive human use of sand, which recycling glass for sand can never overcome. Still, I think it is worthwhile, as the young lady from glass half full explains… In global struggles, every little bit helps!
I’ve been able to almost completely eliminate buying food products in plastic containers. If it doesn’t come in a glass jar, can, or gabled carton, I don’t buy it. Like someone mentioned, those glass recyclers need respirators. Good report, thanks.
A very sand poor area is Big Island Hawaii. Also no sand anywhere, even the beaches. Most are hard volcanic rock. The few sand beaches they have are course black sand and it only goes a few feet in the way, have to wear water shoes in the ocean
I had already heard of Glass Half Full. I think Business Insider did a piece on the company when they discussed flooding and inland floods regarding climate change and hurricane season and that sort of thing. Im eager to know it can help, but its not the main solution. We need to stop the hyper consumption of well, everything. I hope we can do better.
I just hope they take Health and Safety laws seriously --not even the laws themselves, employers should go beyond that and take proper care of their workers. Saying this because in a shot there's a worker with no mask right next to the conveyor with fine glass shards in the air just waiting to cut up their insides and ruin their lungs and eyes.
It’s always interesting to me that the solution to negative effects caused by humanity is more human intervention and attempts to be Mother Nature. It’s some degree of insanity tbh. Feels like a robbing Peter to pay Paul type of scenario.
we really need to start naming the problem, which isn't "humanity". indigenous cultures know how to manage resource usage, it's infinite growth capitalism on a finite world that's the issue.
don’t think indigenous participate in capitalize in the year 2023? People are the problem maaaan. You can’t blame simply the system if the system is created by and supported by a human. Humans are the problem and the fact you’re disputing this for some reason shows me that humanity will continue down it’s current path of self sabotage.
I feel like something died inside me today. A greening video showing that we used petroleum to turn sand into glass and as an answer to that were using petroleum to turn glass into sand? Am I alone here?
Glass sand tends to be unusable for construction/concrete in that its too “smooth” or slick to hold together. I think they found this out when they tried to use “Glassphalt” in NYC … the aggregate (glass) just pressed its way out. Concrete itself is now being recycled for new aggregate in new concrete.
🤦 Do you need people to explain things like you are a child? It's being reallocated which is destroying ecosystems. Human resource consumption, including sand importation so places like Singapore can extend their land mass over the ocean, creates an increasing market to take sand from one place/ecosystem to create another artificial land mass, and we are also using it in TONS of products.

I did hear abound sand shortage problem before, but it still surprises me. So that desert sand is not good for anything at all?, Not even for concrete production?! Also about the beaches restoration. If you shoot the sand from the ocean back to the beach, what happens to it that you need to bring it from inland after some time?, Certain points were not explained very well in my opinion.
When I saw the processing facility 4:11 , the first thing that came to mind was an old saying: "Don't breathe glass dust." Why don't they have any respiratory protection? The building doesn't look like it has any air filtration.
The one thing that they didn’t mention is, are they doing research to see if ground glass sand suitable for use in concrete? If the finest glass sand is good for recycling into more glass and the coarsest glass sand is good for beaches and wetlands restoration then couldn’t the municipal recycling programs fund themselves by selling those parts of the glass recycling and using what is left over in their municipal construction projects such as new sidewalks?
50 pounds of sand is $7 at a big box store. The video said about half of the glass sand was usable. So you would need to collect 100 pounds of glass bottles, ship it to the site, clean and process it, find someone to buy it (contractors won't pay retail). Minimum wage is $7.25, then you'd have to factor in the land, building, equipment, etc. We all know recycling is a losing game, this is just helping you put context around recouping the cost being infeasible. Reducing is a better effort. You might defray a small fraction of the total program cost.
I'm confused about how simple of the solution it sounds to take all the sand that we took out of the ground via machines to make bottles and glasses and cups and dishes and other glass things and figurines and decorative pieces. And take all that out of the trash and put it back in the dirt how you say it's not going to help or make that big of a different that's where all the same came from by putting it back I wouldn't think it would help substantially we're not doing it on a big enough scale. All Glass eventually gets broken very few of it hangs out except in Windows and glass tables but other than that all other glass usually gets broken and thrown away there's so many beer bottles at bars restaurants casinos people's houses. We need to do it on a bigger scale like Nationwide.
There may be a nasty surprise down the line from the long-term exposure to glass dust in the environment. I guess it would be much better to recycle glass as glass.
Can these people working with the glass recycling please get some safety breathing masks that fine dust floating about like that get into your body and causes severe health problems and damages the air sacks in your lungs. otherwise thanks for video

Or let the mississipi run its proper course. there LOTS of sediment being dumped at lake pontatraine outlet to the gulf. yet the coastal erosion is at the region by Atchafalya outlet to the Gulf. sadly, this would mean to go Game Of Throne and "Flood them all" but there just needs to be river discharge over there. idk why and how, but theres a reason why rivers change course every so often per hundreds of years. The Baton Rouge to New Orleans route is only economic, and while im from the Great BR area, water needs to alternate is discharge pattern. nature isnt set in a rigid order, it fluctuates. 1) oxbow lake 2) changes to its dischage routes and other beautiful randoms of water. source: just a kid who observed the rain on the window in a car. its meandering patter alternated depending on the intensity of the rain. always an S shape but its sometimes swerved to the right and other times to the left. i get it, engineers design for their desired end result, but they also gotta work WITH natural nature balance. texas has their barrier islands, but We Louisianaians gotta spend state and federal tax dollar to build up sand bars and barrier islands and coastlines that could be passively built up each year with river discharge sediment. yeah, i get it. the counter point is Economic Baton Rouge, Port Allen, New Orleans, and so many other cities along the current route would have a lower river. idk, cuz theres LOTS of moving parts going on. for 2023 the Drought is causing problems already and if my propsed idea were implemented it has SEVERAL short term human disadvantages. but im not a politician nor engineer so i literally dont even have the power to flood the folks of Henderson, Grosse Tete, Morganza, Lafayette, Butte La Rose and so on. (its a bit of rutal cities but still not cool to willfully flood them out) again, its to build up the coastline. barrier islands would save FEMA money on checks. idk. its just somewhat intuitive to me, why make humans work increasingly harder to yeild decreasing less results at increasing prices for something that nature does PASSIVELY. my biggest problem with my proposed idea, is the ethical implications and the economic casualties. deflating the very aspect of why the River Cities were founded in the first place. (cuz tbh im proud of being from a city where the biggest river of the US flows through) and kinda nose down Lafayette cuz of the puny Vermillion River or the nearby Atchafalya. but if you took a bottle of water and poured it down the window of your car, you would see that water MEANDERS. as such the consequences of binding the River to a this path means the discharge is not building the coastline up. which makes Hurricanes that much worse. since their enegry isnt buffered by sand bar barrier islands.
people need to remember the big infrastructure projects in the world today and in the future from sky scrappers, houses, roads we drive on all require cement/concrete-which requires of a lot of sand
Y’all have obviously never spent any time in Southern California, Arizona, Nevada. There are 124 square miles of sand in Imperial, Ca in an area called Glamis. That’s the same size area as Gaza. So trade. Cali needs your water, y’all need their sand. Make it happen
This is all the more sad knowing that glass is one of the few infinitely recyclable materials in existence. Glass recycling should be a priority 1 industry. The issue is concrete. We use way, way WAY too much of it for everything when there are better solutions and materials.
@@yyeezyy630 Depending on the project, structure, shape, uses, climate, geological location, etc., there are alternatives for all kinds of construction up to a certain scale. And I'm not even saying that we can't or shouldn't use any concrete at all, only that we should try to minimize the amount. But, as far as alternative materials, Wood can be used to construct multi-story buildings as high as 12 or 15 stories. Bamboo construction is astounding and can hold up for centuries. Brick requires concrete, but it requires way less per square foot. Stone is extremely structurally sound. Earth and adobe structures have stood for hundreds, even thousands of years. Steel and other alloys are alternatives. Sure, some of these may take more time to construct, and some of them may cost more; but, quick, easy, and cheap is what got us into the mess we're in on a multitude of fronts. Besides, not every structure has to be a bomb shelter with 18-inch thick cement walls. But, if you're actually that curious, just look it up. You'll get better information than from asking some random guy in the comments.
I got my first driver’s license by collecting glass soda bottles. It’s a shame our drinks aren’t glass anymore instead of non recyclable plastic. The glass it seems to me keeps drinks colder and are recyclable.
Two comments, hopefully redundant! 1. ¿Do you remember the story about bulk carrier ships taking sand from Scotland to Saudi Arabia? The sand in Saudi Arabia is from a dried up ocean, and therefore contains salt. The cost/quantity of water needed to wash the salt down to a level useful in construction was greater than the cost of shipping salt-clean sand from Scotland. 2. ¿Do you remember the California gold rush? The layer of sediment laid down in San Francisco Bay 150 years ago contains so much mercury from the gold works that this sediment must not be disrupted. ¿Did I get this right?
I understand the need for sand to make concrete and glass, but using sand to restore beaches seems like a waste of the sand. Sea levels are rising and hurricanes are getting stronger, so humans should be moving away from the coasts instead of trying to save them.
I think the misunderstanding here is that they're restoring beaches for human use. The way I understood it is that they're trying to restore environments used by wildlife. We're destroying their habitats, so we're trying to fix it. It's not the best solution, as they said in the video, it's just people doing what they can until a better idea comes along
I live in the US and yes, "recycling" bins exist, but what's in question is what happens to the material. I am given to understand that not much of it is recycled. I'm so convinced that there is in fact no plastic recycling, even though the propaganda says you should put it in the recycling bin, that I now routinely send all plastic toward my county's incinerator.
Glass bottles are the one thing that can be recycled without deterioration. Not doing it because we "can't afford it" is dumb. We can't afford to live on with our heads buried in the sand. We need to do the simple things, there are much more complicated challenges ahead than recycling glass bottles.
@@GenRN I suppose so, but naively I would think that wave breaking barriers could be more effective and longer lasting. Again - ‘naively’ being the keyword here
California is washing away. A woman went to the beach on fine day and sat under the cliffs in Del Mar. She was crushed death when the cliffs collapsed above her. The lack of sand caused the ocean, during storms, to carve out a nice place to sit on the beach. Then it fell down.
this story makes me remember the "recycling wars" (coined by a friend). 2 companies stole each others trash containers and/or contents because it was basically free money (the trash truck would drive through there anyway and trash was auto sorted up to 90% at the facility) and the "war" kept going for 2 years or so until thepolice and DAs got involved. in the end both sides paid fines etc. and not even a decade later they merged... funniest story I ever heard lmao
If you are going to inflate archaically, you should do so properly. "But" is a conjunction and "alas" is an interjection. They should be separated by a comma. There is really no scenario where they should go together, like this.
Also the building of homes so near the beach that happen so often in the US can and do affect, here at my country ever since we’ve been getting lots of Americans gentrifying our beach coast they’ve been illegally filling wetlands with beach sand which cause a huge problem in many ways these people don’t even care to understand…so building infrastructure should also consider if the location will unnecessarily make more use of sand by having to fill in the space completely while also destroying whole ecosystem that also protect communities from flooding
Ahh yes, PBS lecturing me AGAIN on a subject that could be foreseen DECADES ago BUT (thanks to Newt Gingrich defunding) PBS is just another network on the Capital Growth Train.
M-Sand is available, Recycled glass is available as substitute, coal mining waste and recycled concrete is another option. Four better options available and sustainable!
When I think of sand I think of the Sahara desert, the Gobi desert, the Arabian desert, the Kalahari desert, the Australian desert, the Arizona desert, etc. Perhaps it is a problem of vandalism or unregulated capitalism instead of "sand" scarcity.
Most of the Arizona desert doesnt have much sand. Sand dunes exist, but they're really mostly just down by Yuma on the way to the Gulf of California. Most of the rest is dirt and dust instead of sand
I didn’t realise the coastal erosion of Louisiana was so intense. And that’s with the reconstruction efforts… More people who think sea level rise isn’t real need to understand sea level rise doesn’t mean constant flooding (in most places), but it means receding coastlines!! That said, I do wish PBS with its reputation for accuracy would say “Queen of the UK” not “Queen of England”. I don’t even like having a monarchy, I wish we didn’t have one (I guess that makes me a republican, though not a Republican!), but the phraseology does minimise how important Scotland was in its history.
The problem is known for decades. Some countries have even passed Federal Laws to stop removal of sand from most river banks. This created another crime type but that is another story. We need to recycle more and find/create new building materials and techniques.
Okay, so where is all the sediment going that would naturally go to the mississippi river delta? It cant just be disappearing. Take it from whereever it is ending up and use it to rebuild the coast.
Glass bottles should be standardized so all you have to is clean the bottle and put a new label on it. If a company wants to have a cool different bottle, then they need to pay the cost for it to be recycled upfront.

With the ever increasing demand of semiconductor, the demand for sand is higher than it's ever been and the process of purifying those sand into usable raw material for semiconductor use takes incredible amount of space, energy and other resources.
How bad does it have to get for people to start stealing beaches....

In that last statement, you can either use less materials, or in start contrast to how the US operates, you can stop building low quality buildings which get demolished and replaced every 40 years, and instead build high quality solid and long lasting piece of architecture that will last for many hundreds of years like how we used to build buildings in Europe. It might use more materials now but over the long term it is far less wasteful
Wow. I wish I were about thirty years younger so I could start up a business like glass half-full. I had no idea this was such a huge problem. Thank you for this episode and pointing this out to me.
Thank you Glass-Half-Full for doing something about it. 🍷⏳
I hate sand. It's course, it's rough, it's irritating and it gets everywhere.
I've watched this channel for 2 years at least, and there seems to be consistent dumbing down of their content. The info, even the cadence and tone of the presenters speech, more and more sounds like childrens program.
Making less concrete and using hempcrete instead could really help. Less sand would be needed. Hemp can offer a ton of healthy alternative building material. Hemp crete and insulation etc
The coast of the southern US at the golf and inland 400 miles is sand. That sand is 45,000 feet deep. And that's a fraction of the sand that exists. We're not running out of sand. Geology science vod would be more informative that watching political spin like PBS.

I hope the workers in the glass recycling industry protect their lungs from that silica dust.
In the san francisco bay we have the exact opposite problem. Se we straightened out the river removing the bends as these would slow the progress of the water and therefore it would flood every wet season. But now all that sediment get dropped off near the bay. In the brackish waters. They have to go out there and dredge it every so often otherwise we would be building islands out there, which is of course unacceptable in the middle of important shipping channels. We use the sediment we dredge out there to cover landfills and raise ground in low lying areas then build housing developments on top of these. In fact most of Elk Grove was once a low lying wetlands area until we filled it with trash and then covered it with dredge effluence. Every once in a while a piece of old trash will float up in my yard. I remember one year I was digging around and found strange piece of plastic. Turned out to be Kermit the Frog's eye. LOLs
Very interesting video. I would like to share a childhood memory: In the 50's and 60's, when there was a construction boom in my country Greece, entire mountains were eaten away to make sand for building, leaving ugly scars on the faces of the mountains. These have been restored by now, some of them beautifully, but as a child, it made me feel really sad. Luckily, though my country has loads of sandy beaches, that kind of sand was supposedly no good for building due to too much salt content; thus beaches were saved, because we had a lot of mountains as well. I suppose we must keep an eye out for beach thieves!
So wait, if we need to consume less sand what do we replace it with? If the demand is there something else needs to take it's place. Otherwise sand will continue to be consumed until it's exhausted.
Is the glass sand not sharp? Also At 5.30 in the video a worker is shown sifting glass sand without a mask. Wouldn't breathing glass dust at work everyday be a problem?
Is river rock sharp? no. Is vocanic ash sharp? yes.
A hidden note here;
it had been in the back of my mind and this video brought it front and center.
The amount of sand being used worldwide in concrete, has sequestered that sand for something like millennia, at least.
This would be the largest depletive human use of sand, which recycling glass for sand can never overcome. Still, I think it is worthwhile, as the young lady from glass half full explains…
In global struggles, every little bit helps!
I’ve been able to almost completely eliminate buying food products in plastic containers. If it doesn’t come in a glass jar, can, or gabled carton, I don’t buy it. Like someone mentioned, those glass recyclers need respirators. Good report, thanks.
Others have said already, but: Wear feckin‘ masks if you don’t want to get sick and experience a slow and agonizing death.
"I don't like sand. It's coarse, and rough, and irritating, and it gets everywhere."

My city stopped recycling glass because it has mountains of glass that no one will buy.
I love he said he been at it for 6 years like it is alot people tried to warn about global warming in the 80s
A very sand poor area is Big Island Hawaii. Also no sand anywhere, even the beaches. Most are hard volcanic rock. The few sand beaches they have are course black sand and it only goes a few feet in the way, have to wear water shoes in the ocean
I had already heard of Glass Half Full. I think Business Insider did a piece on the company when they discussed flooding and inland floods regarding climate change and hurricane season and that sort of thing.
Im eager to know it can help, but its not the main solution. We need to stop the hyper consumption of well, everything. I hope we can do better.
I just hope they take Health and Safety laws seriously --not even the laws themselves, employers should go beyond that and take proper care of their workers. Saying this because in a shot there's a worker with no mask right next to the conveyor with fine glass shards in the air just waiting to cut up their insides and ruin their lungs and eyes.
Georgia has plenty of sand. We have sand dunes 30 miles inland from when sea levels were much higher.
It’s always interesting to me that the solution to negative effects caused by humanity is more human intervention and attempts to be Mother Nature. It’s some degree of insanity tbh. Feels like a robbing Peter to pay Paul type of scenario.
we really need to start naming the problem, which isn't "humanity". indigenous cultures know how to manage resource usage, it's infinite growth capitalism on a finite world that's the issue.
Oh so people?
@@zanerasmussen8889 are you dehumanizing the indigenous, or do you simply believe even the indigenous are capitalistic?
don’t think indigenous participate in capitalize in the year 2023? People are the problem maaaan. You can’t blame simply the system if the system is created by and supported by a human. Humans are the problem and the fact you’re disputing this for some reason shows me that humanity will continue down it’s current path of self sabotage.
They URGENTLY need to start wearing respirators around that glass dust!
If OSHA says it’s ok then it can’t hurt you
I feel like something died inside me today. A greening video showing that we used petroleum to turn sand into glass and as an answer to that were using petroleum to turn glass into sand? Am I alone here?
Glass sand tends to be unusable for construction/concrete in that its too “smooth” or slick to hold together. I think they found this out when they tried to use “Glassphalt” in NYC … the aggregate (glass) just pressed its way out.
Concrete itself is now being recycled for new aggregate in new concrete.
Sand is Sand
Stop the BS
amazing video!!! everyone is so talented!!!
Getting materials for construction is actually a problem for Constructors like me today.

🤦 Do you need people to explain things like you are a child?
It's being reallocated which is destroying ecosystems. Human resource consumption, including sand importation so places like Singapore can extend their land mass over the ocean, creates an increasing market to take sand from one place/ecosystem to create another artificial land mass, and we are also using it in TONS of products.

I did hear abound sand shortage problem before, but it still surprises me. So that desert sand is not good for anything at all?,
Not even for concrete production?!
Also about the beaches restoration. If you shoot the sand from the ocean back to the beach, what happens to it that you need to bring it from inland after some time?,
Certain points were not explained very well in my opinion.
Can you use wind-blown sand for coastal restoration?
Hey, y'all know what beach zombies crave for dinner? grrRRRAAAIIIiiinnnns!
When I saw the processing facility 4:11 , the first thing that came to mind was an old saying: "Don't breathe glass dust." Why don't they have any respiratory protection? The building doesn't look like it has any air filtration.
Can you turn desert sand into glass?
The one thing that they didn’t mention is, are they doing research to see if ground glass sand suitable for use in concrete? If the finest glass sand is good for recycling into more glass and the coarsest glass sand is good for beaches and wetlands restoration then couldn’t the municipal recycling programs fund themselves by selling those parts of the glass recycling and using what is left over in their municipal construction projects such as new sidewalks?
50 pounds of sand is $7 at a big box store. The video said about half of the glass sand was usable. So you would need to collect 100 pounds of glass bottles, ship it to the site, clean and process it, find someone to buy it (contractors won't pay retail). Minimum wage is $7.25, then you'd have to factor in the land, building, equipment, etc.
We all know recycling is a losing game, this is just helping you put context around recouping the cost being infeasible. Reducing is a better effort. You might defray a small fraction of the total program cost.

Stripping Midwest farmland in La Salle County, Illinois and in Wisconsin for sand is not a solution, yet it's happening at an unprecedented rate.
Not in Arizona. Please, take some. Every monsoon roads flood with sand, everywhere.
I'm confused about how simple of the solution it sounds to take all the sand that we took out of the ground via machines to make bottles and glasses and cups and dishes and other glass things and figurines and decorative pieces. And take all that out of the trash and put it back in the dirt how you say it's not going to help or make that big of a different that's where all the same came from by putting it back I wouldn't think it would help substantially we're not doing it on a big enough scale. All Glass eventually gets broken very few of it hangs out except in Windows and glass tables but other than that all other glass usually gets broken and thrown away there's so many beer bottles at bars restaurants casinos people's houses. We need to do it on a bigger scale like Nationwide.
There may be a nasty surprise down the line from the long-term exposure to glass dust in the environment. I guess it would be much better to recycle glass as glass.
@@eljanrimsa5843 well crushed underwater would contribute to (0) ZERO DUST. i would believe

Wonder if labels and stickers on the glass bottles have to be removed before the bottle is crushed.
Some places uses a hot bath for that before grinding up the glass
I think some places crush the bottles and put them through a sieve machine to separate the labels, but they also do something that washes the glass I think?
Or let the mississipi run its proper course.
there LOTS of sediment being dumped at lake pontatraine outlet to the gulf. yet the coastal erosion is at the region by Atchafalya outlet to the Gulf.
sadly, this would mean to go Game Of Throne and "Flood them all" but there just needs to be river discharge over there.
idk why and how, but theres a reason why rivers change course every so often per hundreds of years. The Baton Rouge to New Orleans route is only economic, and while im from the Great BR area, water needs to alternate is discharge pattern.
nature isnt set in a rigid order, it fluctuates.
1) oxbow lake
2) changes to its dischage routes
and other beautiful randoms of water.
source: just a kid who observed the rain on the window in a car. its meandering patter alternated depending on the intensity of the rain. always an S shape but its sometimes swerved to the right and other times to the left.
i get it, engineers design for their desired end result, but they also gotta work WITH natural nature balance.
texas has their barrier islands, but We Louisianaians gotta spend state and federal tax dollar to build up sand bars and barrier islands and coastlines that could be passively built up each year with river discharge sediment.
yeah, i get it.
the counter point is Economic
Baton Rouge, Port Allen, New Orleans, and so many other cities along the current route would have a lower river.
idk, cuz theres LOTS of moving parts going on. for 2023 the Drought is causing problems already and if my propsed idea were implemented it has SEVERAL short term human disadvantages.
but im not a politician nor engineer so i literally dont even have the power to flood the folks of Henderson, Grosse Tete, Morganza, Lafayette, Butte La Rose and so on. (its a bit of rutal cities but still not cool to willfully flood them out)
again, its to build up the coastline.
barrier islands would save FEMA money on checks.
idk. its just somewhat intuitive to me, why make humans work increasingly harder to yeild decreasing less results at increasing prices for something that nature does PASSIVELY.
my biggest problem with my proposed idea, is the ethical implications and the economic casualties. deflating the very aspect of why the River Cities were founded in the first place.
(cuz tbh im proud of being from a city where the biggest river of the US flows through) and kinda nose down Lafayette cuz of the puny Vermillion River or the nearby Atchafalya.
but if you took a bottle of water and poured it down the window of your car, you would see that water MEANDERS. as such the consequences of binding the River to a this path means the discharge is not building the coastline up.
which makes Hurricanes that much worse. since their enegry isnt buffered by sand bar barrier islands.
people need to remember the big infrastructure projects in the world today and in the future from sky scrappers, houses, roads we drive on all require cement/concrete-which requires of a lot of sand
If you have to build a levy to make a place habitable, then don't live there.
Y’all have obviously never spent any time in Southern California, Arizona, Nevada. There are 124 square miles of sand in Imperial, Ca in an area called Glamis.
That’s the same size area as Gaza.

This is all the more sad knowing that glass is one of the few infinitely recyclable materials in existence. Glass recycling should be a priority 1 industry. The issue is concrete. We use way, way WAY too much of it for everything when there are better solutions and materials.
Like what? I’m genuinely curious what this material is that doesn’t cost more and Is just as structurally sound
@@yyeezyy630 Depending on the project, structure, shape, uses, climate, geological location, etc., there are alternatives for all kinds of construction up to a certain scale. And I'm not even saying that we can't or shouldn't use any concrete at all, only that we should try to minimize the amount. But, as far as alternative materials, Wood can be used to construct multi-story buildings as high as 12 or 15 stories. Bamboo construction is astounding and can hold up for centuries. Brick requires concrete, but it requires way less per square foot. Stone is extremely structurally sound. Earth and adobe structures have stood for hundreds, even thousands of years. Steel and other alloys are alternatives.
Sure, some of these may take more time to construct, and some of them may cost more; but, quick, easy, and cheap is what got us into the mess we're in on a multitude of fronts. Besides, not every structure has to be a bomb shelter with 18-inch thick cement walls.
But, if you're actually that curious, just look it up. You'll get better information than from asking some random guy in the comments.

Omg first we run out of sand than salt water whar will we do
Has there been a salinity decrease anywhere except the AMOC?
Has there been a salinity decrease anywhere except the AMOC?
Two comments, hopefully redundant! 1. ¿Do you remember the story about bulk carrier ships taking sand from Scotland to Saudi Arabia? The sand in Saudi Arabia is from a dried up ocean, and therefore contains salt. The cost/quantity of water needed to wash the salt down to a level useful in construction was greater than the cost of shipping salt-clean sand from Scotland. 2. ¿Do you remember the California gold rush? The layer of sediment laid down in San Francisco Bay 150 years ago contains so much mercury from the gold works that this sediment must not be disrupted. ¿Did I get this right?
For a great doc on this, check out "Sand Wars" It was really good, disheartening, but good.
I understand the need for sand to make concrete and glass, but using sand to restore beaches seems like a waste of the sand. Sea levels are rising and hurricanes are getting stronger, so humans should be moving away from the coasts instead of trying to save them.
Agreed. It's like they're using these massive pieces of equipment to move sand from the bottom to the top of a pile. It's the definition of insanity.
@@jordrider1917 using a ton of energy in the process, burning fossil fuels, adding to the problem
Buncha sand-huggin' hippies.
Not an option
I think the misunderstanding here is that they're restoring beaches for human use. The way I understood it is that they're trying to restore environments used by wildlife. We're destroying their habitats, so we're trying to fix it. It's not the best solution, as they said in the video, it's just people doing what they can until a better idea comes along
Does the USA not have recycling bins at people houses?
Where I am the recycling price is built into the up-front purchase of the beverage-container.
I live in the US and yes, "recycling" bins exist, but what's in question is what happens to the material. I am given to understand that not much of it is recycled. I'm so convinced that there is in fact no plastic recycling, even though the propaganda says you should put it in the recycling bin, that I now routinely send all plastic toward my county's incinerator.
Glass bottles are the one thing that can be recycled without deterioration. Not doing it because we "can't afford it" is dumb. We can't afford to live on with our heads buried in the sand. We need to do the simple things, there are much more complicated challenges ahead than recycling glass bottles.
I remember hearing years ago that Singapore had stolen a Malaysian beach. I was surprised. I couldn't figure out why.
Please apologize a dumb question - but isn't 're-sanding' beaching nothing more than a matter of comfort rather then necessity?
Sand protects the coastline.
@@GenRN I suppose so, but naively I would think that wave breaking barriers could be more effective and longer lasting. Again - ‘naively’ being the keyword here
The beach protects the land from erosion
@@ecurewitz is there maybe a more efficient way to protect the beaches that would not require so much send being dug out of the ocean floor?
California is washing away. A woman went to the beach on fine day and sat under the cliffs in Del Mar. She was crushed death when the cliffs collapsed above her. The lack of sand caused the ocean, during storms, to carve out a nice place to sit on the beach. Then it fell down.
Can concrete also be recycled? Fewer people would help as well.
this story makes me remember the "recycling wars" (coined by a friend). 2 companies stole each others trash containers and/or contents because it was basically free money (the trash truck would drive through there anyway and trash was auto sorted up to 90% at the facility) and the "war" kept going for 2 years or so until thepolice and DAs got involved.
in the end both sides paid fines etc. and not even a decade later they merged... funniest story I ever heard lmao

I had hoped for an answer to how much damage to the ocean ecosystem is caused by dredging, but alas
If you are going to inflate archaically, you should do so properly. "But" is a conjunction and "alas" is an interjection. They should be separated by a comma. There is really no scenario where they should go together, like this.
Literally went to the comments to bring up Glass Half Full and then saw her face in the intro lol
Also the building of homes so near the beach that happen so often in the US can and do affect, here at my country ever since we’ve been getting lots of Americans gentrifying our beach coast they’ve been illegally filling wetlands with beach sand which cause a huge problem in many ways these people don’t even care to understand…so building infrastructure should also consider if the location will unnecessarily make more use of sand by having to fill in the space completely while also destroying whole ecosystem that also protect communities from flooding

M-Sand is available, Recycled glass is available as substitute, coal mining waste and recycled concrete is another option. Four better options available and sustainable!
People say that concrete cannot be recycled. Concrete is fairly inert and has a lifespan, but it still ends up in landfills.
When I think of sand I think of the Sahara desert, the Gobi desert, the Arabian desert, the Kalahari desert, the Australian desert, the Arizona desert, etc. Perhaps it is a problem of vandalism or unregulated capitalism instead of "sand" scarcity.
Most of the Arizona desert doesnt have much sand. Sand dunes exist, but they're really mostly just down by Yuma on the way to the Gulf of California. Most of the rest is dirt and dust instead of sand
I didn’t realise the coastal erosion of Louisiana was so intense. And that’s with the reconstruction efforts…
More people who think sea level rise isn’t real need to understand sea level rise doesn’t mean constant flooding (in most places), but it means receding coastlines!!
That said, I do wish PBS with its reputation for accuracy would say “Queen of the UK” not “Queen of England”. I don’t even like having a monarchy, I wish we didn’t have one (I guess that makes me a republican, though not a Republican!), but the phraseology does minimise how important Scotland was in its history.

Okay, so where is all the sediment going that would naturally go to the mississippi river delta? It cant just be disappearing. Take it from whereever it is ending up and use it to rebuild the coast.
