- Every year, the production of cement accounts for 8 percent of global CO2 emissions. If the cement industry were a country, it would be the world's third-largest emitter of CO2. One company working to reduce the carbon footprint of cement is New-Jersey based start-up, Solidia Technologies. Its cement mixture and curing process can cut CO2 emissions by up to 70 percent.

This Green Cement Company Says It Can Cut Carbon Dioxide Emissions
I like this guy. "We have to use 3rd party testers as no one's going to believe our data"
Those are the confident words of someone throwing down the gauntlet and saying come at me, I can back it all up.
He's also realistic about implementation which is a nice change from all the CEO's who are just talking 100year future BS.
Unfortunately they are still a private company. But I'd be keeping an eye on them. If what they say is correct that it's actually cheaper, stronger, less water, better colours than the second it gets approved and can be made in ready mix companies will switch in a second and won't even give a dam about the green side. If you can save the environment and increase profits by doing so, then that's how change will come about.
Soviets done it in the 70s. By putting aluminum slag into the concrete, it releases FAR less CO2 while drying/curing. It's so funny how all these "NEW" ideas are rehashed from old and everyone gets thrilled.
Third party testers is the standard in the construction industry.
Owners hire a third party testing agency to test soil compaction of structural backfill, concrete, and steel that the general contractor installs.

@@Watsongab123 Is it normal to use universities for testing as well? It looks like this guy is going 1 step further and using unis etc to do independent peer reviewed studies, No doubt such studies would appease any hesitant regulators or give them something to point at to justify any approval/use but its nice to see someone that is realistic about what they can do and is happy to have people verify it.
Link Knight do you have a link? Super interesting.
@@phil2782 Testing agencies have their own soils labs but so do plenty universities that have civil engineering programs.
These are good steps and the final step would be adoption by the ASTM and ACI for ready mix concrete.
CNBC always shows footage of steam when talking about CO2.
hilarious
The reason is simple. For one smart erudite like you, we have 1000 people who wouldn't be impressed by the footage of a chimney with transparent shimmering over it. Because that's how CO2 looks like. I don't think CNBC guys are ignorant. They just make a product for the broad public, general population so to speak.
@@michaelcrockis7679 of course. but its the result we want, anything to achieve it. cd Carson did a great interview on nuclear. btw....
Pretty much the same as "The sky is falling"
@@michaelcrockis7679 For sure, it's just fun to be a critical smart-ass :) It is super ironic though since nuclear power is a carbon neutral energy alternative.
and here i am, thinking the title was implying literal green cement..
Also, red and gray.
Me 2
Starting at 1 minute, the video has a graph showing that atmospheric CO2 levels are 400 parts per trillion!! According to NOAA and every other source on the web, atmospheric CO2 is 400 parts per million! So the video is off by a factor of a million.
I found this odd too. Wonder why CNBC hasn't corrected it yet
All those juicy crops to grow with water shortage from all the heat 🥜🧠 nice one
Civil Engineers should know this. There is an "Photocatalytic Cement " which is also known as "Pollution Eating Cement"
yeah, but it is not working like very good. It is a certain type of titanium dioxide which has those propertys. The problem in the construction sector is that it is already very expensive to build if you then add costs to it, people wont accept it. Plus making TiO2 consumes a lot of energy and it is not really "eating" pollutents away. They are still there but in another form. Also it is only acting on the surface but 80 % of the photo active substances do not even have tha chance to act and react. One of the few materials who could change the industry is geopolymers, which why i dedicated my work to them.
Just curious, when the mix is in 1200C oven, it releases CO2 + other gases... can that exhaust gas be rerouted to cure the blocks later down the line?
Good thought! You should go interview with them and them give them the idea! I'm not being sarcastic.
That's what their imply, It's incredibly difficult to "capture" natural CO2 to the point that is easier just to mine the stuff out of the ground or burn something. Capturing burn gas off their kiln would be the cheapest source of CO2 for them.
Great thought, however I would say probably not. It sounds like the CO2 jumpstarts the curing process. One would not want the cement in the concrete to cure until it’s been placed in the desired location.
Typical concrete, made with Portland cement, needs to be placed within 90 minutes of batching to be considered to be within the compliance range (that 90 minutes can be extended with chemical additives). So if their substituting CO2 for water then one must assume that the CO2 should be added to the cement after it’s been mixed with the sand and aggregate.
I like the idea, because it can be refined and harnessed to inject into other building materials.
@@Techtachular - this version seems to be more of a first generation iteration that focuses on pre made concrete blocks instead of pourable concrete. Not a full solution yet (if ever) but a great means to start to curb the CO2 emissions. If it is viable at all to mix the cement, co2, gravel, and sand on site int a pourable concoction we are not there yet if ever.
None the less, since the process is still reliant on Kilns, and pre made blocks are not going away, there is still an avenue to use CO2 smoke capture during the heating phase. All efforts in the right direction.
I could see this being a good replacement for existing CMU products on the market, depending on the structural properties, sizes & shapes, and finishes available. If the available Solidia masonry sizes are identical to standard sizes, and prices come in the same ballpark, using them is as simple as writing a small specification or note on a CD set. I’ll have to look these guys up for my next project.
The catch is that Solidia is currently making pavers which are usually made from waste concrete that comes back in the concrete truck after a concrete pour....
Selling at a premium? Why? Sell for cheaper. You said less energy needed, double the output with same materials.
All the R&D, marketing and third party testing take money. Until more people get on board, it's going to stay expensive.
Jalen Davis economies of scale. If governments introduce a carbon tax it will change everything.
NEUTERLibs the amounts of increased CO2 in the atmosphere have no impact on plant growth. So reducing it back down to pre industrial levels would not decrease any growth. When plants are grown indoor environments the level of CO2 is increased to 1200-1500 ppm. We are talking about one quarter of that currently in the air. Maybe you should revisit some Highschool biology.
@@MoDa87 Oh yeah, more taxes! That has always helped in the past!
Why they showing nuclear when talking about releasing CO2
Because they want us to NOT think about going nuclear
@@LucianLusilver probably because visible "smoke" or steam looks worse than showing nothing
Because nuclear power does not emit CO2 and that is a better alternative than coal, oil, and gas plants.
We want to go greener that's why.
How do you know it’s nuclear? Coal power plants use cooling towers too.
Talking about CO2
And they start the video with Nuclear Power Plants Steam Tower.
Nice..... 🙄
Nuclear power plants do not emit CO2. Coal, oil, and gas plants do on the other hand.
@@CBC460 exactly
Nuclear power plants are concrete-made structures
For some reason when I read the title I thought the cement would soak up the carbon dioxide :)
They really need to explain how the heck the product is flowed into molds and forms without water. And then how CO2 is "mixed" in with the product. Is the product sifted in dry, and then the mold is suffused with CO2 gas, replacing all the air? Is liquid CO2 used? What!?
They recycle the water, and they fire their pavers in a high CO2 atmosphere.....
You can probably contact them like a normal businessman would do. I don't think a few minutes on youtube would be enough. This would be more a 60 minutes interview
What are the mechanical properties?
That's what I was wondering.
Probably bad. Which is why their choose to use it for non-structural bricks.
What a waste of time.
@@dess3597 Nope, they just don't want the liability of selling blocks for construction yet....
The properties will be same as ordinary concrete or their pavers would fail.
However, they won't be making Portland Cement for High Strength Concrete anytime soon as that requires significant long term testing...
That is what I always say about infomercials, “If it’s so great why isn’t it sold in a store?” We already have NHL which cures in the presence of CO2 and water. It is halfway between cement and non-hydraulic lime. It takes less heat to produce and absorbs CO2 as it cures but takes longer to initially become hard and ultimately does not have quite the same strength (although pretty close.) So for some things you just beef up the thickness. So now I am wondering, chemically, how does this differ?
Congrats for 1M subs CNBC. Keep making amazing videos 😇
Does it have the same compressive strength as traditional concrete?
Well you can say it can do something for the environment , but are you actually going to do it!
Exactly my point
The thing is it would be so popular if there is additionally a carbon tax
They are not making it just for fun....
Would it be possible to use a carbon capture method in regulat cement production as an alternative to green cement?
or use 25% ash with klinker ie pozzolana cement.
Where would concrete companies get the co2 to use instead of water to mix on construction site?
What about the durability of the green cement? Was waiting for comparisons, but found nothing on here. What is the price of this green cement compared the the normal ones we use?
When no one mentions anything about the price of the "new thing" it usually means its more expensive than the original. Whats the cost difference between producing this cement and the cement being used now cnbc?
They say at scale its upto 30% cheaper than whats currently being used. ATM Its more expensive and the market is eco-conscious consumers
Concrete pipe would be an interesting product to expand to. Then there are precast concrete bridge beams, precast drainage inlets etc.
How recyclable is it compared to normal cement?
All concrete is recycled as a building material, after is run through a drum crusher.
Then it is usually used as a base material, such as laying medium crushed concrete, then fine cc and then gravel for making a road....
But how does it hold up against road salt, snow plow blades and putting rebar in it?
I suppose it is some kind of Roman cement (which would be great :) Arguably, the binder could also be seen as a geopolymer as sometimes it is hard to decide which word fits the best and quite some times many different do. Roman cement, or metakaolin-Ca(OH)2-geopolymers, can be made by oneself. But of course it is a good idea to buy a tested product if you want to build with it. The diy way is rather for experimenting but in theory it can be good to make buildings from it.
Do no mention in price, resistance property and only precast elements??
Great content. Very interesting. 👍
We need more people to get on board with this. We need more politicians to take action and endorse these better alternatives for the concrete/cement industry. Governors should charge the concrete/cement industry for emitting co2 into the atmosphere. Maybe that way they will switch to more environmentally friendly alternatives.
The productions are so nice.
Great looking product. I hope it does not require more sand to make. Sand is becoming a very scarce commodity since what everyone needs is river sand, not desert sand.
Brilliant research. Thanks
9:15 "...will reduce CO2 emissions by 4% *shows image of zero emissions nuclear energy plant*
Because journalist are not scientist, they see smoke they think it's CO2, in fact nuclear energy plant smoke is just water vapor. I don't think reporter give a crap, or do any research. Like this "green cement" or "clean coal"
Maybe use the CO2 from the truck to make ready mix
Only critique I have on film is the temp is not rising drastically. A 1.6 incline over 150 years is not something to write home about.
If this is so true then why have I not heard anything about this in Scientific American or Architectural Record? You would think engineering and concrete firms would be lining up to do business with this company by now. I hope to hear more about this company and it's technology in the relevant engineering publications. I will really know the technology has arrived if it makes it to the Canadian Building Digest reference publications.
Because economies of scale. Portland concrete is way cheaper, these new things take time to become cheaper, if nobody adopts em they stay expensive so someone needs to adopt it first to show everyone it can be feasibly used. But really what most companies want is lighter and stronger concrete. which reduces the architectural/engineering cost, the green stuff is just a bonus.
love this. the ferric stuff too.
So if the concrete blocks drop then the trapper CO2 will be released back into the atmosphere, right?
Can they make armored concrete with this method?
Use salt water instead? (like roman concrete)
Roman concrete is very expensive
@@snow-rm3jx can salt water be used with this jew green cement perhaps?
I wonder if concrete roof tiles would be a solid market for this product?
That was steam in the fist clip. And I’m pretty certain that was that was nuclear power plant... geez
If they can make ready mix at a reasonable price they can make a dent the in concrete giants sales till then your homeowner and contractors will use regular concrete because of the simplicity of the product and price
my favorite type of disruption
great report. would love to see something about how the planet is running out of usable sand... including for things like concrete and glass.
Gotta get the cost down for it to be a big win
Isn't it easier to trap and use co2 gas for other industrial reasons like fire extinguishers?
The big elephant in the room is they said during the curing process so basically they’re putting it in an oven to curate. What about when you’re pouring a sidewalk or driveway are you going to hang an oven over it to bake it to make it cure? As of right now if you go to Home Depot and buy a bag of Portland cement 94 pounds and mix it up into Cement properly with aggregate if it’s below 50° outside the It will not cure properly and that’s because they’re adding up to 15% Lime stone
I request you guys to make a same video on JSW green cement and Indian company they are already selling the green concerte and green cement.
WAIT what?
how do you pour it without water?
how do you set it in a place without water?
how does it cure?
Wow! Amazing! It takes less water to make and less heat and outputs less CO2! This should be used by all for concrete! How do we buy this?
This will add tens of thousands of dollars to the cost of a house.
Millions of dollars to a construction project.
@@mtorres3097 Only at first. Then the Chinese will figure out a way to do it for a fraction of the cost! LOL It should be subsidised though.
This was very interesting. As a civil engineer there is alway a push for alternative building products that are environmentally sustainable
The biggest way to reduce green house gasses from Portland Cement manufacturing is by using Solar Thermal energy to heat Sodium, which then heats the air in the Drum Kiln. Also the CO2 released from the batch can be sold to various industries....
Why don’t we do carbon capture at the source like a power plant or Cement Kiln
There must be some downside I bet its something like the final construction last much less longer. Businesses will always adapt anything that will save them money but it must do the work.
Is it from cement itself or is it from the process of which cement is produced?
From the process
Even the GIEC is not so certain about CO2 and temperature. The beginning is to assertive.
How can I get a hold of a company making this cement?
3:28 1 ton of co2 for a ton of cement?
if usa stopped building huge concrete highways would reduce the co2 alot
@Secret Sauce is Overrated most us highways are made by levaling it putting asphalt then covering it with upto 2.5feet of concreat where rest of the world builds the road up with diffrent size stones then concreat then asphalt its been done like that since roman times but usa still prefers to do things backwards not only do we have roads that are easyer to maintain but we also have better drainage
@@ppercut It has been probably 50 years or more since I've seen any kind of major road in the USA made with a concrete surface
@@cindytepper8878 have watched a fuw programs how they make them think now there spraying tar then spreading stones ontop tp make them look better they have even done it on sum almost dirt roads with makes no sence to mewouldent suprise me if diffrent states did it different
@Secret Sauce is Overrated think its just quiker but over years been alot of mobs gettin pay offs to supply the cement
@Secret Sauce is Overrated czcams.com/video/MgvUDs5tcu0/video.html
SOVIETS DONE IT IN THE 70s... they used aluminium slag in the concrete and it dramatically dropped the amount of CO2 when the concrete was curing. And they only done it to make use of all the aluminum slag they had from their smelters....
What about carbon sequestering concrete.
only prefab, no pouring
We as human only serious take on these unique efforts last minute before it is too late for change
This should be a go its marvelous.
If you have to harden it before you give it to the costumer it doesn’t make sense because you can’t mold it into what you want
It does have a place in modern society which is incredible!
Says 40% less energy then sneaks in 30% 😂🥴
What if you don’t use limestone? Would you have a sustainable product?
What happens with the c02 when the concrete is demolished? Is the co2 reliest in the air?
It's not a Ballon.
It would go to landfill with the rest of the rubble.
@@phil2782 what in the hell is a ballon
I literally cracked out in laughter from that 🤣
If you have a good plan, the company will be at a deficit for indefinite amount of time, just like any other companies out there. So, might as well cut the price on the cement right now. Also, government should provide green technology credits and subsidies to business who are buying this cement in order to make it an attractive product.
Companies that I love to invest in.
An excellent idea, if we use it along side Solar and Wind while also ending the oil and gas industries all together.
If only a bureaucrat somewhere could be brave enough to think like this. An all out war on climate change ,on all fronts.
0:01 There is already a mistake. Those distinctly shaped towers commonly found in nuclear plants are cooling towers and not smoke stacks. When the narrator says "when we think of things that relate carbon dioxide into the atmosphere" and shows cooling towers this is just wrong. The vapour you see coming out of the tower is water vapour, aka clouds. Not CO2 as she says. C'mon guys. (In a chemical engineering student and we just covered this is class so that's how I know)
In Warsaw (capital of Poland) we already have "green" pavements which basically absorb the pollution from the cars riding next to them.
my dumb ass actually thought it was green cement
excellent
And the shipping industry??
Unregulated fuel in international waters, the worst fuel used dumps how much carbon?
Carbonation in concrete is a bad thing. Decrease in strength
Concrete blocks only. So not even remotely ready for prime time. Wake me up when they make bridges and foundations out of it.
Yea the best use for this at the moment is concrete pavers. Of course they cost twice what the regular pavers do. But if it was industrialized the price would come down a lot. Still there is no one solution but at least this is a different idea. Would like to know more about how the curing works.
Let's make this trend!!!
how to apply job in your company??
Hello, They have HempCreate. Why not use Hemp ppl ?????
Because it’s still using cement?
One of the most infuriating things i see in co2 emission videos is when people use clips of power plants that emit water vapor with the intent of making the viewer think that it's actually Co2
Disgusting.
I love how CNBC always shows the typical nuclear plants with a lot of smoke in the air to depict 'polution'. Eventhough it's just water vapor in the air...
All the MSM do the same thing.
I don't get it.
Well it works for them, I knew someone who legitimately believed that clouds were just straight pollution
😁 Sure.
I didnt know steam creates co2.
How do I start making and selling bricks. Someone please help.
I clicked on the article already knowing CO2 is a MAJOR byproduct of concrete, cool ideas!!! YOUR NEXT TOPIC SHOULD BE **" Why is greek concrete ocean barriers gettings stronger, while modern concrete ocean barriers are disintegrating."**
Because I know the reality of the truth that is really happening, I was understandably sceptical, but trapping carbon inside the cement is really brilliant, not just eliminating the production of the emissions, but Also trapping thermal gases inside the substance, creating insulation. Brilliant, it could not only reduce emissions but create a new hybrid manufacturing system that injects harmful emissions inside of building materials as insulation.
This product is amazing. I am a want to be Real Estate developer. Also I am a Realtor. My true Passion is to be a Humanitarian. My vision is to design master planned communities for all income levels.
Along with knowing that solar panels will come with all of our properties, now we know who will provide our cement for all of our cement needs.
Amazing Company. ❤🎖🥈🏆🥉🏅🥇🇺🇲🎈🎈🎈
Nazik Adam no it means a person who helps other people. Like the Red Cross is a humanitarian organization
@Nazik Adam
😂
We need co2 instead of dealing with it they should start dealing with Nitrogen oxides and CO
sad how money is the most important thing to a company, not the well being of the only planet we know that can sustain life...
Money is the most important thing to any company otherwise they wouldn’t even exist, you can’t live off of kindness sorry to burst your bubble, kindness doesn’t pay the bills. The environment comes third after money and costumers
Sounds like NHL 5.0.
I made this already its called hempcrete
One question, with the older method, why isn't the CO2 trapped and not released into the atmosphere?
That frankly sounds like much simpler an issue to tackle.
Were are going to store it each year. That's a lot of space and money, it's a loss of money to store it and not have a use for it.
many of us want to know that answer.
@@Wonka1776 cos for carbonated drinks? Fire extinguishers?
nuclear power does not emit co2.
The industrial application of thorium molten salt reactor thermal output, could cut CO2 for cement production decades ago, except for a bad political decision made by Richard Nixon 50 year ago. Thorium reactors are being built now, better late than never.
if it is that much better and economical then the sales pitch should be enough to win the market instead of talking about climate.
That doesent get you on the news
Might not be as profitable or require capital investment which age old companies wouldn’t want to do since they’re happy raking in $$$ from the current system
Ok. But what is the net total of co2 released during production, shipments, and placing of this cement
all that maths on chalk board at mit and what do they tell? just heat up the mix to make cement?
There are rivers that run all day everyday 24 hours a day generation after generation more water than you could use in a lifetime every minute and they speak of water conservation.... Really?!
This was a good vid
