- As the world turns its attention towards the sustainable development goals, sustainable architecture offers a very interesting prospect of minimizing negative environmental impacts by buildings, save energy and safeguard human health and well being.
In this talk, David explores the potential bamboo creates and how well it can be a wonderful and strong tool.
David was born, raised and educated in Colombia where he studied Civil Engineering. From 2000 to 2003 he contributed to the reconstruction of the Coffee-growing region following an earthquake. Here he became fascinated about bamboo structures. In 2003, he moved to the UK to study an MSc in Earthquake Engineering. From 2004 to 2009 he worked in consultancy, working as a structural engineer. His work ranged from multi-storey timber-frame structures to very large steel and concrete buildings. In 2010 he became a chartered structural engineer. In 2009, determined to research bamboo, David joined Coventry University. He currently chairs an international task force for Bamboo Construction.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx

The problem was the decay of bamboo after five years by fungus or other detrimental forces. Now the IBUKU Organisation in Indonesia and Bali found a way to put the bamboo into a liquid which is borax salt and now adding stability for more than hundred years.
Dr. Trujillo was my lecturer at Coventry University. He really made me appreciate the value of non-steel/concrete structures in the Timber and Masonry module.
Brilliant !
More and more bamboo.
One thing not discussed in the talk is the comparison of lingtivity between bamboo and steel and timber. Also the challenges and impacts of treating bamboo.
Having tested Bamboo materials for a number of years, the fact that common Borax (cheap and at the grocery) really makes it last years longer than normal is fantastic. Let's really study this grass. It also does not requie toxic fertilizers or much water: HUMMM?
We have a bamboo farm. This has been a very primitive and a very ancient way of construction for majority of the dwellings around south east Asia. We have been also working on pile systems using a specific breed of bamboo and it has proven well for 50 years without any decay into the integrity of the structure.
You seem to have a lot of experience. How does bamboo stand against: rain / moisture, earthquakes, fire?
Kindly teach me how to farm bamboo
Can I get your email address
Which breed of bamboo?
The Bamboo is best since 3000 Years !!! Just this natural nice présent dont have the strong lobbying same the steel and plastic industry !... Today Mister Trujilo and me we strong work for return the old forget time !... Thanks dear David !
Poles actually reach full height in about two months, but it takes six months before it's hard enough to bother cutting. It's the strongest when those poles are 3-5 years old.
I'm actually looking into starting a business with bamboo farming in North Wales
I want try a planting for bamboo.. I don't know how to planting & all.. If u know let me know about this.. Which soil is suited for in India... Do you have any idea. Plz tell me
Hw many spices are there.. Which type of bamboo have more demand...
@@ksaradhi2571 Tropical areas like a jungle.
Hi Mr Undead,
Im also intrested in starting a bamboo business. Doing something against climatchange and creating jobs.
Do you have any Experience with this? Have you proceeded with your plans?
I'd like to learn from you just as @Sabbineni Sri Harsha
Mr Undead want an investor ?
@@ksaradhi2571 You must read and research this stuff for YOURself. No one is going to spoon feed you at the bottom of a RUclips video.
Life is not that easy. You need to learn how to read and write English and join groups that research and grow it so YOU have your own knowledge and power. Ok?
Then, make a budget, prepare to spend LOTS of money on farming it yourself. You cannot expect people to give you everything , but I believe you can attempt to get a savings account and begin saving to buy, ....Land, plants.
If you only burn the bamboo to charcoal as in a gasifier, the remaining carbon is still in solid form and can be buried as compost or to filter water.. So you could make electricity and charcoal (carbon).
I'd also be interested.
Im also interested pls
i m interested pls send the process
please am interested
'm interested too. Any idea? Please share for which I would be thankful. However, lot of thanks.
Just planted my two river cane plants 2 weeks ago to start my grow. Plan on building lots of things with it. Hope others catch on as well. Certain species can grow even with harsh winters.
What happened now
Dr Bharati Nambi, an Indian scientist and the director of Growmore Biotech, with 37 years of experience in plant tissue culture developed a special variety of bamboo called the beema bamboo, with a 100 year life span, showed a 7900 percentage (%) hike in yield compared to the traditional bamboo that’s being planted. Regular bamboo yields about 0.5 tonnes per year, beema bamboo yields 40 tonnes per year in 1 acre. A fully grown bamboo to produces over 300 kg of oxygen every year while beema bamboo can produce 62 tonnes of oxygen per year and can absorb 88 tonnes of carbon dioxide a year per acre. This was in 2010.
You can also put a form around bamboo, when it gets to your desired length. Once fitted, you just keep cropping the green cola at the top of the plant. It will grow outwards to fill the form shape. Result: Engineered Bamboo. Some bamboo clump and do not travel. Others will travel underground and take over the landscape. The shoots are delicious and nutritious.
Wonderful experience..I am a bamboo lover planted 10 bamboo plants (dendrocalamus brandisi).now feel cool atmosphere.thank you for information.
In india bamboo has importants from thousands of year..today in many temporary structure are made by bamboos we called it as 'mandap'. Also in many civil related activities bamboo is used like for painting of buidilng,plastering,plumbing,as ladder ect... Eventually bamboo can be next big economy
I love these environmentally friendly houses of bamboo and all its great potential for other eco friendly products! Its definetly the product of the future! Yes, MAKE BAMBOO MAINSTREAM!
Besides using bamboo in construction, like in concrete and replacing steel in some instances, You can use lignin and other biopolymers for carbon fiber outside of aerospace for better quality everyday products that are cheaper and carbon negative
Bamboo doesn't grow only in tropical climates. Some varieties resist temps of -20°C which is very cold. I agree bamboo must be integrated in the array of building materials in Western countries considering its very low cost, a lot more ppl could afford houses built with it or even build their own.
Whew! Awesome research and words and sentiment
Strength is only part of the story, any good engineer can tell you that ductility and modulus are just as important if not more so that strength. The likely solution will require genetic splicing and farming of bamboo and developing a composite, if any budding material engineers or plant biologists are reading this, then take this is your challenge to change the world!
Loppy2345 There is no true ductility in organic material. You are not likely to see this term in composite material either. These are all consider brittle material. And above all, it is not homogeneous material, so one youngs module is not able to represent the characteristic of the material. Same goes to composite material....
It's not ductile but it is also not brittle. All materials have their strengths and weaknesses. It's just a question on where to use bamboo appropriately esp. since it is very easy and quick to grow. Iron bamboo can be incredibly strong in full maturity. With heat treatment, gets even much stronger. For the sake of non structural use, there are bamboos that grow to full height in a span of several weeks.
Loppy2345
Have you ever seen comparisons of bamboo scaffolds versus steel scaffolds???
Loppy2345
No gene splicing is ever required. Work with the Material to it's strengths, and compensate it's weaknesses. Use the right material for the job.
where on earth are you Sam?
We all need this! Bamboo ftw.
Is there a link to find out more about the bamboo houses he showed as an example (that were concealed in the walls)? Or how to frame with bamboo in a modern way?
So basically nature is far cleverer than we are ,so why do we not harness this?
Some do. Look up biomimicry .
Because, May be we aren't cleaver enough..!!😅
Because of the power of the timber industry...so far.
I agree with this mission!
The solution is a mixed forest of trees and bamboos, cause bamboos do not bloom with attractive flowers since they can multiply/clone themself instead of waiting for pollination, and flowers/blossoms and their fruits are important for wildlife and insects.
Bamboo is the future. I saw one company making clothes using bamboos. The Company is called Cariloha. I am investing in bamboo very soon.
Awesome & brilliant 🎍🎍🎍👍👍
If you burnned it in a greenhouse, you could transfer the CO2 to into plant growth, then use the biochar for fertilizer.
People in 17th century: "Steel, the 17th century bamboo"
I received this. Thank. I am going to follow and put in practice your suggestions. I am going to have a bamboo forest. Amen.
Im from phillipines can bamboo withstand 235kph wind coz we are typhon prone area
I guess that's almost impossible. But...you could have a sealable big plastic container under the house where all precious materials can be stored . Then the house itself should be made in panels and elements (bamboo/concrete based ? ) which are demontable fast. You bury these elements too before the wind comes. (bury them all together in deep special waterproof pits ?? ) Shelter should be found temporarily in heavy, half buried concrete perfect round domes which the wind can't attack (build by the community) I only wonder about the water and electricity, how they combine with demountable houses. Perhaps these could run and enter underground too and the bathroom would be the cellar and it could be pumped dry fast after the typhoon passed. It is possible bamboo domes could withstand a lot of side wind but they are rather light and so what happens if they get sucked upwards by a kind of eye of the storm passing???
Thank you for interweaving in a kind way the central issue of unsustainable population growth, perhaps the most taboo of subjects.
Wow they just discovered bamboo hurray
Interested, venturing in this industry!
Also we can consume young bamboos, they are sold widely in Asia and we Asians love them! Ver good presentation BTW.
Respected sir, I Love your idea and it is very useful for our future but I have one question. If we move to bamboo house then it is not risky in case of fire?
Come to Mizoram, India... We have bamboos everywhere... We eat the bamboo shoots...we built...we construct.. we have lots of variety of bamboos
If we find a way to build a lighter battery, electric bamboo cars seem possible with a huge action radius. I wonder if the aluminium air cell would not be such a candidate.
Nice idea! 😀😀
One word: fire
This should be shown to the members of the participating countries of the last December -'Climate Change' conference in Paris.
I'm pretty certain that many countries are already aware of this info, it just so happens its not on the top of their minds, or have not factored that in as a major solution to some of their problems.
He forgot to mention the Bamboo Bikes!
There are even bamboo car frames. But the bamboo bikes only consume a small amount of bamboo for the moment esp. since the cost of labor to make one is way way more expensive than regular bikes.
They are made in Greensboro, Alabama and shipped around the world.
Great.let us do in a great mood
awesome plant
"Beautifully engineered," as in God, the designer of all things?
You are misled
Or more likely as the produced of billions of years of natural selection. Either way we should be building everything we can out of it.
True as can be! Just as every other marvel nature given.
Watching this video 4 years later. Anyone know of publicly traded tech/material science companies or manufacturers that can be invested in?
now i am using it i am developing blocks i used to call it ( kawayan blocks) kawayan mean bamboo
Excellent
Yes, sir, I'm actually looking at your video, I want to study the mechanical properties of highland bamboo in Ethiopia would you send me any doc related to this study?
I agree to 💯
Fantastic 👌👌👍👍
Bamboo is good to protect biodiversity, livelihood and lives of the people.
OT, but since steel shipping containers are strong anyway, why do such railcars need a strong heavy i-beam chassis?
Why not simply attach the same 4 wheel bogey to the back of one and to the front of the next in a single height trainset?
I just want to ask about the fire resistance rating of a bamboo, how can you make it not susceptible to fire when you use it as building material? hope to get an answer, thanks
what about the ductility? In seismic analysis, ductility is one of the most important factors of design. Better we go with composite materials
That's a nice attempt
Good
is bamboo a water resistant material for constructuion?
as long as it isn't boiling temperature, yes.
Has he ever heard about industrial hemp? Another "treasure" of nature, "the" multipurpose plant.
being used in Germany in a few places
yes but it is mush mush more work and more thing that can go wrong
Hempcrete and bamboo house. I just came up with gold ladies and gentlemen. I'm a genius.
What would happen if i convert whole of a hill/mountain into a bamboo forest. Is there any risk of lanslide?
Will that be an earthquake resistant?
the solution is a mixed forest of trees and bamboos, cause bamboos do not bloom with attractive flowers since they can multiply/clone themself instead of waiting for pollination, and flowers/blossoms and their fruits are important for wildlife and insects.
@@Leotique Thank you dear
Sir, I wish I could present to you my designs maybe it could help more on housing using bamboo, it is not a typical housing but a new innovative designs using bamboo space, structural and flexibilty to environment and could be used in Low Cost Housing ideas.
Bamboo pipes; ag, drain, sewer
Roofing, gutters
Fence posts
Venetian blinds
Doors
yes, kick off and play... buy now...
I'm want to start bussiness with bamboo craf in Ethiopia
While bamboo would perform much better in earthquake events than masonry, masonry tends to resist decay problems created by the numerous lifeforms in tropical areas which live by oxidizing carbon. I know bamboo can be treated. But my perspective is shaped by living in southern Louisiana where we fight constant battles with everything from several species of aggressive termites to fungi and bacteria.
In addition, more of a problem than just rot is created by its excellent for weight to strength from its hollow tubular shape. While a cylinder has the best surface area to mass ratio other than a sphere, bamboo appears to be very flammable due to its double sided relatively thin walls with a lot of surface area. The thin walls are able to heat up quickly in a fire. While I'm not sure, it appears it may have a lot more cavities than many woods. The cavities also would also facilitate combustion by increasing surface area. Uncontrollable fires of structures made of bamboo could occur very quickly. The fire code drafters and insurance companies are not likely to go with it until viable solutions which causes fewer problems than the alternatives are developed. Would the bamboo have to be soaked in something very toxic to reduce the flammability problem? Would the chemical be cost prohibitive?
Bamboo is a resource which would solve many problems, if some of these issues are solved.
Yes, but then in the first case weight is added reducing one of their desirable characteristics and in the second case, the cylindrical shape is lost and the weight/strength ratio is reduced. The conversion to planks and solid beams involve the use of resins which often involve formaldehyde which people don't like. There are other things which are being used/developed instead of formaldehyde. Probably just allowing the products to be stored with easy access to air in a vented warehouse for longer periods would help. Formaldehyde breaks down in the sun's ultra-violet wavelengths into water and carbon-dioxide. So just vent the warehouses upward. It is also likely less expensive in many places to use tree timber for beams. The equipment cuts logs and the wood can be used. The bamboo has to have numerous cuts and then has to be pressed/laminated together with a resin or glue, then recut and then in many cases shipped quite a distance. Often it is just resource location. For example in Europe because the stems from wheat and barley harvests were a waste product of the annual harvests and wood was needed for other purposes, thatch roofs were used. But thatch was flammable. When the same people ended up in America with its vast uncontested forests, the colonists abandoned thatch roofs and went to wood shingles.

One use of bamboo where it is superior to steel is in the making of strawbale homes. Steel and iron can cause condensation which is an anathema to straw. If you use bamboo instead of rebar you can do an end run around the problem.
Btw you also want to use cob, not cement, on your strawbale house's walls. Cement is hydrophilic (water-loving) and could also exascerbate rotting in the straw.
The key to having a strawbale house in a subtropical climate is the concept of "good hat, good shoes". That means a large overhang (4+ feet) and a proper foundation will further protect these building materials from moisture and insect problems.
Strawbale homes made with cob walls have superior fire safety ratings. The fire can't burn into the bales because it is too dense. It is a lot like trying to burn a thick book. The outside layer might get singed but it stays largely untouched.
That resolves the issue of bamboo's flammability without resorting to chemicals.
@@b_uppy Forget that. You are talking experimental methods, which i can assure you are not going to work in any wet climate, such as Western Europe. And thats just 1 of the many problems. Nice for leftists to talk about, but no one else will be fooled.
I grow Giant timber bamboo on my land in Georgia USA.
Gotta say he kinda cheated on those CO2 emmission comparisons, considering that if we commercialized bamboo, we'd be shipping it all around the world, assuming we could not grow it locally with the same properties.
The problem with naturally made things, is that their quality often has to do with the conditions it was grown in. Thats why certain plants don't grow well in certain climates and why certain livestock are worth different amounts simply based on place of origin.
Well, isn't wood, steel transported around the world as well? Of course, there'd be some reduction in the amount of sequestering, but it'd still beat steel hollow.
Also, he's probably making a case for developing countries to use it instead of using steel and mimicking the West. Most of the urban development is happening in tropics, and if they utilised Bamboo instead, they'd seriously cut down on carbon footprint.
Use it locally. There are billions of people living in bamboo growing countries.
Can bamboo grow in north america. if so now where are these bamboo forests?
But how durable is it?

bamboo needs a refined way of making boards !!! Once that is achieved it will dominate the world !!!
Bamboo boards are already available. It is made in a few countries. Of course, China has some of the cheapest exports.
Plyboo is already one of the products made of that ilk.
Why boards? just lay down the whole pole alongside a bunch of other poles. I hear they do that down in the jungle.
it can be joined end to end with a steel rod and small amount of concrete..theres a span bridge in south america...
why just houses? You can use wood for just about everything where we use plastic. BAMBOO CAN REPLACE PLASTIC.
watch at 1.5x
Bamboo is a fine building material (and tasty food too!) but the the presenter's carbon footprint analysis fails to indicate that steel can be produced with clean renewable energy produced from sources such as hydro, solar, and wind. The majority of steel is recycled. (See steel on Wikipedia for more information). Furthermore, iron ore (the main component of steel) is very plentiful.
Steel producers in particular and manufacturers in general must transition to using clean renewable energy. Generally, government's accomplish these sorts of changes by changing laws (typically tax laws). However, wind and particularly solar are becoming so inexpensive that government's might not need to do anything in this particular case.
steel can be produced with clean renewable energy produced from sources such as hydro, solar, and wind.
can be produced through data manipulation, but in actuality isn't.
Me parece que sólo estás hablando desde la perspectiva del "primer mundo".
ken125y iron ore is a finite resource wether there is a lot of it or not. Bamboo can grow and regrow and never loose the land it grows on or the iron ore in that ground. Recycled steel takes more power to process than new steel so even though its a good thing its uses and availability are easily surpassed by bamboo. The research and composites have all been done and its currently in use now just not widespread yet.
The presentor should have included the comparative amount of carbon in steel in his example. I agree that mining and manufacturing of steel can be done with renewables but Bamboo's already give everyone a "cheat" to just let it grow and do its job for with no man made intervention necessary. In some USA states, the bamboo was made illegal to be planted because it grows like a weed and is hard to eradicate. I think these people should have a change in perception.
I seriously doubt Mining, transport and production of commercial volumes of steel is possible with solar/wind power etc. Plus the environmental damage caused due to mining is probably the WORST part of the entire equation. Plus the fact that solar tech itself pays off it's carbon footprint etc only after a decade or so. Forget about paying off the carbon footprint of steel.
What about 🔥 fire??
bamboo has the capability to resist fire... In fact bamboo is treated in fire to remove starch and any edible content that leads to pest attack.
Could Bamboo be also perfect for Mars?
No
Do like to share this interesting video please.
To be convincing, the overall economic costs must be considered and compared, growing bamboo, processing it, designing with it, building with it, service life and maintenance costs, disposition costs.
Governments should not intervene to make an artificial economy by unneeded regulations, taxes, and fees. This is the kind of skewing effort being applied to solar and wind energy unfairly, including letting regulated birds be struck by wind turbines without enforcement.
The argument of carbon capture falls short because global warming has been shown to be based on a hoax, measurements, models, and changing historically recorded data. climate depot dot com
how is it possible to store 10 kg of CO2 in 6 kg of bamboo
i hope this guy knows plantlife needs a certain level of co2 for photosynthesis to work^^
humm, I believe that at minute 11 the speaker makes an omission/mistake... countries like Japan, China, Mexico and others, keep all the knowledge regarding bamboo as the secret trade/techniques, if the desire is to actually use this resource as mentioned in the video, I believe that someone with a bunch of money should buy this secret knowledge and put it opensource, display it for free to all... the companies that have this trade secrets do not want to share the info... so buy this info... if you think that no research has been done you are wrong...
Robert Ostman ill disagree with this. Yes there is a lot of research but NO they are not trade secrets that are being withheld. Anyone can attend schools that teach this stuff. You can even find resources online.
What about fire 🔥?
These can we solved by coating film on bamboo which would resist fire✌️
@@MdAlam-qh3rf really ? which type of coating
Eucalyptus also grows fast, it's why there are eucalyptus plantations all over the world. Not as fast as bamboo, but it's a hardwood and it can drop into existing wood processing pipelines.
Hi John, just a point on Eucalyptus... they burn like crazy. The whole of Victoria, the state in which I live is declared a bush fire zone. Australia has the worst bush fires in the world, and eucalyptus dominate the landscape here.
Eucalyptus is not hardwood. Its water wasting rubbish. Sucks water like sunny leone. only viable for water logged areas
What about Paulownia?
@@dr.jahanzeb456 It IS hardwood. And it has quite some advantages to a lot of other types of wood. I grew 3 of them in NL and noticed:
They make very few side branches.
They grow lengthwise rather quick.
They can bend an awfull lot, without breaking.
After cutting down, some 13 years ago, i stored them just like the rest of the hardwood and noticed:
It doesnt rot as fast as the others, due to its thin bark that holds far less moist and gives far less shelter to insects.
It seems a tad lighter than the others, but very strong still.
I didnt have them grow very big. They were about 10m high and had a base thickness of about 10 inches. That is not really viable for a sawmill factory, although with them growing straight up, they had no bends or twists, so it could be done. Dont know what happens if you grow them longer/bigger. Considering their small footprint and all other qualities, i think it could be good replacement in specific segments.
Eucalyptus has a distinct disadvantage of consuming water excessively, though I'm in no way very knowledgeable on the subject , eucalyptus plantation in the place where I live is known to dry up nearby wells. So careful when you recommend it. Its just easy money, not the kind of sustainability we're looking at
It does rot
and we have to deforest millions of land :(
@@chinyerefemi3598 why would it take 3yr to grow back when he explaind that from the moment it pops out the ground to full maturity is only 6mo?

What will bambo do when fire starts to smile...
It will surrender then enjoy a fiery demise.

Bamboos is a grass, not wood.
@@b_uppy Bamboo is a grass and also wood.
content is good, but he speaks weigh too slow. this video could be done in 7 minutes.
I can't stand the way he speaks during the presentation. He's very much trying to hype up his research by speaking in this start-stop manner that very irritating!
Wow, my eyes are open. I live in a region where bamboo is plentifully available. I was wondering whether to go for cement concrete for wall but I've found the answer.
What is global warming advocates doing, let's not associated Bamboo with poverty, backwardness.
let go of your pipe dreams lmao
“ Is equal to if not better than steel “ is not a kind of statement you should be making on that stage.
Sorry, I can't watch this guy; he's irritating.
Yes, bamboo is the future. But please stop with this ridiculous concept of CO2 emissions. CO2 is very, very good for plants, and plants regulate the climate.
Oil is not fossil fuel and it is renewable and it is not in short supply. Also water is manufactured by the earth itself from hydrogen and oxygen either in the crust or the mantle, I don't remember which.
Oil is kind of renewable, but we have no idea how long it takes to be generated. We may be consuming it too quickly.
6kg of bamboo stores 10kg of carbon... wot
Adam Chase that's including the leaves and root system as well, I assume.
I assumed he meant it stores that much in the soil but that would count as the soil storing carbon
Adam Chase
When you burn 6kg bamboo its produce 10kg carbon in atmosphere
But bamboo is too easy to decay, and break easily. There needs research to solve these problems
No man. Mild steel tensile strength 160 n/mm^2 but bamboo 370 N/mm^2
Talk less about CO2, and more about Bamboo. CO2 is people breathing.
