Bamboo: 21st century steel | David Trujillo | TEDxCoventryUniversity

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

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.

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.

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!

[@user-jh6vt8vx4v]

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....

[@samguapo4573]

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.

[@jean-pierredevent970]

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???

[@lewisdoherty7621]

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.

[@lewisdoherty7621]

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.

[@b_uppy]

Lewis Doherty 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.

[@StofStuiver]

[@Jfreek5050]

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.

[@mbharatm]

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.

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.

[@seung-hyuncha1439]

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.

[@milagroswerle9645]

Me parece que sólo estás hablando desde la perspectiva del "primer mundo".

[@whiteperson806]

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.

[@samguapo4573]

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.

[@mbharatm]

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.

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

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.
