This article makes no mention of biomass per acre when farmed. As a C4 photosynthesis plant, bamboo presumably grows more biomass per year than other trees. If true, that would seem significant enough to outweigh many of the disadvantages.

I wonder how it compares to rubberwood. Rubberwood has to be cut down (and used as lumber, etc.) and replanted as yield diminishes beyond biability. The downside of rubberwood is it does poorly in damp climates.

Iirc, there’s a bamboo tree that grows very fast and has been considered for carbon sequestration. But the problem is, as with all trees, the carbon isn’t locked away from the atmosphere. It also takes up valuable farm land as they need something more like marshland than drier, more common land.

What if they (like trees) just bury it very deeply? Oil and gas are basically old trees and sea life that was buried - stored, and would have been for a very long time if it wasn't due to people.

Relatives that lived in Japan brought back bamboo stuff to the US, and it all cracked within a year or so. The reason was that bamboo does well in wet climates where the moisture in the air keeps in flexible. (or something like that) But in the US, it's much drier (most places) than in Japan. This fits with my experience of bamboo furniture over the years as well. It becomes brittle and fragile the older it gets. But…

I don't doubt what you're saying, but I wonder why my bamboo ski poles don't crack. I have lots of them, and they've been used every winter for nearly forty years, from back when I bought them. They're as good as new, still. I bought all the stock of the last shop selling them at the time, in my student town, as I didn't want to use fiber or metal poles in the mountains (can't easily be fixed if they break, while bam…

I am sure they are treated differently? Just a guess, but maybe with an epoxy?

The list of uses is missing the best one: clothing! Bamboo fabric is very soft and comfortable, if you haven't tried it yet you should! Downside: it doesn't last as long as cotton, and takes a bit longer to dry after washing.

Be aware that the clothing isn't made of bamboo fibres in the way someone would expect, especially based on how it's advertised.

They are generally Viscose rayon but use bamboo as the cellulose source rather than wood. I think several companies have been fined/prosecuted/told off for misleading advertising.

I have engineered bamboo "wood" flooring that I like a lot and after a few years haven't noticed any cracking or warping; perhaps it went through more extensive treatment processes?

idk if it is the best use, you need pretty nasty chemicals to make the fibers.

Interesting. I did a bit of reading about the process, and it seems like it doesn't have to be a problem - "bamboo cellulose is suitable for a closed-loop viscose process that captures all solvents used."

I wouldn't assume that all factories in China et al implement such a design and take worker safety into account, though.

Bamboo isn't going to replace lumber for most permanent uses, but it sure is handy when you need to put something together in a pinch. I was once trekking in northern Thailand with some Akha hill tribe guides. When it was time for dinner, they cut down a large bamboo and within minutes fashioned essentially a complete dinner service out of it: * A framework for their overnight hut/lean-to * A pot for boiling rice * A…

Hey very cool. Not exactly related, but if you are interested, I have an adventure journalling side-project I am working on. I would love to have more techie travel/adventure loving folks on board... https://outsideways.com/

Wow, those bowls are great, yet so simple. It's amusing to think they'd probably be about £25 each from John Lewis.

Maybe they'd need some kind of treatment to last?

Bamboo is anisotropic like timber, which means that expansion and contraction caused by drying or temperature variation will happen at different rates along the tangential, longitutional and radial axis. Crack happens when stress exceed the tensile strength of the material in one direction. Thus a long and thin object is less vulnerable to this type of failure as only one axis undergoes a significant change in size.

In addition, the bamboo ski poles may have been thoroughly dried by kiln heating and sealed with some type of resin or lacquer to prevent moisture ingress, especially if they were made to get wet.
