I came across this and thought it was fun, just another wonder of hemp. Apparently this process has been traced back too Egyptian times. I personally am ecstatic about the new farm bill and its allowance of hemp to be reintroduced to the market even in what little form has been allowed, this and the forward gains being made in the straw industry alone will stop the deforestation of America. Building isn't the problem, its packaging and papers. Woody Haroldson has invested heavily into this process and is a major contributor to a straw paper mill in Canada, I believe in Alberta.

So, its essentially like light clay straw with a lime stabilizer and maybe some MgO? Any cellulose material will work? The part of the hemp plant they are using is a byproduct of fiber processing. I do not see that it would have any particular advantage over other things like wood chips, straw, rice husks, cattail leaves, etc. Hemp is trendy, so there is a strong marketing angle. Importing processed hemp byproduct to be"greener" is a contradiction (same with shipping straw bales or rice husks). Use what you have locally.

I'm a very very far cry from being anything close to a structural engineer. I do seem to remember seeing someone who was go on at length about why cannabis as a building component was superior to pretty much anything. Something to do with fiber length and strength I believe. I'll see if I can hunt down the link. I agree though there are a nearly unlimited amount of great building materials out there. Could something similar work with straw? I don't know. It'd be great to see some demonstrations though. Going with whats local definitely makes the most sense. Igloos for the Inuit and all that. Of course one undeniable benefit of industrial hemp is the sheer amount of biomas (and thus building material) generated in a single season is nearly impossible to beat (maybe with papyrus given the right climate?) as well as the vast expanse of land which industrial strains of cannabis are capable of thriving on. The only reason most of the US would have to resort to importing this resource from afar is due to sort sighted legalities, not its ability to be produced locally.
