Hempcrete

So the question is who has been playing with the production of hemp Crete
Any sop on making it ?
What’s the basis of hemp Crete polymers ?
Thx in advance

I see it posted on LinkedIn infrequently - if it comes back up again I’ll see if I can dig up some info

Four parts hemp hurd, one part lime binder, and one part water.

I really hope this catches on. A few years ago I read that of hemp has to be trucked more than 200 miles it was no longer a viable input. That’s was $2/gal ago. All I know is that concrete gets transported everywhere so I hope they can make it work.

Got a surprising quote the other day from the logistics company might be good data for figuring that out.

This time last year it cost us $2,300 to move a 53" trailer full of biomass half way across the country and now the cost is $2,500. When gas is nearly double I was expecting to get hit with around $4,000 a load. So all in all that’s a good thing as far as logistics costs.

So if the price for me is staying about the same I’d say it’s feasible for people to ship this stuff damn near where ever they want within the continental us.

Does that then need waterproofing?

I think , and I could be way wrong, that the Hurd is more abundant and easier to extract from European type hemp ie george Washington style hemp, not the bushy short plants grown for their cbd only
It’s a different type of plant like the way indica sand sativa a grow in general

It would be interesting to use it as a remediation technique for soil. If there’s soil that is concentrated in As, Pb, or Hg, perhaps it would deplete it and then sequester and dilute it into a strong, long term building material.

I know the Doguet family in TX farmed 20,000 acres for hempcrete. I don’t know how it all turned out. But I know the son of the family i can ask!

Had some friends build an off grid house out of it cause it was their dream . It turned out pretty cool but it was extremely labor intensive to make and rather costly after it was all finished. Took them multiple years to finish for a rather small off grid house . It was cool when finished but they had to jump through a lot of hoops to make it happen . They also did it totally off grid with budget constraints . It was expensive and hard for them to find the Hurd it was being sold as a replacement for traditional animal bedding for barns, coops , and etc. this was even in Oregon where you would think it would be easy to source back when hemp was even bigger and really blowing up

20 years ago I helped build a rather large house in the applaichain mountains using hempcrete as the insulation. Ive always been curious if its still there and how much carbon its soaked up by now. Havent seen many others ever attempt it. Was fairly easy paperwork wise then. I’ve also read about it being done out here in Hawaii before.

I’d really like to see it integrated into road technology. Im surprised with the single use plastic bans slowly making their way to every state and other countries if anyone will adapt a disposable hemp polymer to replace traditional plastic anytime soon. I think thats where the big money is at.

If I remember correctly maintaining roads and paving them is far more carbon and co2 emissions then the actual cars that are driving on them. I saw a more costly version of asphalt with hempcrete used ages ago that would at least be more environmentally viable long term.

Any papers on hemp polymers are welcome :grin:

Let’s talk. There is a production close to the farm.

I always thought that the hard part of making hemp plastic was the resins to hold it together.
