Good delivery of information, i found that useful, lots of positives in this product, would be great to see it used in a free flowing way where a designer uses curved walls.
You say that this material is carbon-negative, but this seems hard to reconcile with the huge CO2 cost in making the lime. Depending on kiln efficiency, a Kg of lime requires some 5MJ of energy to manufacture, which is usually sourced from burning of coal.
I was reading something recently, I think, where someone commented that the lime being used is not the same and doesn’t require as extensive processing. I’d share the source if I could remember. Maybe try looking it up. In reality no resource, building material, energy source, is without some kind of challenge to our environment. A balance needs to be considered. Nothing is going to be some idea-illogically perfect. And trees feed off carbon. 💝 “Look deep into Nature and then you will understand everything better.”-Albert Einstein. 💝🌈

what does a house like that size cost in total? euros ?
Why aren’t all houses made out of this??? No down sides in the grand scheme of the planet! If it was even double the price, if it was more accessible and popular it would be pennies.
Sitting here in 2022 and wondering to myself with the rising costs of building materials here in New Zealand is it still 10% to 15% more or is it now in fact cheaper? also thank you for this very informative video into a wonderful product
Lockie ...... MIHARO RAWA ATU .... OK. ITS A DATE. ONE DAY YOU COME BUILD OUR TUHOE HOMEGROWN HAND BUILT HEMP HOME. THE DAY IS COMING....NĀ MIHI LOCKIE 🌿
why not build the walls on the floor, cladding down first, build the frame,...............then, pour over the hemp-crete, and can pack the whole wall simultaneously, with larger utensil.................i bet this method, tweaked, could provide a much more like-application of material, as well as be much faster, easier to clean, etc...................like pre-fab
I have seen a number of videos on hempcrete, seems like it should be used way more. There are also prefab blocks and even whole prefab walls then can be delivered to the site. One fact that was mentioned here seems not quite correct though: Can hemp really absorb the same amount of carbon than a pine plantation in 20 years? I mean those trees have a lot more biomass than the hempplants so that cant be right...
takes 3 months to grow. so over 20 years depending on the location 3 harvests are possible per year . x 20 years. Per square meter its 4 to 8 times more than trees. In the mean time, super strong fibers, housing insulation and blocks, paper, 20% stronger than oak wood layers, bioplastics, fuels, oils. animal feeds, fertilizers and a super food from the seeds too. What you can make from it vastly out weights trees without screwing up the environment. It uses little complex fertilizers and pesticides as well. It was banned not because of drug usage but because it had that many uses as well as some medical use as well.The few assholes could not control said plant so they made up a load of horseshit instead. It also means communities across the world are minimal in debt to output. Sustainability 100%. Free the weed!
@@jammapcb Thank you for the infos, I have long been a fan of hemp. Hempcrete still uses a certain amount of lime binder (which is some sort of concrete really) which does take some CO2 in production. On the other hand I just learned about a tree named Paulownia which can grow to full height in only 10 years, so that also pretty good. Many great possibilities to capture carbon.
WOW Lochie!! Beautiful work!! Had we known how good you are, we would've chosen a house addition instead of the LOX shed extension ;) Keep up the good work and best of luck! Come back to Colorado any time, mate :)
