Looks interesting in theory but as with any plant based alternative to an industrial scale problem, the question is, where do we plant it ? It's the same problem we are facing with bio fuel. Technically we can make it but right now most of the land suitable for growing crops is being used for food. Should dial down on the corn ? Wheat ? Or just cut down more trees ? Any of those solutions isn't really one as you're replacing one problem with another. Cut down on food and you get a food shortage, cut down the trees and you're suddenly absorbing less CO2 and killing even more of our ever shrinking forests. Sure there are partial solutions as lowering food wastes and as such lowering our food needs but with an ever growing population that's not really a long term solution. On another hand concrete is mostly made out of minerals that we extract from mountains (limestone) in places we usually can't really grow anything. The same (main) reason why fossil fuels are used over bio fuels (as lobbying and corruption is also defiantly a thing but off topic here).
My issue with this is not the material in itself as it has great merits and should definitely be an alternative building material for all the mentioned reasons in this video especially insulation but I'm having an issue with us wanting to completely replace concrete with hempcrete as I don't see how we can realistically do this for all our construction needs. And we need so much of it, every day, in every city of the world.
On a broader topic this is also why I'm skeptical about most "eco friendly" solutions people tend to present. If scaled up to the whole world it's in most cases not realistically feasible without us sacrificing other things and making potentially worse ecological problems. They just don't see the big picture.
In the end it comes down to a very simple fact, there are just to many of us and we're past a point where our society can live without negatively impacting the environment. Global warming is inevitable, deforestation is inevitable, some form of environmental pollution and destruction is inevitable. Accept it as a fact and let's try thinking of ways to minimize the damage we do until science advances far enough for us to overcome them. As such, replacing all of our concrete production with hempcrete is definitely not it.
Hemp could be used and change so many industries, making it easy and cheap to produce clothing, building materials and many more locally killing all those giant corporations that makes profit on slavery while destroying our planet along with the process. That is why it's so illegal even where it's decriminalised, not because of it's drug use prosperities (but those are also hated by pharma cuz might help, where things that don't but make profit, won't)
The issue many will have is the vehicles and facilities CO2 emissions. You can never make these people happy. Furthermore it is a very very weak material. You cant deny that. Its just not probable to assume it is a safe housing material. Even with concrete or wood we have to put propper framing and foundations to it with wires and some metal poles. Its definitely not a solution for home materials. Maybe for outside floor material but nothing more. The way this author advertises it is as if they are good housing materials which just isnt the case.He just wont stop talking about the use for houses. Its just not true.
The idea is to make houses last longer, not be able to pick them up and move them somewhere else. That is actually crazy. You're idea of stability and enduring materials is not even have things built into the foundation. You are insane. Stability is good for the society, because instead of treating humans like a strip mine, you make it less convenient to uproot them over and over. STOP MAKING VIDEOS LIKE THIS. STOP BEING LIKE THIS. JUST STOP.
Interesting video but have to point out that hempcrete is not intended to replace concrete at all…. This is a common misconception that is erroneous. Hempcrete is an infill system, not a structural system. In comparison to a conventional wall it would be far more accurate to say that hempcrete plus finish lime plaster could replace: exterior paint, exterior siding, weather resistant barrier, ply wood, insulation, drywall, and interior paint. It still requires some other form of structure to support gravity and lateral loads and acts very differently from concrete (which is structural but has almost no insulation value.) I am an architect and I design hempcrete homes and it’s well known in the hempcrete community that hempcrete is not a replacement for concrete, that’s why a lot of us call it hemp-lime. There are people manufacturing blocks but again those are primarily intended as infill elements not structural ones, some structural blocks are being manufactured but those contain some other structural element.
jesus … i have a question… did you ever challanged your view on this CO² nonsense? did you ever really researched the topic or are you just repeating what "scientists" promoted by the goverment say? did you know that the world is 15% greener since the year 2000? did you know these things called turbo greenhouses in which they create a CO" ENRICHED Athmosphere so that the plants grow faster and bigger?
i support everything reducing garbage and increasing the usage of natural materials instead of chemicals…. but this CO² nonsense is so stupid its not even funny anymore.
What a crap comparison. You can not compare concrete ( static building supply ) against hempcrete, a damping material like styrofoam or stonewool. That is bullcrap. Neither of those can substitute the other.
So you see. Climate change is being solved by the free market because their is a demand for it. You don't need to vote democrat to solve climate change
For the simple fact that hempcrete is not readily available I would expect many builders who use this product will skimp on the amount necessary to achieve its full potential for what ever reason a person decides to use it. While charging you for a top quality job. One would need an inspector to make sure it is being used in the correct amount. Meaning more costs.
I skipped a little ahead as many people do, and all of a sudden there is marijuana. Then there is talk about hempcrete usage as INSULATION. We don't use concrete as insulation.
How well would Hempcrete work as a full or partial replacement for concrete in Rammed Earth construction? It seems to me, in my uneducated opinion on the subject, like it would be a poor substitute.
There's a lot to why we aren't going to see more hemp products, The biggest reason is big companies. That's the whole reason pot got outlawed was because lumber companies were worried that hemp would take over so they started spewing propaganda against it
The best way to make an alternative solution is using hemp-reinforced compressed 'earth create' panels which should be reinforced using an SS square pipe frame.
This panel can be plastered using gypsum and it will last a century or more than a century for sure.
Raw earth is fire-resistant and porous. By adding lime and hemp fibers to it then it will become highly strong and even bulletproof. If you add 10 percent of cement to it then this will get even stronger.
These panels are the best way to make sustainable buildings and since these are wall height it will be easy to erect a single-story building in a day.
Time and Labor cost a lot in building a home. This will be the best alternative for this.
My suggestion is hemp-reinforced earthcrete panels with steel reinforcement.
marijuana is a made up name, the government came up with to make it sound racially motivated toward hispanics. Its a Cannabis plant, and what you smoke is the flower.

You could probably build a sturdy structure out of the weed I used to get in high school.

Could this be used as like the space shuttle heat shealds am only 2 mins in ??

Your dog will get murdered for having this in your home
You guys know plants use CO2 like we use O2, right?

I plan on starting my hemp house this year. I'll be documenting the entire process. Starting from seed, to plant, to hurd.
While the plants are growing, I'll be falling trees on the property and milling them into lumber on site.
I know someone who has gone to do her PhD in the use of hemp in sustainable development. It's an exciting time

R.I.P. overpriced hemp crete

"How this plant could replace concrete"
Answer: It can't.
I skipped a little ahead as many people do, and all of a sudden there is marijuana. Then there is talk about hempcrete usage as INSULATION. We don't use concrete as insulation.
How well would Hempcrete work as a full or partial replacement for concrete in Rammed Earth construction? It seems to me, in my uneducated opinion on the subject, like it would be a poor substitute.
Sounds like mostly just an insulating product. You didn't do a comparison to other insulating
"net zero future." I'm curious as to what you and the WEF plan to do about India and China. Ecofacism is going to be fun.
How does it handle tornadoes tho?
they could raise the t.h.c to 6 % and be more true to science and not get high
literally rolled up 2 watch this
There's a lot to why we aren't going to see more hemp products, The biggest reason is big companies. That's the whole reason pot got outlawed was because lumber companies were worried that hemp would take over so they started spewing propaganda against it
I can tell this man doesn’t smoke lol the way he was like “I’m getting the munchies”
What’s better during tornadoes and hurricanes?

Time and Labor cost a lot in building a home. This will be the best alternative for this.

Net zero is impossible and will lead to the downfall of society
marijuana is a made up name, the government came up with to make it sound racially motivated toward hispanics. Its a Cannabis plant, and what you smoke is the flower.
What if bugs eat it
