Building With #Hempcrete 101
Hempcrete is used as a highly insulative wall material. It is a carbon-negative, natural, and lightweight construction material that provides highly efficient temperature and moisture control. It is also formable, dynamic, one-seventh the weight of concrete, and cures within hours.

Excerpt: "What Is in Hempcrete and Can I Source It Myself?
Hempcrete has three constituent parts: hemp, lime, and water.
Hemp, and Where to Source ItHere in #Australia, #HempShiv is only beginning to be farmed and brought to market. (A couple of notable enterprises being Hemp Homes Australia and X-Hemp in Tasmania where 80% of the hemp in Australia is currently farmed).
In Europe, a large industry is established and growing, with processing facilities in France, Holland, and Germany. The last house I built — working in Scotland — was made with Lithuanian hemp.
Over in the US, hemp production has exploded since the Agriculture Improvement Act or Farm Bill of 2018, finally allowing hemp cultivation after many, many years. [Alas, that is been severely curtailed. So much for Hemp For Victory]
The Binder
As you might assume, the binder is what binds the hemp shiv into a solid mass. The binder consists of either hydrated lime or natural #HydraulicLime. #HydratedLime (or air lime) has no impurities and is made by #kiln-firing limestone. The firing process removes the carbon molecules from the limestone and converts it into a dry powder. When you want to use lime as a binder or mortar, you introduce carbon dioxide again, essentially converting the lime back into limestone as it absorbs surrounding CO2. This is what’s known as the carbon cycle.
The other lime, hydraulic lime, is also kiln-fired using the same process. The difference being hydraulic lime has added or existing impurities known as #pozzolans."

So, if #GoatMilk isn't your thing, let's talk about #SoyMilk... A friend who is a #MOFGA-certified organic farmer and is #Vegan atttempted to grow soybeans in one of his fields. He said it was nearly impossible to grow them without pesticides, especially with #JapaneseBeetles here in #Maine. Sure, he used beetle traps, but a sex lure can only do so much -- beetles gotta eat! And as far as making one's own soy milk and tofu -- well, it takes almost a thousand soy beans to produce a small block of tofu (and if you do it right, you'll end up with some soy milk to drink). So, if you want to give it a go, I'd say try growing a dozen or so soybean plants, harvest the soybeans, then make your own tofu and soy milk (you'll probably just end up with one batch). And I'll tell you -- the stuff made from freshly grown, organic soybeans has a delightfully nutty taste that you don't get with most of the commercial stuff (I haven't found any that compares to the homemade stuff).
That being said, I will be posting about #GrowingSoybeans, #HarvestingSoybeans, and making #Tofu and #SoyMilk at home for a bit, before finishing up with articles about #HempCrete. Stay tuned...

Uh-Oh! 🧵 (long term test of #hempcrete blocks, industrial and DIY)

So, while #HempWool has some advantages over #Fiberglass and insulation made from #SyntheticMaterials , it is not fireproof (unlike #WoolInsulation), and requires treatment to make it fireproof. The same with mildew/mold resistance (treated with lime plaster or other materials). I've also seen "hemp wool" mixed with synthetic fibers, so that kinda defeats the purpose of using natural fibers (imho). Plus, I'm not finding any instructions on how to #DIY hemp wool (unlike wool insulation or #Oakum).
Why Hemp Wool is Gaining Traction in Sustainable Construction
Published by naturalbuildingaustralia on 14/02/2025
"As an all-natural material, it’s increasingly being considered for use in construction projects aimed at reducing environmental impact and improving energy efficiency.
Hemp wool is essentially insulation made from hemp fibers and is commonly found in eco-conscious building projects. While Harry Hemp’s blog doesn’t refer to any specific vendor or product, it highlights the general benefits and concerns surrounding hemp wool as a material in modern construction.
However, there are valid concerns, especially when it comes to untreated hemp wool. Fire safety and mold resistance are two issues that need attention before this material can be fully integrated into permitted builds. These concerns stand in contrast to the proven advantages of #hempcrete, a material that has already set a high standard for sustainable construction.
Benefits of Hemp Wool
Hemp wool, made from the fibers of the hemp plant, offers several key advantages:
- Thermal Insulation: Hemp wool provides excellent R-values, helping to regulate indoor temperatures and reduce energy consumption.
- Sound Absorption: This material excels at reducing noise pollution, making your indoor environment quieter and more comfortable.
- Eco-Friendly: As a renewable resource, hemp wool sequesters carbon during production, helping to reduce its overall environmental footprint.
- Health Benefits: Free from chemicals and toxins, hemp wool is non-allergenic and contributes to better indoor air quality.
These qualities make hemp wool an appealing alternative to more traditional insulation materials like fiberglass and mineral wool. It’s a natural option that supports sustainable living while offering practical benefits.
Challenges with Untreated Hemp Wool
While hemp wool offers many advantages, untreated versions come with their own set of challenges that must be addressed:
Fire Safety Concerns
Untreated hemp wool typically has poor fire resistance, which disqualifies it from use in many permitted builds. Building codes often require materials to meet specific fire safety standards, and without proper treatment, hemp wool doesn’t meet these requirements, potentially posing a risk to safety.
Mold and Mildew Issues
Hemp wool’s natural fibers can absorb moisture, leading to potential mold and mildew growth in environments with high humidity or poor ventilation. This is a stark contrast to hempcrete, which naturally resists mold and moisture, making it a more reliable choice for durable and safe construction.
How Hempcrete Stands Up
While hemp wool has its potential, hempcrete is already a well-established material in sustainable construction.
Here’s how hempcrete stacks up in comparison:
- Fire Resistance: Hempcrete boasts excellent fire ratings due to its lime-based composition, making it compliant with building codes and safe for use in construction.
- Moisture Control: Its unique ability to absorb and release moisture without compromising its structure makes hempcrete highly resistant to mold and mildew.
= Durability: Hempcrete is naturally resistant to pests, mold, and moisture, making it a long-lasting material in construction.
- Code Compliance: Hempcrete has undergone rigorous testing and meets ASTM standards, ensuring its reliability in meeting building code requirements.
These characteristics make hempcrete a top choice for builders looking for a safe, sustainable, and code-compliant material.
The Future of Hemp Wool
The future of hemp wool is promising, especially as advancements in testing and treatment could resolve its current limitations.
Improved Fire Resistance
Through treatment, hemp wool can be made fire-resistant, meeting the stringent requirements for modern builds. This will make it a much safer option for both builders and homeowners.
Enhanced Mold Resistance
New techniques in moisture management could prevent mold and mildew from forming on hemp wool, making it more reliable and long-lasting, even in humid climates.
Conclusion: The Potential of Hemp Wool in Sustainable Construction
While untreated hemp wool still has hurdles to overcome, its potential as a sustainable, eco-friendly building material is undeniable. As advancements in fire resistance and moisture management continue, hemp wool will become a viable option for modern construction, alongside its proven counterpart, hempcrete.
The combination of both materials offers a powerful solution, balancing insulation and structural integrity, and paving the way for greener, safer, and more sustainable construction practices. As the industry continues to innovate and test new methods, the excitement surrounding hemp wool is justified—it’s on the path to becoming a staple in eco-conscious builds worldwide."

The buildings constructed from #cannabis
Francesca Perry, 18 June 2023
Excerpt: "In search of #sustainable materials, architects are turning to an unusual source: #hemp.
"Surrounded by verdant fields, Flat House, which sits on a farm in Cambridgeshire, the UK, looks like a typical barn conversion. But inside, the look and feel of the building immediately make you realise this is something quite different. 'The walls remind me of hay bale dens we used to make as kids,' says Flat House's owner Gemma Barron. 'It has the most lovely acoustic quality. And last year we had the heating off for 24 hours in mid-winter and it stayed warm.'
"What makes this bright, airy and comfortable home unusual is the material used to build it: hemp. While we may be more familiar with the cannabis plant's association with the psychoactive substance cannabis, and its use in health supplements and textiles, hemp is rapidly becoming a sought-after sustainable construction material.
"The fast-growing plant is a renewable resource, with carbon-capturing properties. When used in building, it typically takes the form of 'hempcrete' (also known as lime hemp concrete), a sturdy material made by mixing #HempHurd – the woody core of the plant – with a binder made from water and lime. Hempcrete has a high thermal mass, making it an ideal insulation material which improves the energy efficiency of buildings and reduces greenhouse gas emissions over time. It also continues to absorb carbon over its lifespan.
"Sustainable materials are in high demand as the construction industry seeks to decarbonise. Buildings and construction are responsible for approximately 37% of energy and process-related global carbon dioxide (CO2) emissions. This is due to the industry's heavy reliance on fossil fuels, including carbon-intensive materials such as concrete, steel and glass, as well as the greenhouse gases emitted in heating and cooling our buildings."

Nine buildings constructed using #hemp show the biomaterial's potential
Nat Barker | 6 January 2023
Excerpt: "Hemp is becoming an increasingly popular material among architects seeking to reduce the carbon impact of their projects. Here is a roundup of nine buildings constructed using the versatile cannabis crop.
Mounting evidence suggests that the construction industry must adopt bio-based alternatives to common carbon-intensive building materials, such as concrete, to play its part in reducing emissions and limiting global temperature rises.
One such alternative gaining increasing attention is hemp, the fast-growing cousin of the marijuana plant that is already widely used as a biofuel and textile.
Cambridge University researcher Darshil Shah previously told Dezeen that hemp can capture atmospheric carbon twice as effectively as trees.
In buildings, it is often used in the form of hempcrete – a composite of hemp fibres and lime that is durable, highly insulating and mould-resistant.

Excerpt: "Hemp is becoming an increasingly popular material among architects seeking to reduce the carbon impact of their projects. Here is a roundup of nine buildings constructed using the versatile cannabis crop.
Mounting evidence suggests that the construction industry must adopt bio-based alternatives to common carbon-intensive building materials, such as concrete, to play its part in reducing emissions and limiting global temperature rises.
One such alternative gaining increasing attention is hemp, the fast-growing cousin of the marijuana plant that is already widely used as a biofuel and textile.
Cambridge University researcher Darshil Shah previously told Dezeen that hemp can capture atmospheric carbon twice as effectively as trees.
In buildings, it is often used in the form of hempcrete – a composite of hemp fibres and lime that is durable, highly insulating and mould-resistant.

#Hemp cultivation contributes to the European Green Deal objectives
Excerpts:
"Hemp has a number of #Environmental benefits.
- #CarbonStorage: one hectare of hemp sequesters 9 to 15 tonnes of CO2, similar to the amount sequestered by a young forest, but it only takes five months to grow.
- Breaking the cycle of diseases: hemp helps to break the cycle of diseases when used in #CropRotation. In addition, weeds are not able to grow due to the fast growth and shading capacity of hemp plants.
- #SoilErosion prevention: dense leaves of hemp become a natural soil cover, reducing water loss and protecting against soil erosion. Hemp covers the ground just three weeks after germination.
- #Biodiversity: flowering cycle usually occurs between July and September, coinciding with a lack of pollen production from other crops. Hemp produces large amounts of pollen. It also provides shelter for birds and hemp seeds are a food for animals.
- Low or no use of #pesticides: hemp is susceptible to few pests because of the lack of natural predators, which means that the use of #insecticides, #herbicides, and #fungicides can be avoided in most cases."
"Uses of hemp1. Textile industry (#HempFibre)
Hemp fibre is very similar to linen and the interest of the textile industry in using hemp fibre is growing. The European Commission, in its circular economy action plan, considers the textile sector as one of the cornerstones in the transition towards a greener and more sustainable economy and it has encouraged stakeholders to seek new materials and new economic models. To this end, the EU has adopted a strategy for sustainable and circular textiles aiming to create a more sustainable, innovative, circular economic model.
Hemp fibre and textile material
Hemp fibre is a sustainable raw material for the textile industry.2. Food and feed (#HempSeeds)
Hemp seeds contain high levels of protein and considerable amounts of fibres, vitamins, Omega-3, and minerals. As a result, de-hulled hemp seeds serve as a food for human consumption, while whole hemp seeds are used as feed for animals.
3. #Construction (#HempFibre)
There are three main hemp-based products used in construction: #lime hemp concrete (#hempcrete), #HempWool, and fibre-board insulation. The construction sector is responsible for 40% of energy consumption and 36% of GHG emissions, and 75% of that energy goes to waste. This has led to a search for construction practices and materials that are carbon neutral or carbon sequesters. Hempcrete is a carbon sequester as the amount of carbon stored in the material is higher than the emissions generated during its production, and it continues to store carbon during the building’s life. Improving energy efficiency in the building sector will play a key role in achieving carbon-neutrality by 2050, a goal set out in the European Green Deal. Hemp can play a significant role in reaching this objective.
Hempcrete, hemp wool and fibre-board insulation are used in the construction sector due to their energy efficient properties.
4. #Paper production (hemp fibre)
There are multiple advantages to using hemp fibre to make paper: hemp stalks only take up to five months to mature, #HempPaper does not necessarily require toxic bleaching chemicals and hemp paper can be recycled seven to eight times.
Hemp fibre paper is a more sustainable alternative to paper made from wood pulp.
5. Other uses
Hemp-derived products are used in different industries and for different purposes. Negative environmental effects of plastic have pushed manufacturers to seek alternatives. Hemp is a good option given its light weight and durability. As a substitute for plastic, hemp-derived products are used in different sectors such as car manufacturing, railway, aviation and aerospace.
Other uses of hemp include #cosmetics (oils, lotions, shampoos, etc.) and energy production (#biofuels). There is also interest in the production and marketing of hemp extracts, notably cannabidiol (#CBD), due to its possible uses in cosmetics, health products and food. These possible uses are, however, subject to the relevant EU requirements. In November 2020, the Court of Justice of the European Union determined that the marketing of legally produced CBD is permitted under EU law."

Got a tour of the neighbours project today. They're building a hexagonal house, timber framed with straw for insulation and hempcrete sprayed on that. Interesting stuff!
It sits on large fieldstones, one in the center and one for each corner.
Hope they get a roof on there before the cold comes.

Interesting to see #hempcrete being used in combination with a metal frame in Bangkok,Thailand by hempire. Typically you would use wood, not just for emission reasons, also for rust issues. What do you think is better in this very humid climate? www.linkedin.com/posts/sergiy...

☝🏽🧵quick update on the #hempcrete block long term durability 'test'. Take a look at the green roof while we are at it.
