Industry
Hemp has over 25,000 known uses including textiles, composites boards, cosmetics, paints, insulation, construction materials, sunscreen, paper, instrument bodies, plastics, food and medicine.
The hemp plant's stalks are made up of two layers: an outer layer of rope-like bast fibers and an inner layer of woody pith. For textile purposes, only the outer bast fiber layer of the Cannabis sativa stalk is used, while the inner woody layer is typically used for fuel, building materials, and animal bedding.
Hemp fibre is the strongest natural fibre known, weight for weight stronger than steel.
Construction
Hemp is becoming an increasingly popular material in the construction industry due to its sustainability, strength, and versatility.
Key uses for hemp in Construction include:
-
Hempcrete is a bio-composite material made from the inner woody core of the hemp plant mixed with a lime-based binder. It is used for construction and insulation purposes. Key benefits include:
Insulation: Excellent thermal and acoustic insulating properties as well as being air tight allowing it to meet todays building standards.

It’s lightweight, insulating, breathable, and fire-resistant — an innovative and sustainable alternative to traditional construction materials like concrete and brick.
Carbon Capture with Hempcrete
Hempcrete is a natural carbon sink. Hemp plants absorb CO₂ as they grow, and when processed into hempcrete, that carbon stays locked in the material for over a century making it highly efficient for Carbon Capture. Compared to high-energy solutions like DACCS (Direct Air Carbon Capture), hempcrete offers:
Low cost per ton of CO₂ removed
Minimal risk of reversal
High scalability with ecological co-benefits
By building with hempcrete, we can help transition the construction industry — which is responsible for 11% of global emissions — toward net-negative emissions.
Built-In Strengths
Hempcrete walls are durable and safe:
Does not rot even when wet due to breathability and antifungal properties
Fire-resistant, forming a protective char layer under extreme heat
Pest-resistant and long-lasting
Recyclable and Compostable
At the end of its life, hempcrete can be:
Crushed and reused in new hempcrete mixtures
Composted, returning carbon to the soil
Repurposed for future eco-friendly construction
This circular lifecycle supports a regenerative economy.
Aligned with Global Sustainability Goals
Hempcrete contributes to several UN Sustainable Development Goals (SDGs):
SDG 6 (Clean Water) – minimal water use, low water pollution
SDG 7 (Clean Energy) – requires no energy-intensive processing
SDG 8 (Decent Work & Economic Growth) – promotes circular economy jobs
SDG 9 (Industry & Infrastructure) – replaces high-impact building materials
SDG 15 (Life on Land) – restores ecosystems and protects biodiversity
Sustainable From Seed to Structure
Hemp cultivation supports regenerative agriculture:

Plus, hempcrete is made from rapidly renewable, locally sourced materials, reducing dependency on scarce resources like sand and limestone.
Hempcrete Carbon Credits
Hempcrete now qualifies under carbon credit systems thanks to:
Its biogenic carbon capture and long-term storage
Built-in permanence and additionality
Cost-effective carbon removal at just $70–$75 per ton CO₂ (2023–2024 averages)
These credits make it financially viable to scale up hempcrete use — crucial for green building projects.
Textiles
Hemp textiles refer to fabrics and products produced using the fibres from the hemp plant. Hemp has a long history of being used in textiles dating back 4,000 BC in China with some of its earliest known uses.
Hemp has many characteristics which make it ideal in textiles:
-
Hemp fibers are naturally long, strong, and tightly woven, making them highly resistant to wear and tear. Garments and fabrics made from hemp last significantly longer than those made from cotton or synthetic fibres, getting softer with every wash without breaking down.
-
Low water footprint: Requires up to 4x less water than cotton
Minimal chemical use: Grows well without synthetic pesticides or herbicides
Improves soil: Hemp’s deep roots reduce erosion and remediate contaminated soils (phytoremediation)
Fast-growing: Can be harvested in just 3–4 months, allowing for multiple crops per year
Hemp is also biodegradable and supports circular fashion initiatives.
-
Modern processing methods create hemp fabrics that are soft, breathable, and hypoallergenic. Hemp naturally wicks moisture away from the skin, making it ideal for activewear, bedding, and summer clothing.
-
Hemp fabric provides excellent thermal insulation keeping the wearer’s temperature well regulated in all seasons
-
Mould & mildew resistant, extending garment life and reducing odor
Naturally UV-resistant, blocking up to 95% of harmful UV rays — great for outdoor clothing

Hemp Textiles Compared to Cotton and Polyester:
As sustainability becomes central to global fashion and manufacturing, hemp is experiencing a renaissance. It is now a key player in the eco-textile movement, supported by consumer demand and environmental policy shifts.
With the right processing technologies and market support, hemp has the potential to rival cotton in scale while far exceeding it in environmental performance.
Biochar
BioChar is a high-carbon charcoal created through the pyrolysis of biomass waste — a process that locks in atmospheric carbon for 100 to over 1,000 years. But it’s more than just carbon storage: BioChar boosts soil health, supports sustainable agriculture, and enhances material performance across industries.
It’s a nature-based solution with tech-grade reliability, turning waste into value while capturing carbon permanently.
BioChar is produced using a pyrolyser, which heats biomass in the absence of oxygen. This transforms waste into stable carbon and syngas — the latter can be used to generate energy, improving overall efficiency.
Cheap pyrolysers often yield poor results. Augur Associates supports clients in sourcing and financing high-quality systems, often funded through early carbon credit agreements.
Applications of Biochar
-
Hemp biochar can be used as a soil amendment to improve soil health, retain nutrients and balance PH making it more suitable for various types of crops..
Hemp biochar can facilitate healthier plant growth through enhancing soil structure, increasing water retention, and improving aeration
It can help retain nutrients in the soil, reducing the need for chemical fertilizers and preventing nutrient leaching.
-
By storing carbon in a stable form, hemp biochar can help in reducing the overall carbon footprint, contributing to climate change mitigation efforts.
-
Hemp biochar can absorb heavy metals and other contaminants from the soil, making it useful for soil remediation projects. It can be used in water filtration systems to remove impurities and contaminants from water sources.
