Hemp concrete has excellent thermal characteristics, providing optimal comfort in both winter and summer, enabling up to 70% heating savings (Cerema Study). It regulates humidity, improves indoor air quality and provides sound insulation thanks to the porous structure of the hemp shiv. Offering excellent fire resistance EI 240 (CEF Tests 2019), it also doesn't attract rodents.

Sourced from environmentally friendly cultivation, hemp-based materials are bio-based and renewable, offering innovative solutions for construction and renovation. The industry promotes short supply chains through proximity between producers and processing sites. Additionally, hemp materials capture CO2: 1 m² of 35 cm hemp concrete wall stores 38 kg of CO2, compared to 100 kg emitted by a concrete block wall with insulation.

Hemp concrete is made from certified hemp aggregates (shiv), a binder, and a small amount of water. It is used to create insulating walls and partitions in new construction or building renovation. As a lightweight material, it is easy to implement by filling a load-bearing frame, preferably wooden, either by wet process or dry process using prefabricated elements. Hemp concrete offers excellent seismic stability.

Hemp wool can be used in both renovation and new construction, in semi-rigid panels or rolls. It offers excellent thermal and acoustic properties. Thanks to its water vapor permeability, it regulates humidity and is rot-proof, contributing to its longevity and optimal indoor comfort. Easy to install and non-irritating, hemp wool is also resistant to insects and rodents, making it a sustainable and healthy solution for building insulation.

Hemp renders are generally composed of hemp shiv and a lime-based binder, with possible addition of other components to improve certain properties. These renders can be applied in thick layers for wall repairs. They significantly improve thermal and acoustic comfort. Their good water vapor permeability promotes the breathability of hemp concrete walls, essential for ensuring optimal humidity regulation and a healthy indoor environment.

The refining technique using short fibers, between 3 and 5 cm, called "cottonization," allows hemp to adapt to existing cotton production machines and to be blended with other fibers in varying percentages. This ease of industrial use interests major brands like Levis, Decathlon, or Ikea, which are developing hemp-based textiles to substitute more harmful fibers. This responds to consumer demand for more responsible clothing.

This innovative refining technique, in development phase, consists of producing hemp fibers of 20 to 40 cm to allow them to be transformed by wool refining tools. These fibers are used to manufacture 100% hemp yarns that are coarser for furnishing, luggage, and twine making.

The long hemp fiber refining technique follows the same process as linen, particularly using field retting, scutching, and spinning techniques to obtain 100% hemp yarns. Once woven, these yarns produce a natural fabric that will then be finished (dyed, printed) for use in the clothing or furnishing sector, thus creating a 100% hemp product.

This technique, used to produce textiles from wood cellulose like viscose or lyocell, has been developed for hemp using shiv in France since 2018. The main interest lies in its ability to provide versatile fibers with technical qualities such as fineness, strength, and lightness. Cellulosic hemp can replace petroleum-derived products for the production of textiles, clothing, or technical textiles.

These plastics are manufactured from compounds (composite granules) obtained by mixing hemp fiber with a polymer and additives. Melted and injected into molds, they allow the creation of complex and lightweight parts. They are used to produce dashboards and mirrors or, through extrusion, to produce long pieces: decking boards or window frame profiles.

Bio-based thermo compressed plastics are made from hemp fibers transformed into non-wovens using the carding and needling technique, mixed with thermofusible polymers. Once hot-pressed to obtain the desired shape, they are used in the automotive industry to manufacture lightweight parts, such as door interiors or trunk shelves.

Continuous fiber composite plastics consist of a matrix for cohesion, associated with fiber reinforcement, usually glass or carbon. Plant fibers bring new qualities: lightness, damping capacity, and aesthetics. For about ten years, products such as skis, surfboards, bicycles, helmets, tennis rackets, guitars, and luxury furniture have been incorporating these plant fibers.

Hemp seed, whether whole or hulled, has all the qualities of a health food. It is rich in protein, essential fatty acids, omega-3, fiber, copper, iron, magnesium, manganese, phosphorus, potassium, zinc, vitamins B1 and B6, and is also a good source of calcium.

Nutritional facts

Hemp oil presents an ideal lipid profile, rich in essential fatty acids such as omega-3 and omega-6, with a ratio close to 4:1. These polyunsaturated fatty acids help reduce cholesterol and prevent cardiovascular diseases.

Nutritional facts

Hemp seed, rich in protein (25% for whole seed and up to 60% in flours obtained from dehulled and defatted seeds), is one of the rare plants to contain all eight essential amino acids. This makes it an excellent plant protein, ideal for replacing animal proteins.
