Discover the many reasons why hemp is a valuable ally in regenerating the planet.
Origins and History
Archaeological research has discovered pieces made of hemp dating back to 12,000 BP (before present) in regions where China and Taiwan are today, leading many scientists to conclude that this may have been the first cultivated plant. in the history of humanity , thanks to its versatility: our ancestors and the generations that followed were always able to use it as a raw material to produce food, medicine, fabrics, ropes, paper and structures suitable for construction.
In the 1930s, political and economic interests led the United States to ban the cultivation of the entire Cannabis family without distinction -- which ended up eliminating the planting of hemp not only in the country, but throughout the world, for decades on end.
From the Cannabaceae family, the plant's scientific name is Cannabis, although it has different variants (wild or cultivated) and is generically called hemp or hemp.
- The terms marijuana or marijuana are directly associated with variations that have a concentration of more than 30% THC, or Tetrahydrocannabinol, the psychotropic active ingredient found in these Cannabis.
- Hemp or hemp are the generic nomenclatures (recognized by the 2018 North American legislation) that classify another variant, with less than 0.3% THC in its composition.
What the two variants have in common are high levels of CBD, Cannabidiol, a non-intoxicating component.
Super soil regenerator
Carbon molecules found in hemp stems prove its powerful ability to absorb CO2 : each hectare of area covered by the plant is capable of eliminating 22 tons of carbon dioxide from the atmosphere annually.
As it is possible to have at least two harvests of the plant per year, this bill can double. Fast-growing, hemp reaches four meters within 100 days of planting, making it one of the most efficient alternatives for converting CO2 into biomass .
Although its characteristics are typical of annual cultivation, it also works as a perennial crop, with deep roots that prevent erosion. Hemp adapts to a multitude of soil types and climatic conditions, in addition to requiring very little care and consuming little water.
It is used to cover and recover soils depleted by monoculture or degraded by chemical products, preparing the land for planting other crops and eliminating the need for the use of artificial fertilizers.
Its filtering capacity is so great that it was used to eliminate radiation hotspots in Ukraine caused by the Chernobyl disaster. This process of eliminating toxins from the land and recovering it from pests and other evils is called phytoremediation .
Many qualities and benefits
Hemp sprouts are rich in canflavin A and canflavin B, natural anti-inflammatories 30 times more powerful than aspirin , which makes hemp an ally in the treatment of chronic pain and muscle regeneration.
CBD-based oils and medicinal products have been widely used to treat the effects of severe pathologies, such as epilepsy and cancer, to mental health problems such as insomnia, anxiety and depression .
Also considered a superfood, it is a source of protein for both humans and animals. The amino acids contained in its seeds are comparable to those present in beef or lamb: 30 grams of hemp seeds provide 11 grams of protein.
With a flavor similar to chestnuts and almonds, its sprouts are rich in good fats, such as omega 3 and omega 6 , and can be consumed in salads, pizzas and smoothies, and can be sprouted at home.
Innovative Uses
There are around 25,000 different uses for hemp. Large companies are already using bioplastic from hemp for packaging, 3D printing and in the automobile industry. Its fibers have a wide spectrum of applications in the textile and paper industry, and as biofuel. In civil construction, hempcrete, or hemp concrete, has been a sustainable and resistant alternative, as well as non-toxic and breathable.
Hempcrete, hemp concrete
The name is a mixture of the words hemp and concrete , which are, respectively, hemp and concrete in English. Hempcrete, a sustainable innovation in the field of construction, has gained prominence as an ecological and efficient alternative to traditional materials. Composed primarily of hemp fibers, lime and water, Hempcrete offers a unique approach to building sustainable structures. This compound creates a lightweight, porous and highly insulating material, ideal for applications in construction.
Hempcrete is used as an eco-friendly substitute for traditional concrete in a variety of applications, from walls to thermal and acoustic insulation. Furthermore, it contributes to reducing the carbon footprint in construction, as the hemp plant absorbs CO2 during its growth.
The process of using Hempcrete involves mixing hemp fibers with lime and water, forming a moldable mixture that can be applied directly to the desired structures. After drying, Hempcrete forms a solid, insulating structure.
Benefits and Differentiators:
1. Environmental Sustainability: Growing hemp is considered more sustainable compared to other building materials as the plant grows quickly and requires fewer pesticides.
2. Thermal and Acoustic Insulation: Hempcrete offers excellent insulation properties, maintaining internal temperature and reducing noise transmission.
3. Lightness and Durability: Despite being light, Hempcrete exhibits surprising durability, providing a resistant and efficient construction.
Cotton and Hemp Fiber Fabric
Hemp fiber , extracted from the stem of the hemp plant, is known for its durability and strength. Its cultivation requires less water and pesticides compared to other fibers, contributing to a reduced ecological footprint. Additionally, hemp is a fast-growing plant, providing a renewable source for the production of sustainable fabrics.
Cotton , one of the most traditional fibers in the textile industry, offers a soft and comfortable touch to fabrics. By opting for organic cotton , grown without the use of pesticides and harmful chemicals, we embrace a more environmentally friendly approach. Sustainable cotton promotes responsible agricultural practices, ensuring the preservation of soil and biodiversity.
Harmony between Hemp and Cotton
The blend of hemp fiber and cotton results in fabrics that offer a soft, lightweight feel, promoting breathability and comfort throughout the day. The strength of hemp combines with the softness of cotton, creating fabrics that last longer, reducing the need for frequent replacements. The choice of hemp and cotton fiber fabrics reflects a commitment to environmental sustainability , supporting conscious agricultural practices and minimizing negative impact on nature .
This versatile combination of natural fibers can be found in a variety of garments, from t-shirts and blouses to pants and accessories. The harmony between hemp and cotton provides a classic aesthetic with a modern touch , suitable for different styles and occasions.
This sustainable partnership represents a significant step towards a future of fashion that prioritizes the balance between style, comfort and environmental responsibility .
