Once the areas major agricultural product, hemp is making a comeback in the Altiplano section of Granada, Spain. Until the late nineteen sixties industrial hemp growing formed the backbone of this wholly agricultural section of Spain. Towards the finish of the Franco era, with the invention of nylon and the mechanisation of agriculture most of the population was forced off the land to get work on the coast and major cities.
With the advent of the eco-age the curiosity about industrial hemp will be revived since it is just a major constituent of eco-bricks, an essential part of sustainable housing.
Hemp comes from the Anglo Saxon word’haemp’and is the popular name for plants of the cannabis genus. Hemp usually describes the strains of the plant cultivated just for industrial use rather than cannabis that is related to pot and similar drugs.
Hemp has a huge number of uses but remains overshadowed by the cannabis connotation of illegal drugs, with which it’s often confused. However hemp can legally be grown, under licence, in several countries, such as the European Union countries and Canada.
Cannabis sativa L. could be the variety primarily grown for industrial purposes, it is just a fast growing plant and has been cultivated for several thousand of years being used to produce rope, clothing, paper, hemp oil and medicines. Growing hemp improves the condition of the ground and reduces ambient contamination. It is a robust plant that requires neither herbicides nor pesticides during its cultivation.
Hemp as a professional material has a ten thousand year history. The initial recorded utilization of hemp was as a material fabric, within China as far back as 8000BC.C. Circa 4000B.C. hemp grew to become used, again in China, to produce ropes and as food. 2000 years later, the Chinese hemp oils and medicine were in use. By 1000B.C. its use had spread to India and Greece where the initial cases of hemp paper were found.
By the 6th century hemp was being utilized in Europe in some amazing ways, in France a hemp reinforced bridge was built and it’s still used today. The hemp fibre also found uses in sailmaking, caulking materials, fishing nets and lines. In later years hemp was used to produce a variety of foodstuffs including butter and beer. By the 15th century Renaissance painters were utilizing hemp canvases.
Today industrial hemp can be used to create a staggering number of products ranging from medicines, body care products, building and insulating materials, clothing, textiles, food, fuel, livestock food and bedding, plastics and paper.
In the building industry hemp bricks, because of their sustainability and excellent insulation properties, are now being used to create external and internal walls of ecological homes. Of this type of Spain the external walls of an eco house will contain a eco-bricks, stated in Guadix with the proprietary name of Cannabric® ;.
Cannabric® derives its properties from industrial hemp fibres (cáñamo). The hemp bricks are comprised of industrial hemp fibres, slaked lime and a combination of innert mineral materials. The bricks combine the functions of lots bearing wall that is fire-resistant and does not require the addition of thermal or acoustic insulation. how to take kratom
The most important part of the eco-brick is industrial hemp which has a really low thermal conductivity (0.048W/m²k) producing a brick with vastly superior insulation properties against both cold and heat. The mineral part of the bricks gives them their mechanical strength. Being a solid brick, with a higher specific heat, it’s the perfect thermal properties to protect against heat.
