When the areas major agricultural product, hemp is building a comeback in the Altiplano area of Granada, Spain. Before late nineteen sixties industrial hemp growing formed the backbone with this wholly agricultural area of Spain. Towards the finish of the Franco era, with the invention of nylon and the mechanisation of agriculture all of the population was forced off the land to find work with the coast and major cities.
With the advent of the eco-age the curiosity about industrial hemp is being revived since it is really a major constituent of eco-bricks, an essential element of sustainable housing.
Hemp originates from the Anglo Saxon word’haemp’and is the most popular term for plants of the cannabis genus. Hemp usually describes the strains of the plant cultivated just for industrial use instead of cannabis which can be associated with pot and similar drugs.
Hemp includes a huge variety 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 many countries, including the European Union countries and Canada.
Cannabis sativa L. is the variety primarily grown for industrial purposes, it is really a fast growing plant and has been cultivated for many thousand of years being used to make rope, clothing, paper, hemp oil and medicines. Growing hemp improves the situation of the floor and reduces ambient contamination. It’s a robust plant that will require neither herbicides nor pesticides during its cultivation. red maeng da kratom
Hemp as a commercial material includes a ten thousand year history. The first recorded use of hemp was as a material fabric, within China as far back as 8000BC.C. Circa 4000B.C. hemp began to be used, again in China, to make 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 very first instances of hemp paper were found.
By the 6th century hemp had been used in Europe in a few amazing ways, in France a hemp reinforced bridge was built and it’s still being used today. The hemp fibre also found uses in sailmaking, caulking materials, fishing nets and lines. In later years hemp was used to make a number of foodstuffs including butter and beer. By the 15th century Renaissance painters were using hemp canvases.
Today industrial hemp is used to produce a staggering variety of products ranging from medicines, body maintenance systems, building and insulating materials, clothing, textiles, food, fuel, livestock food and bedding, plastics and paper.
In the building industry hemp bricks, due to their sustainability and excellent insulation properties, are now being used to make external and internal walls of ecological homes. Of this type of Spain the external walls of an eco house will consist of a eco-bricks, manufactured in Guadix with the proprietary name of Cannabric® ;.
Cannabric® derives its properties from industrial hemp fibres (cáñamo). The hemp bricks are composed of industrial hemp fibres, slaked lime and an assortment of innert mineral materials. The bricks combine the functions of a lot bearing wall that’s fire-resistant and does not require the addition of thermal or acoustic insulation.
The most important element of the eco-brick is industrial hemp that includes a suprisingly low thermal conductivity (0.048W/m²k) producing a brick with vastly superior insulation properties against both cold and heat. The mineral element of the bricks gives them their mechanical strength. Being a solid brick, with a top specific heat, it has the optimal thermal properties to protect against heat.
