Once the areas major agricultural product, hemp is making a comeback in the Altiplano area of Granada, Spain. Before late nineteen sixties industrial hemp growing formed the backbone of the wholly agricultural area of Spain. Towards the conclusion of the Franco era, with the invention of nylon and the mechanisation of agriculture all of the population was forced off the land to locate work on the coast and major cities.
With the advent of the eco-age the fascination with industrial hemp will be revived since it is a major constituent of eco-bricks, an essential element of sustainable housing.
Hemp arises from the Anglo Saxon word’haemp’and is the favorite term for plants of the cannabis genus. Hemp usually describes the strains of the plant cultivated mainly for industrial use as opposed to cannabis that will be 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. may be the variety primarily grown for industrial purposes, it is a fast growing plant and has been cultivated for most thousand of years used to create rope, clothing, paper, hemp oil and medicines. Growing hemp improves the problem of the floor and reduces ambient contamination. It is a powerful plant that will require neither herbicides nor pesticides during its cultivation.
Hemp as a commercial material has a ten thousand year history. The initial recorded use 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 create 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 cases of hemp paper were found.
By the 6th century hemp had been used 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 create a number of foodstuffs including butter and beer. By the 15th century Renaissance painters were utilizing hemp canvases.
Today industrial hemp is used to make a staggering number of products including 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, 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 include 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 made up of industrial hemp fibres, slaked lime and an assortment of innert mineral materials. The bricks combine the functions of a load bearing wall that’s fire-resistant and doesn’t require the addition of thermal or acoustic insulation. detailed kratom review article
The most important element of the eco-brick is industrial hemp which has 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 truly a solid brick, with a high specific heat, it has the suitable thermal properties to protect against heat.
