When the areas major agricultural product, hemp is building a comeback in the Altiplano section of Granada, Spain. Before the late nineteen sixties industrial hemp growing formed the backbone with this wholly agricultural section of Spain. Towards the end of the Franco era, with the invention of nylon and the mechanisation of agriculture a lot 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 curiosity about industrial hemp has been revived since it is a major constituent of eco-bricks, an important component of sustainable housing.
Hemp comes from the Anglo Saxon word’haemp’and is the favorite term for plants of the cannabis genus. Hemp usually refers to the strains of the plant cultivated just for industrial use instead of cannabis which is associated with pot and similar drugs. best kratom for pain
Hemp includes a huge number of uses but continues to be overshadowed by the cannabis connotation of illegal drugs, with which it is often confused. However hemp can legally be grown, under licence, in lots of countries, including the European Union countries and Canada.
Cannabis sativa L. is the variety primarily grown for industrial purposes, it is a fast growing plant and has been cultivated for most thousand of years getting used to produce rope, clothing, paper, hemp oil and medicines. Growing hemp improves the problem of the floor and reduces ambient contamination. It’s a strong plant that requires neither herbicides nor pesticides during its cultivation.
Hemp as an industrial material includes a ten thousand year history. The initial recorded usage of hemp was as a cloth fabric, present in China as far back as 8000BC.C. Circa 4000B.C. hemp began to be 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 first cases of hemp paper were found.
By the 6th century hemp had been utilized in Europe in some amazing ways, in France a hemp reinforced bridge was built and it is 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 is employed to produce a staggering number 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, for their sustainability and excellent insulation properties, are now being used to make external and internal walls of ecological homes. In this area of Spain the external walls of an eco house will consist of 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 composed of industrial hemp fibres, slaked lime and a combination 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 main component of the eco-brick is industrial hemp that includes a suprisingly low thermal conductivity (0.048W/m²k) producing a stone with vastly superior insulation properties against both cold and heat. The mineral component of the bricks gives them their mechanical strength. Being fully a solid brick, with a higher specific heat, it’s the suitable thermal properties to protect against heat.
