Hemp in construction has become a sustainable solution, due to its properties, resistance, flexibility, and its thermal and insulating power.
Hemp is also used as a replacement for wood in the production of insulating panels, planks and as the main component in compact bricks used in the construction of roofs, interior and exterior walls, among others. One of the advantages is that homes built from hemp sheets or bricks are more resistant, insulated and waterproof.
The cultivation of hemp is beneficial for agriculture because from an ecological and environmental point of view, it does not need herbicides or pesticides, it also has the quality of retaining enviro Caseno Email List nmental pollution because during its growth it purifies the air and reduces CO emissions.
Likewise, it improves the quality of the soil after cultivation, in fact, it returns approximately % of the mineral extraction it carries out to the land.
The countries with the highest hemp production are China (% of world production), Russia, Canada and France.
The average annual harvest of hemp fiber is around ,, qm.
Hemp is that magical crop that does everything, according to studies
It has become almost a cliché to discuss the benefits of hemp, the supposed wonder plant with almost infinite uses, from woven fibers to edible seeds and bioplastics. “Of course, hemp is that magic crop that does everything,” says Nicholas Carter, an environmental researcher who, along with Tushar Mehta, a Toronto-based doctor, runs the website Plant Based Data.
Your job is to read scientific articles and studies and summarize the most important work supporting plants as a food source and other important uses. Given the hype, Carter wondered how much power hemp really had. "I wanted to look at the research that's out there on this, to see what's really real, what's really supported by studies," he says.
Magic? Not quite. But Carter walked away from his attempt to discredit a hemp fan. And he discovered that one of the many most promising uses is its application as a building material known as hempcrete.
Hempcrete: uses of hemp in construction
Like the concrete of the same name, hemp is a material mixed with a binder that hardens it into a solid in the form of blocks and panels. Made from the dried woody core of hemp stalks and a lime-based binder, hemp can be molded like concrete.

But unlike concrete and its cement binder, which accounts for about % of man-made carbon dioxide emissions annually, hempcrete actually sequesters CO . According to a recent study, hempcrete can sequester kilograms of CO per cubic meter, roughly equivalent to the annual carbon emissions of three refrigerators.
“As we grow it and make hempcrete, it is absorbing CO all the time and encapsulating the CO in the structure,” says Eric McKee, founder of the US Hemp Building Association.
SR Karade, senior principal scientist at the Central Building Research Institute in Roorkee, India, outside New Delhi, has been studying hemp and wrote in a recent article for the Journal of Cleaner Production about how hemp performs as a building material in terms of insulation: durability, structural resistance and acoustic control, among other criteria.
Overall, Karade found, hempcrete meets current standards for most construction applications and in many cases, outperforms materials currently used, particularly for insulation.
