Hemp absorbs CO2 via photosynthesis (PS) from the atmosphere to attain the C. PS removes the oxygen from CO2 and uses the C to build plant fiber.
Therefore 1 tonne of hemp fiber absorbs 1.6 tonnes of CO2 from the atmosphere to get the required amount of C needed for cell growth.
These figures, as good as they are, are not the whole story because they do not include the roots. Hemp has a massive root system that penetrates 1-2m, much deeper than any other commercial crop, and therefore hemp accesses nutrients not available to other crops and brings them up to the surface. Hemp is also one of the best bio-remediation plants and absorbs and removes toxins from the soil including radio-active waste. Hemp was used to remediate the soil after the Chernobyl nuclear disaster in Russia.
Since hemp stores such vast amounts of carbon, hemp building products are the best products for long term sequestration. Hemp panels will last for the duration of a building. Making both exterior and interior walls from hempcrete or hempcrete blocks can put the carbon away virtually forever. This is because hemp, lime and water, the raw materials for hempcrete, set up a chemical reaction that requires CO2 and this reaction is perpetually continuous. According to a Green Building Canada report, this results in approximately 110 kg Carbon sequestered per cubic meter of wall.
There is no other building material that can store this amount of carbon. The price, ease of use, clean and safe, non-toxic hempcrete is by far the best product for home and small scale construction. Hempcrete is also inflamable, mold resistant and breathes moisture therefore requiring no vapour barrier.
While hemp textiles, clothing, rope and paper, are the most noted hemp products there's an endless number of products either made from hemp, or that could be made from hemp bast and hurd fiber. Hemp products benefit people and the planet because they are safe and non-toxic. They can be used to replace many of the plastic, petrochemical and wood fiber products that are causing environmental pollution and climate crisis.
At HempNetMarket we believe that Hemp fiber products are part of the green sustainable solution. But it can only be successful if:
A sustainable future requires that most products in common use are bio-degradable and part of a green renewable circular economy. This goal is both attainable and completely necessary but requires a transition and restructuring of the manufacturing sector to using hemp fiber as a manufacturing feed stock.
Since hemp is an agricultural raw material, and it is not cost effective to ship hemp stalks, it requires primary production at or near where it grows. This adds important business opportunities in rural communities and will have a positive impact on the local economy.
Is hemp a fiber source to provide the feed stock for a Green Economy? Well it seems like the perfect solution staring us in the face, but it will take people demanding a safe, eco-friendly solution to move the program forward!
The exterior xylem and phloem of Hemp's make up the strong bast fiber. These cellulose fibers are extremely long and strong and great for making rope and twine. Hemp processors also use the bast fiber to make textiles, clothing, paper, diapers, hand bags, sneakers, fine fabrics, insulation, growth medium, bio-fiberglass, fiber board panels etc. This list goes on and on and new technologies are finding ever increasing use for this amazing natural fiber.
