Let’s rehabilitate industrial hemp!
published: 02/03/20, 15:02
Hemp is a miraculous plant that was demonized in the USA in the 30s by lobbies in the cotton, paper and chemical industries (Dupont, again ...) who instrumentalize the virtue leagues (intentionally amalgamating recreational and industrial cannabis) giving birth to the Marihuana Tax Act which will introduce the taxation of all players in the hemp sector.
Nylon will then impose itself (Dupont, always) until the army considers this material as unsuitable for its needs (it creates allergies, promotes skin diseases, is putrescible and not as solid as expected).
The United States Department of Agriculture then sponsored a film "Hemp for victory" released in 1942 which encouraged farmers to plant textile hemp to participate in the war effort, a heavy consumer of fabric and ropes.
Remember that hemp is a rot-proof fiber, resistant to insects and UV rays, 8 times more resistant than cotton to traction, with which we can make fabrics as fine as silk, veils, ropes, paper. Its uses are almost unlimited.
The improvement will be short-lived and hemp will be banned after the war.
This for the fiber.
But let's review the qualities of this plant:
-It produces edible seeds (without psychotropic effect), with high nutritional value as well as an oil containing omega 3 and omega 6.
-After pressing them, there remains a very rich protein flour.
-It aerates the soil without depleting it.
-It chelates heavy metals.
-It can be used as green manure and does not need pesticides because it is naturally very resistant and few biological enemies.
-It can be used as an adjuvant in resin which can advantageously replace fiberglass.
-It was used in Chernobyl to neutralize cesium 137, strontium 90, and plutonium.
-It has an unbeatable fiber yield (liber): from 900 to 2700 kg per hectare, more than any other fiber plant.
-It only needs a little water and could replace cotton advantageously with all the advantages expected from a crop in an increasingly polluted future.
-It lends itself to any form of use: after removing the liber, the pulp of the plant can be transformed into a wide range of materials (plaster, stucco, fiberboard, concrete blocks and thermal insulation).
-It can give a bioplastic for 3D printing. Ford had in 1941 released a hemp bioplastic automobile weighing 500 kilos less than its equivalent steel model. Project abandoned of course!
The list is not exhaustive.
This is only industrial hemp. Medicinal hemp also holds great promise, as applications and properties for the various components of this plant are constantly being found. I won't talk about it here.
