INDUSTRIAL HEMP
Hemp is often described as one of the first cultivated plants in history. In fact, the oldest cannabis relics are dated to 8000 BC, proving that humans have cultivated, processed and used the plant for millennia.
Hemp is an industrial plant that belongs to the same family as the cannabis plants that are used to produce marijuana. It is cultivated on a commercial scale in many countries around the world, such as Australia, the United States, the United Kingdom, Canada, Vietnam or France, among others.
Although hemp and cannabis belong to the same plant species, they are very different, not only in their appearance, but also in their chemotypes (chemical compositions). Hemp, for example, has much lower concentrations of THC, while marijuana tends to be rich in this cannabinoid.
Being produced for completely different reasons, hemp and cannabis often require different growing conditions. Cannabis used for the production of marijuana, for example, has been selectively bred for
generations to obtain female plants that produce large quantities of cannabis flowers.
While hemp plants can be female, those grown for industrial purposes are generally male and do not produce flowers. These plants are also bred selectively and grown in conditions that enhance their height and the development of thick, long stems.
USES OF INDUSTRIAL HEMP
Hemp is one of these crops, as it is used for more than 25,000 biodegradable and easily obtainable products, biologically and environmentally correct: from the food industry, both for humans and animals, to the automotive, through cosmetics or clothing. It is also used as a fuel or building material and even any material made from plastics or wood can be successfully reproduced from hemp plants.
In addition, as it is a material with great medicinal applications, biodegradable and recyclable, there are many who are thinking of hemp as a perfect option to invest. One can talk about the usefulness of hemp, among other uses, for:
CBD PRODUCTS
One of the uses of hemp that people have become familiar with lately is the production of cannabidiol. And it's true, CBD consumers have a lot to thank hemp for. Unlike the marijuana plants we are more used to, hemp plants have negligible THC content and are rich in CBD. Since many CBD users are not interested in any of the psychoactive effects associated with THC, hemp has become the crop of choice for farmers making CBD products. From there, it is treated in a similar way to normal cannabis to create butter, edibles, or oils, among other things.
CLOTHING / FIBER
Hemp was one of the first plants used to make fibers, and some samples of Chinese hemp fiber date back to 8000 BC. Today, hemp is still used to make clothing, and lately it's seeing a resurgence.
Although hemp clothing is often associated with "hippy fashion" (such as hemp vests and baggy pants), some new designers are using this fabric to create modern items that challenge that stigma.
PAPER
Hemp fiber can be used to make paper in much the same way as wood fiber. In fact, until the middle of the 19th century, hemp was the main material used to produce paper around the world, at which point wood began to take over little by little.
Hemp is actually better suited for paper production than wood, as it contains much more cellulose. Cellulose is what gives plants their structure, and the more cellulose a plant contains, the more suitable it will be for producing paper, as fewer chemicals will be required to extract it.
FOOD
Hemp seeds have received much praise for their great nutritional value and because they contain high levels of protein, calcium, iron, and essential fatty acids, among other things. As a result, they have become very popular as a type of superfood and are often sold as a dietary supplement.
However, hemp can also be used to make oil and milk, and is often used as an additive in alcoholic beverages such as beer and wine. Furthermore, hemp seeds can be used as a nutritious alternative to animal feed.
PLASTIC
Hemp can be used to make a wide variety of plastics. In fact, in the 1940s, Ford produced a prototype car made of hemp and soy plastic. Unfortunately, this vehicle was never marketed, but there is a very famous photograph of Henry Ford with an ax proving its durability.
Today, a mixture of fiberglass, hemp fiber, kenaf, and flax is used to make composite panels for automobiles. Hemp plastics are also used to make shower curtains, CD and DVD cases, and much more.
fuel
As we have mentioned above, hemp can be used to make oil. And like other vegetable oils, it can be processed to produce biodiesel. The plant can also be fermented to create ethanol or methanol. However, the production of hemp fuels is very small, because commercial biodiesel and biogas are often made from cheap materials.
filters
Hemp can be used mixed with other fibers to make all kinds of filters, such as tea bags, coffee filters or oil filters, among others. Hemp fiber is very resistant, especially in humid conditions, making it an ideal material for the production of
any type of filter for liquids.
In fact, tea bags are often made from a combination of wood fiber and hemp, as well as plastic polymers. There are also pure hemp filters and bags, which are very easy to wash and can be reused.
ISOLATION
Hemp can be used to make a wide variety of building materials, especially those intended for insulation. In fact, hemp is already used as an insulator in the Netherlands and Ireland, among other countries around the world.
It can also be used to make products such as chipboard and pressboard, and even as a stronger, lighter and more environmentally friendly alternative to concrete, known as' hempcrete.
BEAUTY PRODUCTS
The beauty industry already has a wide variety of creams, lotions, balms and gels made with hemp. The plant is known to contain many extremely beneficial compounds for skin health, such as vitamins or essential acids. for Hemp-based CBD creams are also used in the treatment of some skin conditions, such as eczema, arthritis, and others. types of rashes, ulcers, or irritations.
WATER / SOIL PURIFICATION
Hemp is sometimes referred to as a "mop crop" as it can be used to purify water or soil. For example, hemp plants are sometimes used to remove impurities from sewage or excess phosphorus from poultry waste. This can help some farmers avoid the use of herbicides, which is essential for those seeking organic farming certification. for One of the most interesting uses for hemp was in the 1990s, when it was planted in Chernobyl, Ukraine, where it proved to have enormous potential for cleaning pollution from the land. As is evident from the examples above, hemp goes beyond being versatile. We do not know how exactly the hemp industry, but the resurgence in hemp production indicates a return to its widespread use in many commercial markets.
