A Brief History of Industrial Hemp
Humans have been using hemp for thousands of years. The earliest recorded use of hemp dates back to 8000 BCE in Asia where it was used to make cloth, rope, and pottery.
For centuries, hemp was an important crop worldwide thanks to its many applications. It was grown extensively across Asia, Europe, Africa, and the Americas. In fact, several Founding Fathers of the United States grew hemp including George Washington and Thomas Jefferson.
Hemp was so important that in 1619, the Virginia Assembly passed a law requiring every farmer to grow hemp. For over 200 years, hemp was considered a legal tender that could even be used to pay taxes.
However, in the 1930s, attitudes towards cannabis began to change. Marijuana was criminalized which also resulted in a ban on hemp cultivation. This ban lasted over 50 years until industrial hemp production was once again legalized in the 2014 Farm Bill.
Today, hemp is seeing a resurgence as we rediscover its many benefits. The global industrial hemp market is expected to grow into a $15 billion industry by 2027.
What Makes Industrial Hemp Different From Marijuana?
Industrial hemp and marijuana both come from Cannabis sativa but are distinct varieties. On a genetic level, industrial hemp contains lower levels of THC, the psychoactive compound responsible for marijuana’s high.
By legal definition, industrial hemp cannot contain more than 0.3% THC content. Marijuana, on the other hand, contains anywhere from 5-35% THC.
At these low levels, it is physically impossible to get high from consuming industrial hemp. It would be like trying to get drunk from a non-alcoholic beer.
In appearance, industrial hemp and marijuana look quite different. Hemp plants are skinny and tall while marijuana plants tend to be short and bushy.
So in summary:
- Hemp has less than 0.3% THC while marijuana can have up to 35% THC
- Hemp is tall and skinny; marijuana is short and bushy
- Hemp will not make you high but marijuana will
This makes hemp an incredibly versatile crop without the psychoactive effects of marijuana.
How is Industrial Hemp Grown and Processed?
Industrial hemp can be grown both outdoors and indoors. However, it thrives best in warmer climates with temperate weather conditions. Ideal growing locations include China, Europe, and Canada.
Hemp is ready for harvest in just 3-4 months making it a rapidly renewable resource compared to trees which can take decades to mature. The plants reach heights of 2-4 meters tall with long, fibrous stalks.
After harvesting, the hemp stalks go through a process called decorticating which separates the tough outer fibers from the soft inner core.
The two main components extracted are:
- Bast fibers - the long, tough outer fibers located along the length of the hemp stalk. They are used to create textiles and ropes.
- Hurds - the soft, inner fibers found in the core of the hemp stalk. They are used to make paper, absorbents, and building materials.
In addition, hemp seeds and flowers are also harvested from the plants. They are processed into food products, oils, and extracts including the popular cannabidiol (CBD) supplement.
Now that you understand the basics of how hemp is grown and processed, let’s look at why it is such an amazing crop.
4 Key Benefits of Industrial Hemp
There are many good reasons why hemp is one of the most versatile crops on the planet:
Hemp has a very positive environmental footprint. It enriches soil, requires less water than cotton, and eliminates the need for pesticides and herbicides.
Hemp also sequesters large amounts of carbon from the atmosphere. One acre of hemp can absorb 4 times more CO2 than an acre of trees.
With its rapid growth cycle, hemp is considered a carbon-negative raw material. This means it actually reduces carbon emissions.
Fibers derived from industrial hemp are incredibly strong and durable.
For example, hemp fiber has been used to reinforce concrete. The blend of hemp and limestone forms a natural composite material called hempcrete which is highly resistant to cracking.
Hemp textiles are also long-lasting. In fact, the first pairs of Levi’s jeans were made from hemp sailcloth!
As mentioned earlier, hemp grows rapidly in just 3-4 months. This makes hemp far more renewable than slow-growing trees used to manufacture paper, clothing, and construction materials.
Hemp stalks continuously regenerate new shoots after being harvested so they can be grown densely as a renewable crop year after year.
Because the entire hemp plant can be utilized, every part of it adds value. Hemp provides food, clothing, housing material, paper, cosmetics, and even energy.
It’s no wonder hemp has been called a “cash crop” due to its versatility and profit potential for farmers. Hemp delivers significant opportunities across numerous sectors and industries.
Now that you know some of hemp’s biggest benefits, let’s go over all the different ways it can be used.
The Many Uses of Industrial Hemp
With over 25,000 known applications, hemp truly is a miracle crop. Here are some of the top ways hemp is being utilized today:
Hemp Fibers for Textiles and Rope
For centuries, hemp fibers have been used to manufacture clothing, bags, shoes, carpet, home furnishings, and industrial rope.
Hemp fiber is exceptionally durable and comfortable. It also gets softer with use which makes it ideal for fabrics.
Hemp clothing provides UV protection and antimicrobial properties to inhibit odor-causing bacteria. Fiber production uses the long bast fibers extracted from the hemp stalks.
Fun fact: The word canvas comes from the Latin word for hemp, cannabis!
Hemp Paper Production
Before 1883, over 75% of the world’s paper was made from hemp fiber including bank notes, archival papers, maps, bibles, and newspapers. Hemp paper was crucial for written communication.
Hemp paper fell out of favor once wood pulp paper was introduced which was cheaper to produce using new industrial methods.
However, wood pulp paper requires large amounts of chemicals for processing and results in more pollution and deforestation.
Hemp paper made from the inner hurds of the hemp stalk is a sustainable alternative. Hemp paper is naturally whiter, stronger, and lasts longer than wood paper. Each acre of hemp can produce up to 4x more paper than an acre of trees.
Hemp Building Materials
The woody inner fibers of hemp stalks provide excellent properties for construction.
When mixed with lime to create hempcrete, this lightweight material can be cast into blocks, bricks, and panels for building homes and structures.
Hempcrete is environmentally friendly, fire-resistant, mold-resistant, and provides excellent insulation. Using hempcrete could significantly reduce the building industry’s carbon footprint.
Hemp Biofuels and Plastics
Hemp seeds and stalks can also be converted into clean-burning biofuels such as ethanol, methanol, biodiesel, and methane.
Hemp biomass can also be processed into biodegradable hemp plastics to replace petroleum-based polymers. Imagine replacing plastic bottles, packaging, and bags with plant-based hemp plastics that biodegrade instead of polluting the planet.
Hemp Foods and Nutraceuticals
Hemp seeds are an extremely nutritious superfood. They are rich in protein, fiber, essential fatty acids, magnesium, iron, and zinc.
Hemp seeds can be consumed raw, ground into hemp flour, or pressed into hemp oil which has culinary and topical uses.
Hemp extracts are also abundant in phytochemicals, terpenes, and cannabidiol (CBD) which possess therapeutic benefits. CBD from industrial hemp is widely used for health and wellness.
Hemp for Pet and Animal Care
Many pet owners have discovered the benefits of hemp. There are hemp pet supplements, treats, bedding, kitty litter, bird seed, and even hemp clothing and toys.
Hemp bedding provides superior absorption for animal litter. Hemp pet food improves skin, fur, mobility, and digestive health in cats and dogs. Hemp extracts like CBD can reduce anxiety in pets during stressful events like thunderstorms and travel.
As you can see, industrial hemp has so many valuable uses that benefit people, animals, and the planet. But there is still one challenge limiting hemp from reaching its full potential.
The Main Challenge Facing the Hemp Industry
While hemp was legalized in the 2018 Farm Bill, there is still some confusion around cannabis laws which inhibits public acceptance and investment into hemp.
The main challenge facing industrial hemp is resolving policy conflicts between state and federal laws regarding hemp and marijuana. While hemp is now legal federally, there are still a complex patchwork of laws around cannabis at the state level.
For example, in some states, hemp farmers struggle to open bank accounts and get insured for growing state-approved hemp due to it being mistaken for marijuana.
Clearer policies need to be implemented so that hemp farmers and businesses can operate smoothly across state lines without legal repercussions. This will provide the clarity and security needed for the hemp industry to really take off and achieve its potential.
The good news is hemp has bipartisan support. The public is also becoming aware of the benefits of hemp and how it differs from marijuana. So the outlook is bright for advancing hemp legislation.
The Future Looks Bright for Industrial Hemp
With greater education and sensible policies, industrial hemp could significantly transform society.
Hemp can power our future in sustainable ways by providing food, textiles, materials, energy, and medicine with minimal environmental impact. It can help solve problems around climate change, pollution, and depleting resources.
There are still misconceptions around hemp which need to be cleared up. But the truth is hemp has no psychoactive effects and enormous benefits.
Businesses will continue finding innovative new ways to utilize this ancient plant and optimize it with modern technology. Hemp brings together the best of the past and possibilities of the future.
