About Hemp?
What is HEMP?
Hemp is indeed a God Plant. Not only is it one of the most sustainable, versatile ,planet-friendly plants around – it’s also one of the most nutritious and one of the best medicinal plants on our planet. Hemp which is believed to have originated from the Himalayas is one of the earliest domesticated plants known to man and has been grown for hundreds, and even thousands of years in many countries of the world.
HEMP - Infinite Possibilities
As mentioned above Hemp can be grown for extract-rich flowers, fibre (the “stalk” of the crop), seed, or as dual- purpose crop. The interior of the stalk has short woody fibres called hurds where as the outer portion has long fibers called bast fibres.
Using the above plant components, there are an estimated 25,000 products that can be derived from industrial hemp.
Hemp Fibre Products
There are three different fibre cells in hemp stems: primary phloem, secondary phloem and xylem. The primary phloem includes the outer cells that provide long fibers. The inner cells generated by the cambium provide secondary phloem short fibers, and inside the cambium is the wood (hurds), which provides short fibers. The longer the fibers, the more valuable they are. Thus Primary bast fibers are the most commercially valuable of the hemp fibers, followed by the secondary bast fibers and then the wood core fibers.
Textiles
With consumer preferences worldwide increasingly favoring natural products and production systems that are environmentally friendly, the market for textiles, fabrics and clothing that include fiber hemp has increased significantly.
Luxury designers have embraced hemp as a fabric. Giorgio Armani started a consortium to cultivate hemp in Italy. Other designer brands using hemp fabric include Versace, Ralph Lauren, Donna Karan, and Calvin Klein.
Alternative to Petroleum Products:
Bio-Plastic can be produced from either the fiber or oil of hemp. Because of the higher cost of producing hemp oil, the cellulose fibers are generally used. At this time, creating hemp-based plastic is both energy-intensive and expensive. There are advantages, however. Hemp plastic is durable – it is between 2.5 – 3.5 times stronger than petroleum based plastic. It is also 5 times stiffer, heat resistant, non-toxic and pesticide free. This makes it perfect for culinary use. It is also recyclable and biodegradable within 6 months.
Numerous auto and airplane manufacturers, including BMW, Volvo, Mercedes, Audi, Lotus, and Porsche, have used hemp-based plastics for their interiors for over a decade.
Due to its high biomass production, hemp shows promise as a bioenergy crop. Hemp can produce two types of biofuel. Bio-diesel is made from the oil of pressed seeds. Ethanol and methanol are made from fermented stalks. Mercedes Benz tested hemp bio-diesel on their cars and found that the mileage was comparable to fossil diesel fuel. Hemp biofuel could eventually become a viable sustainable alternative to fossil fuels.
Building Materials:
When mixed with limestone and water, a hemp composite material forms a type of concrete (Hempcrete) that can be used in building. Though it can’t be used as a load-bearing material by itself, it is significantly lighter than similar materials (1/9th the weight), and works very well as an insulation material that is airtight, yet breathable, flexible, and repels some vermin.
Hemp blocks can be formed into a building material similar to concrete blocks. They have a high thermal mass capacity that stores energy and releases it gradually. The blocks are resistant to insects, fungi, mold, mildew, fire, rodents, and termites.
Other products such as fiberboards and fiber-reinforced cement boards can also be made using Hemp.
Paper:
Hemp is a very efficient source of paper pulp. A single acre of hemp produces 4 times the amount of pulp that trees will over a 20-year growing cycle. Hemp also requires only approximately 4 months of growth before it is harvestable. Paper and pulp products such as hygiene products, banknotes, filters, art papers, tea bags etc can be made using hemp.
Other Products
Hemp Fibre is also used in horticultural planting materials; biodegradable mulch; pressed and molded fiber products, including those used in the automobile industry; insulation materials; animal bedding (made from the woody core of the plant called hurds);
Hemp seed or grain products
Hemp seed contains 20%–30% edible (fixed) oil; 25%–30% protein, which includes eight of the daily essential amino acids recommended for humans; 20%– 25% fiber; 20%–30% carbohydrates; and many essential nutrients and vitamins.
Humans have used hemp seed as food since ancient times. Grain or oilseed hemp products include hemp seed, seed flour, seed protein, seed powder, seed oil, and hemp meal. Nowadays, hemp grain is used in human health food because of the desirable ratio of omega-6 and omega-3 fatty acids in hemp oil.
Hemp seed oil is used in many cosmetics and as a substitute for other industrial oils. Hemp seed oil has a pleasant flavor and is used like olive oil as table oil and in salad dressing. Hemp seed oil should not be used for frying or baking; when heated at temperatures above 320°F (160°C), flavor declines, and it may produce toxic byproducts. Also, hemp seed and hemp seed oil do not have a long shelf life.
Hemp seed should be stored in dark containers and refrigerated to extend the shelf life and preserve the quality.
