HEMP, or industrial hemp, is a botanical class of Cannabis sativa cultivars that are cultivated specifically for industrial or medicinal use. It can be used to manufacture a wide range of products, such as paper, ropes, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food and animal feed.
Hemp
is one of the fastest growing plants on Earth and was one of the first plants to be spun into usable fiber 50,000 years ago. It has properties that allow resistance to mold and its porous material makes the building materials that compose it breathable.Manila is sometimes referred to as Manila hemp, but it is not related to hemp; it is abaca, a species of banana. In 1937, the Marijuana Tax Act of 1937 was passed in the United States, which imposed a tax on anyone who marketed cannabis, hemp, or marijuana. Hemp from a variety of cereals is predominantly used in the food and nutrition industry due to its high content of proteins, fiber and fatty acids. It can also be used as a mop to remove impurities from wastewater, such as wastewater effluents, excess phosphorus from chicken waste or other unwanted substances or chemicals.
For centuries, items ranging from ropes to fabrics and industrial materials were made from hemp fiber. Hemp paper are varieties of paper that are composed exclusively or largely of pulp obtained from industrial hemp fibers. In the Australian states of Tasmania, Victoria, Queensland, Western Australia, New South Wales and South Australia, state governments have issued licenses to grow hemp for industrial use. Several arthropods can damage or damage hemp plants but the most serious species are associated with the Insecta class.
When oxidized (often erroneously referred to as dried), hemp oil from seeds solidifies and can be used in the manufacture of oil-based paints, in creams as a moisturizing agent for cooking and in plastics. The porous materiality of hemp insulation allows the penetration of air and moisture with an apparent density of up to 20% without losing any thermal properties. HEMP plants can be vulnerable to a variety of pathogens such as bacteria, fungi, nematodes, viruses and other diverse pathogens. Today hemp producers can legally grow industrial hemp in most states which also allows them to focus on specialized reproduction and genetics programs.
George Washington also imported the hemp plant from India from Asia which was used as fiber and by some producers for the production of intoxicating resin. In the early 1990s industrial hemp agriculture in North America began with the University of Manitoba's Hemp Awareness Committee. In the United States the cultivation of hemp is legally prohibited but during World War II farmers were encouraged to grow hemp as a string to replace Manila hemp that was previously obtained in Japanese-controlled areas.
