Because it takes a significantly larger amount
of hemp stalks to produce hemp oil, there is an increased risk of contamination of toxins contained within the plant.
The college will continue to study pest and nutrient management, and identify new opportunities for the use of
hemp stalks as animal bedding and the potential for the plant to be used for soil remediation.
«Canadian hemp currently can be used only for seed and fiber... (because only trace amounts of cannabidiol are found
in hemp stalks and seeds, much of the value of Canada's hemp crop currently goes in the trash).
Hempcrete is a mixture of the inner core of the
industrial hemp stalk (known as the hurd or core), lime and water.
Studies
on Hemp Stalk and Shive Pulping by V.S. Krotov, Ukrainian Pulp and Paper Research Institute, Kiev, Ukraine, Russia.
He held up a tuft of fibers next to a bale of
raw hemp stalks and told how the material could be turned into linenlike cloth.
The inner fibers of
the hemp stalk, called hurds, are known for their low density and high absorbency, which means they can be mixed with plaster or lime to make cheap and efficient building materials.
Bast is the outer fiber of
the hemp stalk, and just about anything can be made from it — clothing, rope, rugs or plastic.
The extraction process involves using a solvent to extract the oil from
the hemp stalk.
Hempcrete, which sounds rather like a made up hippie word instead of an alternative building material, is a fascinating green construction option that uses the hurds, or inner woody core of
the hemp stalk (as opposed to the bast fibers, which are used for textiles and cordage), in a mineral matrix, to form a non-toxic, carbon - negative, and energy - efficient material.
«Although Cannabis flavored candies likely will not cause a psychoactive effect and contain insignificant trace amounts of THC, they will be considered illegal insofar as they include fragrance or flavorings derived from the non-exempt trace resin of
hemp stalks or other parts of the Cannabis plant.»
The Hemp Stalk The stalk of the hemp plant contains two types of fiber — the outer bast fiber which can be processed into long strands, and the inner woody core, or hurds, which are typically processed into material resembling wood chips.
For example, starch from corn grown in the midwest has traditionally been the source of some of the ethanol used as a fuel additive in the U.S.. Another option for the conversion of cellulosic biomass, such as
hemp stalks, to ethanol is their hydrolysis to sugar, followed by fermentation and removal of the produced ethanol by distillation.
Baling equipment condenses the bulk of
hemp stalks, reducing transportation costs from field to the conversion plant.
