Core, also known as shive, shiv, or hurd, is the inner part of a bast fiber plant, such as hemp or kenaf, that is left once the fibers are stripped. This wood-like material is broken into pieces during processing and separated from the fibers of the plant. These hurds are highly absorbent, rich in cellulose and have great thermal and acoustical properties. They have strong applications for creating sustainability in both commercial and construction industries.
