Hemp hurds

Raw hemp hurds

Hemp hurds, also known as shives or hemp wood, are an agricultural product made from hemp. Hurds consist of "the woody inner portion of the hemp stalk, broken into pieces and separated from the fiber in the processes of breaking and scutching" and "correspond to the shives in flax, but are coarser and usually softer in texture".[1]

Decortication

Decortication separates bast fiber from the hurd. The fine bast fiber is used to make textiles. Decortication is accomplished by manually crushing, a labor-intensive process, or by a hemp decorticator machine.[2][3]

Uses

Hurds can be used as stock in papermaking;[4][1] particleboard, hempcrete and other construction composites;[5] or bedding for animals,[4] particularly in horse stalls, which is the most common use (by weight) in Europe.[6]
