Core Fiber Core fiber is derived from the sturdy, wood-like hollow stalk of the hemp plant. Sometimes referred to as "hurds", it is up to twice as absorbent as wood shavings, making it an excellent animal bedding and garden mulch. It can be easily blended with lime to create a strong yet lightweight concrete or plaster. Its high cellulose content means it can be applied to the manufacturing of plastics. Like primary fiber, it is biodegradable and possesses antimildew and antimicrobial properties. U.S. Legal Definitions
