The Forest Products Laboratory of the US Forest Service has opened
a US$1.7 million pilot plant for the production of cellulose nanocrystals (CNC)
from wood by-products materials such as wood chips and sawdust. Prepared
properly, CNCs are stronger and stiffer than Kevlar or carbon fibers, so that
putting CNC into composite materials results in high strength, low weight
products. In addition, the cost of CNCs is less than ten percent of the cost of
Kevlar fiber or carbon fiber.
