Non Technical Summary
Wood pulping is the largest commercial use of otherwise unmerchantable lumber. It can readily accept small diameter and crooked trees and species that do not perform well in dimension lumber applications. The pulp and paper industry is also a well established biorefinery business, generating paper, chemical products like turpentine, rosin and soap, and energy from the black liquor byproduct and from waste wood. There is considerable interest within the industry to evaluate wood pretreatment conditions that will allow them to extract sugars and produce ethanol as well as paper and these other chemical products.

Objectives Summary
Evaluate pulping and paper applications for underutilized wood resources such as suppressed growth and small diameter wood and invasive tree species. Evaluate pulping and paper applications on wood that has been treated by prehydrolysis to obtain sugars for fermentation to ethanol and other higher value chemical products.

Approach Summary
Underutilized wood resources are evaluated for performance in kraft or thermomechanical pulping applications. Pulp is tested for quality and paper grade requirements. Typically conference presentations or publication in trade journals is all that is needed to increase pulp mill interest in underutilized wood resources. Use of prehydrolyzed wood will require changing the pulping conditions to preserve strength and yield. This can be accomplished by lowering the cooking temperature, controlling alkali charge, and use of additives like polysulfide, borohydride, or anthraquinone.
