Non Technical Summary
The US Forest Service faces high costs of forest management to remove small diameter trees that increase fire risk in overgrown forests, invasive tree species that are crowding out native trees, and insect killed, and diseased trees. The US paper industry is the largest user and highest value user of small diameter trees and other waste wood and this value mitigates the cost of forest management. In addition to demonstrating the suitability of suppressed growth trees, decayed trees and non-native species for paper applications, this problem area includes high value by-products and development of environmentally preferable pulping and bleaching processes including waste paper recycle and deinking. Specific tasks of interest including wood chemical characterization methods using Raman spectroscopy and nuclear magnetic resonance spectroscopy that can help understand changes in the major chemical components of wood (cellulose, hemicellulose and lignin) during biorefinery pretreatmenst and the chemical methods for isolating cellulose nano-materials. A second task area is to use modern instrumental methods to identify very low-concentration compounds produced by the trees with the thought that many of these complex molecules are biologically active and can serve as precursors for drug development and other high value chemical needs.

Objectives Summary
Improve the understanding of fundamental wood chemistry and wood chemicals with objectives of improving the processes for producing wood fiber for paper and particleboard, and enhancing the value of both traditional and novel tree-sourced chemicals. The wood fiber component of the objectives incudes research support on critical problems in the traditional paper industry: pulping, bleaching and recycle. The fundamental wood chemistry of this problem area supports the process and product development work of problem area 1B on biorefinery, and problem area 2B on cellulose nano-materials.
