Abstract
The current project was initiated to address the utilization of the lignin component obtained during the bioconversion of aspenwood wastes. This utilization is necessary for the economic viability of the whole conversion process. The lignin obtained from steam pretreatment has been suggested to be of low molecular weight, reactive, and offer great potential as a raw material for utilization. This is in contrast to the lignins from traditional pulping operations. However previous to this work, characterizati- on of lignin separated after steam pretreatment of aspenwood under varying conditions (with and without acidic catalysts), has not been undertaken to substantiate these widely held beliefs. Neither has anyone identified the production of the type of lignin most suitable for various applications. A prerequisite for utilization of this material, therefore, has been to undertake this necessary characterization. A major emphasis of the work during this first year has been placed on the establishment of the analytical capability required to achieve the above goals. Following discussions with other researchers, such as Glasser and Lewis (Virginia Tech.), Chum (SERI), etc. we are confident the analytical methodology we have in place for lignin characterization and the assessment of planned modification reactions is as good as any other laboratory in the world.

Abstract
The relationship of press closing time, strength properties and density profile of thick waferboard panels to mat moisture content was demonstrated in this study. Lower mat moisture contents were found to increase press clothing time but permit faster binder curing. When the distribution of mat moisture was higher in the face layers, shorter press times were achievable and a significant densification of the panel was observed.

Abstract
Various Kraft lignin binder formulations with phenolic resins were developed and tested in terms of application, curing requirements and product performance. The two most promising glues were selected and this report presents their evaluation as binder for laminated lumber. For the first time, a rapid method of curing lignin adhesives in laminated lumber was developed using the residual heat from pre-heated wood. The study has confirmed that rapid lamination of lumber using low cost lignin binder is possible. Further study for rapid methods of pre-heating the laminae and application of the binder is required. The development of a faster curing low cost binder would be the best improvement to the process.
