Résumé
Although significant volumes of Alberta's trembling aspen resource are being used for pulp and for oriented strand board production, the species can be accurately referred to as "under-utilized" with respect to the production of solid wood products. It is well documented that the aspen's external indicators of quality correlate poorly with internal characteristics, making it particularly difficult to identify suitable sawlogs. This means that the greatest challenge around cutting aspen into solid wood products continues to be the identification of logs that are of suitable quality. This report details the development of an experimental log grade rule for use when evaluating aspen logs. The rule was developed to more accurately segregate those aspen logs that can be profitably cut to high-valued solid wood products from those more suitable for conversion to oriented strand board or pulp. In the first phase of the study, three samples each consisting of thirty logs that met the revised criteria were sawn, and lumber grade yields were calculated. Although the results were encouraging, it was recognized that larger samples needed to be evaluated. To this end, in the second phase, additional, larger samples were sawn, and grade yields again determined. Test results from the second samples largely replicate the first samples and show that logs that meet the revised criteria will more consistently yield high grades of lumber. The question of available volumes of the experimental log grade is also an important one. This report describes evaluations of aspen logs in inventory at three large manufacturing facilities in Alberta. It is inferred that between 1.5% and 3.5% of the log volume in sampled inventories meet the criteria for new log grade. Recommendations for follow up work include: detailed case studies that consider all of the economics of building and operating an aspen grade mill; a more comprehensive analysis of harvested volumes of aspen in order to more accurately estimate the available volumes of sawlogs meeting the standards for the new log grade rule; an analysis of the costs and benefits of using x-ray scanning technology to sort out aspen sawlogs from those more suitable for pulp or oriented strand board production; and an analyis of remanufacturing opportunities based on estimated yields of cuttings from the experimental log grade.

Résumé
Material handling has been identified as a key equipment and technology area that is a barrier to the success of Alberta value-added businesses. A project completed in March 2004 identified equipment and suppliers that could potentially resolve some of these issues. Unfortunately, many value-added companies have been reluctant to accept and implement these material handling solutions. This project builds on the 2004 findings by demonstrating the potential benefit of material handling improvements. This was accomplished by developing simulation modules for value-added manufacturing processes and specific material handling solutions, and then applying these modules to a lumber remanufacturer and a bedroom and occasional furniture manufacturer. Detailed equipment designs and costing for material handling equipment and systems were completed. These solutions were then evaluated for their effectiveness and return on investment while many opportunities for improvements to material handling were identified. The simulation of single production line improvements at the remanufacturer indicated increased efficiency and production output of all products by 6% to 31%. At the furniture manufacturer, efficiency and productivity increases were simulated to increase output by up to 115%. Plant wide analysis of material handling improvements at the remanufacturer was simulated to increase production from 7% to 42%, depending on the desired investment in resources and capital improvements. A proof of concept production planning optimization module was also developed. This module significantly enhances the benefit of the simulations by indicating which product options and product lines are most profitable. The results indicate that for one lumber raw material, only one of the production lines was generating significant revenue. The return on investment analysis shows that all of the recommended material handling improvements significantly increased saleable products. At the remanufacturer, an investment of $40,000 on one line could increase saleable product production by $275,000, a return on investment of 6.9:1. At the furniture manufacturer, an $85,000 investment was projected to increase saleable product output by $2 million, a return on investment of 24:1. Simulated plant wide improvements at the remanufacturer also showed significant improvements, with an investment of $75,000 potentially increasing the output of saleable products by $11.3 million. A technology mission to demonstrate advanced material handling solutions currently in use was planned, with trips to Europe and one to Quebec. The companies scheduled on the tour included high-speed producers of remanufactured products and solid wood components, building and furniture products, laminated products and finger-jointed components. Unfortunately, re-scheduling and extensive work with industry was insufficient to generate adequate participation to proceed with the missions.

Résumé
In recent years, significant attention has been paid to the engineering performance of wood structural systems, and a new generation of more reliable engineered wood components for building construction has evolved. The latest trend is towards advanced products that combine wood and synthetics. This increases performance and structural reliability of engineered wood products, and leads to new markets and expanded opportunities. It is anticipated that cost of fibre reinforcement decreases over time and advances developed on reinforcing techniques and methods of evaluation would provide wood producers with more options to better position their products in the marketplace. A new reinforcing technique has been developed and applied to manufacture a hybrid wood product for structural applications. The technique involves a layering analogy using layers of synthetic reinforcement sandwiched between layers of wood composite. The products manufactured in the laboratory used regular OSB laminations and alternating layers of E-glass fabrics and resin. Three- and four-ply billets were manufactured with various layouts and then tests were conducted to characterize mechanical properties of the hybrid products. Overall, the test specimens performed well relative to the controls. Shear failures were observed as a result of the limited performance of OSB in shear, and consequently the next tests will be conducted with plywood laminations instead of OSB. Selected issues related to code acceptance of structural FRP-reinforced wood products are discussed in the appendix. Future work is suggested to completely characterize and understand the properties and behaviour of the FRP-reinforced wood products, including fire performance, long term durability, maintenance and cost, in order to establish an environment in which to work comfortably with such materials. Overcoming these issues is vital for product acceptance in building codes.

Résumé
One of the major constraints to the growth and development of a value-added sector for trembling aspen in the solid wood industry concerns the inherent variability in quality of the resource. Much of the resource is simply not suitable for the extraction of lumber grades required to service markets for higher valued wood products, and those logs that are suitable for grade extraction are often difficult to identify. Recent market research details an interest in higher valued grades of aspen, particularly in Asia. On the basis of that market research it is worth investigating the predictive value of an alternative system of identifying aspen logs well suited for the production of high-grade lumber. This report details the conception and application of an experimental log grade rule for use when evaluating samples of aspen logs. The rule is intended specifically to separate high valued aspen sawlogs from those more suitable for conversion to oriented strand board or pulp. The log grading system presently used to evaluate most hardwood logs that are graded, one developed by the United States Forest Service, has been shown to do a poor job in estimating the value of aspen logs. The new log grade rule was based on the existing system, which was modified slightly to reflect some inherent characteristics of aspen. Three samples each consisting of thirty logs that met the revised criteria were evaluated. Test results reported here show that logs that meet the revised criteria will more consistently meet higher grades of lumber; however, more work must be done to confirm the predictive value of the new rule. In addition the issue of available volumes of logs meeting the revised criteria must be addressed.
