Study of Eucalyptus processing for utilization as solid wood

The general aim of the project was to improve the technological valorisation of blue gum (Eucalyptus globulus Labill). The first phase of the study concentrated on the assessment of the wood quality from nondestructive measurements of standing trees. The specific topics were growth stress, harvesting techniques and physical and mechanical properties. In the second phase, the first transformation processes were studied. Results and recommendations contribute to the optimisation of sawing, peeling and drying methods. The gluing studies proved that it is possible to produce plywood panels in industrial scale presenting good quality for exterior use (according to EN 314-2). The moist gluing system (BORDEN) produced satisfactory results. Specific conditions to produce glulam beams were determined and knowledge about the natural durability of eucalyptus obtained. Characteristic values of solid wood were derived and, finally, glulam, windows, doors, laminated profiles and flooring and ceiling elements were produced by industry.
