In addition, the thermo-mechanical compaction enables new, non-cutting manufacturing processes for technical profiles made of wood.<\/p><p>If lignin and hemicellulose are first removed from the wood by chemical-thermal processes, volume reductions by a factor of 5 are possible with an analogous increase in density. After pre-treatment and compression, a twelfe-fold increase in strength could be demonstrated.<\/p><p><strong>Technical solution<\/strong><br \/>The aim of the Woodtrusion project was to process local thin wood into high-quality construction wood in the form of tubes. In extensive material tests, optimal process parameters for compaction degree, temperature and moisture were determined using spruce wood.
