Paper is the main ingredient of LWCC and so its properties depend on paper’s microstructure. Woodfragments are thermo metrically or mechanically treated to dissolve the lignin binder and to free thecellulose fibers. Paper is then made by pressing the pulp to remove excess water. Paper is an anisotropicmaterial and the quality and strength of its fibers differs depending on several factors. They are, the typeof wood, the percentage of recycled paper, the amount of water in the pulp, the way of pulping (chemicalor mechanical) and the speed of drying. Today half of the paper fiber utilized in current production comesfrom recovered fibers. Yet recovered fibers are inherently less strong and moving the pulp meansorienting the fibres.
