The design and management of tree plantations based on fast-growing hardwoods species focus on realization of various products and related applications. An illustrative case is the European poplar cultivation. At the end of the rotation (10-25 years), the tree can be divided into commercial assortments types that allow an integral use of the biomass produced. In this sense, the lower portion of the stem, up to a height of 5-8 meters, is intended for peeling and the production of plywood and LVL (Laminated Veneer Lumber). The part of the tree containing defects not permissible for these products, can still be used for processing in sawn timber or derived products like glulam and CLT (Cross-Laminated Timber) and finally also OSB (Oriented Strand Boards) is an option. All these products are named Engineered Wood Products (EWP) that can be used to increase the potential resources for Building with Wood including enhancing the basic properties by innovative treatments.
