Abstract [en]

If monocotyledons are to be used in particleboards, their external surfaces should be modified to increase their wettability by conventional adhesives such as melamine-urea-formaldehyde (MUF). The modification should affect the wax layer of the external surface of monocotyledons. According to the literature, modification by enzymes leads to increased wettability by water-based adhesives. The purpose of this study is to evaluate the integration of surface treatment by enzymes into particleboard production in a way that leads to a value added output. During the pre-treatment process, it can be expected that residues such as fines and organic acids will accumulate. These residues can be used for methane production, and this should increase the efficiency of the process. Once established, the methane production can be extended to include other residues from the wood process, leading to an increased energy production. A residue of this methane process is lignin which is nowadays generally used as a fertilizer and energy source, but research is also focusing on the use of lignin as an adhesive or additive. A SWOT analysis of the literature shows the advantages and disadvantages of integrating a pre-treatment of monocotyledons into the particleboard production process. In addition to a mixture of light-weight raw material for particleboard production, energy and maybe additives for adhesives, this concept also supports the production of panels with a greater range of densities by using different proportions of the different raw materials
