Abstract

This research proposes a wall panel component molded from a wood of bracatinga (Mimosa Scabrella) and a lignin-phenol-formaldehyde adhesive. The development of a product with a simple and ecological construction technology was adopted as the approach, using low-cost wood particles. A composite made of bracatinga wood particles and alternative residual lignin (lignin-phenol-formaldehyde) adhesive was developed and characterized. The designed wall panel component was prototyped in full scale to evaluate the molding process and the final quality of the product. Preliminary results obtained with the pilot experiment demonstrated that the composite had properties and values that met the requirements of the standards EN 312:2010 and NBR 14810-2:2013, for structural boards for use in humid conditions (type P5). To prove the ecological aspect of the product, CO2 emissions resulting from its manufacture and the amounts of carbon of non-fossil origin and fixed by it (expressed as CO2 uptake) were calculated. The final balance proved to be favorable.
