“…The adoption of engineered wood products, such as particleboards, cross laminated timbers, and so on, represents a greener solution when compared with timber, keeping almost the same properties [2]. In some cases, engineered wood products (e.g., glued wood composites) are superior to natural wood in terms of structural and material properties.…”

“…Considering the analysis based on the equivalent thermal performance of the panel, 0.46 and 0.185 kg of CO 2 are obtained, respectively. In order to compare the panels with other natural or synthetic solutions, it is possible to note an environmental impact quite low for the wooden panel, both with standard and flour glues (Table 3) [2,52]. Lower values are obtained for other similar panels with agricultural waste but the final environmental impact index is deeply influenced by the distances between the raw materials and the fabrication place (these distances are very low for coffee chaff and hempy-based panel, characterized by the lowest values of GWP).…”

Eco-Sustainable Wood Waste Panels for Building Applications: Influence of Different Species and Assembling Techniques on Thermal, Acoustic, and Environmental Performance

2021

Multiple high quality wood waste from a window manufacturer is identified and collected. Eco-sustainable panels, with promising acoustic and thermal insulating performance, were then fabricated. The available wood is of different tree species (pine, oak, and mahogany) and size (pieces of wood, mixed coarse chips, and mixed fine chips). Moreover, scraps of olive tree pruning from local areas were collected for reuse. The aim of the research is to assembly panels (300 × 300 mm2) both with different techniques (hand-made and hot-pressed) and type of adhesive (vinyl and flour glues) and to evaluate their thermal, acoustic, and environmental performance. All the panels present thermal and acoustic performance comparable with the similar ones available in the literature or with commercial solutions. The thermal conductivity varies in the 0.071 to 0.084 W/mK range at an average temperature of 10 °C, depending on the tree species, the assembly technique, and regardless of the type of adhesive used. Oak wood panels are characterized by both better sound absorption (α peak value of 0.9, similar to pine pressed sample with flour glue) and insulation (transmission loss up to 11 dB at 1700 Hz) properties. However, their added value is the low environmental impact assessed through life cycle analysis in compliance with ISO 14040, especially for panels assembled with natural glue.

“…Many studies have regarded the application of castor oil-based polyurethane resin for particleboard production, for example, in single-and multiple-layer panels (Iwakiri et al 2012;Bertolini et al 2014;Bueno 2015;Fiorelli et al 2019;Brito et al 2020;Da Silva et al 2021), mixed with residues or lignocellulosic products (Cravo et al 2015;Gava et al 2015;Buzo et al 2020;Sugahara et al 2020;Bispo et al 2022). The market cost of this resin is the main barrier cited by these authors, but such a condition might be reversed through the intensification of commercial applications of castor oil-based resins.…”

“…The panel mats were heat-pressed at a pressure of 5 MPa and a temperature of 100 °C for 10 min, with a 30 s period after the initial 5 min to depressurize and, consequently, release gases from the interior of panels, as suggested by Sugahara et al (2020) and Buzo et al (2020). For each treatment (T1 and T2), three panels were made.…”

Tectona grandis wood presents decent dimensional stability as well as highly suitable physical and mechanical properties. These characteristics have encouraged the intense usage of this species, which also includes the reuse of wood processing waste for panel production. Using teak wood waste, this study aims to manufacture and evaluate heat-pressed particleboards at 5 MPa and 100 °C, by being glued with castor oil-based polyurethane resin at proportions of 10% for the homogeneous boards and 12% for the heterogeneous solutions. Single-layer (homogeneous) boards were compared with three-layer particleboard specimens (heterogeneous) having the finer particles in the outer layers. The basic density, moisture content, modulus of rupture and modulus of elasticity in the static bending and perpendicular tensile, water absorption, and thickness swelling after 24 h were evaluated to support this comparative study. All the manufactured particleboards met the standardized requirements of performance, thus being very feasible for usage as non-structural boards. When the two different compositions were analyzed, a considerably better performance of the three-layered particleboards was identified when compared to the homogeneous panels.
