“…And castor oil-based bicomponent polyurethane, that is a biodegradable adhesive with renewable origin obtained from vegetable oil (Barbirato et al 2019a). After production, the experimental OSB was subjected to heat treatment, replacing the use of wood chemical preservatives, which can present potential toxicity (Sugahara et al 2022c).…”

“…In addition to the necessity for more sustainable alternative materials, it is vital to research diverse types of materials and methods to guarantee that the panels meet the requirements (structural, durability, and aesthetic), to be safely employed. Regarding this, it is imperative to study alternative lignocellulosic resources, adhesives, and techniques to assure the resistance against termite attack, replacing chemical preservatives with systems possibly less dangerous, as the heat treatment (Sugahara et al 2022c).…”

The use of wood-based panels such as Oriented Strand Board has grown in civil construction. This follows the contemporary trend towards low environmental impact materials. However, there is a lack of relevant information about their life cycle assessment, appearing as a current and relevant research topic. Experimental panels made with Eucalyptus wood and castor oil-based polyurethane adhesive already demonstrated great physical-mechanical performance. Therefore, this study aimed to continue the evaluation of this innovative product, estimating their potential environmental impacts using life cycle assessment from a cradle-to-gate perspective and comparing the results with traditional panels and literature data. System boundaries, environmental impacts and environmental hotspots were identified using the ReCiPe H method in terms of ten impact categories. Comparing experimental (heat-treated) and traditional panels, the experimental versions performed better in most categories and showed safer behavior in categories related to human health in addition to not using paraffin, termiticide, and other organic chemicals presented in the traditional panels. Though made of different types of adhesives, the adhesive was the main environmental hotspot for both types.

“…However, there is a growing need to produce more sustainable products, justified by the progressive concern with quality, economic, social, and environmental impacts of processes and products [19,20]. In addition, predicting a future shortage in wood supply [21] as a result of high volumes of industrial production using specific species, it is necessary to study the use of different types of lignocellulosic resources [7,[22][23][24], and adhesives of renewable origin without the presence of volatile organic compounds in their compositions [22,24], and the use of more ecological alternatives to chemical preservatives [25][26][27][28].…”

“…The heat treatment can be performed on the strands (pre-treatment) or on the finished board (post-treatment), and the changes in physical and mechanical properties vary according to the method, temperature, time, adhesive content, among other variables adopted, not following a specific standard [20].…”

“…There are also few studies evaluating the effects of thermal treatment of OSB produced with alternative adhesives from renewable origin, without the presence of solvents and volatile organic compounds in their compositions. Thus, due to the scarcity of studies in this area, this is considered a promising research field that requires attention, and it is essential to conduct studies with the purpose of developing knowledge about the effect of thermal post-treatment on OSB, evaluating the consequences of this type of process and ensuring the safety of products developed with this methodology [20].…”

In view of the lack of studies aimed at producing and assessing the effects of heat treatment of Oriented Strand Board (OSB) panels, this paper evaluated the thermal degradation kinetics of the raw materials, and the physical and mechanical properties of the panels made with eucalyptus wood and castor oil-based polyurethane adhesive. The OSB panels were subjected to post-production heat treatment (at 175 and 200 °C), replacing the use of wood chemical preservatives. Furthermore, the quantity of materials varied in the face:core:face layers in the proportions of 25:50:25 and 30:40:30, aiming to evaluate the possibility of structural applications for the panels. The results were statistically analyzed and compared with the specifications and classifications for OSB indicated by the European Standard EN 300 and the literature. The application of heat treatment improved the physical properties by decreasing the interaction with water and did not reduce the mechanical properties below the recommended levels. The variation in layer proportions indicated that all of them can be adopted without compromising the panel’s physical-mechanical performance. All treatments are compatible with the EN 300 classification for OSB/4 (heavy duty load-bearing boards for use in humid conditions), presenting technical feasibility and excellent structural profile for civil construction applications.
