Special Issue Information

Dear Colleagues,

Increased environmental consciousness, enhanced interest towards the application of sustainable production technologies, the increased shortage of natural resources, and recent strict environmental regulations have forced many manufacturing industries to search for new eco-friendly materials from renewable resources, in order to substitute conventional materials in a number of end uses. This growing need for ‘green’ materials and sustainable products has also led to the increased production and utilization of eco-friendly wood-based composites worldwide. According to the latest forecast data by the Food and Agriculture Organization, the overall demand and consumption of wood and wood-based materials by 2050 is projected to increase by 37% compared to 2020. The contemporary principles of the circular economy have imposed new, stricter requirements on all aspects of product design and development, including the production of wood-based composites. The new legislative requirements in the field of waste management have increased the demands for new, innovative, eco-friendly materials and products. In this respect, the “cascading” use of wood, optimization of production technologies, and recycling and secondary utilization of waste and by-products are important issues related to the economic profitability and sustainable development of woodworking and furniture industries, in line with the principles of the circular bioeconomy.

This Special Issue, “Advances in Wood-Based Composites from Alternative Lignocellulosic Raw Materials”, is aimed at collecting high-quality original research and review articles on topics including (but not limited to) the latest approaches in wood waste and by-product utilization; the development of wood waste-based composites; advanced recycling of post-consumer solid wood and wood-based composites; the cascading use of wood; life cycle assessments of wood composites; wood–polymer composites; the valorization of wood bark for value-added chemicals and the production of high-performance wood composites; biodegradable, eco-friendly wood-waste-based composites; the application of nanomaterials to wood composites; non-wood lignocellulosic composites; and advanced functionalities and application of wood-waste-based composites.

We strongly encourage contributions from researchers and experts from all related fields in the form of original research works or review articles.

This study explores the potential of using underutilized materials from agricultural and forestry systems, such as rice husk, wheat straw, and wood strands, in developing corrugated core sandwich panels as a structural building material. By leveraging the unique properties of these biobased materials within a corrugated geometry, the research presents a novel approach to enhancing the structural performance of such underutilized biobased materials. These biobased materials were used in different lengths to consider the manufacturing feasibility of corrugated panels and the effect of fiber length on their structural performance. The average lengths for wood strands and wheat straws were 12–15 cm and 3–7.5 cm, respectively, while rice husks were like particles, about 7 mm long. Due to the high silica content in rice husk and wheat straw, which negatively impacts the bonding performance, polymeric diphenylmethane diisocyanate (pMDI), an effective adhesive for such materials, was used for the fabrication of corrugated panels. Wood strands and phenol formaldehyde (PF) adhesive were used to fabricate flat outer layers. Flat panels were bonded to both sides of the corrugated panels using a polyurethane adhesive to develop corrugated core sandwich panels. Four-point bending tests were conducted to evaluate the panel’s bending stiffness, load-carrying capacity, and failure modes. Results demonstrated that sandwich panels with wood strand corrugated cores exhibited the highest bending stiffness and load-bearing capacity, while those with wheat straw corrugated cores performed similarly. Rice husk corrugated core sandwich panels showed the lowest mechanical performance compared to other sandwich panels. Considering the applications of these sandwich panels as floor, wall, and roof sheathing, all these panels exhibited superior bending performance compared to 11.2 mm- and 17.42 mm-thick commercial OSB (oriented strand board) panels, which are commonly used as building materials. These sandwich structures supported a longer span than commercial OSB panels while satisfying the deflection limit of L/360. The findings suggest the transformative potential of converting renewable yet underutilized materials into an engineered concept, corrugated geometry, leading to the development of high-performance, carbon-negative building materials suitable for flooring and roof applications.

Limestone (LS) and stabilised secondary spruce chips (SCs) utilisation in wood–cement composites is still an unexplored area. Therefore, the main objective of the research presented here is the assessment of the long-term behaviour of cement-bonded particleboards (CBPs) modified by LS and SCs. Cement (CE) was replaced by 10% of LS, and spruce chips by 7% of SCs. The test specimens were stored in a laboratory and exterior environment (Middle Europe) for up to 2 years. The density, strength, and modulus of elasticity were evaluated after 28 days, and then in 6-month periods. The hygroscopicity was analysed separately. The mineralogical composition and microstructure were analysed due to possible LS participation during hydration. SC synergic behaviour in CBPs was also studied. After 2 years, the microstructure of the CBP was more compact, and denser. Strong carbonatation contributes to the improvement of CBP properties. The products of carbonatation were present in both the matrix and wood chips. The hydration of the matrix was almost finished. LS has a positive effect on the matrix microstructure development. LS acts both as an active component participating in the formation of the cement matrix structure and as an inert microfiller, synergic with hydration products. SCs have a positive effect on the hygroscopic behaviour of CBPs and slightly negative effect on the tensile strength. Full article
