“…Steam explosion was one of the most effective methods to disrupt lignocellulosic structure in an environmentally friendly way. Researches have also shown that steam explosion could generate cavities or micropores inside the fiber matrix, loosen the cell wall microstructure, and improve cholesterol and ion adsorption capacities ( Ouyang et al, 2023a ; Vitrone et al, 2022 ; Wang et al, 2021 ). Therefore, in this research, steam explosion technology will be introduced to modify RBIDF and improve functional properties.…”

“…The foam’s flame resistance was quantitatively examined using an LOI tester (Qinsun Instruments Co., Shanghai, China) that conformed with ASTM D2863. Due to its effectiveness in evaluating the property of fire extinguishment, LOI has been a powerful method to quantify material’s flame resistance, , when other methods such as cone calorimetry are not available but should be employed in the future for benchmarking. The samples were cut following type II specimen requirements.…”

Global efforts to reduce carbon emissions and improve thermal comfort demand sustainable and safe-to-use insulative materials. This study advances a new type of chemical binder-free lignocellulose/clay composite foam as a sustainable alternative to the currently used synthetic and glass/mineral counterparts. Pressurized disk milling unraveled submicron "hairy" fibrillation on the surface of refiner mechanical pulp (RMP). Such fibrillated fibers were then subjected to a foam laying process, with kaolinite being incorporated as an efficient and cost-effective fire retardant. Upon oven drying, the foams display suitable structural and mechanical robustness. Through mild fibrillation treatment of the RMP, a clay retention of up to 2-fold by weight was achieved without compromising the properties of the foam, removing the need for the addition of chemical binders. The foam density, mechanical and thermal properties, and flame resistance were systematically investigated with respect to the relative fiber loading as well as surfactant and clay addition. A low thermal conductivity (43.7 ± 0.7 mW/(m•K)) and high flame resistance (limiting oxygen index of ∼43%) were demonstrated for hybrid foams of apparent density of 136 ± 1 kg/m 3 that also displayed good compressive strength (Young's modulus of 0.805 ± 0.158 MPa and compressive stress of 0.126 ± 0.008 MPa at 25% strain). Remarkably, owing to the absence of chemical binding, facile recyclability was demonstrated over three cycles, with no significant reduction in performance. Overall, this work proposes a readily scalable technology toward safe-to-use, recyclable lignocellulose/clay composite foams for building insulation.

“…Among the hydrothermal pre-treatments, steam explosion (STEX) has been used for years, as the Masonite process, in the production of fiberboards [ 35 ]. Hence, STEX already showed its applicability in this field, especially in the production of hardboards through wet processes, with many examples available in the literature, and applications with different materials such as residual softwood [ 36 ], grey alder wood [ 37 ], banana bunch [ 38 ], bamboo chips [ 35 , 39 ], hemp shives and wheat straw [ 19 , 40 ], rice straw [ 41 ], and Arundo donax L. [ 42 , 43 , 44 , 45 ].…”

“…As a first approach, the mechanical and physical properties of MDF made by mixing STEX-AD and conventional WF in different percentages were studied. Indeed, in several studies [ 42 , 44 , 45 , 48 ], high-quality panels were obtained by using STEX-AD. Thus, the purpose of the present work is to identify any enhancements triggered by treating the material, and whether the lack of the adhesive can be compensated when mixing pretreated and untreated materials.…”

This study presents an unexplored method to produce formaldehyde-free MDF. Steam exploded Arundo donax L. (STEX-AD) and untreated wood fibers (WF) were mixed at different mixing rates (0/100, 50/50, and 100/0, respectively) and two series of boards were manufactured, with 4 wt% of pMDI, based on dry fibers, and self-bonded. The mechanical and physical performance of the boards was analyzed as a function of the adhesive content and the density. The mechanical performance and dimensional stability were determined by following European standards. The material formulation and the density of the boards had a significant effect on both mechanical and physical properties. The boards made solely of STEX-AD were comparable to those made with pMDI, while the panels made of WF without adhesive were those that performed the worst. The STEX-AD showed the ability to reduce the TS for both pMDI-bonded and self-bonded boards, although leading to a high WA and a higher short-term absorption for the latter. The results presented show the feasibility of using STEX-AD in the manufacturing of self-bonded MDF and the improvement of dimensional stability. Nonetheless, further studies are needed especially to address the enhancement of the internal bond (IB).
