“…Furthermore, bio-based composites can be easily attacked by microorganisms due to their chemical composition, their organic nature, and their pH [81,82]. Apart from the aesthetic impact, a biological attack can lower the durability of composites, affect the materials' properties, and restrict their performance, modify their chemical compositions, and compromise their natural structures [83]. Furthermore, biological degradation can affect human health, causing diseases and lowering indoor air quality [84,85].…”

The internal structures and the hygroscopicity of bio-based boards consisting of giant reed (Arundo donax L.) and hazelnut shells as bio-aggregates, and a sodium silicate solution as the adhesive, were investigated. The aim was to evaluate the influence of each material (the bio-aggregates and adhesive) and their distributions in the boards on the final performance. By carrying out X-ray computed tomography, the internal structures and the porosities of the boards were determined, allowing important considerations of their hygroscopicity. The voids’ percentages were between 26% and 36% of the total volume of the composites. Both the materials and the composites demonstrated high hygroscopicity. In particular, the mixtures of the bio-aggregates and the sodium silicate allowed reaching a moisture buffering value of 7.44 g/(m2%RH) for the A. donax-based composite, 3.86 g/(m2%RH) for the hazelnut-shell-based composite, and 4.65 g/(m2%RH) for the mixture-based composite. Besides the identification of the contributions of the materials, a detailed discussion of the assessed properties was carried out to use these bio-based boards in vernacular historic construction. The results show how the aggregate type and the adhesive content affected the final behavior, demonstrating the importance of a conscious material choice. Furthermore, helpful information for the future development of these types of bio-based boards and their possible optimization was provided.

“…The ANOVA results showed that the polyurethane content and particle size composition in the manufacture of CBP did not significantly affect the resistance against fungi attacks. The whiterot fungi can aggressively degrade all components used to manufacture composite (Gonçalves et al 2021). Polyurethane is one of the adhesives susceptible to degradation.…”

Wood biomass such as sawdust, particles, and chip obtained wood industry can be used as raw material for chip block pallets (CBP). This study evaluated the resistance of chip block pallets made from teak-sawn waste and polyurethane adhesive against decay fungi (white-rot and brown-rot fungi) and subterranean termites. The CBPs with dimensions of 9 × 9 × 9 cm and a target density of 0.6 g/cm3 were cold pressed at 9.8 MPa for 4 h using several polyurethane concentrations and composition of particle sizes. The termite and decay resistance tests were conducted following JIS K 1571 2004. The results showed that CBP treated with different polyurethane concentrations and composition of particle sizes was resistant to subterranean termite attacks. However, the CBP manufactured were not resistant to white-rot and brown-rot fungi attacks, showing more than 3% mass loss percentage. Considering the efficiency of polyurethane use, the study suggested the best content for using polyurethane in the manufacture of CBP is 4.5% with a particle size composition of 50 (4-14 mesh): 50 (> 60 mesh).

“…The union of different organic [ [12] , [13] , [14] , [15] ] and inorganic materials [ 16 , 17 ], if pressed under high temperature and pressure, can generate a panel resistant to physical or mechanical stress and xylophagous organisms, in addition to promoting better disposal of commercially undervalued waste through ecologically correct environmental management. Among several organic materials used in the composition of particleboards, along with wood, rice husk [ 15 , 18 ], sugarcane bagasse [ 19 ], wheat bran [ 20 ], coffee fiber [ 21 ], bamboo waste [ 22 ], sunflower stalks [ 23 ] and, in particular, eggshell, stand out [ 24 ].…”
