“…Natural origin adhesives may include starch, sucrose, glucose, chitosan, lignin, tannin, protein, gums and citric acid and have been used in numerous studies [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. Application of adhesives based on natural components gives satisfactory results in terms of mechanical strength properties, while inferior properties are observed in terms of water soaking or swelling in thickness [42][43][44]. Since most cited studies concern tests conducted on plywood or particleboards of densities exceeding 600 kg/m 3 , swelling in thickness may be crucial in this case.…”

In this study, the possibility of using adhesives of natural origin for the manufacture of wood fiber-based lightweight panels was investigated. The boards, of a density ranging from 150 to 250 kg/m3, were glued together using commercial urea–formaldehyde resin (control board), solutions of rye flour and potato starch and two types of starch: oxidized and gelatinized. The density and density profile, compressive strength, modulus of elasticity, acoustic properties and thermal conductivity were determined in the produced boards. These studies show that when food components are used as binding agents in the manufacture of lightweight wood fiberboards, the properties obtained can be comparable with those of commercial boards manufactured using synthetic agents.

“…Results presented in Table 1 show that MOR for bioboards ranges between 0.27 and 1.10 MPa. The MOR obtained are much lower than 10 MPa which is stated as the lowest MOR value for interior fitments by ANSI A208.1 [26]. Table 4 presents the ANOVA for the MOR.…”

“…One of the most significant physical qualities of particle boards is density, which is affected by the density of the biomass utilised, the binder used, and the pressure exerted during pressing [26]. From results in Table 1, the density of the manufactured bioboards varied from 524.69 to 738.10 kg/m 3 .…”

“…Observation of the responses in Table 1 reveal that MOE of sawdust bioboards reached 100.4 MPa at highest pressure and temperature setting and pressing time of 10 minutes. According to Mitchual et al [26], ANSI A208.1 specifies minimum MOE for particle boards for general usage and furniture manufacture of 1550 MPa as the minimum value. The ANOVA for the MOE of the boards is shown in Table 3.…”

The production of particleboards without the use of synthetic binders is desirable to prevent environmental problems. This study has produced experimental binderless boards from untreated sawdust from Abura wood using a laboratory press. Response Surface Methodology using Box-Behnken experimental design was utilized to investigate the influenceof pressing variables (pressure, pressing temperature and pressing time). Density of the bioboards produced wasbetween 523.69 and 738 kg/m3which was comparable tomedium density fibreboards. The maximum values for Internal Bonding Strength (IB), Modulus of Rupture (MOR)andModulus of Elasticity (MOE) were 0.049 MPa,1.1 MPaand100.4 MPa, respectively. It was shown that, for the range of factors studied, pressure and the pressing temperature were the more significant factors in determining the density, MOE and IB. This study showed that the sawdust can potentially be used for the manufactureof binderless boards.

“…Previous studies have indicated that the mechanical properties of fiberboards positively correlate with the aspect ratio (particle geometry) of the biomass materials. This is because of its greater surface area regarding contact between particles (Bax and Mussig 2008;Juliana et al 2014;Mitchual et al 2020). Wood particles with a higher aspect ratio enhance stress transfer from the polymer matrix to the particles, improving the composite mechanical properties.…”

This paper presents significant findings on the variation in the anatomical properties of Anthocleista grandiflora wood, which could greatly influence its utilization in various products. Cubic-shaped heartwood and sapwood specimens were extracted at the base, middle, and top of boles from 38-, 43-, and 47-year-old trees. The variations in cell morphology and anatomical characteristics were meticulously assessed. The specimens were prepared into 3 mm x 10 mm fragments, macerated, and viewed under a microscope using Motic Image plus 2.0 ML software. The following parameters were determined: average values of fiber length, fiber diameter, lumen width, double fiber wall thickness, Runkel ratio, aspect ratio, coefficient of rigidity, and coefficient of flexibility of trees at the base, middle, and top. Notably, there were more vessels in sapwood than in heartwood, and the vessel areas increased with increasing vessel lengths. The results also revealed that in the heartwood region, the fraction of vessel lumen increases with tree age in the base, middle, and top sections. These findings are significant as they provide a comprehensive understanding of the anatomical properties of A. grandiflora wood, which is classified as wood from numerous vessels, a common characteristic of noble woods. The wood exhibited anatomical properties suitable for cellulose, paper, and fiber-based products, highlighting its potential in various industries. Keywords: wood quality; fibers; morphological characterization; timber industry. Variação das características anatômicas da madeira de Anthocleista grandiflora em função da idade e da posição no troco RESUMO: Objetivou-se avaliar as propriedades anatômicas da madeira de Anthocleista grandiflora e as suas possíveis aplicações. Amostras do cerne e alburno foram extraídas na base, meio e topo de árvores com 38, 43 e 47 anos de idade. Em seguida, foram avaliadas variações na morfologia celular e nas características anatômicas, por meio de fragmentos de 3 mm x 10 mm, macerados e visualizados em microscópio utilizando o software Motic Image plus 2.0 ML. Foram avaliados: comprimento da fibra, diâmetro da fibra, largura do lúmen, espessura da parede dupla da fibra, razão de Runkel, razão de aspecto, coeficiente de rigidez e coeficiente de flexibilidade das árvores na base, meio e topo. Verificou-se mais vasos no alburno do que no cerne, e as áreas dos vasos aumentaram com o aumento de seu comprimento. Os resultados obtidos também indicaram que na região do cerne a fração do lúmen dos vasos aumenta com a idade árvores nas seções da base, intermediária e topo, sendo os valores de 14.76, 11.38 e 20.73 mm para 38 anos; 23.74, 22.13 e 23.09 mm para 43 anos; 28.62, 12.89 e 25.01 mm para 47 anos. A A. grandiflora foi classificada como madeira de numerosos vasos, característica comum para madeiras nobres. A madeira apresentou propriedades anatômicas adequadas para celulose, papel e produtos à base de fibras. Palavras-chave: qualidade da madeira; fibras; caracterização morfológica; indústria madeireira.
