“…Of the three board manufacturing variables, the particle size affects density, MOR, MOE and IB; the pressing time affects MOR, IB, TS and WA; and the pressing cycle affects MOR, MOE and IB. The particle size for manufacturing the boards has become the most important factor in the tests performed by the investigators, and it can be concluded that better properties are achieved with a smaller particle size [46], as shown in this work.…”

The giant reed (Arundo donax L.) is considered one of the world's 100 worst invasive species. The main method by which this species propagates is by growth of scattered fragments of rhizome, spreading without control with very strong, deep roots. Agricultural waste consists of lignocellulosic materials that can substitute natural wood and offer a suitable alternative with which to manufacture boards for furniture, packaging and building purposes. The objectives of this work were to obtain binderless particleboards using giant reed rhizome as the raw material, to evaluate their mechanical and physical properties according to the applicable European standards and to assess the self-binding mechanism of the particles in the board. Six types of boards (12 classes) were manufactured with giant reed rhizome biomass. They were manufactured with a temperature of 110 • C, a pressure of 2.5 MPa and pressing times of 7 and 15 min, applying one or two pressing cycles. The results achieved for modulus of rupture (14.2 N/mm 2 ), modulus of elasticity (2052.45 N/mm 2 ) and internal bonding strength (1.12 N/mm 2 ) show that the mechanical properties were improved by using a smaller rhizome particle size and two pressing cycles.

“…Their results showed a large increase in MOE, satisfactory values of MOR and IB, and a low TS value, probably due to the nature of the curing resin. Hegazy and Ahmed and Hegazi et al [14,15] studied the influence of density on the strength of panels produced with date palm fibers at 140 • C for 10 min and 160 • C for 8 min with the same resin dose. Better strength (MOR, MOE and IB) was achieved in both cases with higher densities.…”

“…Several studies have been conducted focusing on the manufacturing of building materials using different palm residues. Particleboard with synthetic adhesives and different manufacturing procedures have been studied using fibers or chips of date palm [7][8][9][10][11][12][13][14][15], washingtonia palm [5,[16][17][18], and canary palm [19][20][21]. Other studies have been performed using date palm pruning waste as a reinforcement in concrete [22][23][24], in gypsum [25], and in the manufacturing of different composites [25][26][27].…”

Palm trees are very fast-growing species. Their management produces annually a large amount of biomass that traditionally has been either disposed of at dumping sites or has been burnt onsite. This paper presents an experimental study to obtain particleboard using this biomass in a low energy process (short pressing time and low pressing temperature), using particles of different sizes from the rachis (midrib) of the three palm species most representative of urban gardening in Spain: canary palm (Phoenix canariensis hort. ex Chabaud), date palm (Phoenix dactylifera L.) and washingtonia palm (Washingtonia robusta H. Wendl). Their physical and mechanical properties were tested, and the feasibility of their use as a construction material was evaluated. The results showed that the manufactured particleboard had similar performance to conventional wood particleboard and good thermal insulation properties. Boards made with the canary species showed better mechanical performance. The properties of the particleboard depended on the particle size and species. The use of the pruning waste of palm trees to produce durable materials such as particleboard could be beneficial to the environment since it is a method of carbon fixation, helping to decrease atmospheric pollution and reducing the amount of waste that ends in dumping sites.

“…Le bois fibreux de la palme est utilisé comme une alternative aux déchets de bois classique dans la fabrication des différentes plaques de bois industriel (MDF, HDF, LDF…). Cette technique est utilisée par nombreux fabricants industriels dans le monde [36][37][38]. D'autre part, les fibres extraites du bois fibreux de palme attirent l'intérêt des chercheurs pour être utilisés comme renfort dans les matériaux composites [39][40][41].…”

La disponibilité en quantité importante des sous-produits renouvelable des palmiers dattiers laisse envisager leur utilisation comme renfort dans les matériaux composites et les structures d’isolation. Ceci nécessite la caractérisation physico-mécanique des différentes composantes du palmier. Dans ce contexte, cette étude a été entamée pour la caractérisation d’une composante importante du palmier qui est la palme mûre. La palme étant décomposée essentiellement en deux parties, le Pétiole et le Rachis, la caractérisation a été portée alors sur le bois fibreux et les fibres de ces deux parties. La caractérisation physique concernera la masse volumique des fibres et de la matrice végétale (lignine) ainsi que le taux d’humidité dans les différentes parties de la palme. Les essais mécaniques ont permis de déterminer les caractéristiques mécaniques du bois fibreux et des fibres extraites des deux parties de la palme après le séchage. À l’issue de cette étude, les résultats obtenus montrent l’influence de la position de l’échantillon testé sur les propriétés physico-mécaniques. Ils ont permis également de situer ce type de bois fibreux et ces fibres parmi d’autres résultats de la littérature scientifique et d’envisager de les utiliser dans la mise en œuvre des matériaux composites et dans des éléments d’isolation.
