Particleboards production from date palm biomass

Abstract

Date palm biomass is a renewable natural resource that has not widely been utilized in industry. The objective of this study was to examine some chemical properties of date palm trunk and rachis (holocellulose, cellulose, lignin and extractives) and to evaluate their suitability to produce composite panels. Particleboards were produced using trunk and rachis as an alternative raw material for forest products industry in the presence of two types of polycondensation resins (phenol-formaldehyde and melamine urea-formaldehyde) which were selected as binding agents. The panels were tested for their physical (water absorption and thickness swelling) and mechanical (modulus of rupture, modulus of elasticity and internal bond strength) properties. The internal bond strength of date palm trunk and date palm rachis based boards met the requirements of the general purpose product standards (EN 312) at 0.70 g/cm 3 density. The panels made with phenolformaldehyde resin showed better performance with respect to the panels made with melamine urea-formaldehyde. In addition, the particleboard made with date palm trunk particles had better quality compared to the particleboard made from date palm rachis particles. Based on preliminary results of this work, raw materials from date palm trunks and rachis can have a promising potential in the manufacture of particleboards and as a substitute for wood in board production.

Chemical Analysis of Different Parts of Date Palm (Phoenix dactylifera L.) Using Ultimate, Proximate and Thermo-Gravimetric Techniques for Energy Production

“…The higher extractives content of PL may be attributed to its open anatomical structure, which is accessible to the chemicals. These values are close to the values obtained on midribs of five date palm cultivars [7], and on some lignocellulosic residues [36], while they are lower than those reported for date palm trunk (PT) and rachis [11]. There is very little information to compare chemistry of the different parts of date palm residues, but the results found in this work are in partial agreement with previously published studies on non-identified date palm cultivars [17,50].…”

“…It can be seen that PT, PFB, FS and DPS had lower cellulose content than typical wood species, while the other parts fall in the range of these wood species. These results are in accordance with the findings of a previous work carried out by Amirou et al [11] on two date palm residues (trunk and rachis) and [7] on the midrib of five date palm cultivars. However, these values are lower than those reported for some lignocellulosic residues [36].…”

“…Although no results are available in the literature for comparison with our data in this study, these results are in partial agreement with the findings of previous works [7,11,15,16,36,43].…”

“…The lowest values of hemicelluloses were recorded with PC and PL (12.6% and 16.1%, respectively), while the highest values were obtained with PT, PFB and DPS (Table 2). These results agree with previously reported data [7,11,13,15,16,50]. * Each value is an average for 10 specimens and the values between brackets are standard deviations.…”

Potential Use of Phoenix canariensis Biomass in Binderless Particleboards at Low Temperature and Pressure

“…Particleboards have been generated using various species of palm trees as the main material such as date palm (Nemli et al 2001;Hegazy and Aref 2010;Amirou et al 2013;Saadaoui et al 2013;Hegazy et al 2015), Washingtonia palm (García-Ortuño et al 2013), and oil palm (Laemsak and Okuma 2000;Hashim et al 2011a;Rasat et al 2011;Suhaly et al 2012;Wad Nadhari et al 2013;Jumhuri et al 2014;Henao et al 2014;Tajuddin et al 2016). The behavior of the particleboard depends on the species of palm tree and the origin of the particles from the trunk or the leaf.…”
