This study addresses the pressing need for renewable, biodegradable, and ecologically advantageous materials by harnessing olive-pomace fibers, an often-discarded byproduct of the olive oil extraction process. This investigation underscores the potential of repurposing these waste fibers as reinforcement agents in biocomposite materials. To unleash this potential, olive-pomace fibers were incorporated into a novel matrix composed of cornmeal. The research was spearheaded by the initial characterization of olive-pomace fibers, followed by the formulation and fabrication of biocomposite materials using the fibers in a cornmeal matrix. Subsequently, the mechanical integrity of the biocomposite was rigorously evaluated using Charpy impact tests on standard test specimens. A superior mechanical performance was observed in a specific formulation, labeled as MC40/OP5, which consisted of a 40% cornmeal and glycerol matrix reinforced with 5% olive-pomace fibers. Remarkably, the MC40/OP5 formulation demonstrated a Charpy impact strength of approximately 31.25 KJ/m² . This value surpassed the impact strength of both the MC40 formulation, which consisted of 40% glycerol alone, and the MC40/OP10 formulation, which was reinforced with 10% olivepomace fibers, by factors of 2.1 and 1.3 respectively. The implications of this research are considerable for the evolution of sustainable materials. The successful integration of olive-pomace fibers as reinforcement in biocomposites illuminates a prospective path for agricultural waste utilization to augment material properties. The enhanced mechanical performance of the MC40/OP5 formulation suggests promising avenues in areas requiring elevated impact resistance. In conclusion, this investigation contributes significantly to the ongoing endeavors in developing eco-friendly materials with enhanced mechanical characteristics, thereby bolstering environmental sustainability and resource efficiency.

“…Moreover, date palm fibres have been explored as potential reinforcement in polymeric matrices since the eighties [6]. Several thermal, mechanical, and microstructure studies on the different parts of the date palm tree were studied [7][8][9][10][11][12]. Within this context, Awad et al [13] elaborated a critical review of date palm trees from fibres to their uses in biocomposites.…”

This study focuses on the reduction of the environmental impact of plastic waste and the valorisation of vegetal wastes produced annually from date palms. This paper presents an experimental study on the manufacturing of composite panels based on date palm leaflets, DPL, and expanded polystyrene wastes were carried out. Hot compression process was proposed with the aim of improving the composite manufacturing techniques previously released by the team using a cold compression process. Three composites were studied with the weight fraction (wt.%) of 70, 75 and 80 of the DPL as a reinforcement. The weight fraction of expanded polystyrene is respectively 30, 25 and 20 wt.%. Physical and mechanical characterizations of biocomposites were performed with the reinforcement size between 0.315 mm and 0.5 mm. The result shows that the composite panels have a low density between 414 and 511 kg/m 3 . The composite panels showed an improved maximum stress and flexural modulus that can reach 6.18 MPa and 13.5 MPa respectively. These values are comparable to the literature values such as Medium Density Fibreboard (MDF) (13.5-25 MPa) and the Durian Peel and Coconut Coir (DPCC) particleboards (0.8-22.4 MPa), (0.7-43 MPa). However, the water absorption result ranging from 77 to 95 % shows that the studied composite panels are sensitive to moisture and exhibit high moisture uptake percentage thus limits their possibility of use in moist condition.

The investigation of the characterization of Adansonia digitata biomass from pyrolysis in a fixed-bed tubular carbon steel reactor at temperatures of 400℃ to 700℃. Firstly, proximate, ultimate, and heating value analyses of the raw biomass were obtained prior to experimental runs via the fast pyrolysis process; thereafter, the quality of the bio-oil and biochar yields for bioenergy and industrial applications was investigated using the following analyses: higher heating values (HHV), lower heating values (LHV), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). Optimum bio-oil (52.70 wt%) and bio-char (40 wt%) yields were obtained at temperatures of 500 and 400℃, respectively. GC-MS analysis of the yielded biooil revealed a higher percentage of oleic acid, phenol, methanol, and ketone among the fuel compositions, whereas the bio-oil chemical composition includes carbon (70.99%), hydrogen (13.40%), nitrogen (0.54%), oxygen (15.01%), and sulfur (0.06%), flash (81) and pour points (-7) for bio-oil with HHV (30.75 MJ/kg) and LHV (27). The results obtained demonstrated that the properties of products can serve as a waste management strategy, sorbent, soil enhancer, and biofuel industry application.
