“…The measurements were carried out at 40 kV and 20 mA, with a detector mounted on a goniometer scanning scale from 10 to 60°, at a scanning speed of 5° min −1 by applying monochromatic CuKα radiation (λ = 1.5406 nm). The crystallinity degree was then measured as explained in an earlier study [ 17 ].…”

“…The properties of composites depend on a variety of factors such as the fiber–matrix adhesion, fiber length, fiber content (loading), fiber treatment, and fiber dispersion in the matrix [ 12 , 13 , 14 , 15 ]. When manufacturing natural-fiber-reinforced polymer composites, weak interfacial bonding occurs between the natural fibers and polymer matrices owing to the hydroxyl groups in natural fibers [ 16 , 17 , 18 ]. Extensive studies have been performed to understand the effect of chemical treatment on natural fibers.…”

The search for renewable alternatives for petroleum products that can be used in industrial applications is increasing. Each year, several tons of bio-derived industrial waste is produced and most of it is burned or placed in landfills. Olive pits (OP) have unique characteristics such as abundance, renewability, and biodegradability, which can be utilized to develop new types of biocomposites. One of the most promising uses of OP is that they can reinforce the mechanical properties of polymeric biocomposites. This study describes the preparation of recycled low-density polyethylene (rLDPE) that is filled with OP flour (10, 20, 30, and 40 wt.%) using a twin-screw extruder. The effects of the chemical treatment of the OP surface (sodium hydroxide (NaOH) and dimethyl sulfoxide (DMSO)) on the bio-filler/polymer compatibility along with the produced composite’s chemical, physical, mechanical, and thermal properties have been explored. Overall, the reinforced composites that were obtained with alkali-treated OP have better biocomposite properties. This indicates an improved compatibility between the bio-filler and matrix. The results are promising in terms of using OP flour in developing green composites.

“…Polymer functionalization is usually performed in the extruder during the melting phase, combined with the application of chemical functional groups for a specified time duration. Key parameters affecting functionalization include initiators such as peroxide, coupling agent contents such as MAH, polymer geometry such as size, 177 state of functionalization (melt state or solid state), temperature, and time. Efficiency indicators for optimal functionalization are yield, MFI, carboxylic index, and stability indicator.…”

Owing to economic and environmental benefits, new generations of materials/commodities follow “from waste to wealth” strategy. Recently, there has been a huge upsurge in research on the development of eco‐composites using recycled plastic polymers and agro‐residues because the eco‐composites satisfy the stringent environment regulations and are cost‐effective. Herein, we present a detailed review on the potential use of several types of natural fillers as an efficient reinforcement for recycled plastic polymers. In particular, the characterization of different categories of eco‐composites according to their morphological, physical, thermal, and mechanical properties is extensively reviewed and their results are analyzed, compared, and highlighted. Furthermore, a framework to produce functional eco‐composites, which includes functionalization of ingredients, critical issues on microstructural parameters, processing, and fabrication methods, is outlined and supported with sufficient data from the literature. Finally, the review outlines the emerging challenges and future prospects of eco‐composites to be addressed by interested researchers to bridge the gap between research and commercialization of such a class of material. Overall, the acquired knowledge will guide researchers, scientists, and manufacturers to plan, select, and develop various forms of eco‐composites with enhanced properties and optimized production processes.

“…Date palm agroresidues are perhaps the most abundant (40 Kg/tree per annum) and least expensive ($0.1/Kg) agroresidues worldwide, which are still not well-utilized. Natural bers extracted from date palm agro-residue are characterized by their modest material properties and cost effectiveness relative to other types like coir, hemp and sisal bers (Rajeshkumar et al 2020;Nassar et al 2021). Proper integration of date palm bers with numerous polymeric materials resulted in improved mechanical, physical, thermal, and acoustic properties of developed bio-composites (Masri et al 2018;Dixit et al 2020).…”

This article reports a new chemical treatment method to extract rich cellulosic fibers from date palm agro-residues. The technique comprises a multistep process which is quite unique, efficient, sustainable, and capable of producing high-performance natural date palm fibers. In specific, it consists of three consecutive steps: dewaxing, acetylation, and mercerization, which are carried out in a strict sequence. Each step is designated to achieve a specific goal in preparation for the next step. In addition, procedures have been adjusted from its initial state by incorporating input parameters that are configured experimentally to optimize outputs via the design of experiment approach. The method has been applied in two variants with respect to heating mechanism: conventional heat-assisted and microwave heat-assisted sources. An experimental characterization of mechanical, physical, and thermal properties of the treated fibers exhibited a significant enhancement over the untreated counterparts which confirms the potency of the new process.
