“…1). The spots on the composite films were silica bodies embedded in the EFB pulp fibers (Gunawan et al 2009;Harsono et al 2016). Hence, more EFB pulp added into the seaweed matrix resulted in more black spots on the surface of the film.…”

Composite materials made from renewable resources can minimize the environmental pollution. In this work, biocomposite films were produced using seaweed as matrix and empty fruit bunch (EFB) pulp fibers as reinforcement. Based on the results, the EFB pulp-seaweed composite films exhibited better mechanical properties than the seaweed film. It was also observed that 50% EFB pulp loading gave the highest tensile strength (81.4 MPa) and elongation at break (5.4%). This phenomenon was supported by SEM analysis, in which more fiber breakage than fiber pull-out was observed on the tensile fracture surface of composite film. Additionally, no agglomeration of the pulp fibers was observed. Instead, the pulp fibers were homogenously distributed throughout the film. In contrast, the contact angle of the seaweed-based films started to decrease once the pulp fibers were added. The decrease in the contact angle was attributed to the hydrophilic nature of the pulp fibers. Nevertheless, the contact angle values of all composite films were still comparatively high and thus, this would not affect their application as a packaging film.

“…This long-chain fatty acid has been identified as palmitic acid (Harsono et al 2016). However, as the EFB material does not actually have oil palm seed and long-chain fatty acids, it is suspected that this long-chain fatty acid originates from the crude palm oil processing process.…”

“…Prehydrolysis (PH) soda cooking has been demonstrated to significantly improve delignification compared to that afforded by soda cooking (Wan Rosli et al 2004). Hence, PH-soda-anthraquinone (AQ) cooking has been developed as an environmentally friendly biorefinery process, because it involves prehydrolysis that aids in removing fragments of hemicellulose and in modifying lignin prior to cooking (Harsono et al 2016).…”

Residual lignin present in alkali pulps prepared from oil palm (Elaeis guineensis) empty fruit bunch was isolated using an enzymatic method and characterized successfully by pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS). These pulps were prepared by sodaanthraquinone (AQ) and prehydrolysis (PH) soda-AQ cooking methods (pulp yields were 45.3 and 33.9%, respectively). Py-GC/MS of the residual lignin showed that two pyrolysis products which were indole and methylindole originating from the enzyme (contents 12 to 44%), in addition to eight pyrolysis products originating from syringyl (S) and guaiacyl (G) structure of lignin. Furthermore, palmitic acid was also detected in the residual lignin (contents 0.11 to 0.28%). The residual lignin was subjected to further purification by a cellobiose treatment method, and the quantity of enzyme present in the residual lignin was found to decrease after the treatment. Residual lignin in PH-soda-AQ pulp exhibited a higher S/G ratio (0.86 to 0.98) than that in soda-AQ pulp (0.76 to 0.97). This study showed that the contents of lignin (19 to 44%) and enzyme in enzymatically isolated lignin can be estimated by the Py-GC/MS method.

“…The OPEFB contain chemical blocks of cellulose, hemicellulose and lignocellulose, while its present utilization as a biofuels, fertilizer, and compost production [1] [2], however its utilization can lead to emission resulting in organ damages and impact on the environmental systems. Besides, OPEFB been reported to possess many distinct advantages, some of them are: pulp [3], feedstuff [4], carbon briquette [5], activated carbon [6], and fillers [7]. The OPEFB are also used as foods [8], oleo chemicals [9], and soap [10].…”

In a future carbon-constrained global economy, the use of fossil fuels will be restricted. Biomass resources will be increased demand for renewable products. Oil Palm Empty Fruit Bunches (OPEFB) can be used as lignocellulose feedstock. The production of biofuels from lignocellulose feedstock can be achieved through biochemical or thermo-chemical routes. OPEFB contain chemical blocks of cellulose, hemicellulose and lignocellulose. Due to these substances, OPEFB can be converted into bio-products and chemical. Special attention to biorefinery approach that is present at relatively high potential in bio-products such as polymers, nutraceuticals, chemical building blocks, biofuels, and bioenergy. Different utilization types were considered and reviewed, and the most common and efficient process were discussed. In general, there is no single product which could be considered a solution to the utilization of managing OPEFB -in this review a number of product are more economic, effective and environmentally friendly.
