“…For ULC‐30 sample, changes in the compact rigid structure to a distorted loosened structure with fibrils or microfibril were observed as a result of ultrasonic treatment (Figure b). In contrast, Abdullah, Nazir, Raza, Wahjoedi, and Yussof () reported that the ultrasonic‐treated fibres showed the punctures and pores on the surface. The discrepancy in the surface morphology between our study and that of Abdullah et al () may be attributed to the different pretreatment methods of cellulose.…”

The discrepancy in the surface morphology between our study and that of Abdullah et al () may be attributed to the different pretreatment methods of cellulose. The granulometric distribution was significantly different between the untreated samples, with a mean diameter (D 4, 3) of 60.988 ± 0.927 μm, and the ULC‐30 samples, with a mean diameter of 27.804 ± 0.128 μm, respectively (Figure c).…”

The effect of ultrasonic treatment was evaluated to develop an efficient preparation method of cellulose with controllable molecular weight (Mw) and preferable functional properties. Our results showed that the physical approach could prominently reduce the mean Mw of cellulose from 68.07 to 6.82 KDa via 30‐hr ultrasonic treatment. The morphology and structure of the samples were characterized using Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscope (SEM), and laser diffraction, indicating a slight change in structure and notable modification in morphology caused by ultrasonic treatment. Interestingly, the ultrasonic‐treated cellulose exhibited much better physicochemical properties. For example, with a 30‐hr ultrasonic treatment, the cholesterol‐binding capacities of cellulose were increased about 2.42‐fold at pH 7.0 and 1.96‐fold at pH 2.0. The findings demonstrated that cellulose treated by ultrasonic processing could have a great potential for applications in the biomedical and food industries. Practical applications As a major source of insoluble fiber, cellulose has already been recommended for its possible benefits to human health, leading to numerous efforts for its applications in food industry and biomedical engineering. In this work, we successfully controlled Wm of cellulose via ultrasonic treatment, and the ultrasonic‐treated cellulose exhibited improved functional and physicochemical properties. The positive effect of ultrasound may be useful for functional modification and utilization of cellulose.

Oil palm empty fruit bunch (EFB) has a big potential in biocomposite production. The porous surface of EFB is advantageous for physical interlocking with polymer in composite fabrication. The objective of this study is to determine the properties of biocomposite prepared from steam-treated EFB with polypropylene (PP). The EFB was treated using steam at 120 °C for 30 min and 60 min in an autoclave. The biocomposite was prepared from EFB and PP at different fiber contents (10 and 30 wt.%). The Steam-30 EFB partially removed silica bodies and other impurities without damaging the surface of the EFB. The thermal stability improved from 276 to 283 °C. The Steam-30/PP biocomposite had the highest tensile strength at 10 and 30 wt.% EFB contents with the increments of 23.9 and 23.8%, respectively, compared to that of the untreated EFB/PP biocomposite. The Steam-30/PP biocomposite containing 30 wt.% of EFB had a low water absorption of 5.6% compared to that of the untreated EFB/PP biocomposite at 7.2%. In conclusion, steam treatment improved the characteristics of EFB and increased the compatibility between the fiber and polymer.

“…Pese a que los estudios relativos al desarrollo de materiales elaborados con residuos agroindustriales de palma aceitera crecen a nivel mundial, gran parte de ellos han sido realizados únicamente con residuos originarios del sudeste asiático, India y África occidental (Abdullah, Nazir, Raza, Wahjoedi, & Yussof, 2016;Ching et al, 2014;Rozman, Lai, Ismail, & Mohd Ishak, 2000;Rozman et al, 1999;Rozman, Saad, & Ishak, 2002;Shinoj, Visvanathan, Panigrahi, & Kochubabu, 2011;Wirjosentono, Guritno, & Ismail, 2004). Por otra parte, la microestructura y propiedades de las fibras lignocelulósicas dependen en gran medida de la variedad cultivada así como también de factores edafoclimáticos de la plantación y de la zona geográfica (Mohit & Arul Mozhi Selvan, 2018), por lo que las investigaciones llevadas a cabo con residuos procedentes de otras zonas geográficas, no son completamente extrapolables a la realidad latinoamericana.…”

La creciente actividad industrial de extracción del aceite de palma africana (Elaeis guineensis Jacq.) en el Ecuador ha provocado la generación de elevados volúmenes de residuos de raquis, los cuales actualmente son dispuestos a cielo abierto en las plantaciones de este vegetal. Por tal motivo, el objetivo de la propuesta doctoral es obtener materiales compuestos a partir de matrices termoplásticas y desechos lignocelulósicos derivados de la producción industrial de aceite de palma africana en Ecuador. Como etapa inicial se ha realizado la recolección y molienda de los desechos de fibra. Una vez determinado el comportamiento granulométrico de la fibra molida se procedió a la caracterización de la composición fisicoquímica y al análisis por espectrometría infrarroja con transformadas de Fourier. Los resultados muestran comportamiento granulométrico independiente de la ubicación de la fibra en el raquis y mayor porcentaje de retenido a una abertura de malla de 0,42 mm. La espectrofotometría infrarroja evidencia la presencia de bandas características de la celulosa, hemicelulosa y lignina de similar intensidad en cualquier fracción peduncular del residuo.
