“…Sugars (e.g., glucose, xylose, cellobiose) and organic acids (e.g., acetic acid) in liquid fraction from DES pretreatment of EFB were quantified by HPLC (Waters model Alliance 2690, USA) equipped with Aminex HPX-87H Column (7.8 mm × 300 mm, BioRad, USA) and reflective index (RI) detector. The column temperature was set at 60 °C and the 0.005 mol L −1 sulfuric acid was used as a mobile phase at a flow rate of 0.6 mL min −1 53 – 55 .…”

This research aimed to study on nanocellulose production from palm bunch using process design and cost analysis. Choline chloride based deep eutectic solvent pretreatment was selected for high-purity cellulose separation at mild condition, followed by nano-fibrillation using mechanical treatment. Three types of choline chloride-based deep eutectic solvents employing different hydrogen-bond donors (HBDs) namely lactic acid, 1,3-butanediol and oxalic acid were studied. The optimal cellulose extraction condition was choline chloride/lactic acid (ChLa80C) pretreatment of palm empty bunch at 80 °C followed by bleaching yielding 94.96%w/w cellulose content in product. Size reduction using ultrasonication and high-pressure homogenization produced nanocellulose at 67.12%w/w based on cellulose in raw material. Different morphologies of nanocellulose were tunable in the forms of nanocrystals, nano-rods and nanofibers by using dissimilar deep eutectic solvents. This work offered a sustainable and environmentally friendly process as well as provided analysis of DES pretreatment and overview operating cost for nanocellulose production. Application of nanocellulose for the fabrication of highly functional and biodegradable material for nanomedicine, electronic, optical, and micromechanical devices is achievable in the near future.

“…However, other crops are also prominent, such as wheat, cassava, rice, banana, and oil palm. Processing these crops generates large amounts of solid residues, including in‐field or agricultural residues (straw, leaves, and foliage) and agro‐industrial processing residues (bagasse, bunches, and shells) with diverse composition and volume (Table ) …”

South America is a pivotal supplier of agricultural commodities for a growing world population. This large-scale production generates a substantial amount of lignocellulosic residue. Inadequate disposal of this material can lead to putrefaction and leaching, and can attract insects and rodents. Solid residues can be treated by incineration or composting -both causing greenhouse gas emissions. Biotransformation of lignocellulosic residues into valuable products has been proposed as a more sophisticated alternative to burning. However, pretreatment steps are necessary to obtain fermentable sugars for biological or thermochemical transformation into value-added products. In this review, we noted trends in lignocellulosic biomass generation and potential uses, with special attention to the procedures necessary for the generation of fermented products and bio-oil. This survey pointed out that sugarcane bagasse, cereal straws, bananas, and oil-palm biomass can generate about 900 million tonnes of biomass by 2025. Based on production data from several researchers it was estimated that these raw materials have the potential for annual production of more than 550 million tonnes of fermentable sugars (i.e., glucose and xylose), 670 million tonnes of bio-oil, or 4000 TWh of thermal energy. We describe procedures and strategies for the conversion of these residues to produce higher value-added biomolecules and to promote more sustainable application of lignocellulosic biomass

“…However, the use of homogeneous acid catalysts has drawbacks, including the corrosive nature of acid, reusability of the catalyst, product separation, and the need for waste and water treatment. As an issue of concern, alternative heterogeneous solid acids have been recently investigated as catalysts for the separation of lignocellulosic materials, with the key advantage of a less side-chain degradation of the derived products and easy recovery. , Heterogeneous acid catalysts, for example, H 3 PO 4 –activated carbons (AC–H 3 PO 4 ) and a series of SO 4 2– /M x O y /Fe 3 O 4 /WO 3 solid acid catalysts, can be applied for various lignocellulosic applications, including biomass fractionation, cellulose hydrolysis, , lignin depolymerization, and torrefaction . Microwave irradiation generates heating by the direct coupling of microwave energy with the molecules that are present in the reaction mixture as opposed to a slow and inefficient energy transfer when using conventional heating. − The microwave-accelerated CF process has been reported for rice straw, which showed advantages in product yield and selectivity compared to the conventional CF process, suggesting a potent alternative for developing a less energy-intensive process for the efficient fractionation of lignocellulosic materials.…”

Organosolv fractionation is a promising approach for the separation of lignocellulosic components in integrated biorefineries where each component can be fully valorized into valuable platform chemicals and biofuels. In this study, microwaveaccelerated organosolv fractionation was developed for the modification of lignocellulosic fractionation of rice husk. The fractionation condition was optimized for 1 h with the microwave irradiation at 300 W using a ternary solvent mixture composed of 24%:32%:44% water/ethanol/methyl isobutyl ketone. The effects of mineral acids (HCl, H 3 PO 4 , and H 2 SO 4 ) and heterogeneous acid promoters (HCl, H 3 PO 4 , and H 2 SO 4 impregnated over activated carbon) on the efficiency and selectivity of product yields (i.e., glucan, hemicellulose-derived products, and lignin) were also investigated. It was found that the use of H 3 PO 4 −activated carbon as the promoter showed superior performance on the fractionation of rice husk components, resulting in 88.8% recovery of cellulose, with 63.8% purity in the solid phase, whereas the recovery of hemicellulose (66.4%) with the lowest formation of furan and 5-hydroxymethyl furfural and lignin (81.0%) without sugar cross-contamination was obtained in the aqueous ethanol phase and organic phase, respectively. In addition, the morphology structure of fractionated rice husk presented 2.6-fold higher surface area (5.4 m 2 /g) of cellulose-enriched fraction in comparison with the native rice husk (2.1 m 2 /g), indicating the improvement of enzyme accessibility. Besides, the chemical changes of isolated lignin were also investigated by Fourier-transform infrared spectroscopy. This work gives pieces of information into the efficiencies of the microwave strategy as a climate neighborly elective fractionation method for this serious starting material in the biotreatment facility business.
