Summary: This study employed lignin blockers, including non-catalytic protein and surfactants, to enhance the enzymatic digestibility of pretreated poplars. Among them, Tween 80 showed the most significant improvement, increasing glucose yield and reducing the required enzyme loading. Quartz crystal microbalance analysis revealed that Tween 80 had a higher binding rate on lignin surfaces compared to enzymes and significantly reduced the enzyme-lignin binding capacity and rate. These findings contribute to understanding the mechanism of surfactant promotion in enzymatic hydrolysis.

Summary: In this study, poplar flour and walnut shell flour were used as biomass precursors to prepare biochars for the activation of peroxymonosulfate. The biochars derived from poplar flour showed better performance in the adsorption and degradation of diclofenac compared to those derived from walnut shell flour. The adsorption and catalytic performance of both biochars improved with the increase of pyrolysis temperature, and the biochar derived from poplar flour at 1000°C exhibited stronger capability and adaptability to complex water environment than the one derived from walnut shell flour at 1000°C.

Summary: The economically viable alternative of agricultural by-product bioethanol provides a sustainable solution for expanding the use of renewable energy, ensuring greater energy supply security, and reducing environmental impacts. Improving the efficiency of existing processes is crucial to reduce costs, industrial waste, and carbon footprint. Ionic liquids (ILs) have shown promise in achieving cleaner processes and efficient dissolution and fractionation of lignocellulose for biofuel production. This review analyzes recent advances in biofuel production from lignocellulosic biomass using ILs as pretreatment and highlights cost optimization techniques for robust conversion processes.

Summary: Ethanol biofuel derived from lignocellulosic biomass can reduce reliance on fossil fuels, lower carbon emissions, and improve energy efficiency. Various lignocellulosic materials and weed biomass have been explored as potential alternative energy sources. Vietnamosasa pusilla, a weed belonging to the Poaceae family, has high glucan content and can be efficiently converted into fermentable glucose and cellulosic ethanol without detoxification. These findings suggest that V. pusilla biomass can be utilized for biofuel production in sugar-based biorefineries.

Summary: This study aimed to comprehend the extraction process and characteristics of natural fibers extracted from Borassus flabellifer L. leaf. The fibers were treated with sodium hydroxide solution, which improved their cellulose content, tensile strength, and density, while reducing the content of hemicellulose, lignin, and wax. XRD and FTIR analysis confirmed that the alkali treatment improved the crystallinity and surface condition of the fibers.

Summary: The effects of switchgrass particle sizes on the effectiveness of H2SO4 and NaOH pretreatments were investigated. Increasing particle size led to higher contents of glucan, xylan, and lignin in raw switchgrass. SEM images and FTIR spectra showed no visible variations in microstructures and chemical bonds among different particle sizes under the same pretreatment conditions. The optimal ethanol conversion performance depends on the interaction between the pretreatment method and biomass particle size.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
