“…For these purposes, the AF2 clone of Populus x euramericana was evaluated as a raw material for hemicellulose extraction using CAE, both with and without ultrasound assistance. The process included modeling and optimization through multiple regression, a widely employed approach for optimizing biomass and waste stream valorization [35,36]. The aim was to obtain a high-value liquid fraction and energy from the resulting solid residue, within the context of comprehensive utilization (biorefining).…”

Alkaline pretreatments are considered highly effective for the separation of the different components of lignocellulosic biomass. However, cold alkaline extraction (CAE) exhibits minimal modification/degradation of hemicellulosic fraction and successfully accomplishes efficient delignification. In this research, the fast-growing clone AF2 of Populus x euramericana wood was utilized as the raw material and subjected to ultrasound-assisted CAE. The objective of incorporating ultrasound into cold alkaline extraction is to increase the yield of a hemicellulosic-rich liquid phase that can be used to produce high-value products such as furfural or xylitol. Simultaneously, it aims to obtain a solid phase with a higher calorific value compared to the raw material. The results, obtained from a central composite factorial design, demonstrated that the CAE process for 90 min at a sodium hydroxide concentration of 100 g L−1, a temperature of 30 °C, and with ultrasound assistance maximized hemicellulose extraction in the liquid phase (60.8% was extracted) and improved the heating value of solid phase.
