Summary: This study evaluated the quality and quantity of spearmint essential oil and found that lower pH in the hydro-distillation process led to higher yield, while adding 1% and 1.5% NaCl concentrations increased the oil yield. Although the yield was reduced in microwave-assisted hydro-distillation, carvone content increased by 12.7% and limonene content decreased by 42.3% within 120 minutes. Solvent extraction followed by rotary evaporator yielded the best quality spearmint oil.

Summary: The feasibility of biorefinery highly depends on the early design of the most suitable pathway for converting feedstock into value-added products. Pretreatment, as a critical stage in biorefinery design, greatly influences subsequent reaction, separation, and purification processes. However, previous pretreatment analyses have mainly focused on preserving and utilizing six-carbon sugars, leaving out hemicellulose and lignin. This study provides a systematic evaluation of pretreatment efficacy for the removal of lignocellulosic fractions based on operational, economic, environmental, and social indicators. The results demonstrate that dilute acid pretreatment is the most effective for cellulose isolation and hemicellulose removal, while the kraft process is the best method for lignin removal and its future utilization in biorefineries. This research contributes to the understanding of pretreatment efficacy in biorefinery design at an early feasibility stage, with consideration of sustainability aspects.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
