Abstract
This study optimized microwave-assisted alkaline pretreatment for enhancing sugar recovery from sugarcane bagasse. Bagasse was dried, ground, and sieved to a uniform particle size before undergoing pretreatment with sodium hydroxide (NaOH). The effects of microwave power, duration, and NaOH concentration were investigated. Optimal conditions were identified as 800 W microwave power, 8% (w/v) NaOH, and a 2-minute duration (18.69 ± 0.05 g/L). An NaOH concentration of 8% (w/v) achieved high sugar recovery while minimizing chemical use, highlighting the balance between efficiency and sustainability. These findings provide a foundation for improving lignocellulosic biomass pretreatment for biofuel and biochemical production.
