The Effects of Pretreatment with Different Concentrations of Sodium Hydroxide on Paddy Straw for Biogas Production
Paddy straw is an abundant agricultural residue with high potential for renewable energy generation through anaerobic digestion; however, its lignocellulosic structure limits biodegradability and biogas yield. This study evaluates the effect of sodium hydroxide (NaOH) pretreatment on biogas production from fresh and dr...
