Abstract
Optimization of bioethanol production from lignocellulosic waste has garnered significant attention as a sustainable energy solution aligned with engineering practices existing up to 2015. This manuscript reviews pretreatment and hydrolysis techniques, fermentation strategies, and process integration approaches that were well established by 2015, then examines two representative case studies demonstrating practical yields. A laboratory-scale methodology is presented, detailing feedstock characterization, dilute acid pretreatment, enzymatic saccharification, and yeast fermentation. Results indicate that under optimized conditions, ethanol yields of up to 75 % of theoretical can be achieved, corroborating findings from prior studies. The conclusion synthesizes key engineering considerations for scale-up and highlights research gaps in process intensification and cost reduction. Ten foundational references published through 2015 are provided.
