Paragraph starter

The conversion of lignocellulosic biomass into bioethanol represents a significant avenue for renewable energy generation, as highlighted by Igwebuike et al. (2024). This second-generation feedstock offers a sustainable alternative to fossil fuels and first-generation biofuels by avoiding competition with food crops. However, the inherent recalcitrance of lignocellulosic materials necessitates complex pretreatment and hydrolysis steps, often leading to challenges such as inhibitory byproduct formation and high production costs, which impede large-scale implementation.
