Hybrid Lignocellulosic Biomass as Energy Feedstock: A Mini Review

Lignocellulosic biomass, composed primarily of cellulose (35–50%), hemicellulose (20–35%), and lignin (15–30%), has emerged as a promising renewable resource for sustainable energy production due to its abundance, renewability, and capacity to reduce greenhouse gas emissions. This study presents a comprehensive evaluation of lignocellulosic biomass composition and examines the potential of hybrid feedstocks combinations of different biomass types to enhance conversion efficiency and product yield. Key biomass conversion technologies are reviewed, including thermochemical processes (pyrolysis, gasification, and combustion), biochemical processes (anaerobic digestion and fermentation), and chemical depolymerization routes. Integrating hybrid lignocellulosic biomass with these technologies can improve energy recovery, increase process flexibility, and support more effective utilization of regionally available feedstocks. This work underscores the critical role of hybrid lignocellulosic biomass in advancing clean energy solutions and contributing to global sustainability targets.
