Evaluate technological advancements, processing bottlenecks, and industrial integration pathways for producing second-generation bioethanol from lignocellulosic biomass.
Assessed conversion steps including biomass pretreatment, enzymatic hydrolysis, and microbial fermentation across emerging literature.
Evaluated Technology Readiness Levels (TRL), co-product generation strategies, and whole-facility techno-economic integration models.
Optimized pretreatment and hydrolysis configurations achieve fermentable sugar recoveries between 0.70 and 0.90 g sugars/g biomass.
Advanced pretreatment technologies have achieved Technology Readiness Levels (TRL) of 8–9, demonstrating near-commercial viability.
Key commercialization hurdles persist regarding microbial inhibitor formation, high enzyme costs, and scale-up limitations, necessitating integrated biorefinery approaches.
