N2 - With increasing population worldwide and the consumption of greenhouse gases (GHGs) emitting limited fossil fuel resources, the indispensable need of seeking sustainable energy sources and conversion methods have been realized that can offer possible alternative ways to substantially minimize biomass wastes and even pre-treatments assisted biorefinery systems to convert those wastes into biofuels and other bioproducts. Considerable attention, therefore, has been given to the generation of biofuels from lignocellulosic biomass including the agricultural wastes. Biochemical and biological methods for converting lignocellulosic biomass to biofuels are challenging because of their unreactive nature, and pre-treatments are the key for their successful and efficient conversions. This review explored, compared, and highlighted the significance of multi-stage pre-treatment over the single-step biorefinery systems for biofuels production from different sources. The multi-stage methods have exhibited to demand less energy consumption and reaction time, to enhance productivity of lignocellulose deconstruction. However, optimized and engineered multi-stage pre-treatment methods for multi-product biorefinery from specific feedstocks have not been fully investigated yet. The authors present the future research direction for potential industrial application of multi-stage pre-treatments with key technical considerations as well.
