Pre-treatment process contributes towards overall cost of biomass conversion and thereof the design of lignocellulosic pretreatment stage with a biorefinery/bioproducts approach could be highly feasible. We had developed a sequential chemical and enzymatic delignification process for lignocellulosic biomass, and the biorefinery prospects are highlighted through this work. Hydrogen peroxide pre-treatment could solubilize more than 50 % of lignin into process effluent ��?Black liquor��?, from which lignin could be recovered by acid precipitation and further purified. Lignin itself is a significant bio-product with several industrial applications. Industrial products such as vanillin, nanocomposites, etc could be further developed from the recovered lignin. Besides, the photocatalytic treatment of ��?Black liquor��? generates intermediates which could be developed into valuable products with industrial applications. For enzymatic delignification, instead of depending on commercial enzymes, solid state fermentation techniques could be applied on lignocellulosic residues for ligninases production. Bulk level production of ligninases along with other enzymes could also meet the industrial and nanobiotech applications or demands. Biomass process residues could be finally converted into biochar with significant environmental and agricultural applications. Integration of comprehensive biorefinery concept in the lignocellulosic pre-treatment stage could thus yield multiple lignin based bio-products along with sustainable energy generation. Biorefineries across the nations could strengthen the global bioeconomy as well as meet the bioenergy goals.
