![]() The industrial potential of lignin-derived products such as aromatics, biopolymers, biofuels and agrochemicals are also outlined. In this review, the recent advances in the lignin extraction and depolymerization methods that may help in achieving the cost-economics of the bioprocess are summarized and compared. The components of lignocellulosic biomass might be totally transformed into a variety of value-added products with the improvements in bioprocess techniques that valorize lignin. A deeper understanding of lignin characteristics and factors governing the biomass conversion into valuable products can support improved biomass consumption. The successful valorization of lignin for the production of bio-based platform chemicals and fuels has been the subject of intensive investigation. ![]() The present review provides an in-depth knowledge on the journey of lignin from being considered a roadblock to a bridge connecting diverse industries with widescale applications. Lignin, a natural biopolymer has over the years gained much importance as a high value material with commercial importance. Lignocellulosic biomass constituted by cellulose, hemicellulose and lignin is an abundantly available natural bioresource.
