The book "Production of Biofuels and Chemicals from Lignin" offers comprehensive insights into the latest developments and research on lignin production, as well as biological, thermal, and chemical conversion methods. It covers fundamental topics in lignin chemistry, including the properties, analysis, and characterization of lignin, as well as the mechanisms of depolymerization. Additionally, it discusses methods for the enzymatic, fungal, and bacterial degradation of lignin. Practical aspects such as technologies for recovering lignin and ultra-pure lignin, the production of activated carbon and carbon fibers, and the biological conversion of lignin for chemical production are also addressed. The book concludes with a case study on the practical production of polyurethane foams using lignin. It serves as a valuable resource for students, researchers, academics, and professionals in the fields of biochemistry and energy.
