This book covers lignin, a renewable source of carbonaceous material derived from biomass, which is a subject of research, development and innovation in both academia and industry.

From lignin we can obtain chemicals (e.g., aromatics, phenols), materials (e.g., fibres, engineered plastics, modified polymers), specialties (e.g., additives as antioxidant), among other products in diverse levels of technology readiness. However, there are challenges to overcome in terms of chemical structure, industrial yields of conversion processes, and the quality of raw material in order to reach the best uses and applications according to the sustainability vision for products and processes. This book deals with the main biochemical pathways of synthesis; advanced analytical techniques; extraction strategies; chemical, biochemical, biological, and physical processing for chemicals and materials; circularity and sustainability aspects for actual and future production chains, allied to life cycle assessment and industrial ecology.

He is author, co-author and editor of articles, books and chapters, highlighting the books Analytical Techniques and Methods for Biomass (Springer Nature, 2016), Biomass and Green Chemistry - Building a Renewable Pathway (Springer Nature, 2018), Analytical Chemistry Applied to Emerging Pollutants (Springer Nature, 2018), Sustainable Agrochemistry - A Compendium of Technologies (Springer Nature, 2019), Treatment of Agroindustrial Biomass Residues (Springer Nature, 2020), Applications of Analytical Chemistry in Industry (Springer Nature, 2023); and Analysis of Chemical Residues in Agriculture (Elsevier, 2021) and Renewable Carbon - Science, Technology and Sustainability (Elsevier, 2022). He is past president of the ACS Brazil Chapter of the American Chemical Society. He is the leader of the Embrapa/CNPq research group in renewable chemistry. He is the winner of two editions of the Kurt Politzer Prize of the Brazilian Chemical Industry Association (new enterprise category 2008 and researcher 2011 category). He is a member of the Carbon Pricing Leadership Coalition of the World Bank. He serves as professor of the graduate program in Environmental Engineering at Federal University of Ouro Preto, Brazil, and of the graduate programme in Biofuels (Federal University of Uberlândia, Brazil); he serves also as collaborator of the graduate program in Chemical and Biochemical Process Engineering (Federal University of Rio de Janeiro, Brazil). Recently, Dr. Vaz Jr. received the Talents 2024 award from the Federal Chemistry Council (Brazil) as winner of the Industrial Chemistry/Technological Chemistry category.
