Hemicelluloses and Lignin in Biorefineries

Jean-Luc Wertz holds degrees in Chemical Civil Engineering and in Economic Science from Catholic University of Louvain, as well as a PhD from the same university in Applied Science, specializing in polymer chemistry. He has held various international positions in R&D, including Spontex, where he was worldwide director of R&D. He holds several patents related to various products. Jean-Luc Wertz is now Project Manager in biomass valorization at ValBiom and has worked for more than 8 years on lignocellulosic biorefineries and biobased products. He also wrote two books in 2010 and 2013. After completing a Master's degree in chemical sciences, Séverine Coppée got a PhD degree in Material Sciences at the University of Mons, Belgium. She then worked as a postdoctoral fellow in the field of organic photovoltaics in the US first and then for Materia Nova research center, Belgium. Since 2014, Dr. Coppée has been a project manager for GreenWin competitiveness cluster in Wallonia and is supporting the cluster members with building up biobased chemistry research projects through various funding opportunities, particularly in the framework of the Bio-Based Industries Consortium (BIC) of which GreenWin is an effective member. She is also an LCA advisor involved in the Life Cycle in Practice European project (co-funded by the LIFE + Environment Policy and Governance Programme of the EU) of which GreenWin is a partner. The LCiP project helps SMEs in France, Belgium, Portugal and Spain to reduce the environmental impacts of their products and services across the entire life cycle.Magali Deleu holds a Master's degree in Chemical Engineering and Bioindustries from Gembloux Agro-Bio Tech (University of Liege), as well as a PhD degree from the same University in Agricultural Sciences and Biological Engineering. After a postdoc at Lund University in Sweden, Dr. Deleu got a permanent position since 2003 as Research Associate and since 2014 as Senior Research Associate at Belgium National Funds for Scientific Research (F.R.S. - F.N.R.S.) at Gembloux Agro-Bio Tech in the Laboratory of Molecular Biophysics at Interfaces. She is engaged in research and education concerning the physico-chemical and membrane properties of surfactants from biomass. Her main research interest is to explore the molecular mechanisms involved in the perception of structurally different amphiphilic molecules by biological membranes. She has published about seventy papers on this topic.Aurore Richel holds a degree in Chemical Sciences and PhD in Chemistry from University of Liege. Prof. Richel is currently Professor and Head of the Laboratory of Biological and Industrial Chemistry at the University of Liege. She is engaged in research and education in the fields of biological chemistry, biorefining and industrial technologies. Prof. Richel is involved in numerous projects and industrial collaborations, specializing in the following areas: optimized use of vegetal biomass and waste for bioproducts and biofuels and development of new methodologies with low environmental footprints. She has published dozens publications on this topic.

"The authors, internationally recognized experts in their field, provide a very valuable piece of work for those who want to discover the bioeconomy concept and how it is translated today when it comes to the valorization of lignocellulosic biomass. This book provides the scientific base needed to address the biorefinery concept. easily accessible to college students, and it also provides relevant references that will allow the reader to go deeper into the concepts."—Florent Allais, AgroParisTech, France"The table of contents is well organized, enabling the readers and/or the users to easily find the information they are looking for, but also to decide the chapters they want to read or share. I really want to have the book for my organization because it is a priority area of interest for us and also a fast-moving area."— Philippe Mengal, Bio-Based Industries, Brussels, Belgium"This is a very interesting book focusing on modern biorefineries. The reader will find precious information about bioeconomy and the bio-based programs developed in the USA and in Europe, but also about the molecular mechanism and the processes underlying biomass transformation. This lavishly illustrated book is a wonderful window on the world of hemicellulose and lignin biorefineries."—Dimitri Gilis, Université Libre de Bruxelles, Belgium"Bio-economy through bio-refinery science and technology is going to sound the death knell for the conventional petroleum-based industry. Undoubtedly this book highlights the remarkable and unique benefits offered by bio-refinery of lignocelluloses and lignin."—Philippe Dubois, University of Mons, Belgium"Hemicelluloses and lignin are the promising feedstocks for a sustainable bioeconomy. This book gives a very detailed overview of the state of play of the synthesis, structure, degradation and possible valorization, and will be useful for students, academic and industrial scientists as well as other professionals who would like to know more about these feedstocks."— Dirk Carrez, Bio-Based Industries, Brussels, Belgium
