Biomaterials and Bioethanol from Lignocelluloses

Biomaterials webinar.png

An industrial production of biomaterials and bioethanol from lignocelluloses such as corn cob and other cereal straws by a combination of hydrothermal pre-treatment and alkali post-treatment based on a biorefinery scenario have been performed at Shandong Longlive Bio-Technology Co., Ltd, since 2010 in China, in which 30 thousands tonnes of bioethanol, 10 thousands tonnes of xylo-oligosaccharides and 18 thousands tonnes of xylitol with a purity of more than 97%, 300 tonnes of arabiose with a purity of more than 98.5%, and 20 thousands tonnes of lignin with a purity of more than 94% have been produced from 200 thousands of corn cob per year. Lignin recovered as a by-product from the bioethanol production, was used to produce lignin-phenol-formaldehyde adhesives with a yield of about 50 thousand tons per year for commercial production of biocomposite boards for construction and furniture in China today. Another industrial utilization of the by-products of lignins from the bioethanol production and papermaking as rubbish bags in shanghai city and agricultural mulching films on farms will be reported.

Who should watch:

Professor Run-Cang Sun, ligniocellulosic chemist, graduated from chemistry department, North-western University, Xian, China in 1982. Then he worked at North-western Forestry College, The BioComposites Centre, University of Wales, UK, State Key Laboratory of Pulp and Paper Engineering as a director, South China University of Technology, Guangzhou, China, Beijing Key Laboratory of Lignocellulosic Chemistry as a director. He was also a Dean at the College of Materials Science and Technology between 2011 and 2015, Beijing Forestry University, Beijing, China. Since March 2019, Prof. Sun has being working at Liaoning Key Laboratory of Lignocellulose Chemistry and BioMaterials, Dalian Polytechnic University, Dalian, China. He has focused on the fractional isolation, structural characterization, and chemical modification of hemicelluloses, lignin, and cellulose from lignocellulose for biomaterials, biofuels, and chemicals. He has published 872 SCI papers in peer reviewed international journals in English, which have been cited over 41,000 citations (his Google Scholar h-index of 100). He edited a book under the title of “Cereal Straw as a Resource for Sustainable Biomaterials and Biofuels: Chemistry, Extractives, Lignins, Hemicelluloses and Cellulose” 2009, Elsevier, London. As invited author, he also authored 35 book chapters regarding utilization of lignocelluloses (in English) such as Encyclopedia of Separation Science (2000 vol. 6, pp. 4568-4574, Academic Press, London). He was granted 135 patents for inventions. He is the recipient of the ACS Cell Division Anselme Payen Award 2020. Prof. Sun is a Fellow of The Royal Society of Chemistry, UK in 2003 and an Editor-in-Chief of “Industrial Crops and Products”,  Associate Editor of “Carbohydrate Polymers”, “BioResources” Journal, “Journal of Biobased Materials and Bioenergy”, He is also a member of editorial board in “Chemsuschem”,“Journal of Agricultural and Food Chemistry”, “International Journal of Cellulose Chemistry and Technology”, “The Scientific World Journal”,Bioresources and Bioprocessing,EcoMat etc.
