Converting various biomass wastes into biochar and hydrocar has provided a value-added pathway for waste disposal and utilization. However, due to the complex nature of environmental matrices and the cooccurrence of contaminates, there is increasing interest in developing biochars/hydrochars capable of multiple functions and applications. This will allow more efficient and cost-effective dealings with agricultural and environmental solutions. This presentation will discuss different approaches to improving Biochar's fertilizer value to increase crop production, disease control, mitigate greenhouse gas emissions, improve soil health, use for water treatment, resource recovery, and catalytic functions. 

The speakers
Dr. Jim Wang is a professor of environmental soil chemistry and the A. George & Mildred G. Caldwell Professor at Louisiana State University, USA. He earned a B.S. from the Northwestern College of Agriculture, China, and an M.S. and Ph.D. from Iowa State University, USA. Prof. Wang's research program focuses on the characterization of interactions between nutrients/pollutants and soil constituents and organic carbon transformation. His recent projects work on the development of functionalized biochars for improved agricultural and environmental applications, and he has authored and co-authored more than 140 referred journal articles. Prof. Wang serves on the editorial board of Biochar published by Nature Springer. He is a Fellow of both the American Society of Agronomy and the Soil Science Society of America. 

Dr. Changyoon Jeong received his Ph.D. in the field of environmental chemistry from the University of Nottingham in the U.K. Currently, he is an associate professor at the Louisiana State University Agricultural Center. He is also an adjunct professor in the Department of Biological Science, College of Arts and Sciences, Louisiana State University at Shreveport, LA. Research focuses on the impact of biochar/hydrochar application in water quality, greenhouse gas emission, and crop production. He conducted several biochar projects funded by the USDA, NRCS, and Louisiana commodity board. Several scientific papers are published in peer-reviewed journals such as Environmental Pollution, Energies, Science of the Total Environment, Journal of Environmental Quality, etc. Dr. Jeong is a member of Science Advisory in the Louisiana Climate Initiatives Task Force (CITF) organized by the Louisiana Governor's office.

Dr. Luca Fiori is associate professor of Chemical Engineering at UniTN, where he is the leader of the Green Processes Engineering Lab, active in the Circular Bioeconomy. His research focuses on the upgrading of biomass, agro-industrial and urban waste to energy and added-value materials and compounds. The expertise on technologies regards supercritical CO2 extraction and hydrothermal processes - hydrothermal  carbonization in particular – also coupled with anaerobic digestion and composting, in view of a holistic valorization of biomass constituents. He has authored and co-authored more than 110 referred journal articles (H-index: 47). He is a member of the Scientific Advisory Board of Waste and Biomass Valorization by Springer, he serves on the editorial board of Applied Science by MDPI, and he is evaluator of research proposals in national, international, and European (Horizon Europe) calls.
