Dr. Scott Chang is a Professor in the Department of Renewable Resources at the University of Alberta. He received his education from the University of British Columbia (Ph.D. in forest soils), the Chinese Academy of Sciences (M.Sc. in soil ecology) and Zhejiang Agricultural University (B.Sc. in soil science and agricultural chemistry).
His main research interests are in forest soils, biogeochemistry, and the application of soil science in land reclamation, agriculture, forestry, and global change. In his Future Energy Systems project, he is developing novel materials from agricultural/forestry waste products using three approaches: production of biochars through pyrolysis in a muffle furnace or in a microwave, and production of hydrochars through hydrothermal carbonization under high temperature and pressure. The feedstock type and production conditions for biochars and hydrochars are being optimized to produce novel materials that are effective for the removal of toxic metals from wastewater. The effectiveness and mechanisms of biochars/hydrochars for wastewater treatment are being studied using adsorption/desorption experiments. The stability of metals adsorbed on to biochars/hydrochars are being studied and the techniques are being scaled up for potential industrial applications (e.g., in constructed wetlands).
Dr. Chang is currently a regional editor for Biology and Fertility of Soils, and an editorial board member for Pedosphere and Forests. He served as Chair of the Soil Fertility and Plant Nutrition Commission of the International Union of Soil Science, Chair for the Forest, Range and Wildland Soils Division of the Soil Science Society of America (SSSA), and Chair of the Alberta Soil Science Workshop. He was an editor for special issues for the Canadian Journal of Soil Science and an associate editor/guest editor for Journal of Environmental Quality, Environmental Science and Pollution Research, Forests, Forest Ecology and Management, and the Canadian Journal of Soil Science. He is a Fellow of the Soil Science Society of America (2016), American Society of Agronomy (2016), and the Canadian Society of Soil Science (2018).
