He is the professor at Central South University and the academician of the Chinese Academy of Engineering. Professor Liyuan Chai has devoted himself to the research in the field of non-ferrous metallurgy environmental engineering for decades. He invented a number of non-ferrous smelting pollution control and recycling technologies, such as clean metallurgy of arsenic-containing polymetallic materials, recycling of smelting waste acid, purification and reuse of heavy metal wastewater. These accomplishments have achieved large-scale promotion and application and promoted the industrial transformation, upgrading and green development of non-ferrous industry. He has won 2 second prizes of National Technological Invention Award, 1 second prize of National Science and Technology Progress Award, 8 first prizes of provincial and ministerial level scienceand technology awards, and Ho Leung Ho Lee Industrial Innovation Award.Dr. Zhihui Yang received her Ph.D. degrees in Plant and Environmental Science from Norwegian University of Life Sciences in 2006 and in Crop Planting and Cultivation from Hunan Agricultural University.
