Baoping XIN(1969-), male, Doctor of Science, Professor. Engaged in theoretical and technical research on resource utilization of industrial waste/hazardous waste. Director of Chinese Society of Environmental Sciences, Chief Scientist of Hydrometallurgical Branch of China Materials Recycling Association, Deputy Chairman of Solid Waste Professional Committee of Chinese Society of Environmental Sciences, Deputy chairman of Heavy Metal Pollution Prevention Professional Committee of Chinese Society of Environmental Sciences, Deputy chairman of Environmental pollution Prevention Professional committee of China Non-Ferrous Metallurgy Society, and academic committee of National Hazardous Waste Treatment and Disposal Technology Alliance Vice Chairman of the Committee, Vice Chairman of the Special Committee on Solid Hazardous Waste and Contaminated Soil of All-China Environmental Protection Federation, and Vice Chairman of the Hazardous Waste Professional Committee of China Renewable Resources Recycling Association. In Chemical Engineering Journal, Bioresource Technology, Journal of Hazardous Materials, Waste Management, ACS Applied Journals such as Materials and Interfaces have published more than 100 SCI papers, 40 high-level SCI papers (Region 1), and more than 30 invention patents. For the first time in the world, it created a series of concepts such as heavy and dangerous waste, metal 5-point method, three-dimensional attribute and fine classification, and constructed a theoretical system for the resource utilization of heavy and dangerous waste. The membrane bioreactor (MBR) was first introduced into the field of bioleaching, which solved the industry problems of long cycle and small throughput of bioleaching technology. He wrote the first monograph on the utilization of critical and dangerous waste resources. Presided over the first research on the development status and technical requirements of the national waste and disposal industry; Presided over the research and development of the first 100 m3 class electroplating sludge valuable metal bioleaching and recycling enrichment complete sets of equipment and process for the heavy and dangerous waste industry; The high value utilization of industrial solid waste/heavy and hazardous waste has been pilot-tested and demonstrated in several fields.
