Mengjun Chen, Ph.D.

Position
    Professor, Southwest University of Science and Technology; Vice-Director, Key Laboratory of Solid Waste Treatment and Resource Recycle (SWUST), Ministry of Education.  
Research Interests
   Technologies for “urban mining” comprehensive reutilization are at the forefront of modern science and technology research efforts due to the rapidly increasing global demand for resources and the growing environmental concerns. To provide sustainable resources and a better world for future generations, significant improvements to the current state of these technologies is imperative. My current research interests are primarily focused on the development of green and effective approaches for recycling resources from urban mining. In general, my research activities include life cycle assessment, characterization, recycling and pollution control studies of solid waste, especially e-waste, hazardous waste and nuclear waste, as well as the unique, nanostructured materials recycle from urban mining for use in environmental pollution control. Specifically: 
    Characterization ----- life cycle assessment on human toxicity and eco-toxicity 
Green and effective recycling technologies for solid waste, especially for e-waste, hazardous waste and nuclear waste
    Processing pollution control
    Unique secondary materials for environmental application, such as water treatment 
Lecture Concepts
    Teachers propagate the doctrine, impart professional knowledge, and resolve doubts. Therefore, teachers should lead the students to form their own concept about the world, value and science, and most importantly to learn how to propose, analyze and solve the problems prior to impart professional knowledge.
