Courses
  • CSE29371 – Environmental Chemistry
    This course will teach you the basic chemical processes that can affect the quality of air, water and soil. You will study the basic chemistry concepts in both the natural and human perturbed systems. After the course, you should be able to identify the chemistries behind some environmental issues. Through the tutorials and experiments you will obtain the basic skills and the “engineering sense” to quantitatively evaluate certain environmental phenomena. The fundamental developed in this course will be also useful to help you study more advanced subjects and to conduct environmental research in the future.
  • CSE520 – Solid and Hazardous Waste Management
    This course is designed to provide student the fundamental concepts for management and treatment of the municipal and hazardous solid wastes. The courses will begin with an introduction of the generation of the solid wastes due to human activities. The students will study both the state-of-the-art strategies and the innovative techniques with great potential for solid wastes treatment. The details of the courses will cover the scientific background and the real-world examples to better understand the problems of solid waste treatment policies and alternatives in Hong Kong.
