Environmentally friendly industries should promote resource recycling, energy-saving, and avoid the use of hazardous substances. In this laboratory, through various research projects, we will foster environmental leaders who can solve environmental problems in the world. Preservation and management of water environment, promotion of resources recycling, and development of energy-saving industries are studied by using many kinds of tools, such as water quality analysis, micro-pollutant analysis, water, and micro-pollutant treatment technologies, land use data analysis from satellite images.
