Keio University Faculty of Science and Technology and MANN+HUMMEL Japan Ltd. (M+H), together with Yokohama Industrial Development Corporation (IDEC Yokohama), have taken the first steps in their endeavor to create “subways with the world’s cleanest air.” This collaborative industry-academia undertaking, which has been adopted as a designated research project by the Keio Leading-edge Laboratory of Science and Technology (KLL), seeks to develop new and unprecedented technologies that will remove dust generated by subway carriages, brakes, and other means. It aims to achieve this by combining Keio’s expertise on particle electrostatic charging with the latest filtration technologies possessed by M+H. The subway has a great influence on people’s living environment and is an indispensable part of the transportation infrastructure in urban areas of Japan. For the first stage of this project, the behavior of PM2.5and other particulate matter inside subway stations will be analyzed. The initial field studies began on July 17.
