Associate Professor / HIMENO Shuji
Prof. Komatsu focuses on the research involving anaerobic digestion and water treatment, where Prof. Himeno accurately aims and engages several environmental issues through research with the cooperation of other companies and associations. Both professors positively instruct and discuss with their pupils to provide them support for their respective investigations.

Research Content

In our laboratory, we are developing technologies that take advantage of local properties of the sewerage structure of Niigata Prefecture, under the theme of "Building a Resource-Energy Recycling Society”, based on the recovery and utilization of unused resources obtained from the sewage systems to generate energy. In addition, we also cover other themes like methane fermentation using biomass, the pretreatment of sludge using ozone, harvest of plants managing sewerage systems, removal of harmful metals deposited on roads using porous concrete, and the development of zeolite membranes and MOF technologies for green gas mixtures separation and storage.

A Day in the Lab

Each of our laboratory’s different areas conduct experiments at the campus installations or/and sewage treatment plants. We also participate in various events throughout the year such as harvesting rice, maintenance of facilities used for our research, or exhibiting about our research/themes in the Nagaoka Festival. Thanks to these events we have the opportunity to interact with people outside the university which are part of important companies, acquiring the needed knowledge and skills for the future laboral life like formality for business conversations, e-mailing and other aspects.
