Environmental Infrastructure Engineering, Water Treatment Engineering and Solid Waste Engineering

Good quality water is, along with abundant water, one social infrastructure. A variety of water treatment technologies have been developed for providing good quality water, but to eventually achieve a low carbon society, we must assess the current water utilization systems, or collect information needed to obtain a consensus for making up new water utilization systems. It is, therefore, necessary to clarify the actual state of water environments in the natural world and human activities which act on these, and to do so, I wish to propose the application of appropriate treatment technologies and installation of treatment systems into an area in order to maintain and conserve the water quality which living people desire. In my present lab, we are measuring the stable isotope ratio of oxygen or hydrogen and the nitrogen in nitrate-nitrogen in water, measuring pollutants such as agricultural chemicals in the environment, and developing low energy consumption water treatment methods. With the Kofu Basin as the home field of our research, I wish to apply methodology obtained there to the countries of Asia. Also I wish to prepare design drawings for river basin management cooperatively with students from each Asian country.

It is vital to correctly manage wastes not only to prevent environmental pollution, but to conserve resources. But the public state of waste management (present legal requirements, economic circumstances, level of technology, concepts of wastes and customs) varies infinitely between countries and regions, and appropriate management also varies according to circumstances. We are studying appropriate waste material management through research on composting of biological waste, or research on evaluating the toxicity of wastes.

I study the relationships between organisms and environments that lead to resolve environmental problems. I am engaged in research on bioremediation, phytoremediation and rhizoremediation with elucidation of the role and contribution of bacteria and plant.

Waterborne pathogens, such as enteric viruses or protozoa, cause serious health problems in many areas of Asian countries. Based on field surveys on the occurrence of the waterborne pathogens, we quantitatively determine the health risks of these pathogens in the aquatic environments in Asian countries. Our final goal is focused on establishing an appropriate system for controlling the health risks of the pathogens via contaminated water.

We are studying on environmental cleaning and conservation using natural purification systems and bio/eco-technologies. Our main research fields are shown as follows.
1) Waste and wastewater treatment
2) Bioremediation and phytoremediation of polluted soil and water environments
3) Environmental monitoring and assessment
4) Resource and energy production from waste and wastewater

Water resource deficiency is a global urgent problem in recent years, and 20% of the world population is inaccessible to clean and safety drinking water. Especially, the water supply is under serious situation in China. This deficiency is caused by environmental water pollution as well as decreasing precipitation and increasing human population. The environmental pollution also impacts the human health and ecosystems. In Japan, the pollution by persistent organic pollutants is actualized in several main sources of water supply like Lake Biwa and Kasumigaura. Therefore, we have been studying about developing a novel environmental remediation techniques at low cost with minimum environmental impact by taking advantage of potential biological activities of higher plants and accompanying microorganisms.
