Kimiaki Hirayama Pollution produced in our daily lives flows into sewerage systems, then the treated water flows into rivers, and it is eventually reused. Throughout the travel of this flowing water, we improve its quality by removing pollution in sewerage systems, by removing pollutants as the water flows downstream, then removing pollutants in order to use the water. We want to contribute to society by studying effective water quality improvement measures. |

Hidehiro Kaneko 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. |

Yasuhiro Tanaka 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. |

Tadashi Toyama 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. |

Hiroaki Matsuzawa Up until now, many microbes have been widely used for environmental remediation. However, a large fraction of microbes (>99%) in nature are not readily cultured. It is expected that these uncultured microbes possess new pollutant-degrading abilities, and play an important role for environmental remediation. Therefore, I would like to do research on isolating uncultured microbes and analyzing their function related to pollutant degradation. |
