Hosomi-Terada Laboratory



Welcome to our homepage! Environmental Bio-Engineering Laboratory (EBEL) tackles on diversified environmental issues in soil and water based on "Environmental Chemical Engineering" "Environmental Bio-Engineering" "Ecological Engineering".
 We apply multidisciplinary approaches by using these pillars to tackle on environmental and energy issues, to solve the best solution and to develop an optimized system. Our main research topics are:

Water/wastewater treatment by microorganisms and biofilm control in industries
Reduction of greenhouse gas by plants and biomass
Development of a co-benefit system allowing for wastewater treatment and energy production
Development of a decomposition technologies for dioxins and PCBs removals
