Assessing the fate of chemicals in the environment and engineered processes
Concentration changes and dynamics of environmental chemicals are predicted and evaluated based on partition equilibrium properties of chemical compounds and their conversion/degradation kinetics. The target compounds are organohalogen compounds, PAHs, and other emerging pollutants. The target engineering processes include water treatment and gas cleaning, and solid/liquid waste treatment in such environmental media as water, air, soil, and sediment.
Safe and appropriate disposal treatment of waste water, flue gas, and solid/liquid waste, and developing further technology for recovering materials/energy from waste
Various exhausts, such as wastewater, flue gas, and other anthropogenic waste emissions should be appropriately and safely disposed. Currently, material and energy recovery is highly desired in the context of establishing a sound material recycling society.
Because energy recovery from waste treatment plays a key role in eliminating fossil fuel use and GHG emissions, research and development corresponding to the type and properties of waste are performed. Safety assessments of the systems are also conducted.
