Rapid growth in nanotechnologies promises novel benefits through the exploitation of their unique indus-trial applications. However, as the production volume of nanomaterials increases, their unintentional exposure to the environment has been occured. Potential impacts of nanoproducts on the environment can be evaluated in the life cycle assessment (LCA). LCA is the systematic analysis of the resource usages and emissions over the life time from the pri-mary resources to the moment of disposal. In this study, we performed LCA for fabrication processes of superhydro-philic oil/water separator using nano-TiO<sub>2</sub>. TOTAL<sup>TM</sup> freeware was used to analyze for all fabrication processes, and 6- environmental impact factors (resource depletion, climate change, ozone depletion, acidification, eutropication, and pho-tochemical oxidation) were introduced. In addition, the use of nano-TiO<sub>2</sub> in the fabrication of superhydrophilic oil/water separator was actively contributed to the environmental impact factors, compared to the bulk-TiO<sub>2</sub>.
