The use of chemicals in the industry draws various environmental and health impacts. When we design a production process which uses chemicals, risks caused by use and release of chemicals should be appropriately evaluated. In this study, industrial cleaning process, which uses a considerable amount of chemicals, is investigated. To reduce risks originated from cleaning process, many technologies and alternative cleansing agents have been developed and applied. However, such technologies are installed using empirical knowledge without quantitative evaluation. It is necessary to select alternative technologies to reduce chemical risks after evaluating risks not only about the process, but also in the whole life cycle of chemicals. We clarify concrete procedures to perform risk assessment and life cycle assessment, and propose integrated methodology to evaluate and design a cleaning process.
