Global increase in the demand for the new Electrical and Electronic Equipment (EEE) lead to the rapid increase of waste electrical and electronic equipment (WEEE). Significant efforts on developing divers WEEE technologies are being made by many developed nations. This study focuses on developing a road map using quality function deployment (QFD) and analytic hierarchy process (AHP) for better managing and recycling of WEEE in Korea. In order to develop a roadmap on WEEE recycling technologies, a total of nine experts developed 22 different research projects of WEEE recycling. A detailed evaluation of the proposed projects was made by using AHP method with a number of experts and professionals. Evaluation of reliability and validity of the data obtained were conducted, along with SPSS statistical software. By using the QFD technique, a survey regarding potential problems, suggestions, and difficulties at several WEEE recycling facilities were conducted and evaluated. Evaluation of the proposed projects was made by the criteria, which was developed by expert meeting. The evaluation criteria were classified into upper and lower levels. AHP weights reflect the results of the final QFD analysis. In this study, proposed research projects (No 3, 5, and 10) showed higher importance index, and are related to plastic sorting technology and recovery technology of rare metals in WEEE. The proposed WEEE recycling technology roadmap emphasizes the development of effective size reduction of large household appliances and advanced screening techniques (e.g., plastics) in short period of time. In the long term period of time, the roadmap includes the development of better recovery technologies for rare metals and valuable materials during refinery process of WEEE.
