Abstract:
Background and Objective: Improper disposal of medicine has led to environmental damage and human health hazards. However, the recent increase in public awareness of the importance of recycling provides an opportunity to address these problems. This study, evaluated the influence of public values on participation in unused medicine recycling. Materials and Methods: Values were analyzed through multiple-criteria decision analysis. First, Nagai’s 5W1H method and interpretive structural modeling were performed to identify key factors and construct hierarchies. The weighting priorities of factors were then determined through the analytic network process and grey relational analysis was conducted. Questionnaires and interviews were administered to patrons of pharmacies and hospitals and the results were analyzed using super decision. Results: Resource maintenance was the key value in the first hierarchy, indicating that the public is concerned regarding whether medical resources are consumed efficiently. In the second hierarchy, the key factors were environmental protection, concept identity and personal moral cognition, suggesting that cognition and internal feelings are stronger motivators of participation in recycling than legal regulations. Finally, the key values in the third hierarchy were a sense of identity and a sense of belonging, implying that people consider the beliefs of family, friends and other community members in their decisions regarding recycling. Conclusion: According to the findings, three main conclusions were drawn. First, appealing to resource maintenance is an effective approach to promoting unused medicine recycling. Second, legal and moral regulations are not effective means for increasing public willingness to recycle unused medicine. Instead, governments should focus on changing public perception. Finally, promoting social communication is a useful technique for increasing recycling activity. Therefore, incorporating social networking is recommended into recycling promotion programs.
