Purpose: The purpose of this study is to develop and empirically test a model that can predict factors affecting student recycling behavior. The theoretical model was based on motivation, place attachment, environmental concern and interpersonal altruism. Design/methodology/approach: A cross-sectional study was conducted with college students in Taiwan using self-report questionnaires. Of the 800 distributed questionnaires, 523 were completed (response rate of 65.4%) and were analyzed using structural equation modeling. Partial least squares (PLS) were used to test the models and hypotheses. Findings: The results showed that environmental concern, motivation, interpersonal altruism and place attachment have significant positive effects on recycling behavior and motivation and place attachment have significant positive effects on interpersonal altruism. This research contributes to the existing literature by discriminating between two sorts of motivation: intrinsic and extrinsic. Based on these findings, suggestions for future research and practical implications are presented. Originality/value: Few studies have linked motivation, interpersonal altruism, environmental concern and place attachment to recycling behavior. Therefore, this study aimed to explore these relationships, specifically as they affect college students' behavior. This paper anticipates that increased knowledge about recycling behavior could be used to support the wider adoption of recycling practices.
