This study applies semi-structured interview, mathematical formulation and simulation modelling. The results reveal that the theoretical recovery rate among the majority of respondents is higher and the actual recovery rate among respondents is lower than it should be.

The establishment of a waste bank could be a social engineering tool for changing the mindset of students. This waste bank can be managed and made useful via the so-called “3R” concept (reduce, ...reuse, and recycle), which is the main principle used by waste banks. This study aimed to determine students’ interest in managing waste. The sample comprised three classes of students who are enrolled in natural resource economics courses from the Economics and Business Faculty of the University of Brawijaya. Each class has 31 students. Quantitative multivariate research was performed using a Likert scale. Validity and reliability tests were performed for behavioral control and to manage waste variables. Data analysis was used Multivariate analysis, and Bartlett’s test of sphericity was used for significance of the data. Results show that the behavioral control variable was positively correlated with and was influenced by the intention to manage waste or the interest in managing waste. We suggested that waste bank systems—in which waste can be exchanged for food or other products—could be applied in campus environments and that a waste bank should be established in the Faculty of Economics and Business of the University of Brawijaya.
