Wastes spread to the environment negatively affect the health of humans and all other creatures. It is the responsibility of each person to assess the waste generated correctly. Recycling is an applicable option for environmental protection. This study defines university students' recycling behaviours based on the Theory of Planned Behaviour using Structural Equation Modelling. The results of the study, it is found that subjective norms and perceived behaviour control have a significant impact on students' recycling behaviour. Furthermore, intention partially mediates the positive relationship between subjective norm and recycling behaviour and between perceived behavioural control and recycling behaviour.
