Waste separation behaviours at source among UiTM student: An application of Theory of Planned Behaviour

Abstract

A study on waste separation at source behaviour was conducted among students to determine the factors that most influence their intention to conduct source separation behaviour. In this cross-sectional study, 197 undergraduate students from Faculty of Health Sciences, UiTM were involved. An online questionnaire was administered for assessing socio-demographic and Theory of Planned Behaviour (TPB) constructs which composed of attitude, subjective norms, perceived behavioural control (PBC), separation intention, and waste separation behaviour. The findings demonstrate that subjective norms are the factor that most influence the intention to perform waste separation behaviour, whereas PBC is the critical factor that directly influences the waste separation behaviour. The necessary infrastructure should be rationally and adequately provided, and in order to improve the norms, a comprehensive education and promotion campaign should be implemented and widely disseminated to increase people's understanding of the need of waste segregation.
