Circular economy is believed to be the latest approach to replace the linear economy. However, in the context of higher education institutions, the awareness and sustainable practices regarding circular economy is still at par. Recent studies show that knowledge about the circular economy has not yet spread widely among university students. This study was done to identify the level of knowledge related to circular economy concept among undergraduate students. This study uses a quantitative methodology through a survey using a questionnaire towards 35 undergraduates' students in Universiti Teknologi Malaysia. Cronbach's alpha value of 0.93 shows high reliability of the questionnaire items. The data obtained was analyzed using SPSS software version 20 and reported descriptively. The results of the study show that there are seven items in the circular economy knowledge domain, and all of these items have a high mean value. This shows that UTM undergraduate students have extensive knowledge about the circular economy. The results of this study provide a meaningful contribution to stakeholders in planning appropriate curricula and programs for undergraduate students in higher education institutions. With a clearer understanding of students' level of knowledge about the circular economy, steps can be taken to strengthen knowledge about the circular economy in undergraduate education at UTM.
