This study aims to explore the perception and habits regarding single-use plastics (SUPs) among students at the High School for Gifted Students, University of Sciences, Hue University (HUSC’s HFGS). Using a descriptive approach, data were collected from 151 students via questionnaires and field observations. Findings indicated that although 85.4% of the students possessed a high awareness of SUPs and 72.8% were aware of the eco-friendly substitutes, the usage was still high due to convenience, availability, and price factors. Plastic bags, foam containers, and plastic bottles were frequently used items, and habit loops were perpetuated by time constraints and no other options. Despite these barriers, 85.5% of students expressed willingness to switch to alternatives if they were accessible and convenient. Students were in favor of supportive actions, including promotional activities (82.1%), providing reusable items (77.5%), and incentivization (74.2%), in contrast to only 37.7% in support of a complete ban. The study underscores the need for collaboration among schools, businesses, and students to address practical barriers and foster sustainable habits. Suggested interventions comprise raising awareness, investment in infrastructure, and incentives to support the sustained change of behavior. This approach may serve as a replicable framework for educational institutions across the region.
