摘要

The Environmental Protection Law No. 72/2020/QH14 requires mandatory sorting of household municipal solid waste in Vietnam. Despite this decree, waste sorting remains a challenge. This research seeks to assess the knowledge, behavioral intentions, and influencing factors associated with waste separation by young people in Hanoi, Vietnam. The extended Theory of Planned Behavior was used as the theoretical framework. Online survey was disseminated via snowball sampling to citizens aged 15–25 in Hanoi, Vietnam, and results from 319 respondents were analysed using SPSS 20.0 and R for statistical tests and structural equation modeling (SEM) analysis. Results showed that young Hanoians are generally willing to sort waste. SEM analysis showed that attitudes toward waste sorting, moral norms, and propaganda have a significant positive direct effect on behavior. Respondents who “often” or “sometimes” collect, sort, and dispose of waste in their household are more likely to score higher than those who do not (5.51, 5.52, and 4.69, respectively). Respondents from the highest familial incomes scored the lowest on average (4.26). Females tend to score higher than males (5.61 and 4.94). These findings highlight the need for targeted educational interventions and youth-focused communication strategies to support compliance with national waste-sorting regulations.
