Evaluating the Impact of Students' Attitudes on Waste Management in Federal Colleges of Education, Southwest Nigeria

The global increase in waste generation, driven by accelerated population growth, industrialization and rising consumption, has overwhelmed public waste management systems, necessitating the need for active participation of individuals and institutions in promoting environmental sustainability. Higher education institutions play a crucial role in promoting responsible waste management practices and environmental awareness among students. This study assessed the impact of students’ knowledge and behavioural intentions on waste management in Federal Colleges of Education in Southwest Nigeria. A descriptive survey design was adopted, with a sample of 386 respondents randomly selected from a population of 11,320 students across the four Federal Colleges using Taro Yamane's sampling formula. Data collected through a structured questionnaire were analyzed using SPSS (version 26) and Smart PLS. The findings revealed a statistically significant relationship between students’ knowledge and waste management (t = 9.260, p < 0.001), indicating that knowledge has a strong influence on waste management outcomes. Behavioural intention also emerged as a strong predictor of effective waste practices (t = 8.277, p = 0.000). The study concludes that awareness of the consequences of improper waste disposal enhances students’ willingness to participate in clean-up activities and adopt sustainable waste practices. Although attitude showed limited direct influence, peer interaction, proper orientation, and adequate facilities can strengthen students’ commitment to sustainable campus waste management. It is therefore recommended that college administrators integrate waste management principles into the curriculum and create platforms that empower students to serve as sustainability ambassadors promoting environmentally responsible practices within and beyond the campus.
