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.
