This study assessed how student involvement affects the development of waste management policies in secondary schools located within Kanungu District, Uganda. It highlights methods of waste disposal in secondary schools, the effects of waste generated from schools, and challenges facing the management of waste in secondary schools. The study critically analyzed dimensions through which students’ active involvement has an impact on the development and successful implementation of waste management policies in secondary. It brings out different aspects in which students’ engagement is central to different environmental programs. When they own the process, responsibility is instilled among them, thus making such practices more effective and sustainable wherever applied in a secondary school. It further stressed the fact that the cooperation of students, educators, and local authorities is very imperative in the development, modification, and adoption of any effective, as well as inclusive, sustainable waste management policies. Other significant aspects are that student campaigns sensitize not only within the schools but also a larger community, hence this reflects the wider implications of student involvement in environmental stewardship. This paper pushes for the use of student participation in policymaking not only in Kanungu District but also in other parts of Uganda and even wider areas, leading to a more enduring and accountable way of dealing with the environment.
