Clues of an environmental education for solid waste management: What do children draw in a municipal school in Cambé, PR?

This research looks at how specific teaching methods in municipal schools can improve awareness of municipal solid waste management (MSWM). The study focuses on a case in Cambé, Paraná, and tests an environmental‑education program built around a “Composting at School” workshop. Environmental engineering students designed and ran the workshop, using interactive activities, educational games, and guided discussions to teach primary‑school children sustainable waste habits. To measure the workshop’s effect on knowledge and attitudes, the researchers used both qualitative and quantitative methods. They examined children’s drawings and responses to structured questionnaires. The drawings were sorted into categories to see how well the kids understood organic‑waste recycling, the composting process, and their

own environmental responsibilities. The results show how university outreach can shape early environmental behavior and suggest a model that can be expanded to other municipal school curricula. The project also offers detailed guidance for creating, assessing, and recording community‑based environmental‑education programs within municipal waste‑management systems.
