Planning a biodigester in a school in Maré: critical environmental education and social technology

Abstract

The inequality in access to basic sanitation and a balanced environment stems from political choices within an exclusionary socioeconomic model that creates sacrifice zones, such as favelas, to sustain itself. Science and technology are embedded in this context, and when claiming neutrality, they serve hegemonic interests. In the fight for environmental justice, it is crucial to consider sanitation solutions in favelas. This article reports on the participatory planning experience of a biodigester with students at the Escola Estadual Professor João Borges de Moraes in Maré, as part of a critical environmental education process. Using practical experience systematization, the study emphasizes participant observation and lesson plan analysis. The results highlight the active role of students, the relevance of the practice for teaching, and participant education on the topic. The article's contribution lies in demonstrating how critical environmental education and social technology can help reduce inequalities through critical thinking, solution creation, collective engagement, and public policies focused on sanitation.
