Reverse logistics applied to used cooking oil: study of soap production as a sustainability enhancement

Abstract

This article focuses on enhancing Environmental Education as a strategy to address the improper disposal of residual vegetable oil, a common practice in communities with limited access to information. Although there are national policies and international agreements aimed at sustainability, this problem persists silently. The study originated after the implementation of environmental preservation projects with high school students at Escola Estadual Fagundes Varela, in Braúnas-MG, including a technical visit to the landfill of the neighboring municipality. During a discussion circle, it was observed that the residual oil was not being disposed of in an environmentally appropriate manner. The students conducted research in their micro-regions, confirming the improper disposal. Based on this, an environmental education intervention was developed using a qualitative-quantitative approach, applying questionnaires before and after the educational activities. As a sustainable solution, an ecological soap recipe was developed from used oil, integrating the principles of Reverse Logistics and the Circular Economy. The results highlighted an increase in knowledge and greater awareness among the population involved, demonstrating the school's role in shaping young leaders capable of acting as socio-environmental multipliers. The project helped to mitigate environmental impacts, reduce waste, and promote sustainable practices, fostering socio-environmental responsibility and local entrepreneurship with a global perspective.
