SOCIO-ENVIRONMENTAL SUSTAINABILITY IN SCIENTIFIC EDUCATION: IMPACTS OF REUSING COOKING OIL FOR SOAP PRODUCTION IN THE CONTEXT OF AN INTEGRAL SCHOOL

Abstract

This article presents an educational and socio-environmental project developed at ECIT Nenzinha Cunha Lima, Campina Grande, Brazil. The main objective was to foster environmental awareness and sustainability through the reuse of cooking oil discarded by the school’s kitchen, turning it into handmade soap. The initiative involved teachers and students from the Natural Sciences area, combining theoretical knowledge in chemistry, biology, and mathematics with practical laboratory and citizenship activities. The process included oil collection, proportion testing, and pH control, resulting in effective soap production with high user approval. Students gained practical and theoretical understanding of chemical reactions, sustainability, and environmental care, while school staff reported economic and ecological benefits. The project culminated in a public presentation and the distribution of educational materials. Questionnaires confirmed high satisfaction rates and environmental engagement among participants. This experience highlights how integral education can be a powerful tool for promoting sustainability, social responsibility, and the development of scientific skills in line with Brazil’s National Common Curricular Base (BNCC).
