Abstract: The recycling of agricultural and agro-industrial residues has emerged as a key strategy for promoting sustainability and mitigating environmental impacts. Among these residues, used cooking oil represents one of the major environmental challenges due to its improper disposal, which can cause water pollution and compromise ecosystem balance. In this context, the present study aimed to raise awareness among the population of the municipality of Valença do Piauí regarding the importance of environmentally appropriate disposal of waste cooking oil, combining educational actions with the production of biodiesel from the collected used oil. The adopted methodology comprised environmental education activities focused on guiding the community on the correct disposal of residual oil, as well as its systematic collection. The obtained oil underwent filtration and pre-treatment processes and was subsequently used as feedstock for biodiesel production through the transesterification reaction. The produced biofuel was evaluated through physicochemical, chromatographic, and spectroscopic analyses in order to verify its quality. The results showed that the biodiesel exhibited a chromatographic profile with a predominance of linoleic and oleic fatty acids, as well as physicochemical parameters compatible with the limits established by the Brazilian National Agency for Petroleum, Natural Gas and Biofuels (ANP), except for oxidative stability determined by the Rancimat method. Infrared spectroscopy analysis confirmed the efficient conversion of triacylglycerols into methyl esters. Thus, the results demonstrate the technical and environmental feasibility of utilizing waste cooking oil for biofuel production. It is concluded that biodiesel production from used cooking oil presents significant socio-environmental potential, as it transforms a highly polluting waste into a clean energy source, reduces the environmental impacts resulting from improper disposal, and strengthens sustainable practices and the circular economy in the regional context.
