The purpose of this study was to investigate the feasibility of obtaining biodiesel using calcined agroindustrial residue ashes from Huasaí (Euterpe oleracea mart) as a solid catalyst in the transesterification of used vegetable oils. The agroindustrial residues were collected from Negocios Agroindustriales Loreto NALSAC, while the used vegetable oil was obtained from the facilities of FUNDESAB. A comprehensive physicochemical characterization of the used vegetable oil was conducted, revealing moisture values of 0.76% and acidity degree of 0.62%. The Huasaí agroindustrial residues underwent a drying process at 90°C for 2 hours, followed by pulverization and calcination at 700°C for 4 hours to obtain the CCRAH catalyst, whose analyses revealed a potassium concentration of 16.51% and calcium of 7.19%.During the direct basic transesterification reaction, a maximum biodiesel yield of 80.49% was achieved using a molar ratio of 9:1 with a 4% catalyst. Analysis of variance revealed a p value < 0.05 for a significance level α=0.05, indicating significant differences in the biodiesel yields obtained in the various transesterification trials. In conclusion, it was determined that calcined Huasaí agroindustrial residues exhibit great potential as a catalyst in the production of biodiesel from used vegetable oils, primarily due to the presence of potassium and calcium in their chemical composition.
