Riobamba located in the Republic of Ecuador, has 255 741 inhabitants, has no data on used vegetable oils, nor projects for its use, so the objective of this study was to establish: consumption of domestic vegetable oils, generation of domestic used vegetable oils, disposition habits of these residues and their characterization to evaluate potential uses. 60 families participated during five months with collection of residual oils, volume measurement and data reporting, 394 surveys were applied, after than to do the statistical analysis was established: consumption of edible oil of 5.16 L / year / inhabitant, generation of residual oil 1.52 L / year / inhabitant, and, with 70.97% that expressed their intention to deliver its waste oils to collector they would be collected 275.19 m3 / year / population. After of one pretreatment of the residual oil was characterized according to Mexican standards, it was obtained: humidity 0.068%, relative density 0.9641, acid number 1.13 mg KOH/g, free fatty acids 0.49%, soap content 0%, saponification number 192.48 mg KOH/g, ester number 191.35 mg KOH / g, and unsaponifiable matter 0.471%; these results identify a suitable raw material for some processes: theoretically, 255.9 m³ of biodiesel would be obtained by alkaline trans esterification; or by saponification 213 356.4 Kg of soap, in addition to other alternatives.
