The present paper presents a comparison of two models for supplying Waste Cooking Oil (WCO) to a biodiesel plant considering Santiago de Cali as a case study. The analysis takes the results obtained from a base model using mixed integer linear programming under economic, operational and environmental indicators. Later, a system dynamic model is proposed, considering the linear model variables, and including others to enhance the model’s outputs and scope. The system dynamic model’s outputs were very close to the linear model, with a maximum percentage difference around 7.8%. The study also identified that 23.93% of the cooking oil consumed is converted into WCO. A potential reduction of 13'000 tons of CO2 per month could be achieved if the collected WCO is used to produce biodiesel, and this biodiesel replace the same amount of diesel. It is concluded that the dynamic model allows to visualize the behavior that an AUC collection system can generate over a long period of time.
