Abstract

Large amounts of edible oils are discarded each day from various sources, principally from households. When disposed wrongly into the nature, they can reach the ground, reducing the absorption of nutrients from plants, the aquifers, making them unusable, and finally, water surfaces, affecting the aquatic systems. From a circular economy perspective, one essential condition is looking for alternatives to reuse the used cooking oil (UCO). The objective of this paper was to discuss the application of Geographical Information Systems (GIS) to map the renewable energy potential for three possible waste-to-energy potential paths: biodiesel, anaerobic digestion, and direct combustion for the city of Guayaquil. For the cases of biodiesel (a), methane (b), and direct combustion (c), maximum values of 95, 88, and 95 MJ/kg/person, respectively, were found. Finally, Tarqui parish has much higher values than Ximena and Pascuales. Given its potential, the collection should start from this parish as a pilot project.
