Using the rising production of organic waste for its conversion to energy (WtE) helps reduce the issues related to its eventual disposal and is a global trend that is becoming more prevalent. Using source separation and selective collection, this study proposes a novel method for identifying and prioritising WtE alternatives that can be used with Food Waste (FW) that is present in a Colombian municipality's Municipal Solid Waste (MSW). The prospective MIC-MAC method (Matrice d'Impacts Croises Multiplication Appliques a un Classement) allowed the selection of criteria and sub criteria; the Analytical Hierarchical Process (AHP) and the Technique of Order of Preference by Similarity to the Ideal Solution (TOPSIS), allowed a ranking of selected alternatives taking into account the technical, environmental, and social factors; and the MIC-MAC method allowed the selection of criteria and sub Anaerobic digestion, gasification, incineration, biogas recovery from landfills, and pyrolysis were the WtE technologies discovered. Pyrolysis was left out because of its wider application potential with substrates like plastic waste.
