    The objective of this study was to determine the biogas generation potential from organic waste in the parishes of Nazón and Sageo (Biblián). The problem addressed is related to the deficient management of Municipal Solid Waste (MSW), considering that more than 50 % of the waste generated is organic matter that does not receive adequate treatment, contributing to the emission of Greenhouse Gases (GHG), primarily methane and carbon dioxide. The research began with the collection and analysis of information on waste generation in the Biblián canton during the period 2017–2024, as well as a projection to the year 2035. Subsequently, household waste was sampled and characterized, evaluating parameters such as composition, moisture, volatile solids, and C/N ratio. A Biochemical Methane Potential (BMP) assay was carried out under controlled conditions, with 12 assays per parish. The results showed a potential of 16.386 NmL/kg for Nazón and 13.415,6 NmL/kg for Sageo. Based on these values, an average energy generation of 609,8 kWh/year was estimated for Nazón and 289,9 kWh/year for Sageo, considering a combined heat and power (CHP) system with an efficiency of 35 %. These results represent a reference scenario for energy utilization. Finally, it was determined that factors such as waste composition, moisture, pH, pressure, volatile solids, and C/N ratio directly influence the efficiency of the anaerobic process, allowing for recommendations aimed at the valorization of organic waste and the strengthening of the circular economy.
