Evaluation of biogas generation potential from human excreta as a sustainable energy solution in Villa El Ángel settlement, Independencia, Peru

Abstract

This study estimates the potential for biogas generation from human excreta in the Villa El Ángel settlement, Independencia, Lima, Peru, by adapting a methodology applied in a similar context. The energy viability is analyzed within a vulnerable urban setting characterized by limited basic services and predominant use of firewood for cooking. The results indicate that anaerobic digestion can be a renewable energy source with positive environmental and health impacts. Additionally, limitations were identified such as irregular terrain, which complicates the installation of biodigesters. Therefore, it is recommended to implement pilot projects and conduct a soil study to evaluate the topographic conditions of the settlement, ensuring the proper installation and operation of biodigesters on uneven terrain.
