Biomanager Optimization Model for Enhancing Biogas Production from Cattle Farming in a Circular Economy System
Energy access remains a challenge in rural Ecuador, where agricultural farms have modest but unmet energy needs. Traditional cooking methods depend on liquefied petroleum gas and firewood, contributing to deforestation and poor air quality. The general objective of this study is to design and i...

Energy access remains a challenge in rural Ecuador, where agricultural farms have modest but unmet energy needs. Traditional cooking methods depend on liquefied petroleum gas and firewood, contributing to deforestation and poor air quality. The general objective of this study is to design and implement a biodigester model to produce biogas from cattle waste, capable of satisfying the thermal energy needs of a rural farm in the Orellana Province located in Ecuador. To make up for renewable energy scarcity in rural regions, a cracking opportunity is presented that will create connectivity and diminish dependence on gird us robotics. Technical considerations were retention time, digester volume, and daily collection of manure. A baseline study of energy needs at the farm was conducted resulting in a design that can create 5 m³ of biogas/day. A 26 m³ digester was used, and the system demanded 312 kg of fresh manure each day. Biogas was consumed as a fuel source based on cooking, refrigeration and light demands. The biodigester managed to produce enough biogas to replace conventional energy sources. The annual substitution potential of the system was found to be 1.09 tons of liquefied petroleum gas, 2.37 tons of firewood and 4.38 MWh of electricity. It also decreased greenhouse gas emissions, saving 37.8 tons of CO₂ equivalent annually. The use of this technology also produced biol, an organic fertilizer that helps increase agricultural productivity, thus promoting farm sustainability. Biogas is presented as a renewable energy source available to rural farms in the study. We believe that the widespread implementation of biodigesters in Orellana could greatly improve energy security, environmental sustainability, and rural livelihoods. This underscores the importance of policies and incentives that support the adoption of biogas technology in agricultural communities. policies, for instance, to lower unemployment in economic downturns.
