Abstract
Today, environmental pollution arising from the use of fossil fuels has posed an essential challenge to the world. Political and scientific decision-makers are looking for a way to reduce environmental pollution. One solution is the production of biogas energy to replace fossil fuels. This study aimed to estimate the potential of biogas production from livestock manure to replace fossil fuels and reduce pollution. The research used polynomial linear mathematical programming to optimize three objective functions with the nexus model approach under interval uncertainty in Urzouyeih County. The results showed that the region could produce 3.07 × 108 MJ of clean energy to replace fossil fuels from animal manure, equivalent to 8.3 × 107 m3 of natural gas. Also, the total CO2 emission and land pollution from animal farming activity was estimated at approximately 1.7 × 107 kg. Therefore, to reduce the consumption of fossil fuels and environmental pollution, the process of producing biogas from livestock waste is suggested to be included in the region's development plans.
