Evaluation of Biogas Potential from Rural Wastes(Case Study: Abyaneh Village)
Biogas is one of the renewable energy sources that is produced by the decomposition of organic materials as a result of the activity of anaerobic bacteria. Putrifiable materials in municipal and rural wastes are of biomass sources that can be used in biogas production. Establishment of biogas production units can be considered as an effective step to resolve waste management issues as well as emissions of environmental pollutants.The main objective of this study was to evaluate the potential of biogas production from rural wastes in Abyaneh village to address waste management issues in the region. For this purpose after quantitative and qualitative study of waste production in Abyaneh village, applicable amount of waste that can be used in biogas plants was determined and the potential of biogas production from them was calculated. The amount of recoverable biogas from organic waste produced in Abyaneh village was determined to be 24407546.68 m2 per year. On average 15864905.34 m2 of methane per year can be generated, which is equivalent to 34268195.55 MJ of energy. Obtained results demonstrated that wastes generated in Abyaneh village can be considered a suitable source for biogas production based on its quantity and composition. It is suggested to establish biogas production plants in the region which can be used to reduce the volume of wastes, transportation and disposal costs and improve human health. Also the energy produced from it can be used for cooking, lighting, power generation and transportation fuel.
