In the study, results such as the amount of animal manure and agricultural wastes, biogas potential, and electricity generation from biogas are mapped for 12 regions and 81 cities. Additionally, the rate of meeting the electricity demands of cities is found if the biogas potential is converted into electrical energy. Besides, the costs of biogas plant installations for the cities with the highest biogas potential in each region are calculated according to the highest investment conditions. Later, as a result of using biogas for electrical energy, the reduced CO2 emissions are calculated. According to the results, Turkey's total collectible manure, total collectible agricultural waste, and biogas potential are more than 176 million tons, 17 million tons, and 17 billion m(3) per year, respectively. Turkey's electricity generation potential and total CO2 emission reduction are more than 38 GWh and 174 million tons per year, respectively. The lowest payback period on investment is determined in the selected city of the Mediterranean region with 5.14 years, while the highest is in the Northeastern Anatolia region with 7.55 years. The results obtained will guide the priority given to the region and type of waste in biogas plant installation. Moreover, it will enable comparison with the investment costs of other renewable energy sources.eninfo:eu-repo/semantics/closedAccessBiogas potential of TurkeyAnimal manureAgricultural wasteElectricity generationCO2 emissionBiogas plantInvestment costArticle10.1007/s13399-022-02538-62-s2.0-85126271301536211Q3534512WOS:000769824500003Q2
