Due to the growing trend of urban waste production and environmental pollution caused by it, are among the factors that have forced mankind to try to obtain renewable fuels. In case of Isfahan city, an average of 1000 tons of urban waste is produced daily and 76% of it is organic matter. Therefore, in the direction of producing renewable fuels, there is a potential for biogas production.This research has a descriptive-analytical view, which is purposed at development and application. The method of collecting information is the library and survey, and in addition to that, direct survey, reliable sources have also been used. The municipal waste was analyzed according to Hans method according to the VDI 46030 standard, and the biogas analysis was done using a gas chromatograph equipped with a TCD detector, and also to check the potential of biofuel production after digesting the dried waste, the amount of free sugar It was checked by DNS method, then after detoxification and fermentation, the amount of bioethanol in the obtained samples was measured by HPLC. The results show that for 6 kg of organic waste after 54 days of anaerobic digestion, an average of 490 ml/gr of biogas was obtained, 60% of which is methane, and 8 grams of ethanol were produced for 20 grams of dry waste. According to the studies, if 5% gasoline is used in Isfahan city, the carbon monoxide pollution index will decrease by 11% and the suspended particles index will decrease by 67%.
