Abstract

Pakistan is facing energy scarcity. The biogas is one of the renewable substitutes. It does not only overcome the energy scarcity but also harness the energy from animal dung which causes the CO2 emissions. The present study was done on the appraisal of potential of biogas from the dung of animals (Buffaloes, Cows, Goats and Sheep) within the villages surrounded by Taluka Saeedabad. The purpose of the study was the energy potential of the biogas and the selection of the most suitable design and size of the biogas plant for the villagers. The present study also includes the domestic biogas plant economics. As per the estimation, total quantity of animal dung generated was about 129 tons/day, which can produce 3859 m3 of biogas per day. On the contrary, for cooking villagers require only 2748 m3 of biogas per day. Moreover, the surplus biogas of 1111 m3 per day can be used to produce electricity of 6666 kWh per day, which can fulfill the demand of about half of the population of villages under study. People are using firewood, cotton stalks, kerosene oil and LPG (Liquefied Petroleum Gas) for cooking. Converting animal dung into the biogas not only reduces the consumption of the traditional fuels used (Firewood, Cotton Stalks, Kerosene Oil and LPG), but also prevents about 900 thousand tons of CO2 emissions into the environment. Additionally, a fixed dome biogas plant of 8-10 m3 size was recommended for each of the houses under study.
