Determination of commercially available biogas production capacity Tekirdağ and its effects on methane capture in province

This research was carried out in farms which have 100 and more cows with commercial biogas production capacity, in 2019 in Tekirdağ. The enterprises with this size were determined by the data obtained from provincial and district directorates of Agriculture and Forestry. There are 77 enterprises with these characteristics throughout the province. The cattle assets of these enterprises are 23435 units.Total methane production potential and energy value were calculated as 22466 Nm3/ day and 81756.4 MWh / year, respectively. It was determined that 42512,48 MWh/year useful heat energy and in CHP unit 28 614.17 MWh/year electricity energy and 19 784.65 MWh/year additional heat energy could be obtained from methane produced by anaerobic fermentation. It is determined that 19 067,56 tons CO2e/year of methane will be released if the manure is stored outdoors. It was determined that methane emission could be reduced by 1 087.13 tons CO2e/year if the nitrogen was used in fermentation residues instead of the chemical fertilizer. Total methane retention in the use of methane for heat purposes will be 31 590,55 tons CO2e/year. Methane emissions will be reduced by 12 522.99 tons CO2e/year when used for heat purposes, than the conditions in which the manure is stored outdoors. When methane is used in the CHP unit to provide electricity and heat energy, total methane retention is calculated as 38 467.6 tons CO2e/year, and the decrease in methane emission is calculated as 19 400 tons CO2e/year.In the event that the biogas potential of our country is fully utilized, both energy recovery and a significant amount of methane emission will be reduced and environmental contribution will be provided.
