Development of the planning model for central biogas plants in Isparta province using the mixed-integer programming

The use and diversification of renewable energy sources is one of the issues that have an important place in the energy policies of countries. Due to the decrease in fossil resources and negative effects of fuels obtained from these resources on the environment lead the world today to conduct studies and research on renewable and sustainable energy resources. Biogas and electrical energy production using plant and animal wastes is known and utilized as an important alternative for renewable and sustainable energy sources. Within the scope of this master's thesis, biogas and electrical energy capacity that can be produced by using the waste of bovine in Isparta province was determined and investment and transportation costs calculations were calculated accordingly. In order to make these calculations, a planning model for regional central biogas plants was developed by employing mixed-integer programming method. Lingo package program was used for the analysis of the planning model. According to the planning model outputs; It was determined that 42.636.755 m3 biogas and 77.994,58 MW electrical energy production is possible in Isparta region with the use of 1.063.400 tons of waste to be obtained from the bovine. In order to utilize these animal wastes, it was determined that 8 plants with an annual waste treatment capacity of 58.400, 105.000 and 150.000 tons should be established in various districts of Isparta region. The investment cost required for the installation of these facilities was calculated as 228.085.650 TL and the investment recovery period as 4,81 years.
