While energy sources are now commonly found in systems that work on fossil fuels, they have begun to relocate to alternative and renewable sources of energy, especially due to the growing population, the risk of exhaustion of fossil fuels, and the damage they have caused to the environment. Biogas, which has an important potential among renewable energy sources in Turkey, is a mixture of organic-based wastes, resulting from the disintegration of an anaerobic fermentation system in an anaerobic environment, with combustible methane gas. In this study, the biomass potential of the wastewater of the dairy industry was measured and 410 ml biogas were produced in 35 days and the experimental results of the biogas production were digitized by creating a curve. Various polynomial equations are applied to the data set at different grades. The fifth order polynomial equation is the best fit. The equation was obtained as y = 0.98 x. The SSE, RMSE and the discriminant coefficient were determined as 3130, 9.89 and 0.99, respectively.
