Abstract

Because of the excessive use of fossil fuels and pollution caused by them, global warming and environmental pollution are the most important issues that have led many researchers to research in this field. On the other hand, the depletion of fossil fuels and the increasing demand for energy have led to a energy crisis that has led researchers to find suitable alternative fuels with less environmental impact. Renewable energy sources include solar, wind, geothermal, hydroelectric and biomass energy. Biogas is one of the sources of renewable energy that can be taken with proper management of both energy generation and environmental protection. Biogas derived from digestion of biodegradable agricultural products is an approach to turning the threat into a very suitable opportunity. In this study the residue of 5 medical plant include Glycyrrhiza glabra, Mint, Carum carvil, Lavender and Burdock(deve-dikeni) in the mesophilic temperatures conditions and two pure states and C/N ratio 30 were evaluated. The results were modeled with two logistic and Gampartz models. Based on the results, the highest amount of biogas production was observed in two pure state and C/N ratio 30 conditions is relative to Carum carvil with values of 38872, 13605 ml, respectively. Also, the results of modeling for Glycyrrhiza glabra, Mint and Carum carvil were high accuracy and correlation coefficient with values of 0.99, 0.993 and 0.994 for logistic model and 0.998, 0.9994 and 0.9954 for the Gampartz model.
