In this study, anaerobic co-digestion of grass, cow manure and sludge was studied under mesophilic conditions for 65 days. Experiments were performed on a feed ratio of grass/manure from 5 to 25%, respectively. The maximum cumulative biogas and methane yield was obtained as 331.75 mLbiogas/gVS and 206.64 mLCH(4)/gVS for 25% ratio. Also, the results of the experiments were tested on the three different kinetics model which are the first order kinetic model, modified Gompertz model and Logistics model. As a result of the study, it was found that by using grass nearly 480 x 10(6) kWh/year electricity may be produced and 0.5 x 10(6) tons/year CO2 greenhouse gas emission mitigation may be reached.eninfo:eu-repo/semantics/openAccessPretreatmentScience & technologyMultidisciplinary sciencesScience & technology - other topicsArticle00098536070002913110.1038/s41598-023-33169-0
