Dairy manure is a valuable by-product of the animal production industry, but it may cause environmental problems due to inappropriate management and utilization. Although Elodea canadensisis an invasive species, it can be used as a renewable energy source for production of some biorefinery products such as biogas. Therefore, the potential use of E. canadensisbiomass as a co-substrate for biogas generation was investigated by gradually increasing the amount of E. canadensisin the mixture containing dairy manure. Microalgae collected directly from Lake Eğirdir by hand were first dried and then subjected to grinding. Five different mixtures were prepared for the co-fermentation of E. canadensiswith dairy manure. The experiments were carried out in the anaerobic digester unit, which consists of 2-L bottles in a temperature-controlled water bath. The results showed that the specific methane production of the mixture containing only dairy manure was 192.3 mL CH4/g OM, while that of the mixture containing only E. canadensiswas measured as 151.1 mL/g OM. As a result, the increase in the amount of E. canadensisin the mixture decreased biogas and CH4production. However, this study showed that it is possible to produce biogas from E. canadensis, and an undesirable invasive species in natural water resources can be used as a biomass energy source. |
