Recently the demand for fossil fuel has grown significantly with the rapid development of the Chinese economy. Renewable energy was developed to replace traditional fossil fuels, which would decrease the greenhouse gas emissions and reduce air pollution caused by fossil fuel combustion (Shen et al., 2010). Micro-algae are well-suited biomass resources because of their relatively high lipid, starch, and protein contents, as well as the lack of lignin. According to their carbon and nitrogen compositions, the co-digestion of algal and lignocellulosic biomass is an effective way to improve the conversion efficiency and methane yield in anaerobic digesters (Zhong et al., 2012). Recently, it has been demonstrated that iron oxides could accelerate the anaerobic conversion of organic biomass, such as aquatic plant, and algal biomass (Ma et al., 2015). However, it is still not clear whether the methane production yield and substrate degradation efficiency could be further enhanced in the anaerobic co-digestion process with the addition of iron oxide. So, in the current study effect of goethite on the anaerobic co-digestion of lignocellulosic and algal biomass feedstocks was investigated.
