A meta-analysis of iron-based additives on enhancements of biogas yields during anaerobic digestion of organic wastes

The profitability of biogas industries largely depends on substrate biodegradability. Most of the substrates for sustainable energy recovery via anaerobic digestion like lignocellulosic materials contains complex polymeric substances and requires some enhancements to achieve optimum biodegradability. Previous studies have reported that the use of iron additives improved both degradability of such substrates and biogas yield, but iron-based...
