Evaluation of methane production and macronutrient degradation in the anaerobic co-digestion of algae biomass residue and lipid waste

► Co-digestion of algae biomass residue (ABR) and fat, oil, and grease (FOG). ► Co-digestion of ABR and FOG improved methane yield and methane content. ► Co-digestion allows higher organic loading rate in continuous AD process. ► Carbohydrate and protein reductions are not affected significantly by co-digestion. ► Co-digestion enhances lipid degradation at increased organic loading rate.
