•Synergistic effects were found in CS:CM ratios of 3:1 and 1:1.•In W-AD and HSS-AD, highest methane yields were obtained at CS:CM ratio of 3:1.•Highest volumetric productivity of 14.2L/L was found in SS-AD at CS:CM of 1:1.•VFA/TA value of 0.4 was a more important criterion than NH3-N or FA concentra...
