Biomethane production from maize and liquid cow manure - Effect of share of maize, post-methanation potential and digestate characteristics

► Co-digestion of cow manure and maize was studied in different share of maize. ► The highest methane yield was achieved, when share of maize was 40% VS of feed. ► Post-methanation potential was low, when methane yield from reactor was high. ► Trace elements content decreased in digestate when the share of maize increased.
