Full-scale of composting process of biogas residues from corn stover anaerobic digestion: Physical-chemical, biology parameters and maturity indexes during whole process.

•Corn straw biogas residues is an ideal material for full-scale composting.•The biogas residues get maturity after 80 days of composting.•Temperature and NI was easily and credibly parameters to evaluate maturity.•Anaerolineaceae and Limnochordaceae were the most abundant bacteria.•Chaetomium was the most important fungal to decompose lignocellulose.
