Zusammenfassung:•C/N optimization from co-digestion of the WS and CM.•85.11% methane enhancement at C/N value of 20:1.•65% reduction in C/N ratio due to pre-treatment of WS.•CODs removal of 53.24% from the waste activated sludge. The present study emphasized the co-digestion of the thermal-H2O2 pretreated wheat straw (WS) and chicken manure (CM) with the waste activated sludge at four levels of C/N (35:1, 30:1, 25:1 and 20:1). All C/N compositions were found significant (P
