Kinetic study was conducted for the biogas production from Napier grass and distillery wastewater. The experimental outcomes of batch reactors were fitted into modified Gompertz (MGM), modified Richards (MRM), and Logistics function (LF) kinetic models. Based on the results, MGM and MRM were found to be the best fit for biogas production from the anaerobic mono- and co-digestion of DWW and NG under specific conditions. Reactors R4 and R5, indicated a negative lag phase (λ), suggesting that biogas production commenced immediately on the first day and the respective systems are conducive to the survival of microorganisms. The maximum biogas potential (A) of the batches followed the order R2 < R1 < R3 < R4 < R5 while the maximum biogas production rate (Rm) of the batches in ascending order is R2 < R1 < R3 < R4 < R5.
