The aim of the present study is to compare the results obtained from the simulation with the experimental values. The simulated results showed a good fit for cumulative produced methane gas volume and the concentration profile of total volatile fatty acids (VFAs).324202132420211820https://www.naun.org/main/NAUN/energyenvironment/2021/a062011-003(2021).pdf10.46300/91012.2021.15.3https://www.naun.org/main/NAUN/energyenvironment/2021/a062011-003(2021).pdf10.1016/s0960-8524(00)00023-7J.
