This study investigated the development and simulation of CSTR for biogas production from municipal solid waste. The factors affecting biogas production studied were pH, retention time and organic loading rate. Optimization of the parameters were done using Minitab and desirability optimization function shows that percentage error between predicted optimal responses and actual optimal responses is less than 2%, making the desirability function adequate in optimizing the factors affecting the yield of biogas from MSW. Under the process of continuous stirring of the Bio-digester tank and optimization of the process conditions, the digestion of the substrates subjected at different process parameters with these conditions averagely gave biogas yield of 67.588mL biogas/mg. This showed an increase in the production of Bio-gas.
