Abstract :
The present study was designed to investigate the capability of algae biomass to increase
methane biogas production from anaerobic digestion of municipal solid waste. Batch anaerobic digester was
used for digesting the mixture of algae and organic fraction of municipal solid waste (OFMSW). A variety
condition of algae to organic fraction municipal solid waste mixing ratio, pH, temperature, and total solid are
studied for a period of 12 days. It was observed that maximum methane biogas production was found to be
946.0012 mL/gm v.s at optimum condition of mixing ratio of algae to OFMSW were, 1:2, temperature, total
solid and pH of 32 oC, 8 % and 7.5 respectively. Multiple correlation methodology optimized the methane
production with a correlation coefficient (R2) to be 0.925. The first order kinetic model was used to assess the
dynamics of the biodegradation process. The obtained negative value of (k = - 0.2543), indicates that the solid
waste biodegradation was quick with a correlation coefficient (R2) of 0.9906. The Gompertz model was used
to adequately describe the experimental cumulative methane biogas production from lab scale anaerobic
digesters. The theoretical methane biogas yield was found to be 1016.76 mL/gm v.s wh
