A theoretical analysis of the impact of maize silage in milky wax maturity added as a co-ferment in slurry biomass for biogas production was conducted. Several alternative cattle slurry to maize silage ratios were studied. Regression equations were derived to determine how biogas production and potential energy rating - for cogeneration modules vary in biomass with different relative content of maize silage. The addition of maize silage in the form of coferments in the slurry biomass has a positive impact on the biogas production and its relevant energy parameters - total structural heat and electric power. The methodology can be used in the practice to estimate the energy potential of slurry biomass in combination with a certain amount of maize silage The findings of the analysis are of purely practical nature for good practices in biogas production in Bulgaria.
