Abstract: This article presents the results of the process of biomethanization and joint biodegradation of manure from cows (reference sample), a mixture of the same manure and household waste of fruit-vegetable origin (peelings), as well as a mixture of the manure and bismuth complex of ptoluenesulfonic acid. The samples are incubated at 34.5 degrees Celsius, under nitrogen atmosphere, during 30 days, periodically measuring the volume of biogas and the percentage of methane. From the results obtained, one can see that during entire period of the experiment, the mixture containing cow manure and household waste of fruit-vegetable origin produce the largest amount of biogas, compared to the other two samples. However, regarding the methane content in all samples, its amount in this mixture is the least. During the measurement period, mixture containing the complex [Bi6O6(OH)3](C7H7SO3)3 always show a larger amount of biogas produced, compared to the reference sample. It is notewo
