This article discusses a new method of utilizing carbon-containing waste into biogas with the addition of a biological active additive Mefosfon to the substrate in order to accelerate the process of obtaining biogas and preserve nutrients in the final product - organic fertilizer. The experiments were carried out in a small-volume biogas plant (MBU) without air access in a heat-insulated reactor filled to 2/3. The results of numerical studies of the conversion products of cattle manure are presented. The manure was kept in the reactor for 7 days. The use of the drug Mefosfon in ultra-low concentrations (10-4) made it possible to obtain a useful product in the form of high-quality organic biofertilizers and biogas. The conducted microbiological analysis of the experiments showed that in the experiment with the use of the drug Mefosfon, the content of enterococci and bacteria of the Escherichia coli group were lower than in the experiment without the drug Mefosfon. Bioconversion of the organic component of the substrate allows the use of waste in agriculture as organic fertilizers. Such processing can significantly reduce the dry weight of the treated organic waste and reduce the content of pathogenic microorganisms Salmonella spp. and Enterococcus spp., bacteriophage FX174, Ascarissuumova. Mefosfon reduces the time of maturation and neutralization of carbon-containing agricultural waste, which indicates the prospects of its use. After processing waste in a small-volume biogas plant, there are no pathogenic pathogenic microflora, helminth eggs, weed seeds, nitrites and nitrates. The final nitrogen content of the Mephosphon treated substrate is higher than that of the untreated substrate. The acidity values in the substrate pH 6.7 in the untreated and 7.5 in the treated substrate. Studies have shown that when the drug Mefosfon is added to the substrate, the release of biogas begins on 1-2 days and lasts up to 7 days. In this case, the biogas yield increases up to 25% compared to the use of the control substrate without the use of the Mefosfon preparation. The drug has found application in plant growing, animal husbandry, reclamation of contaminated soils
