Noted the potential use of sustainable bioenergy in the the European Union. In Ukraine, one of the outstanding issues of implementation of biogas plants is that the average length of stay of raw materials in the reactor ranges from 30 to 55 days, which complicates the possibility of their mass implementation. Application of enzymes in technology biomineral fertilizer is a new scientific direction. It is shown that the addition of whey in optimum ratio of 1:30, you can reduce the length of stay of raw materials in the reactor anaerobic digestion of 1,5 times. Analyzed chemical composition of fermented biomineral fertilizers, it is determined that the contents of carbon (C) it is 41,8%, Ntot. – 5,2%; CaО – 13,8%; K2O – 12,2%; P2O5 – 11,5% in terms of dry substance. It is established that the maximum affinity of the enzyme to the substrate occurs on the 11 day of fermentation. The technological scheme of production of mineral fertilizers from wastes using enzymatic additives.
