We developed the scientific basis of solid food waste utilization using biotechnologies that utilize the metabolism regulation of microorganisms-destructors. We identified that mass transfer intensity in cultivator determines technological characteristics of food wastes destruction. The comparative analysis of these characteristics in our modified cultivators (mechanic shaking, impulse hydraulic shaking and without shaking) showed that the most efficient is food wastes destruction with hydraulic shaking: destruction coefficient increased four times, time of destruction decreased almost two times.  Complex tests of pilot plant were conducted by us. We identified that almost complete destruction of food wastes is achieved in 9 days, when using impulse hydraulic shaken cultivator along with microorganisms-destructors metabolism regulating biotechnology. Besides, biogas, including hydrogen (61%) and methane (35%) had been emitting in this process. This makes this biotechnology useful both for solid food waste neutralization and biogas extraction.
