The biotechnological complex is a closed waste-free environmentally safe enterprise, which ensures the quality of the environment in accordance with the current environmental legislation, the complete utilization of fecal effluents and obtaining on their basis of biohumus, biologically effective organic fertilizers, feed additives for animals and poultry, electricity and heat. At the same time, the company implements a closed-loop circulating demineralized water supply. The treated wastewater is sent to bio ponds, irrigation, greenhouses, and for own needs of farms of cattle. The proposed development of biotechnological complexes for processing of organic waste can provide agricultural and urban utilities with additional renewable sources of electricity and heat for their own needs, and for the implementation of other enterprises and the public.
