Animal waste utilization technology

Abstract

The applicability of learned introduction of anaerobic digestion of animal waste will be obvious after a wide setting of afull-scale experiment and an across-the-board economic feasibility.However, yet today, basing on the domestic and abroad practice on biopowerdigesters engineering and operation,it can be argued that their use is economically advantageous than the traditional system. The obtained experience evidences thatthe cubicle housingof dairy cows is advanced. Milking operation is carried out in a special house, which ramps up milkquality, improves working conditions for milkmaids, and reduces labor costs.The problem of the animal waste impact on environment, especially on natural waters is acute. There is no summarized information about their distribution for fertilization and discharge.Not only liquid animal waste, but also silage sap causepollution. The Energy Program sets the task of widespread involvement of non-conventional energyin the country's energy balance. Biomass is of the great importance among such sources in the agro-industrial complex of the country.Anaerobicmethanoic digestion of animal waste allows evolving biogas - a valuable organic fertilizer with extra biological activityor protein-vitamin concentrates for feed supplementation.Such digestion of animal waste is an effective environmental action that provides its deodorization, reduction of soil and water pollution with repugnant substances and pathogenic microflora, atmospheric emissions (due to removal).
