Abstract

The current practice on local poultry farms is that the manure from the poultry farms is hardly ever recycled, resulting in soil, water, and air pollution in the vicinity of the factory. One of such poultry farms is located directly in the zone of the Aktobe city near residential areas, which leads to pollution of soil, water, and air nearby to the territory and worsening living conditions of the city residents. The stench is a constant problem in these places.  Therefore, there is urgent need for environmentally and economically sustainable technologies. The creation of effective fertilizers based on the poultry litter may be the most appropriate solution. On the one hand it would solve the problem of the difficult ecological condition of areas with poultry farms. On the other hand, it would solve the problem of a catastrophic decrease in the fertility of soils used in agriculture. As a result of the analysis of existing techniques for processing poultry manure, the authors propose a method of intensive composting of poultry litter by pumping air for the organic and organic-chemical fertilizers production.

The method implements the processes of drying, disinfection, aerobic fermentation, and granulation of enriched poultry litter.
