As a result of joint research of employees of the All-Russian Research Institute of Reclaimed Lands and Tver State Technical University, aerobic-anaerobic solid-phase fermentation of a mixture of organic animal waste and hard-to-hydrolyze raw materials of plant origin was developed. Biotransformation of the fermented mixture takes place over several days, and the pasteurization effect is achieved as a result of short-term processing of the fermentation product with ultrasound intensity of 50-60 W/sq.cm. Liquid ani...

Manure is characterized by a complex multicomponent composition and can be considered as a source of nutrients for microorganisms and plants. Moreover, manure has a high level of biogenicity. Therefore, this waste can be considered as the main resource for organic fertilizer production. Currently, there are many technological solutions for processing of renewable animal and poultry waste. Fast solid-phase fermentation of the organic feedstock is a most promising technology. Five technological solutions for the fer...
