In the current work, the process of fermentative conversion of animal waste and non-hydrolized plant materials (peat) using food waste and ascorbic acid salts as a stimulants is described. The amino acid composition of the biofermentation products was estimated. The possibility of the target biosynthesis for the production of fertilizers and feed additives with the pre-determined properties was recognized. It was shown that the additive of bread making waste with the concentration of 10 wt. % increases the amino a...

In this work, we propose technology for processing protein-containing products - beans into protein components for nutrition, also the use of waste after protein in the energy industry. The technology includes several stages: extraction, separation of fractions, precipitation, concentration. The optimal conditions for each stage of the technological process were selected (the ratio of the sample to the extracting substance, pH, water module, volume of precipitant, the volume of washing fractions, drying conditions...

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...
