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...
