EVALUATION OF THE EFFICIENCY OF ODOR REMOVAL DURING THE DECOMPOSITION OF FISH WASTE FRACTIONS WITH THE USE OF MICROORGANISMS

The composition of emissions generated during the decomposition of protein and lipid fractions of fish waste has been studied, and the ratio of highly volatile organic compounds (VOCs) in them has been determined. It has been shown that the emissions at the first stage of composting contain 8 classes of VOCs, including those with a strong odor. The effectiveness of the experimental biological preparation has been assessed. The importance of modifying the mechanism of action of the biological preparation, as well as further research in this area, was noted. The method for identifying highly volatile compounds concentrated on the sorbent was proposed.
