In order to increase the efficiency of composting the organic
component of solid municipal waste as a highly effective biotechnological method, and
to compare the characteristics of the processes, it is suggested to use soil as an
inoculum, as a microbiological additive - an extract from the soil.
The article presents the results of the study of the soil microbiocenosis
qualitative and quantitative composition in order to use it as an inoculum in the process
of composting the organic part of solid municipal waste. The influence of
microbiological additive on the process of the organic waste composting for
acceleration in mesophilic and thermophilic temperature regimes with controlled
parameters was studied.
The results of the conducted studies allow us to conclude that the organic waste
composting with the microbiological additive is appropriate, both in the case of
thermophilic and in the case of mesophilic regimes. The period of the compost
maturation with the use of a microbiological additive is 6 weeks. It was shown that the
microbiological complex accelerates the process of composting the organic component
of solid municipal waste by 3.3 times for the thermophilic regime and by 2.1 times for
the mesophilic conditions of composting process, which testifies to the efficiency of its
use in the operation of the solid municipal waste processing in order to improve the
general level of environmental safety.
