Every year, the environmental situation in the world worsens, and this primarily concerns soil pollution. With the aim of revitalizing soils, increasing their fertility and stability, world science and practice are turning to the use of biohumus - a product of the vital activity of earthworms.
The energy efficiency of the processes of energy conversion during the utilization of organic matter from animal husbandry complexes into protein feed and biohumus in an agrotechnical structure of protected soil, which makes it possible to obtain valuable products for the national economy all year round, was studied.
The components of the energy balance equation of worm products were studied and the degree of their influence on the bioenergy efficiency coefficient was determined.
To ensure optimal parameters of the microclimate in the vermiculture room, a quantitative assessment of the parameters of the temperature and humidity regime is necessary. It is possible to solve this problem on the basis of the heat balance equation, which was built for the most severe temperature conditions of the worm farm.
It is possible to significantly reduce electricity consumption with the help of various means of retaining heat in vermiculture structures: straw mats, polyethylene and foam coatings.
The power ratio of the heating elements of the substrate and the wind has a significant impact on the energy efficiency of the vermiculture system. Therefore, the temperature of the substrate is set by the technological parameters of breeding worms and must be maintained at a constant level. The air temperature in the worm farm depends on the environmental conditions.
Key words: vermicultivation, energy consumption, livestock wastes
