Abstract
Based on the performed analysis of the state of theory and practice, the expediency of assessing the relationships between the functional indicators of the bioenergy production system from the organic waste of residential areas is substantiated in the projects «European Green Deal». It is based on the use of existing results published in scientific works, as well as on the use of methods of system analysis and mathematical modeling. The proposed approach avoids limitations associated with the one-sidedness of sources or subjectivity of data and also ensures complete consideration of various factors affecting the functional indicators of the bioenergy production system from the organic waste of residential areas. Four types of organic waste generated on the territory of residential areas are considered. The results indicate the presence of dependencies with close correlations. The resulting dependencies can be used to optimize processes and increase the efficiency of bioenergy production. It was found that:
- Yard waste has the highest volume of total volume of solid organic substances, but a low yield of biogas and share of methane production;
- Food waste has the highest yield of biogas and, accordingly, the share of methane production;
- Mixed organic waste has the lowest volume of total volume of solid organic substances and the lowest content of content of volatile organic substances. The amount of electricity and thermal energy production varies by type of organic waste, with mixed organic waste having a higher average amount of electricity production compared to other types of waste.
It was established that the production volume of the solid fraction (biofertilizer) is also different for different types of organic waste. Less solid fraction is produced from food waste than from yard waste. The obtained research results are of practical importance for the devel-opment of sustainable bioenergy production from organic waste in residential areas during the implementation of the European Green Deal projects. They provide further research on the de-velopment of effective models for determining the rational configuration of bioenergy produc-tion systems from organic waste for given characteristics of residential areas.
