A review of the current state of the theory and practice of bioenergy production from waste allowed us to identify the scientific and applied problem of substantiating the rational configuration of a modular anaerobic bioenergy system, taking into account the volume of organic waste generated in settlements. To solve this problem, this paper develops an approach and an algorithm for matching the configuration of a modular anaerobic bioenergy production system with the amount of organic waste generated in residential areas. Unlike the existing tools, this takes into account the peculiarities of residential areas, which is the basis for accurate forecasting of organic waste generation and, accordingly, determining the configuration of the bioenergy production system. In addition, for each of the scenarios, the anaerobic digestion process is modeled, which allows us to determine the functional indicators that underlie the determination of a rational configuration in terms of cost and environmental performance. Based on the use of the developed tools for the production conditions of the Golosko residential area, Lviv (Ukraine), possible scenarios for the installation of modular anaerobic bioenergy production systems are substantiated. It was found that the greatest annual benefits are obtained from the processing of mixed food and yard waste. The payback period of investments in modular anaerobic bioenergy production systems for given conditions of a residential area largely depends on their configuration and ranges from 3.3 to 8.4 years, which differ from each other by 2.5 times. This indicates that the developed toolkit is of practical value, as it allows the coordination of the rational configuration of modular anaerobic bioenergy production systems with real production conditions. In the future, it is recommended to use the proposed decision support system to model the use of biomass as an energy resource in residential areas, which ensures the determination of the rational configuration of a modular anaerobic bioenergy production system for given conditions.

At the beginning of the third Millennium, humanity is forced to face a new surge of tensions and contradictions between different countries and peoples, between different parties and faiths, as well as the growth of environmental, economic and social problems both in different regions of the world and on a global scale. These phenomena are the result of the exhaustion of socio-economic forms of development of society within the existing natural resource and environmental conditions. An increasing number of people and states are experiencing an acute shortage not only in quality food, but also in quality water, clean air, energy, land, biological and other resources. After all, according to some scientists over the past hundred years, the consumption of natural resources by mankind has increased almost 100 times. For the first time in the history of mankind, resource and environmental crises have reached the biosphere borders and there is a danger to the existence of civilization. Humanity faces a global challenge, the correct solution of which will result on the lives of our descendants in the future. The common task for all is to preserve the biosphere as the habitat of mankind. Further increase of material and energy flows becomes impossible, as well as further satisfaction of the needs of new billions of people who will be added to the total population. Humanity is on the threshold of a new socio-economic formation, as neither a centrally managed economy nor a market economy has been able to solve the global environmental problems of our planet.
