ABSTRACT
The necessity of developing the production of biogas and digestate at Ukrainian sugar factories focused on the further sale of biomethane in the energy market and for its own needs is substantiated, which will partially ensure the energy security of the state under martial law. The volumes of sugar beet cultivation are determined, and the potential volumes of biogas production from the waste of Ukrainian agro-industrial complexes are investigated. A model of the functioning of a production bioenergy cluster based on a sugar factory has been developed and proposed.
As a result of the study, it was found that a tangible way to increase the level of energy autonomy of the processing industry of the agro-industrial complex of Ukraine is the production of biogas by anaerobic digestion and its subsequent purification to the state of biomethane. To produce this type of biofuel, the use by-products of agriculture, agro-industrial processing enterprises, and organic waste from territorial communities where sugar factories are located is advisable. At the same time, as the analysis of resource potential shows, modern methane generation technologies allow using a wide range of biomass as a raw material base, which can be obtained both from production activities (non-core (non-target) products) and from household waste in general, which is one of the methods of solving the problems of their utilization.
It has been determined that the use of advanced technologies for the transportation of liquid digestate and its injection will reduce the cost of application, increase the absorption in the soil, and the use of biodiesel will reduce transportation costs.

Produkcja biogazu i pofermentu w cukrowniach jako sposób na zapewnienie bezpieczeństwa energetycznego i żywnościowego Ukrainy

W artykule uzasadniono konieczność rozwoju produkcji biogazu i pofermentu w ukraińskich cukrowniach, ukierunkowanej na dalszą sprzedaż biometanu na rynku energetycznym i na własne potrzeby, co częściowo zapewni bezpieczeństwo energetyczne państwa w stanie wojennym. Określono wielkość uprawy buraków cukrowych i zbadano potencjalne wielkości produkcji biogazu z odpadów ukraińskich kompleksów rolno-przemysłowych. Opracowano i zaproponowano model funkcjonowania produkcyjnego klastra bioenergetycznego opartego na cukrowni.
W wyniku badań stwierdzono, że konkretnym sposobem na zwiększenie poziomu autonomii energetycznej przemysłu przetwórczego kompleksu rolno-przemysłowego Ukrainy jest produkcja biogazu w procesie fermentacji beztlenowej i jego późniejsze oczyszczanie do stanu biometanu. Do produkcji tego rodzaju biopaliwa wskazane jest wykorzystanie produktów ubocznych rolnictwa, przedsiębiorstw przetwórstwa rolno-przemysłowego oraz odpadów organicznych ze społeczności terytorialnych, w których zlokalizowane są cukrownie. Jednocześnie, jak pokazuje analiza potencjału zasobów, nowoczesne technologie wytwarzania metanu pozwalają na wykorzystanie szerokiej gamy biomasy jako bazy surowcowej, którą można pozyskać zarówno z działalności produkcyjnej (produkty niezwiązane z podstawową działalnością), jak i ogólnie z odpadów z gospodarstw domowych, co jest jedną z metod rozwiązywania problemów związanych z ich utylizacją.
Ustalono, że zastosowanie zaawansowanych technologii transportu płynnego pofermentu i jego wtrysku obniży koszty aplikacji, zwiększy absorpcję w glebie, a zastosowanie biodiesla obniży koszty transportu.
