POTENTIAL OF AGRICULTURAL WASTE BIOMASS FOR BIOENERGY PRODUCTION IN POLTAVA REGION

Abstract

Favorable climatic conditions, soil type and water resources have a positive impact on the development and location of agriculture in Ukraine. The structure of the agricultural sector in Ukraine consists of crop and livestock industries that are a powerful source of various types biomass for energy production. At the same time, the assessment of the bioenergy potential of agricultural biomass is relevant in the context of reforming the administrative-territorial distribution in Poltava region. In addition, it is the basis for the calculation and analysis of types, localization and required processing capacity of biomass. Assessment of the bioenergy potential of agricultural biomass provides an opportunity to economical assessment the chain that agricultural producers can potentially occupy in the energy market of Poltava region. Research in the field of renewable energy is actual on international level, especially in the context of the word’s energy crisis. The conducted researches of bioenergy potential of agricultural biomass of Poltava region can become an economic basis for formation regional bioenergy sector at local level. The bioenergy potential of Poltava region was estimated by three indicators: bioenergy potential (MW/year), biogas productivity (million m3 /year), replacement of fossil fuels (thousand tons conditional fuel/year). Assessment of the bioenergy potential of crop production was performed by the following types of crops: cereal and legumes, sunflowers, vegetables. Assessment of the bioenergy potential of livestock was performed by the following types of waste: cattle, pigs and poultry. Thus, the total energy potential in Poltava region was about 8.28 thousand MW / year. The energy potential of crop waste was estimated at the level 7.56 thousand MW / year. The energy potential of livestock waste was 0.72 thousand MW/year. The total replacement of fossil fuels in Poltava region was 3.31 thousand tons conditional fuel/year. Index of replacement of fossil fuels by crop wastes was higher (3208 tons conditional fuel/year) than replacement of fossil fuels by livestock wastes (89 tons conditional fuel/year).
