Development of biomass potential of by-products of agricultural crops in the agrarian sector of economy

The purpose of the article is to improve methodological approaches to assessing energy potential of different types of biomass in Ukraine, and to consider possibilities of its implementation and reducing import dependence on traditional types of energy resources. Research methods. In the research process the following methods were used: induction and deduction, which made it possible to indicate and deepen justification of the expediency for using biomass types that do not create contradictions with food provision; the systematic approach for consistent assessment of economic energy potential of specific types of biomass; analysis and synthesis and grouping, which allowed to make an optimal distribution of straw biomass for needs; graphical, tabular, and comparison method, which allowed to reveal spatial and temporal peculiarities for biomass formation by agricultural origin; abstractlogical, statistical, calculation-constructive, correlation-regression analysis, etc. Research results. There was made an estimation of economic energy potential of biomass in agricultural enterprises, obtained as a result of trimming of fruit trees and grapes, waste as a result of wood processing, industrial processing of agricultural raw materials, straw and vegetable wastes; the estimation made it possible to determine general opportunities for the agricultural sector in providing energy without creating threats to the state food security. Elements of scientific novelty. It was proposed methodical approach to optimal distribution of cereal by-products, in particular straw, for fertilizer needs, littering animals and bioenergy production. Complex approach was proposed and on its basis was made calculation of total economic and energy potential of biomass obtained in agriculture without creating threats to the state food security. Practical significance. Estimation of the total economic energy potential of biomass in the agrarian sector in Ukraine in general, as well as by regions, was carried out. In addition, detailed calculations were carried out in context of separate sources of biomass production that are not main agricultural products. Tabl.: 9. Figs.: 4. Refs.: 21.
