ANALYSIS OF PELLETS AND BRIQUETTES PRODUCTION FROM CORN RESIDUES IN UKRAINE
The purpose of the study is to analyze the technical and economic basis for the development of the production of pellets and briquettes from by-products of grain corn in Ukraine. The objective of the work is to determine conditions that ensure feasibility of projects of this type in Ukraine. Results of estimation of energy potential of by-products of corn grain in Ukraine are presented. The country has a large potential for this type of biomass available for biofuels and energy production. Current trends in agricultural development indicate that this potential may even increase in the future. For Ukraine’s conditions, it is recommended to harvest by-products of grain corn in the form of rectangular bales with the use of a three-pass harvesting system. Fuel characteristics of corn stover are considered. In general, biomass of this type has fairly good fuel properties close to those of wood fuels. Due to this, biofuels made from corn stover can be burned in boiler equipment intended for wood biomass. The effective use of grain corn by-products is the production of briquettes and pellets. Under current conditions, a simple payback period for such business projects can be up to 4…5 years with the internal return rate of more than 22%. The biggest impact on the main economic indicators of the projects is made by the sale price of solid biofuels, the productivity of the equipment, as well as the price of raw material.
