Utilization of agricultural and forest biomass for energy – an economic potential evaluation in Croatian counties

The aim of this study was to estimate the viable quantities for different types of biomass in Croatian counties and cost of biomass at the power plant location. Energy potential for biomass in Croatian counties was calculated for wheat straw, corn stover and for forest residual, since those are considered economically viable at the moment. Methodology used for calculating potential of forest residual is based on assumption that 12% of the total mass of tree is forest residual which can be removed from forest and used in energy purpose. Methodology used for estimating removable residual from wheat straw is based on minimum requirements for soil protection, animal feeding and bedding. For estimating removable potential of corn is used assumption of 20% for calculating fraction on the field that go uncollected and 50% for calculating amount of corn stover for soil protection. Potential of wood waste from wood industries in this study is not calculated because these residuals wood industries are using it for own consumption. Costs of different types of biomass at the plant location are calculated in depending of transport cost, size of power plant and radius of collecting biomass. Results of this study indicate that the energy potential of forest residual is 5.9 PJ ; wheat straw is 7.9 PJ and for corn stover energy potential is 4.4 PJ.
