In Task 1 need to do a detailed analysis biomass resources and potential as follows: Provide an estimation of potential amount (quantity) of biomass available from forest, wood industry, agriculture and food industry, which can be used for energy purposes and disaggregate per ownership type that do not have damaging consequences for the environment; Provide an estimation of thermo-energy potentials of actual biomass potentials and energy crops (including environment impact aspects). Define dynamics and form of collecting biomass; Propose location and storage methods for collected biomass; Provide range of options for biomass utilization for energy purposes; Make a list of potential suppliers of biomass boiler installations in accordance with the continuity of biomass production (type and quantity of biomass that can be produced), included transportation costs and new environmental degradation. 1.1. Analysis of available biomass resources in the municipality of Žagubica and quantitative aspects of thermal energy that can be used for energy purposes Ţagubica municipality is located in Eastern Serbia in southern parts of Braničevo district. Homolje and Ţagubica municipality represent a small geographical area in Eastern Serbia, clearly confined on all sides by mountain ranges. Homolje Mountains (940 m) separate it from Zviţd in the north, Beljanice range (1336 m) separates it from Resava in the south, Crni Vlah massif (1027 m) separates it from Crna Reka basin in the east and Gornjak Mountains (825 m) separate it from Lower Mlava plain river in the west. This represents a geomorphological entity, consisted of two parts: Ţagubica pit in the east and Krepoljinsko– Krupajska pit in the west.
