In the process of accession to the EU, Republic of Serbia will be obliged to achieve an appropriate share of renewable sources in primary energy consumption in addition to control the emission of carbon dioxide in order to comply with EU's energy policy. In this paper the potential of the production of the so called "green electricity" from biomass and waste in Republic of Serbia is shown with particular attention to the Electric Power Industry of Serbia, as the largest potential producer of electricity from renewable fuels. Based both on the available total quantity and heating value of non-hazardous solid waste material (municipal and industrial), the calculation of the total available energy potential of waste in Republic of Serbia (by regions) was performed for the state of the 2010 th and the projections of waste quantity growth until 2020 th . Also, for the same time period, the available amount of waste biomass suitable for (co-)combustion with coal was estimated, as the respective energy potential. The possible energy effects of (co-)combustion in power plants as well as reduced emissions of CO 2 with significant financial impact are demonstrated. Actually, this paper demonstrates necessity and techno-economic justification (co-)combustion of renewable fuel with coal in thermal power plants in Serbia. bustion for energy production. According to available statistics in the EU-27 biomass and waste account for 1/5 in the production of electricity from green sources including the production of hydro power plants [3]. The EU strategy in electricity production from waste and biomass in thermal power plants (TPP) of EU-27 aims to achieve about 11 % up to 2030 and it presents 7 % of total electricity produced (about 4.4 million GWh) [2].Although the available quantities of biomass present very significant potential, the biomass is sporadically used in several power stations in Serbia, but in quantities that have no influence on the energy balance of the country, while firewood is still almost entirely used for households heating on traditional inefficient way. When considering waste materials, which may also represent a significant domestic potential energy, the use of these materials in Serbia does not exist. Also, as in the neighboring countries, there is no organized collection, sorting and recycling of waste materials, besides the paper.This study indicates necessity and techno-economic justification co-firing of renewable fuel with coal in Electric Power Industry of Serbia (EPS) thermal power plants [4], where domestic solid renewable fuels from non-hazardous solid waste materials (municipal and industrial) and biomass wastes for obtaining heat and/or electricity are defined. Also, their quantities and annual potential energy that can be (co-)combustion with coal in EPS power plants up to 2020 were estimated. Radovanovi}, P.

In the process of production of different crop residues that occur in some species exceed three times the amount of crops produced. These residues can be baled and still used. Today in Serbia the producers of baled biomass are mainly farmers who receive biomass in baled form as by-products of primary production. In practice there are two basic types of bales: small square bales (0,40x0,50x0,80 m) and large cylindrical bales (ø1,80x1,20 m) or rectangular shape (0,80-1,20x0,70x1,50-2,50 m). Advantages and disadvantages of specific types of bales are the following [9]. Small conventional bales have many advantages: low cost of presses, binders moderate prices, the need for a smaller tractor, good storage, a favorable agreement on means of transport, simple disintegration and chopping by means of lower prices, the possibility of firing the entire bales and others. Deficiencies are inevitable manual operation, by hand using auxiliary storage means, a relatively high usage of the binder, the lower reliability than other presses etc.

“…Cigar burner combustion system of baled biomass has also been recognized by the European Union as the most suitable method to be utilized for burning baled agricultural residue (Kavalov & Peteves, 2004). For straw combustion cigar burner technology is very appropriate and without any reserves (Mladenovic et al, 2009 …”
