Biomass potential is available at the whole territory of the Republic of Serbia. The majority of renewable energy – 13% is biomass, the redundant are solar energy, energy of wind as well as thermal energy. Wood biomass is mostly located in the area of the central and southeast Serbia. Biomass potential (in the form of pellet, briquettes, chips…) is dynamic category and in order to increase it, it is necessary to undertake adequate activities for the use of uncultivated land, and for the use of marginal land in the biomass production for energy sector purposes.
This work presents a theoretical and practical framework for wood biomass market in southeast Serbia. Serbia began to produce wood pellets in 2007 with the opening of one factory in the region of Sumadija. In 2008 production continued to develop with 3 more factories opened. In 2013 the number of companies increased when 17 were opened which represents the best year for investment of pellet plants in Serbia.
Cost of production of briquettes and pellets depend on following factors: row materials, methods of collecting, collection techniques, transport and storage, lines for molding, extrusion technology, packaging, performance line, the number of workers, the value of the facility and equipment, interest on loans, etc. When everything is taken into account the cost of production of briquettes and pellets from wood is 100 €/t, the selling price of briquettes and pellets in bulk and wholesale amounts 150 €/t packed in sacks, on the domestic market.
Expansion of production capacities and the number of companies was the largest in the production of wood pellets during the last five years. Beside the relatively high number of producers, the second important characteristic of production of wood fuels is the fact that their production in southeast Serbia ranges from traditional to contemporary way of production, i.e. that traditional and modern technologies are used in their production. Furthermore, the number of companies with traditional way of production is much higher than those in which wood fuels are produced by contemporary technologies.
