Collection and logistics of agro-biomass (straw) In many cases straw is still burned on the fields even it is prohibited by law DKTI Bioenergy Serbia Belgrade, 19.02.2014 9
Collection and logistics of agro-biomass (straw) Straw collection and logistic usually done with old tractors and balers by local farmers Straw sold to local companies for heating and drying of cereals Straw and corn cobs collected by farmers for household and farm heating DKTI Bioenergy Serbia Belgrade, 19.02.2014 10
Collection and logistics of agro-biomass (straw) But also professional straw collection and logistic companies already present on market Pictures below show straw collection and storage by company “ Hollo Farm” in Dorodoslovo DKTI Bioenergy Serbia Belgrade, 19.02.2014 11

Identified agro-biomass (straw) heating plants CHP-plants fired with agro-biomass NOT identified Status of implementation of heating plants in Province of Vojvodina can be characterised for mainly three categories: 1. Small-scaled and old firing systems manufactured by local boiler producers in the past 2. Scientific and research plants at smaller scale 3. Newly invested plants for heating and process heat with advanced technology DKTI Bioenergy Serbia Belgrade, 19.02.2014 13
Identified agro-biomass (straw) heating plants - Examples 1. Small-scaled and old firing systems manufactured by local boiler producers in the past 2 x 250 kW heating boiler (25 years old) fired with soya straw used by agricultural cooperative “ Mladiborac ” in Municipality of Apatin for drying of cereals and farm heating Boilers manufactured by old train wagon factory in Subotica (shut down) Assumption that some similar boilers are used in Province of Vojvodina 2. Scientific and research plants at small scale Research heating plant installed at PKB premises near Belgrade The heating plant is fired by soya straw for supplying thermal energy to green houses Project managed by the Innovation Center, Faculty of Mechanical Engineering, Belgrade University, Associate of Nuclear Institute Vinca - Laboratory for Thermal Engineering and Energy DKTI Bioenergy Serbia Belgrade, 19.02.2014 14
Identified agro-biomass (straw) heating plants - Examples 3. Newly invested plants for heating and process heat with advanced technology 3.1. Sremska Mitrovica: 18 MW heating plant connected to district heating Fired with sunflower shells In the ownership of Serbian state-owned power producer Elektroprivreda Srbije (EPS) and operated by regional arm Panonske Termoelektrane-Toplane 3.2. Victoria Group Company in recent years installed a capacity of around 40 MW thermal Heating plants fired by different agro-biomass fuels Thermal energy used in processing plants of company group 3.3. JKP Suboticka Toplana (project in development) District heating company of the City of Subotica plans to invest in biomass CHP-plant with capacity of 5,0 MW el and 9,2 MW th Project supported by KfW DKTI Bioenergy Serbia Belgrade, 19.02.2014 15
Identified agro-pellets producer 1. Pellet Plant Dorodoslovo d.o.o. Capacity of the factory is 100.000 tons of agro-pellets per year from corn straw Corn straw bales are produced by “ Hollo Farm” located in Dorodoslovo 2. Small-scaled agro-pellets and briquetts producers Several small-scaled agro-pellets producers exist on market Due to lack of standardisation and weak local market sector does not develop very well DKTI Bioenergy Serbia Belgrade, 19.02.2014 16
Identified biogas plant in City of Vrbas Biomass plant in the ownership of Mirotin Energo d.o.o. 1 MW el in operation; expansion of 0,5 MW el in preparation Fuel basis: 27.000 tons cattle manure 10.000 tons corn silage Residues from sugar beet and green waste DKTI Bioenergy Serbia Belgrade, 19.02.2014 17
Serbian Energy law and feed-in tariff for biomass The energy policy of Serbia is defined by the Energy Law considering the promotion of using renewable energy sources. On 20.11.2009 feed-in tariffs for renewable energy had been adopted. The provisions entered in to force on 1.1.2010. Amendments to the feed-in tariffs are expected for next periods. The feed-in tariff for biomass is shown in the table below Installed capacity in MW Tariff c € /1kWh until 1 MW 13,26 13,82 – 0,56*R from 1 MW up to 10 MW (R = installed capacity) Over 10 MW 8,22 DKTI Bioenergy Serbia Belgrade, 19.02.2014 18
