Presentation Transcript

  1. Miscanthus x giganteus: Perspective and energy potential in Republic of Croatia Nikola Bilandžija, Ph.D. University of Zagreb Faculty of Agriculture ADRIATIC WOOD DAYS, DUBROVNIK 2015.

  2. Global challenges • Energy scenarios: • reduction of unsustainable, • energy reserve resources, • constant increase of fossil fuel prices. • Energy aspirations: • safe, sustainable and continuous energy supply. • Enviromental challenges: • global warming issue, • contamination of soil, water and atmosphere. • Political challenges: • directives, regulations, strategies.

  3. Consuption of renewable energy in EU (AEBIOM, 2013)

  4. Agriculture biomass • cropproduction (hay, straw, stalks, cornstalks, cobs, husksfieldcrops), • vegetablecropsandornamentalhorticulture (wastefromparksandgardens), • grapeandfriutproduction (prunedresidues), • agriculturalproductsfromprocessingindustry (grapemarc, olivemarc, frutspits, frutsshells), • livestockproduction (manure, slaughterhousewaste, fisherieswaste, meat - bone meal), • energycropsfromspeciallyformedstands (Miscantussp., Arundodonax, Sudanniangrass…).

  5. Agricultural energy crops

  6. x Miscanthus sacchariflorus Miscanthussinensis Diploid 2n=2x=38 Tetraploid 2n=4x=74 Miscanthusx giganteus Triploid 2n=3x=57

  7. perennialgrass possibilaty for cultivation on lower quality soil and in different climatic – geografical areas (7,5 - 17,5 °C, 500-1000 mm; to altitude 3000 m) high yield (10-20 and more t d.m./ha), with harvest time from November till March, Aprile Why Miscanthus x giganteus?

  8. Why Miscanthus x giganteus? soil tillage only in the first year of cultivation, cultivation - common agricultural mechanization, excellent resistance to desieses and pests, application of herbicides (first and second year), low fertilization requaiments, high heating value (17,7 MJ kg-1 do 18,8 MJ kg-1) CO2 neutral raw material (LCA-standard: saving 75-93% CO2), phytoremediation of contaminated soils, increases soil fertility, positive impact on biodiversity, decreases erosion.

  9. Plantingmaterial Rhizome Micropropagation plants

  10. Possibilitiesofutilisation Cofiringwith solid fossilfuelsand/ordirectfiringforheatand/orelectricalenergyproduction.

  11. Production of liquid biofuels (second generation bioethanol). Possibilities of utilisation (www.biofuelstp.eu/cellulosic-ethanol.html)

  12. Experimental fields in Croatia Bistra (altitude 144 m) Sljeme (altitude 650 m)

  13. Rhizomes planting 26.4.2011. Sljeme, 2011. Donja Bistra, 2011.

  18. Maretials and metods At the end of vegetation season in the 3thgrowing year (2013.):- plant height - number of shoots per plant- dry matter yield (10-15 days after frost) on 10 m2

  19. Maretials and metods volatile compounds - (CEN/TS 15148:2005), ash (CEN/TS 14775:2009), fixed carbon - (CEN/TS 15148:2005), carbon, hydrogen and nitrogen content (HRN EN 15104:2011), sulphur content (HRN EN 15289:2011), heating values – HHV and LHV (HRN EN 14918:2010), minor and major elements(CEN/TS 15290:2006, CEN/TS15297:2006).

  20. Fieldresults

  21. Laboratoryresults

  22. Potential of Miscanthus x giganteus biomass in Croatia Based on CORINE Land Cover (CLC) digital database there are 541,930 ha of unused agricultural land in Croatia !

  23. Potential biomass yield in tons of dry matter (10 – 12) of Miscanthus x giganteus grass by counties of the Republic of Croatia on poor quality soils

  24. Potential biomass yield in tons of dry matter (15 – 20) of Miscanthus x giganteus grass by counties of the Republic of Croatia on better quality soils

  25. The results confirmed thatMiscanthus x giganteusgrown in Croatiais environment-friendly crop with high-energy properties of biomass which is suitable for production of “green energy”. Conclusion
