  1. Biogas Potential in Brandenburg (Germany) Dipl.-Geoökol. Sybille Brozio Severine Laufer, Prof. H.-P. Piorr, D. Müller & F. Torkler, University of Applied Sciences Eberswalde December 2006

  2. Situation:Biogas plants Biogas – Plants in Brandenburg (October 2006) agricultural plant waste plant Arable land National unit counties of Brandenburg Planned or under construction: > 70 biogas plants

  3. Method:biomass-yield-model Working groupPIORR (1998)

  4. Method: biomass-yield-model

  5. Method: biomass-yield-model • Regional specific crop rotations (dominant crops of 7 years) • Yield of crops with influences of previous crop • Yields of byproducts (straw and leaves), roots and harvesting residuals Total biomass per hectare / spatial unit

  6. Method:Estimation of bioenergy • Bioenergy per hectare / spatial unit • Scenarios per product lines (biogas, bio ethanol, bio diesel)

  7. Method:Material & biogas content • 1) Silage of • Winter rye: 325 kWel / tons Maize: 335 kWel / tons • - available for biogas production: 50 % of potential yield,- 10 % loss of material during silage process • Statistics of livestock farming: livestock  conversion to amount of liquid manure:liquid manure of cattle: 42 kWel / tonsliquid manure of pigs: 37kWel / tons

  8. Biogas Potential: Silage based • Brandenburg • Efficiency: 32% • Working hours: 7.500 per year • Scaling of the map: size of power plants • On municipality level • Based on: • Silage of maize and winter rye (whole plant)

  9. Biogas Potential:Silage + liquid manure • Brandenburg • Efficiency: 32% • Working hours: 7.500 per year • 300 kWel – plant • On county level • Based on: • Silage of maize and winter rye • Liquid manure 1 – 20 plants 21 – 30 plants 31 – 40 plants 41 – 50 plants > 50 plants

  10. Biogas Potential:Amount of Plants Arable land Potential yield Biogas plants National unit 1.000 t Silage per year 300 kWel 500 kWel • Barnim • Uckermark • Brandenburg 42.213 ha 150.760 ha 12,3 Mio. ha 17 10 62 37 523 314 86,6 343,1 2.364,2

  11. Straw for Bio-ethanol Potential in Brandenburg (Germany) Prof. H.-P. Piorr, Severine Laufer, Dipl.-Geoökol. Sybille Brozio University of Applied Sciences Eberswalde December 2006

  12. New applications for straw • cellulose ethanol process developed by IOGEN to convert straw into Bio-ethanol  Search for potential bio-ethanol facility sites in Germany Background: • straw plays a secondary role in todays agriculture • less important for traditional applications like litter for livestock • Liquid manure husbandry without straw for litter • less livestock on farms • Dominance of cereal cropping with up to 70% of total acreage • Lots of unused resources!

  13. Application of own biomass yield model • With Indices of straw – grain ratio • Only 50% of total straw biomass is available for bioenergy applications • The rest is essential for soil fertility and animal litter

  14. Cereal straw potential Germany • annually available Straw yield potential in dt / ha for Germany (50% of total potential) • conventional farming • Moisture content: 14%

  15. Cereal straw potential in selected federal states

  16. Cereal straw potential Germany • annually available Straw amounts in t per year for Germany on the county level (50% of total potential) • conventional farming • Moisture content: 14% •  validation of data by comparision with statistical data on county level

  17. Straw potential Poland • Additional evaluation of straw potential in the border region to Poland • Based on statistics • Highest productivity in Wielkopolskie (2.209.925,82 t/a) and Dolnośląskie (1.239.614,46 t/a)  50% of total production • But more detailed data required (municipality level)

  18. Scenarios for site in Schwedt 100% rye from the region for Schwedt „Energyrye“: 65% rye from the region for Schwedt, 35% for food & fodder • 800.000 t straw required annually • Scenarios for rye potentials for existing ethanol plant Schwedt (600.000 t/a winter rye) 25% decrease (droughts etc.) 50% decrease (droughts etc.)

  19. Transport and acreage • Based on the average part of rye production in the total cereal production  1,3 Mill tonns of straw are available in this area • For a demand of 800.000 t / a straw the transport distance would be reduced from 89 km to 55 km • More detailed calculations are required if the location Schwedt would be considered for a plant (all cereal straw, rape straw, maize straw...)
