  1. ®enbasys gmbh a company of “New Technology for Alternative Energy” Presentation Bangkok 2009-05-26 Kromus, Grasmug

  2. Content • Who is ®enbasys? • Products of ®enbasys • Biogas Production and Technologies • ENBAFERM New Generation Technology • ENBAFERM Examples – Waste, Biofuel, Breweries • ENBAFERM - Demonstration • Conclusions

  3. VTU Holding AG, Frankfurt Stock Exchange 25% Austria Germany Italy Switzerland

  4. Industrial BiotechEnergy PlantsTurn-Key & Customized • Parent company with 200 engineering experts in various industry segments • We are familiar with your processes • …we are taking care of your interfaces • …we are taking care of coordination and integration • …we are handling your challenges • Choosing ®enbasys you rely on • New findings • Fresh ideas

  5. BiotechnologicalEnergy Plants • Anaerobic Digestion increases the efficiency and contributes to climate change deceleration • ®enbasys provides New Technology Generation for • Large volumes • Complex substrates (e.g. organic waste, stillage) • Waste to Energy • AD improves viability and CO2 balance of biofuel production dramatically

  6. ®enbasysProduct-Portfolio

  7. Anaerobic digestion on the upswing • Increasing world energy demand • Growing energy costs and import dependency • Increasing amount of organic residues • Decreasing capacity for landfill • Climate change needs urgent reactions and activities • Low organic matter content of the soil

  8. SOURCES OF WASTE AGRICULTURAL WASTE MUNICIPAL WASTE INDUSTRIAL WASTE/ WASTEWATER

  9. FEEDSTOCKPRODUCT GAS (PRODUCT) FEEDSTOCK / Substrate EFFLUENT ANAEROBIC SLUDGE (PRODUCT)

  10. Water Total Solids (Dry Matter) Organicpartof Total Solids (Volatile Solids)  BIOGAS Basic Characteristic of Substrate

  11. The Idea behind Anaerobic Digestion

  12. BIOPOLYMERS, BIOMASS (carbohydrates, proteins, fats) dissolved polymers, fragments H2 CO2 org. acids alcohols acetic acid ACETIC ACID METHANE, CO2 4-STEP DEGRADATION MODEL hydrolysis acidification acetification methanogenesis

  13. ENBAFERM AD„High Load Hybrid Reactor“ • Patent pending

  14. Influence of Substrate Characteristics • Maintaining cell vitality and groth of new bacterial sludge • Diet of micro-organisms must be supplied • Vital nutrients: Carbon, Nitrogen, Phosphorus, Minerals, Trace-Elements • Limitation of vital nutrients: stop of metabolic activity • Currently controversal discussion about addition of nutrients („wellness-drink“ for microbes) • Example: Washing-water of food industry  nutrients + pH regulation necessary

  15. Theoretical Biogas-Yield

  16. Biogas-Yiel based on Volatile Solids (Organic Matter)

  17. Protein Containing Waste / Waste-Water • H2S in biogas • NH4+ in sludge and effluent • foaming as a result of gas mixing • metabolism-generated alkalinity

  18. Fat Containing Waste / Wastewater • scum layers • bioavailability • toxicity • slow degradation

  19. MAIN PROCESS- AND SUBSTRATE- RELATED FACTORS • temperature • mixing (process configuration) • retention time (loading rate) • substrate (type, composition) • C:N:P -relation • total solids • concentration • sulfur compounds • pH • organic acids

  20. MSW OFMSW • variability • inerts • expensive pretreatment • depends on attitude of community

  21. Complete Stirred Reactor • Mixer (Agitator) (e.g. CSTR) • Hydraulic Mixing • Tubular reactor with paddles

  22. High Load Systems without particles and low COD UASB = Upflow Anaerobic Sludge Blanket Application: Washing-Waters, WW paper industry,

  23. ENBAFERM New Technology UASB CSTR

  24. High Performance Process TechnologyENBAFERM • Low Hydraulic Retention Time low demand for fermenter volume • Prevention of Foam and Floating Layershigh loading rates • Intense Contact between Substrate and Microorganismshigh degradation rates and rapid gas production

  25. ®enbasys: AD of Organic Waste

  26. Waste treatment Logistics Sorting / Crushing Screening / Pressing Sand removal Mixing Energy Biogas

  27. ®enbasys: AD of Organic Waste Fractions • Largest Facility of Europe (Total 350,000 t/a) • Stable with High Loading Rate • No foam, no break down • Total Nitrogen about 7 to 8 g/l • Sediments are removed  no shut down  Waste to Energy at perfection • Sister installation is open now • AD will be installed
