4. Zijldijk 88 houses 4 company buildings 3 community buildings

6. Conclusion last project

7. Project A Bio digester with enough gas production for the energy demand of Zijldijk Electrical and heat generation and distribution to Zijldijk Compare the different possibilities

8. Energy demand in Zijldijk 1m 3 of natural gas cost € 0,67 the total consumption cost € 134.000 1kWh of electricity cost € 0,21 the total consumption cost € 73.500

9. Anaerobic digestion

10. Anaerobic digestion plant Gas holder Mix Digester Manure storage Gas engine

11. Digestion Controlled biological processes to involve treating organic waste using bacteria in an oxygen-free environment. The anaerobic bacteria produce a methane rich biogas by: Hydrolyze Acidification Methane production This biogas can be used to generate electricity

12. Diet of the digester

13. Biogas Natural Gas calorific value 35MJ/m 3 –Methane 80% to 90% Biogas calorific value 20MJ/m 3 –Methane 55% to 80% –Co 2 45% to 20%

14. Digestate Plants obtain the Nitrogen faster The digestate has an equal mixture Less fertilizer is necessary
