1 Danish Biogas Technology Co-digestion for Energy and Environment
Paris, France, Monday April 14th 2008

2 What can Danish biogas technology do?
Handle waste Reduce odour Increase nutrient accessibility Reduce nutrient leaching Provide CO2- free energy Provide added revenue Enrich the community Reduce GHG emissions

3 The Technology: Anaerobic digestion
Mesophilic or Thermophilic process Fully mixed digesters Co-digestion concept Proven in Denmark We have 25 years of experience World class R&D

4 History and Future of Danish Biogas
Drivers Milestones

5 Biogas Plants in Operation
m3 biomass processed at: Large plants Animal manure Organic waste Total Farm Plants Total annual  20 Large Biogas Plants  57 Farm based Biogas Plants

6 What is Biogas?

7 Input Composition for the Danish Community Biogas Plants 2001

8 Biogas Plant Design

9 Biogas Technology Pre-treatment Digestion After treatment End use Gas
Mixing Macerating Hygienisation/ sterilisation +/- other pre-treatment: e.g. concentration Digestion After treatment Store Separate Upgrade End use Land application Move and apply Transport market / or disposal Gas Direct use for CHP Upgrade for natural gas grid Vehicle fuel

10 Ongoing projects April 2008
