1. Biogas in agriculture

2. Biogas production Biogas is produced when organic material is degraded in oxygen free environment Microbes utilise material as energy source Organic material is fermented in same manner as in alcohol or other fermented food Key elements in efficient production is heating and mixing of material

3. Biogas production Energy produced in form of biogas, 60 % methane and 40 % carbon dioxide Methane = natural gas Utilisation - Heat production - Electricity production - Vehicle fuel - Natural gas grid

4. Biogas Utilisation Biogas can be transferred via pipeline or as CNG

5. Biogas production Biogas tecnhology is utilised to treat wastes from agriculture, food industry as well as municipal biowastes and -sludges Possibility for income from gate fees (waste treatmen compensation)

6. Bio-Fertilizer All nutrients are preserved in process Nitrogen availibility is increased Odour levels are decreased Homogenization Pathogen reduction
