Biogas in agriculture

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

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

Biogas Utilisation

Biogas can be transferred via pipeline or as CNG

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)

Bio-Fertilizer• All nutrients are preserved in process

• Nitrogen availibility is increased

• Odour levels are decreased

• Homogenization

• Pathogen reduction
