Biogas systems

Almost any organic material can be processed with anaerobic digestion including biodegradable waste materials such as vegetation, agricultural waste, waste of agrifood industry, wastewater treatment of sludge plants, household waste, sewage (the treatment of human waste), garbage product (landfills), animal by-products and farmyard manure.

Process of conversion materials into biogas in anaerobic digestion

Biogas may be used to produce heat and power:

The cleaned methane can be piped to an engine or turbine and generator to produce electricity or sent through the pipeline as a usable gas.

Biogas system applications

• Cooking and lighting
• Fuel of engines
• Product electricity
• Drying agricultural products
• Drying bricks and clay

Biogas system features

• Easer availability and extraction compared to fossil fuels
• Cost-effective, especially for the slaughterhouse, cattle and poultry farms and dairy industries
• Easily convertible to electrical energy with minimum energy loss
• Productivity by selling electricity to support grid
• Barrier to methane emission into the atmosphere and nitrate leakage into the groundwater resources
• Manure quality improvement by increasing Nitrogen to nitrate ratio due to Mezofill bacteria activity
• Higher nitrogen absorption by crops, especially pastures
