Rules of Thumb
• 1 m³ pig manure (PM) produces about 30 m³ of
biogas
• 1 ton of corn produces about 180 m³ of biogas
• Mixture: about 2 to 1 (2 ton PM/1 ton Corn), total
dry matter content must be smaller than 20%.
• 1 m³ biogas generates about 1.8 kW of electricity.
• Typical investment (Netherlands) :
– 190 kWe installation: € 0,6 million
– 1000 kWe installation: € 2.5 million
