Europe’s Biogas Plants Could Become Fertilizer Factories
The fertilizer crisis is usually framed as a natural gas problem. When gas prices rise, ammonia costs rise, fertilizer plants reduce production, and farmers become exposed to a global commodity chain they cannot control.

Key Facts
- Fact 1: The Feedstock Is Already in the Right Place Raw biogas typically contains roughly 55% to 65% methane, with most of the remainder being carbon dioxide.
- Fact 2: A plant producing 1,000 normal cubic metres per hour therefore provides around 600 Nm3 of methane per hour before purification.
- Fact 3: Using standard chemical relationships, this methane stream could theoretically support ammonia production on the order of 25 to 30 tonnes per day, depending on methane content, conversion efficiency, downtime and the treatment of process losses.
- Fact 4: The carbon dioxide already present in the raw gas, plus the CO2 created during reforming, must be separated and either used, stored or released.
The fertilizer crisis is usually framed as a natural gas problem. When gas prices rise, ammonia costs rise, fertilizer plants reduce production, and farmers become exposed to a global commodity chain they cannot control.
That diagnosis is correct but incomplete. Across Europe, thousands of anaerobic digesters are already producing a methane-rich gas close to the farms and food industries that consume fertilizer. Most sites burn it in a combined heat and power unit, upgrade it to biomethane, or flare a small surplus.
