Biogas plant sizing and methane yield calculator.
Estimate daily biogas and digester liquid volume from feedstock, yield and retention assumptions.
Biogas plant sizing and methane yield inputs
Planning estimate only. Waste composition, moisture, temperature, pathogen control, permits, equipment efficiency and local environmental rules must be checked before operating or investing.
Method: This calculator applies the displayed inputs and formula as a transparent planning estimate. Its assumptions are editable, and operational conditions must be verified on site.
Inputs used: Daily wet feedstock = 200 kg; Biogas yield = 0.04 m³/kg; Hydraulic retention time = 40 days
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning estimate only. Waste composition, moisture, temperature, pathogen control, permits, equipment efficiency and local environmental rules must be checked before operating or investing. Rounding and excluded real-world terms can make an external result differ.
How this biogas plant sizing and methane yield calculator works
This calculator applies the displayed inputs and formula as a transparent planning estimate. Its assumptions are editable, and operational conditions must be verified on site.
A worked example
Enter measured farm or facility values to test a realistic scenario before making an operating or purchase decision.
Can this result be used as an operating instruction?
No. It is a planning screen. Feedstock, moisture, temperature, equipment, safety, environmental rules and local expertise determine a real operating plan.
Calculations run on your device. Review your results before exporting or sharing them.
Separate feedstock mass and slurry volume
Daily yield and hydraulic retention should be based on the waste stream and mixing approach you actually use.
Gas safety, digester structure and slurry management require qualified local design.
