New here?Quick start for Landfill Gas— typical inputs, what to ask the host, red flags
Typical inputs
Flow: 100–2,000 scfm at the wellhead for a 10–50 acre site; >2,000 scfm typically only at active municipal landfills.
CH₄ %: 45–55% CH₄ is typical; below 40% suggests well-field tuning issues or end-of-life cells.
What to ask the host
- Most recent wellhead flow + CH₄ % from the gas survey (last 6 months).
- Whether the site is under a flare consent order or NSPS Subpart Cf/XXX trigger.
- Years operated, years until closure, and waste-in-place tonnage for LandGEM.
- Existing flare destruction efficiency (affects vs-Flare counterfactual).
Red-flag inputs
- scfm without a CH₄ % — biogas energy is half the story.
- Single spot measurement instead of a 30-day average.
- H₂S > 500 ppm without a scrubber line item.

Standard cubic feet per minute at wellhead
> 200 ppm requires H₂S scrubber (adds ~$25K capex)
Typical range: recip 32–40%, microturbine 26–33%
Landfill Gas sites: typical range varies — include planned maintenance
Commercial-scale deployment: 432 × S19 XP across 11 containers. Grid-independent behind-meter system. Dual connectivity recommended (Starlink + LTE backup).
