A US dairy RNG plant recovered $1.33M a year.
The plant wasn't broken. One farm's feedstock was inhibiting it, and nothing on a daily report could say which one.
TL;DR
- The plant wasn't broken — one farm's manure carried an inhibitor that suppressed methane, and nothing on a daily report pointed to which one.
- Claritix Resolve screened each feeding farm and found the source: a clear inhibition signature, methane depressed to 38.1% in test bottles.
- Removing that one input, not dosing to compensate, took monthly output from 5,205 to 7,665 MMBtu — up 47.3%, worth $1.33M a year at $45/MMBtu.
This plant ran every day. It passed its checks, it made gas, and it made money. It was also losing output for reasons that looked like a plant problem, and every farm feeding it looked the same on paper.
Finding which farm
Claritix Resolve screened manure from each feeding farm at different organic loading rates, rather than treating the blended feed as one material. One source stood out: a clear inhibition signature, with most test bottles running silent and methane depressed to 38.1%. That pointed to an upstream contaminant from a single farm, not a generic plant imbalance.
What changed
The correction worked at the source: removing the inhibiting input rather than dosing the digester to compensate for it. That avoids ongoing additive cost and the instability that masking a problem tends to create. Because recovery was re-confirmed under live commercial operation, the gain is a higher production floor, not a one-time rebound. It's the same Claritix Core idea behind every result here: one source of truth surfaces a root cause a monthly average can't show.
- Monthly output rose from 5,205 to 7,665 MMBtu — up 47.3% within three months.
- $111k a month, $1.33M a year, gross at $45/MMBtu on the plant's own gas meter.
- Zero capital spend: the fix was removing an input, not adding equipment.
The honest caveat
The single most useful output wasn't "low gas" — it was knowing which farm to act on. A single-feedstock site with a stable supply has less to find, because it has fewer places for a problem to hide. If you want to know what yours is, send us your data and we will show you your own plant.
