Advanced Methane Emissions Studies for Biogas, RNG, Digesters, and Covered Lagoons

Turn Methane Loss Into Operational Intelligence

Interpolated maps show methane detection sources from 1 ppm-v to 100% methane. Click on any data point for an in-depth view of the area of concern.

Whether you operate an anaerobic digester, covered lagoon, wastewater treatment plant, food waste digester, or renewable natural gas (RNG) facility, every methane leak represents lost revenue, reduced system efficiency, increased greenhouse gas emissions, and potential regulatory risk.

Sniffer Robotics provides advanced methane emissions studies that help operators identify, quantify, and understand methane emissions across their entire operation. By combining the proprietary SnifferDRONE™, high-resolution methane detection system, state-of-the-art handheld equipment, and GIS-based analytics, we deliver actionable data that helps operators:

Locate fugitive methane emissions
Reduce product gas losses
Improve RNG production efficiency
Optimize digester and gas collection performance
Prioritize maintenance using real emissions data
Verify repairs with confidence
Support environmental reporting and sustainability initiatives

Rather than simply finding leaks, Sniffer Robotics provides the intelligence needed to improve operational performance while maximizing renewable energy recovery.

Our methane emissions studies are designed for virtually every type of biogas operation, including:

Dairy digesters
Livestock digesters
Food waste digesters
Industrial anaerobic digesters
Wastewater treatment plants
Covered lagoons
Renewable Natural Gas (RNG) upgrading facilities
Biogas processing plants
Gas collection piping
Compressors, blowers, valves, flanges, and process equipment

From biological gas production through pipeline injection, Sniffer Robotics helps operators understand where methane is escaping and where valuable product gas can be recovered.

Why Conduct a Methane Emissions Study?

The SnifferDRONE inspects digesters at a Wastewater Treatment Facility

Whether you operate an anaerobic digester, covered lagoon, wastewater treatment plant, food waste digester, or renewable natural gas (RNG) facility, every methane leak represents lost revenue, reduced system efficiency, increased greenhouse gas emissions, and potential regulatory risk.

Sniffer Robotics provides advanced methane emissions studies that help operators identify, quantify, and understand methane emissions across their entire operation. By combining the proprietary SnifferDRONE™, high-resolution methane detection system, state-of-the-art handheld equipment, and GIS-based analytics, we deliver actionable data that helps operators:

Locate fugitive methane emissions
Reduce product gas losses
Improve RNG production efficiency
Optimize digester and gas collection performance
Prioritize maintenance using real emissions data
Verify repairs with confidence
Support environmental reporting and sustainability initiatives

Rather than simply finding leaks, Sniffer Robotics provides the intelligence needed to improve operational performance while maximizing renewable energy recovery.

Meet with a Sniffer Rep

The SnifferDRONE™ collects thousands of methane measurements during every survey, creating high-resolution methane maps that show exactly where emissions originate.

Unlike conventional aerial methane sensors that measure methane high above a facility, the patented SnifferDRONE™ samples air only 2–4 inches above the surface using a flexible hose and weighted nozzle. This hyper-local sampling approach identifies methane at its source while minimizing atmospheric dilution, resulting in highly accurate leak localization.

Combined with SnifferVIEW™ GIS software, operators receive:

Full-color methane heat maps
Leak localization
GPS-tagged inspection data
ArcGIS-ready deliverables
Repair verification reports
Historical trend analysis
Cloud-based reporting

Instead of spreadsheets full of numbers, your team receives visual intelligence that makes maintenance decisions faster and easier.

Beyond Leak Detection—Methane Intelligence

By combining aerial inspections of anaerobic digesters with manual inspections of the processing skid, operators gain a comprehensive understanding of facility-wide methane emissions, helping prioritize maintenance, reduce product gas losses, and optimize gas production.

Positive Pressure Plant Inspections

Using state-of-the-art methane detection technologies, Sniffer technicians identify leaks and tag the location.

Methane losses don't stop at the digester.

Sniffer Robotics also performs comprehensive positive-pressure inspections throughout RNG and biogas facilities, including:

Valves
Flanges
Compressors
Blowers
Pressure relief devices
Process piping
Gas conditioning equipment
Upgrading systems

Each leak is photographed, GPS located, physically tagged when appropriate, and quantified in SCFM, allowing operators to estimate product loss and prioritize repairs based on financial impact rather than guesswork.

Finding methane leaks is only part of the picture. Understanding how much methane is being emitted across your entire facility provides the insight needed to prioritize repairs, evaluate system performance, and measure the impact of operational improvements.

Sniffer Robotics partners with Project Canary to convert high-resolution methane mapping data collected by the SnifferDRONE™ into facility-wide methane emissions quantification using flux plane analysis. By combining detailed source localization with advanced atmospheric modeling, operators receive an estimate of total site methane emissions expressed as a single facility-wide emissions rate.

This comprehensive approach gives biogas and RNG operators the ability to:

Estimate total methane emissions from the entire facility
Quantify product gas losses and identify opportunities for recovery
Prioritize repairs based on emissions impact
Measure the effectiveness of maintenance and infrastructure improvements
Track emissions performance over time
Support ESG initiatives and voluntary methane reduction programs
Build confidence in environmental reporting and sustainability goals

Industry-Leading Performance

The combined Sniffer Robotics and Project Canary quantification workflow was recently recognized by FluxLab as one of the top-performing technologies in an independent controlled-release evaluation of methane quantification methods. This recognition demonstrates the accuracy and reliability of combining high-resolution methane mapping with advanced flux plane quantification to estimate total site methane emissions.

Know where methane is escaping. Understand how much is being lost. Make better operational decisions with data you can trust.
