Resolute Methane · Est. 2024
Next-Generation RTO
Resolute Methane's compact Regenerative Thermal Oxidizer unlocks industrial methane destruction for applications too dilute or too expensive for legacy technology.
Projected lifetime cost vs. legacy RTOs — under $3/tCO₂e above 0.5% methane, and the first viable option below 0.2%.
Self-sustaining operation at the most dilute methane streams (predicted at 50,000 scfm).
Complete high-temperature oxidation. No catalysts. No fouling. Continuous, reliable performance.
The challenge
Methane emissions represent a massive climate liability for heavy industry. While abatement is necessary, traditional technologies fail commercially — too large, too expensive, too limited. The industry doesn't need more science projects; it needs rugged, scalable engineering that works economically in real-world environments.
CO₂e emitted annually from coal mine ventilation air methane alone — largely unmitigated.
Existing RTOs and catalytic approaches are uneconomical at the concentrations found in real industrial settings.
Methane is the most powerful lever for reducing the effects of climate change in the next decade.
The engineering edge
Traditional RTOs destroy methane by heating the emission stream to 870–1000°C in a high-temperature combustion chamber. We leverage the same proven reaction, but wrap it in a clean-sheet hardware architecture: a counterflowing stream of ceramic particles integrated into the combustion chamber absorbs heat from the exhaust and uses it to preheat the incoming stream, replacing the large ceramic beds and cyclic flow-switching of traditional RTOs.
By recovering over 99% of the thermal energy released during methane oxidation, the system operates without external fuel. The inherently higher heat transfer rate of particle-gas exchange, compared to ceramic beds, increases energy recovery while reducing system size and flow resistance.
Industrial applications
Originally developed for coal mines, our highly scalable architecture is applicable across any industry managing dilute methane streams.

Ventilation Air Methane (VAM), drainage systems, and legacy abandoned mine shafts — previously uneconomical to treat at scale.

The only viable, cost-effective aftertreatment for engine slip across natural gas compressors, generators, and related sources.

Broadband destruction of dilute hydrocarbons, ammonia, NOx, and VOCs for manufacturing, painting, and more.

Methane and odor mitigation for landfill gas, manure management, and enclosed animal agriculture.
Mission
Founded to tackle the world's largest unaddressed methane problem. Resolute is commercialising next-generation regenerative thermal oxidation technology to make dilute methane mitigation practical and economical across the heaviest-emitting industries.
The industry doesn't need more science projects. It needs rugged, scalable engineering that works economically — in harsh environments, at scale.
Leadership
Will Sawyer founded Resolute Methane to make dilute methane destruction practical across industrial sites. He brings a background in mechanical engineering, environmental science, high-temperature oxidation, and climate impact assessment to the challenge of mitigating methane streams that are too dilute, variable, or operationally challenging for legacy technologies. Before founding Resolute Methane, he worked on methane catalysis as a postdoctoral associate with Desiree Plata at MIT. He holds degrees from MIT, Dartmouth College, and Wesleyan University.
Partners
We're seeking industry partners to host on-site demonstrations of our transportable system at their facilities throughout 2026 and 2027, validating the system in real-world operating conditions.
