Milwaukee, Wisconsin – January 29, 2026 – Anguil Environmental Systems, Inc. (Anguil) is pleased to announce that it has been awarded a contract for the supply and manufacture of a Regenerative Thermal Oxidizer (RTO) for the abatement of Ventilation Air Methane (VAM) for GM3’s Appin Mine at Douglas Park, New South Wales, Australia. This highly anticipated project will serve as a demonstration plant to the Australian underground coal mining industry, providing valuable insights and data to inform future projects for the abatement of VAM in Australia. Construction is underway with commissioning scheduled for 4th quarter 2026. The project reflects GM3’s long-term commitment to delivering sustainability across all aspects of their business.
The GM3 Appin RTO will convert methane present in the mine ventilation air to carbon dioxide and water vapor without requiring additional fuel at low methane concentrations. Methane has over 28 times the greenhouse gas potential than CO2. The conversion of methane to CO2 represents a net reduction in greenhouse gas emissions for GM3. Once operational, the demonstration plant is expected to abate approximately 36,000 tons eCO₂ each year.
The Anguil RTO is a proven VAM control device capable of handling a range of methane levels. Anguil has successfully supplied over 25 RTOs worldwide at coal mines. The Anguil RTO design is field proven to guarantee 98+% methane destruction while achieving high thermal efficiency. The Anguil RTO is a modular design and scalable to allow for multiple RTOs to be used in parallel to treat the largest of vent shaft flows.
Anguil will execute the project in collaboration with our Australian VAM RTO partner, Gasco Pty Ltd (Gasco). Based in Melbourne, Gasco will provide local engineering, supervision, service and maintenance support. Gasco has been providing methane abatement systems to coal mines already through their portfolio of products which include coal mine drainage gas flares – both enclosed and elevated.
