Methane Recovery System (MaRS)

Since 2012 at its Green River, Wyoming plant, Solvay Chemicals saves greenhouse gas emissions by capturing methane release during trona mining. It is the world’s first process to reclaim sodium carbonate waste, turning it into SOLVAir® S300 sodium bicarbonate which is used to treat the emissions of coal-fired power plants.  

The system, the first of its kind in North America, takes gob vent gasses (GVG) comprised mostly of methane as a waste stream generated by mining operations and incinerates them in a controlled fashion, ultimately sending them to manufacturing facilities where the energy can be recovered and used in other processes.
