Dr. Wes Parish developed fuel catalysts in 1986 to modify combustion in engines and open flames. His Greenfoot catalyst was created based on his earlier work modifying solid rocket propellant burn rates. In 2007, a new division was established to market the Greenfoot catalyst. Testing showed a 90% customer retention rate. Greenfoot Fuel Tech was later formed in 2009 to be the commercial entity bringing Dr. Parish's research to market through technically advanced teams. The Greenfoot catalyst modifies combustion to reduce deposits, emissions, and fuel consumption while extending equipment life.
