Products and brands

Rentech was initially formed in 1981 by Charles Benham and Mark Bohn to develop and commercialize synthetic fuel technologies. In 1991, it incensed its Rentech Process to the Fuel Resources Development Company (Fuelco) to produce diesel fuel from landfill gas at the Synhytech facility in Pueblo, Colorado. Rentech obtained ownership of the facility in 1993. This project failed and was closed at the same year due to lower than expected gas volumes.

In 2000, Rentech acquired a methanol plant at Commerce City, Colorado, which was converted to a gas-to-liquids plant. In mid 2000s, Rentech planned building coal-to-liquids plants in Wyoming, Illinois, Kentucky, and Mississippi.

In 2009, it unveiled plan for construction of a synthetic fuels plant in Rialto, California, and together with ASIG it agreed with 13 airlines to provide synthetic diesel for ground services at Los Angeles International Airport.

In 2010, it made a memorandum of understanding with 14 airlines to provide alternative jet fuel and diesel fuel from its planned biofuels production complex project in Natchez, Mississippi.
