Rentech, Inc. (Rentech) is a provider of clean energy solutions. The Company owns and operates a nitrogen fertilizer plant in East Dubuque, Illinois, that manufactures and sells natural gas-based nitrogen fertilizer products within the corn-belt region in the United States. It is developing energy projects to produce certified synthetic fuels and electric power from carbon-containing materials, such as biomass, waste and fossil resources. Its technologies can produce synthesis gas (syngas) from biomass and waste materials, and convert syngas from its own or other gasification technologies into complex hydrocarbons (the Rentech Process) that are then upgraded into fuels using refining technology that it licenses. In August 2013, Rentech Inc announced that a subsidiary of the Company closed the sale of approximately 450 acres in Natchez, Mississippi to Adams County, Mississippi. In May 2014, the Company acquired New England Wood Pellet.
