Rentech, Inc. develops technologies and projects that transforms under-utilized energy resources into an alternative fuel and chemicals. The Rentech Process, based on Fischer-Tropsch (FT) chemistry, is a technology that converts synthesis gas (syngas), which can be manufactured from a variety of waste, biomass and fossil resources, into hydrocarbons. These hydrocarbons can be processed and upgraded into ultra-clean synthetic fuels, such as military and commercial jet fuels and ultra low sulphur diesel, as well as specialty waxes and chemicals. The Company also owns an operating natural gas-based nitrogen fertilizer manufacturing plant in Illinois. In July 2009, the Company completed the acquisition of SilvaGas Corporation and its commercial-scale biomass gasification technology.
