Rentech Inc. said Wednesday that it has received approval from the local government to buy 450 acres in Adams County, Miss., that will be used to construct the company’s synthetic transportation fuels manufacturing operation. No price for the transaction was given.

The Los Angeles-based alternative energy company said in a statement that the operation, to be called the Natchez Strategic Fuels and Chemicals Center, will use petroleum coke or coal supplemented with biomass to produce 25,000 barrels per day of synthetic fuels and specialty chemicals with the capability to produce as much as 50,000 barrels per day. The site isn’t expected to be operational until 2012, Julie Dawoodjee, a spokeswoman for Rentech said.

Rentech also said that the facility will sell the carbon dioxide it captures during the production process to Denbury Resources for enhanced oil recovery and geological sequestration.

Construction should employ about 2,000 workers, Dawoodjee said, and added that when the site is operating, it will employ 200 to 300.

“The site is ideally located with access to multiple feedstocks (coke, coal and biomass),” D. Hunt Ramsbottom, Rentech’s chief executive officer, said in a statement. “The purchase of this site is instrumental in moving this project forward.”
