NORTH SIOUX CITY -- A bioscience firm has purchased a large tract of land in North Sioux City for an undisclosed future development project.
Hepar BioScience, based in nearby Jefferson, S.D., paid $402,500, or about $8,000 per acre, for the 50-acre tract in the Flynn Business Park, according to Union County records.
The company develops biochemicals isolated from animal byproducts.
Hepar president Mark Nylen did not immediately return a call to the Journal.
Kory Menken, executive director of the North Sioux City Economic Development Corp., told the Journal he was not at liberty to discuss Hepar's plans. But Menken did confirm the NSEC released its exclusive purchase option on the 50 acres to help advance what he described as a major development.
Bounded by Highway 105 to the west and Waters Road on the north, the site encompasses about a third of the 160-acre Flynn Business Park, which is home to another bioscience firm, called Nutraferma, which turns soy into animal feeds.
Mark Nylen and his wife, Mary Ellen, have donated to a number of community endeavors and charities, including the June E. Nylen Cancer Center, named for Mark's mother, who died of cancer. More recently, the couple made a significant gift that led to the opening of the Nylen Science Center at Dakota Valley High School.
