{Charleston, West Virginia}...As part of a restructuring plan, the Dow Chemical Co. has announced it will eliminate about 2,400 jobs and close roughly 20 manufacturing facilities, including its gum base plant in South Charleston, eliminating 13 jobs. The gum base plant produces the material that makes chewing gum chewy. Dow tried to sell the plant a few years ago and entertained a delegation of Brazilians who inspected the facility.
