ELK Group International, a Pennsylvania-based designer and importer of lighting fixtures, is outfitting a former yarn mill in Sylvania as a distribution center projected to employ more than 100 people. Georgia Department of Economic Development and Screven County Development Authority officials announced the project last week as a new industry for Screven County. The building ELK is occupying, with a reported investment of $2 million, is the former Sylvania Yarn Systems mill, which closed in December 2009 with the loss of 150 jobs.
