In May 2012, Dart Container acquired Illinois-based Solo Cup Company and now has approximately 15,000 employees and more than 45 production, distribution center, and office locations in eight countries. Dart plans to build a new corporate headquarters building and warehouse facility as well as expand existing buildings on its Alaiedon Township campus to integrate Solo Cup corporate and administrative operations into Darts location in Michigan. The employment growth will be fueled both by the relocation of some Solo Cup Company staff from the Chicago area to Mason and new jobs that will be available to Michigan residents.
