Ardagh plans to invest $71 million at its Winchester, Indiana, USA plant.

The money will be spent on making improvements to the 78-year-old facility that employs 400 people.

The upgrades will be made over three years and be aided by a slew of incentives from state and area economic development groups.

“This level of investment in a single glass-manufacturing facility in such a brief period of time is unprecedented for Ardagh Group and extremely rare in our industry,” John Riordan, CEO of Ardagh Group Glass North America, said.

Built in 1937, the facility specialises in manufacturing glass containers for the food and spirits markets. The plant was owned by Anchor Glass Container Corp before Ardagh Group purchased the company for $880 million in August 2012.

Incentive agreements for the project include a $6.1 million tax abatement over 10 years from the city of Winchester and a grant of $300,000 for local equipment purchases and training of employees associated with the project from the Randolph Economic Development Corp.

In addition, the Indiana Economic Development Corp. has offered up to $1 million in conditional tax credits and up to $200,000 in training grants, according to Ardagh.
