Ardagh Group has been awarded five Energy Star plant certifications from the Environmental Protection Agency (EPA) in the USA for its energy performance.

As a result of certifying five facilities in 2014, Ardagh Group has also received special recognition as a Member of the EPA’s Certification Nation.

The five Ardagh Group, Glass plants, located in Burlington, Wis.; Dunkirk, Ind.; Madera, Calif.; Milford, Mass.; and Sapulpa, Okla., were the only glass container facilities in the US to earn the recognition.

It places them within the top 25% of similar facilities nationwide for energy efficiency performance levels set by the EPA.

John Riordan, President and CEO of Ardagh Group’s North American Glass division, said: “We’ve made significant contributions across our organisation to embrace energy efficiency and achieve company-wide sustainability initiatives.

"This award proves our hard work and dedication to these processes and procedures.”

The five facilities have improved energy performance by upgrading and optimising furnaces, utilising recycled glass, installing energy-efficient lighting fixtures and repairing air compressor leaks, among several other energy-saving initiatives.
